Processing WordPress 3rd party plugin admin page HTML

For front facing WP pages I use the the_content filter to pre-process the HTML by using either regex or DOMDocument() in order to, for example, prepare inline images for a lazyload script.

Is there an equivalent filter I can use to alter a plugin's admin page's HTML?

Thank you!

Solution

  • For further reference, there is no equivalent to the_content in regards to a 3rd party plugin's admin page's HTML.

    Plugins output their admin HTML using the custom {$page_hook} action.

    For anybody interested, also take a look at the \wp-admin\admin.php file, the load-{$page_hook} action and the get_plugin_page_hook function.
