I'm trying to get an old smarty filter working without success. It takes a set of words from the URL and should highlight them, but while 'smarty_output_highlight' is being called it's only being passed 'en', the language code rather than the text block to be processed
Mistral Small 3:
It sounds like you're dealing with a Smarty template engine issue where a custom filter is not receiving the expected parameters. Let's break down the steps to troubleshoot and potentially fix this issue.
### Step-by-Step Troubleshooting
1. **Check the Filter Definition**:
Ensure that the filter is correctly defined in your Smarty configuration. The filter should be registered to process the text block.
```php
$smarty->registerFilter('output', 'smarty_output_highlight');
```
2. **Filter Function**:
Verify that the `smarty_output_highlight` function is correctly implemented to handle the text block. The function should accept the text block as a parameter.
```php
function smarty_output_highlight($text, $smarty) {
// Your highlighting logic here
// For example, highlighting words from the URL
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
3. **URL Parameters**:
Ensure that the URL parameters are correctly set and accessible. For example, if you are passing `highlight` parameters in the URL, they should be accessible via `$_GET['highlight']`.
```php
// Example URL: http://example.com/page?highlight=word1,word2
```
4. **Debugging**:
Add debugging statements to check what parameters are being passed to the filter.
```php
function smarty_output_highlight($text, $smarty) {
echo "Text: " . $text . "<br>";
echo "Language: " . $smarty->getConfigVars('language') . "<br>";
// Your highlighting logic here
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
5. **Template Usage**:
Ensure that the template is correctly using the filter. For example:
```smarty
{assign var="text" value="This is a sample text with words to highlight."}
{$text|smarty_output_highlight}
```
### Example Implementation
Here is a complete example to illustrate the process:
**PHP Script (index.php)**:
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
$smarty->registerFilter('output', 'smarty_output_highlight');
$smarty->display('highlight.tpl');
```
**Filter Function (highlight_filter.php)**:
```php
<?php
function smarty_output_highlight($text, $smarty) {
// Debugging output
echo "Text: " . $text . "<br>";
echo "Language: " . $smarty->getConfigVars('language') . "<br>";
// Highlighting logic
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
**Template (templates/highlight.tpl)**:
```smarty
{assign var="text" value="This is a sample text with words to highlight."}
{$text|smarty_output_highlight}
```
### Conclusion
By following these steps, you should be able to diagnose why the `smarty_output_highlight` function is only receiving the language code instead of the text block. Ensure that the filter is correctly registered, the function is implemented to handle the text block, and the template is correctly using the filter.

User prompt 2 of 8 - 11/08/2025, 15:10:51:
smarty_output_highlight is part of a custom BitweaverExtension addition to smarty 5. It is loaded using addDefaultModifiers when 'highlight' is included in the URL, but debugging the code it's not being given the full text, and as far as I can tell, only one parameter is passed to it and it's not the block of text that is going to be the central area of the rendered page.
Mistral Small 3:
Given that `smarty_output_highlight` is part of a custom BitweaverExtension addition to Smarty 5 and is loaded using `addDefaultModifiers` when 'highlight' is included in the URL, let's delve deeper into the issue. The problem seems to be that the filter is not receiving the full text block as expected.
### Steps to Diagnose and Fix the Issue
1. **Check the `addDefaultModifiers` Implementation**:
Ensure that `addDefaultModifiers` is correctly adding the `smarty_output_highlight` filter to the list of default modifiers.
```php
if (isset($_GET['highlight'])) {
$smarty->addDefaultModifiers('smarty_output_highlight');
}
```
2. **Filter Function Implementation**:
Verify that the `smarty_output_highlight` function is correctly implemented to handle the text block. The function should accept the text block as a parameter.
```php
function smarty_output_highlight($text, $smarty) {
// Debugging output
echo "Text: " . $text . "<br>";
echo "Language: " . $smarty->getConfigVars('language') . "<br>";
// Highlighting logic
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
3. **Template Usage**:
Ensure that the template is correctly using the filter. For example:
```smarty
{assign var="text" value="This is a sample text with words to highlight."}
{$text|smarty_output_highlight}
```
4. **Debugging the Filter**:
Add debugging statements to check what parameters are being passed to the filter.
