Wherever you have code you don?t want the visual editor to touch use the [ignore_code] shortcode. 
This version also supports the [insert_php] and <?php tags, though for the PHP tag you will have to 
start the first line with <?php // > With latter two codes you will have to separately install 
plugins to get the dynamic PHP insertion functionality.

Ignore Code

I am using WordPress 6.1. My shortcodes are not ignored within the block editor with this plugin.

Nice idea but does not work

Causes the visual editor to ignore code within the ignore_code shortcode.  Great at keeping advanced HTML, JavaScript, or PHP code intact.
