Convert Content of Pre-Tags in HTML-Code

Posted in: WordPress Hacks

There are two different ways to display a source code instead of executing a source code in a post or page. Depending on preferences which HTML tag is defined in the style sheet and provided with formatting, code fragments are either declared by <code> or <pre>. In some cases, combining the blogger even both tags.

Conversion of special characters

If you want to use the pre Tag, then you have to take care that the code snippets, while parsing, are not executable. HTML-Entity is the solution.

Two options are available: One, manually, such as search and replace before pasting into the editor (HTML-Entities-table). but if you are smart you let WordPress doing the job.

Numerous methods for the simple conversion of the code set between pre-and/or code tags are on the web. But there is one for the direct use in WordPress, which takes over to convert the characters perfectly since WordPress 2.8.

//PHP-Code for functions.php

function pre_esc_html($content) {
  return preg_replace_callback(
    '#(<pre.*?>)(.*?)(</pre>)#imsu',
    create_function(
      '$i',
      'return $i[1].esc_html($i[2]).$i[3];'
    ),
    $content
  );
}

add_filter(
  'the_content',
  'pre_esc_html'
);