```php
function smarty_output_highlight($text, $smarty) {
// Debugging output
echo "Text: " . $text . "<br>";
echo "Language: " . $smarty->getConfigVars('language') . "<br>";
// Highlighting logic
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
5. **Check Smarty Configuration**:
Ensure that the Smarty configuration is correctly set up to handle default modifiers. This includes checking the Smarty version and any custom configurations that might affect the behavior of default modifiers.
### Example Implementation
Here is a complete example to illustrate the process:
**PHP Script (index.php)**:
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
if (isset($_GET['highlight'])) {
$smarty->addDefaultModifiers('smarty_output_highlight');
}
$smarty->display('highlight.tpl');
```
**Filter Function (highlight_filter.php)**:
```php
<?php
function smarty_output_highlight($text, $smarty) {
// Debugging output
echo "Text: " . $text . "<br>";
echo "Language: " . $smarty->getConfigVars('language') . "<br>";
// Highlighting logic
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
**Template (templates/highlight.tpl)**:
```smarty
{assign var="text" value="This is a sample text with words to highlight."}
{$text|smarty_output_highlight}
```
### Conclusion
By following these steps, you should be able to diagnose why the `smarty_output_highlight` function is not receiving the full text block. Ensure that the filter is correctly registered, the function is implemented to handle the text block, and the template is correctly using the filter. If the issue persists, consider checking the Smarty documentation or community forums for any version-specific issues or additional configuration requirements.

OK lets try something simpler ...
"<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code.</p>"
Mistral Small 3:
Sure, let's create a simpler example to ensure that the `smarty_output_highlight` filter works as expected. We'll focus on highlighting specific words in a given text block.
### Simplified Example
1. **PHP Script (index.php)**:
This script sets up Smarty and registers the `smarty_output_highlight` filter.
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
// Register the custom filter
$smarty->registerFilter('output', 'smarty_output_highlight');
// Display the template
$smarty->display('highlight.tpl');
```
2. **Filter Function (highlight_filter.php)**:
This function highlights specific words in the text block.
```php
<?php
function smarty_output_highlight($text, $smarty) {
// Debugging output
echo "Text: " . $text . "<br>";
// Highlighting logic
$words = explode(',', $_GET['highlight']);
foreach ($words as $word) {
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
3. **Template (templates/highlight.tpl)**:
This template contains the text block that will be processed by the filter.
```smarty
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Highlight Example</title>
<style>
.highlight {
background-color: yellow;
}
</style>
</head>
<body>
<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code.</p>
</body>
</html>
```
### Testing the Example
1. **Run the PHP Script**:
Ensure that your web server is running and navigate to the script in your browser. For example, if your script is located at `http://localhost/index.php`, open that URL.
2. **Pass Highlight Parameters**:
Append the `highlight` parameter to the URL to specify the words you want to highlight. For example:
```
http://localhost/index.php?highlight=novelactivist,page
```
3. **Expected Output**:
The text block in the template should be rendered with the specified words highlighted. For example:
```
<p>Testing <span class="highlight">novelactivist</span> <span class="highlight">new</span> page for indexing as it had been disabled while fixing other areas of the code.</p>
```
### Conclusion
This simplified example should help you verify that the `smarty_output_highlight` filter is working correctly. If the words are highlighted as expected, you can then apply this logic to more complex scenarios. If you encounter any issues, the debugging output in the filter function should help you identify where the problem lies.
--------------------
User prompt 4 of 8 - 11/08/2025, 16:05:34:
Hit bloody return too soon! The question is how do I add a span to
"<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code.</p>" wrapping the word to highlight which is novelactivist, but code should allow for a variable number of words.
Mistral Small 3:
Got it! Let's create a Smarty filter that wraps specific words in a `<span>` tag. We'll make sure the filter can handle a variable number of words to highlight.
