This simple plugin was created because of security concerns related to using PHP preg_replace directly. With transition to PHP7, it’s advised to use preg_replace_callback instead.
This plugin uses built-in supported feature of PHP-“highlight_string”. This plugin filters post content inside custom html block for
<pre> </pre>
and helps display html and other source code.
To display source code in your posts, surround source code with pre tags. Plugin will filter for pre tags and add inline styles that may be modified using your wordpress theme’s css stylesheet.
For WordPress versions 5.0 and above, HTML pre tags can be used within html block or, classic block. Use the three dot menu to convert to html when there is a invalid content error while post editing.