### Steps to Implement the Filter
1. **Register the Filter**:
Ensure the filter is registered with Smarty.
2. **Implement the Filter Function**:
Create a function that takes the text block and the words to highlight, then wraps each word in a `<span>` tag.
3. **Use the Filter in the Template**:
Apply the filter to the text block in the template.
### Example Implementation
1. **PHP Script (index.php)**:
This script sets up Smarty and registers the `highlight_words` filter.
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
// Register the custom filter
$smarty->registerFilter('output', 'highlight_words');
// Display the template
$smarty->display('highlight.tpl');
```
2. **Filter Function (highlight_filter.php)**:
This function highlights specific words in the text block.
```php
<?php
function highlight_words($text, $smarty) {
// Get the words to highlight from the URL parameter
$words = isset($_GET['highlight']) ? explode(',', $_GET['highlight']) : [];
// Highlighting logic
foreach ($words as $word) {
$word = trim($word);
$text = preg_replace('/b' . preg_quote($word, '/') . 'b/i', '<span class="highlight">$0</span>', $text);
}
return $text;
}
```
3. **Template (templates/highlight.tpl)**:
This template contains the text block that will be processed by the filter.
```smarty
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Highlight Example</title>
<style>
.highlight {
background-color: yellow;
}
</style>
</head>
<body>
<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code.</p>
</body>
</html>
```
### Testing the Example
1. **Run the PHP Script**:
Ensure that your web server is running and navigate to the script in your browser. For example, if your script is located at `http://localhost/index.php`, open that URL.
2. **Pass Highlight Parameters**:
Append the `highlight` parameter to the URL to specify the words you want to highlight. For example:
```
http://localhost/index.php?highlight=novelactivist,page
```
3. **Expected Output**:
The text block in the template should be rendered with the specified words highlighted. For example:
```
<p>Testing <span class="highlight">novelactivist</span> new <span class="highlight">page</span> for indexing as it had been disabled while fixing other areas of the code.</p>
```
### Conclusion
This implementation ensures that the `highlight_words` filter can handle a variable number of words to highlight. The filter wraps each specified word in a `<span>` tag with a class of `highlight`, which you can style as needed. This should meet your requirements for highlighting words in a text block.
--------------------

One step forward, but another back. Now I know why the original code is so complex ;) Need to avoid adding span when there is a url involved ;) And probably a few more cases as well ...
Mistral Small 3:
Understood! To handle more complex scenarios, such as avoiding adding `<span>` tags around URLs or other specific cases, we need to enhance the filter function. We'll add logic to check for URLs and other patterns before wrapping words in `<span>` tags.
### Enhanced Filter Implementation
1. **PHP Script (index.php)**:
This script sets up Smarty and registers the `highlight_words` filter.
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
// Register the custom filter
$smarty->registerFilter('output', 'highlight_words');
// Display the template
$smarty->display('highlight.tpl');
```
2. **Filter Function (highlight_filter.php)**:
This function highlights specific words in the text block, avoiding URLs and other specific cases.
```php
<?php
function highlight_words($text, $smarty) {
// Get the words to highlight from the URL parameter
$words = isset($_GET['highlight']) ? explode(',', $_GET['highlight']) : [];
// Define a pattern to match URLs
$urlPattern = '/b(https?://[^s]+)b/';
// Highlighting logic
foreach ($words as $word) {
$word = trim($word);
// Avoid highlighting words that are part of a URL
$text = preg_replace_callback('/b' . preg_quote($word, '/') . 'b/i', function($matches) use ($urlPattern) {
if (preg_match($urlPattern, $matches[0])) {
return $matches[0];
} else {
return '<span class="highlight">' . $matches[0] . '</span>';
}
}, $text);
}
return $text;
}
```
3. **Template (templates/highlight.tpl)**:
This template contains the text block that will be processed by the filter.
```smarty
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Highlight Example</title>
<style>
.highlight {
background-color: yellow;
}
</style>
</head>
<body>
<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code. Visit <a href="https://example.com">this link</a> for more information.</p>
</body>
</html>
```
### Testing the Example
1. **Run the PHP Script**:
Ensure that your web server is running and navigate to the script in your browser. For example, if your script is located at `http://localhost/index.php`, open that URL.
2. **Pass Highlight Parameters**:
Append the `highlight` parameter to the URL to specify the words you want to highlight. For example:
```
http://localhost/index.php?highlight=novelactivist,page
```
3. **Expected Output**:
The text block in the template should be rendered with the specified words highlighted, except for words that are part of a URL. For example:
```
<p>Testing <span class="highlight">novelactivist</span> new <span class="highlight">page</span> for indexing as it had been disabled while fixing other areas of the code. Visit <a href="https://example.com">this link</a> for more information.</p>
```
### Conclusion
This enhanced implementation ensures that the `highlight_words` filter can handle more complex scenarios, such as avoiding adding `<span>` tags around URLs. The filter uses a callback function with `preg_replace_callback` to check if a word is part of a URL before wrapping it in a `<span>` tag. This approach can be extended to handle other specific cases as needed.
--------------------
User prompt 6 of 8 - 11/08/2025, 18:42:41:
Little rejig please need to pass $i into the function
$source = preg_replace_callback('/b' . preg_quote($word, '/') . 'b/i',
function($matches) use ($urlPattern) {
if (preg_match($urlPattern, $matches[0])) {
return $matches[0];
} else {
return '<span style="font-weight:bold;color:black;background-color:'.$colorArr[$i].';">' . $matches[0] . '</span>';
}
}, $source);
}
Mistral Small 3:
To pass the `$i` variable into the callback function, you can use the `use` keyword to include it in the closure. This allows you to access `$i` within the callback function. Additionally, you need to ensure that `$colorArr` is defined and accessible within the scope of the filter function.
Here's the updated implementation:
1. **PHP Script (index.php)**:
This script sets up Smarty and registers the `highlight_words` filter.
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
// Register the custom filter
$smarty->registerFilter('output', 'highlight_words');
// Display the template
$smarty->display('highlight.tpl');
```
2. **Filter Function (highlight_filter.php)**:
This function highlights specific words in the text block, avoiding URLs and other specific cases, and uses a color array for styling.
```php
<?php
function highlight_words($text, $smarty) {
// Get the words to highlight from the URL parameter
$words = isset($_GET['highlight']) ? explode(',', $_GET['highlight']) : [];
// Define a pattern to match URLs
$urlPattern = '/b(https?://[^s]+)b/';
// Define an array of colors for highlighting
$colorArr = ['yellow', 'lightblue', 'lightgreen', 'lightcoral', 'lightgray'];
// Highlighting logic
foreach ($words as $i => $word) {
$word = trim($word);
// Avoid highlighting words that are part of a URL
$text = preg_replace_callback('/b' . preg_quote($word, '/') . 'b/i', function($matches) use ($urlPattern, $colorArr, $i) {
if (preg_match($urlPattern, $matches[0])) {
return $matches[0];
} else {
return '<span style="font-weight:bold;color:black;background-color:' . $colorArr[$i % count($colorArr)] . ';">' . $matches[0] . '</span>';
}
}, $text);
}
return $text;
}
```
3. **Template (templates/highlight.tpl)**:
This template contains the text block that will be processed by the filter.
```smarty
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Highlight Example</title>
</head>
<body>
<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code. Visit <a href="https://example.com">this link</a> for more information.</p>
</body>
</html>
```
### Testing the Example
1. **Run the PHP Script**:
Ensure that your web server is running and navigate to the script in your browser. For example, if your script is located at `http://localhost/index.php`, open that URL.
2. **Pass Highlight Parameters**:
Append the `highlight` parameter to the URL to specify the words you want to highlight. For example:
```
http://localhost/index.php?highlight=novelactivist,page
```
3. **Expected Output**:
The text block in the template should be rendered with the specified words highlighted, except for words that are part of a URL. The highlighted words will have different background colors based on the `$colorArr` array. For example:
```
<p>Testing <span style="font-weight:bold;color:black;background-color:yellow;">novelactivist</span> new <span style="font-weight:bold;color:black;background-color:lightblue;">page</span> for indexing as it had been disabled while fixing other areas of the code. Visit <a href="https://example.com">this link</a> for more information.</p>
```
### Conclusion
This implementation ensures that the `highlight_words` filter can handle more complex scenarios, such as avoiding adding `<span>` tags around URLs and using different colors for highlighting. The filter uses a callback function with `preg_replace_callback` to check if a word is part of a URL before wrapping it in a `<span>` tag. The `$i` variable is passed into the callback function using the `use` keyword, allowing for dynamic styling based on the index of the word.

User prompt 7 of 8 - 11/08/2025, 19:47:05:
Am slowly getting to understand all the extra bits in the original code, but
// get all text that needs to be highlighted
$extractor = "#<divs+class=.?body[^>]*>.*?<!--s*ends*.?bodys*-->#is";
preg_match_all( $extractor, $source, $match );
$highlights = $match[0];
is failing to create an initial string ... if I copy $source to $highlights[0] the code starts working but what is the $extractor designed to do? Bearing in mind I am USING highlight as a function now as Smarty no longer allows the page wide output filter
Mistral Small 3:
The `$extractor` regular expression is designed to match a specific section of HTML content within the `$source` string. This section is defined by a `<div>` element with a class of `body` and ends with a comment `<!-- end .body -->`. The regular expression is intended to capture all the text between these two markers.
Let's break down the regular expression:
- `#<divs+class=.?body[^>]*>`: This part matches a `<div>` element with a class attribute that contains `body`. The `class=.?body` part allows for optional characters before `body` (e.g., `class="body"` or `class="somebody"`).
- `.*?`: This part matches any character (except for line terminators) between zero and unlimited times, as few times as possible (non-greedy).
- `<!--s*ends*.?bodys*-->`: This part matches the closing comment `<!-- end .body -->`, allowing for optional spaces and a possible dot before `body`.
The `is` flags at the end of the regular expression mean:
- `i`: Case-insensitive matching.
- `s`: Dot matches newline characters.
### Debugging the Issue
If the `$extractor` is failing to create an initial string, there are a few things to check:
1. **Ensure the HTML Structure**:
Make sure the HTML structure in `$source` matches the pattern expected by the regular expression. The `<div>` element with the class `body` and the closing comment `<!-- end .body -->` must be present.
2. **Check for Errors**:
Add debugging statements to check if the regular expression is matching the expected content.
3. **Simplify the Regular Expression**:
Simplify the regular expression to see if it matches the expected content. Gradually add complexity back to identify the issue.
### Example Implementation
Let's create a simplified example to illustrate the process:
1. **PHP Script (index.php)**:
This script sets up Smarty and registers the `highlight_words` filter.
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
// Register the custom filter
$smarty->registerFilter('output', 'highlight_words');
// Display the template
$smarty->display('highlight.tpl');
```
2. **Filter Function (highlight_filter.php)**:
This function highlights specific words in the text block, avoiding URLs and other specific cases, and uses a color array for styling.
```php
<?php
function highlight_words($text, $smarty) {
// Get the words to highlight from the URL parameter
$words = isset($_GET['highlight']) ? explode(',', $_GET['highlight']) : [];
// Define a pattern to match URLs
$urlPattern = '/b(https?://[^s]+)b/';
// Define an array of colors for highlighting
$colorArr = ['yellow', 'lightblue', 'lightgreen', 'lightcoral', 'lightgray'];
// Extract the section to highlight
$extractor = "#<divs+class=.?body[^>]*>.*?<!--s*ends*.?bodys*-->#is";
preg_match_all($extractor, $text, $match);
$highlights = $match[0];
// Debugging output
echo "Extracted highlights: " . implode(", ", $highlights) . "<br>";
// Highlighting logic
foreach ($words as $i => $word) {
$word = trim($word);
// Avoid highlighting words that are part of a URL
foreach ($highlights as &$highlight) {
$highlight = preg_replace_callback('/b' . preg_quote($word, '/') . 'b/i', function($matches) use ($urlPattern, $colorArr, $i) {
if (preg_match($urlPattern, $matches[0])) {
return $matches[0];
} else {
return '<span style="font-weight:bold;color:black;background-color:' . $colorArr[$i % count($colorArr)] . ';">' . $matches[0] . '</span>';
}
}, $highlight);
}
}
// Replace the original highlights with the modified ones
$text = preg_replace($extractor, implode("", $highlights), $text, 1);
return $text;
}
```
3. **Template (templates/highlight.tpl)**:
This template contains the text

No ... it's failing because I am NOW using it inside the Body block, so I can strip that and simply jump staring into the rest of the code ;)
Mistral Small 3:
Got it! Since you are now using the `highlight_words` function inside the body block, you can simplify the process by directly working with the content within the body block. This means you can skip the extraction step and start highlighting words directly within the provided text.
Here's how you can modify the implementation to work directly with the content inside the body block:
1. **PHP Script (index.php)**:
This script sets up Smarty and registers the `highlight_words` filter.
```php
<?php
require('path/to/smarty/libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir('templates');
$smarty->setCompileDir('templates_c');
$smarty->setConfigDir('configs');
$smarty->setCacheDir('cache');
// Register the custom filter
$smarty->registerFilter('output', 'highlight_words');
// Display the template
$smarty->display('highlight.tpl');
```
2. **Filter Function (highlight_filter.php)**:
This function highlights specific words in the text block, avoiding URLs and other specific cases, and uses a color array for styling.
```php
<?php
function highlight_words($text, $smarty) {
// Get the words to highlight from the URL parameter
$words = isset($_GET['highlight']) ? explode(',', $_GET['highlight']) : [];
// Define a pattern to match URLs
$urlPattern = '/b(https?://[^s]+)b/';
// Define an array of colors for highlighting
$colorArr = ['yellow', 'lightblue', 'lightgreen', 'lightcoral', 'lightgray'];
// Highlighting logic
foreach ($words as $i => $word) {
$word = trim($word);
// Avoid highlighting words that are part of a URL
$text = preg_replace_callback('/b' . preg_quote($word, '/') . 'b/i', function($matches) use ($urlPattern, $colorArr, $i) {
if (preg_match($urlPattern, $matches[0])) {
return $matches[0];
} else {
return '<span style="font-weight:bold;color:black;background-color:' . $colorArr[$i % count($colorArr)] . ';">' . $matches[0] . '</span>';
}
}, $text);
}
return $text;
}
```
3. **Template (templates/highlight.tpl)**:
This template contains the text block that will be processed by the filter.
```smarty
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Highlight Example</title>
</head>
<body>
<div class="body">
<p>Testing novelactivist new page for indexing as it had been disabled while fixing other areas of the code. Visit <a href="https://example.com">this link</a> for more information.</p>
</div>
<!-- end .body -->
</body>
</html>
```
### Testing the Example
1. **Run the PHP Script**:
Ensure that your web server is running and navigate to the script in your browser. For example, if your script is located at `http://localhost/index.php`, open that URL.
2. **Pass Highlight Parameters**:
Append the `highlight` parameter to the URL to specify the words you want to highlight. For example:
```
http://localhost/index.php?highlight=novelactivist,page
```
3. **Expected Output**:
The text block in the template should be rendered with the specified words highlighted, except for words that are part of a URL. The highlighted words will have different background colors based on the `$colorArr` array. For example:
```
<div class="body">
<p>Testing <span style="font-weight:bold;color:black;background-color:yellow;">novelactivist</span> new <span style="font-weight:bold;color:black;background-color:lightblue;">page</span> for indexing as it had been disabled while fixing other areas of the code. Visit <a href="https://example.com">this link</a> for more information.</p>
</div>
<!-- end .body -->
```
### Conclusion
By simplifying the process and directly working with the content inside the body block, you can avoid the complexity of extracting the content with a regular expression. This approach ensures that the `highlight_words` function can handle the highlighting logic directly within the provided text.
