How to set autoload from "yes" to "no" _transient_wp_core_block_css_files

Question

In WordPress version 6.3, create a transient named "_transient_wp_core_block_css_files" (~0.4MB) in the wp_options table to store the list of CSS files to load when using WordPress' blocks. When the site loads and needs to use the block, WordPress checks this transient to determine if the CSS files need to be loaded.

I don't use the block. I tried to set autoload from "yes" to "no" but failed:

1. I try to change yes to no in phpmyadmin but no success.
2. I try this in funtions.php but no success. add_filter( 'block_styles_should_load', '__return_false' ); delete_transient( '_transient_wp_core_block_css_files' );

Do you know any better way?

Answer 1

Don't bother messing the with autoload on the transient. If you're truly not using blocks at all, just unhook the function that creates the transient and uses it to register the style handles:

remove_action( 'init', 'register_core_block_style_handles', 9 );

Just be aware that if you do use blocks, their stylesheets will not load until you let WordPress create the transient again.

Answer 2

It is work for me.

function remove_core_block_style_handles() {
    remove_action( 'init', 'register_core_block_style_handles', 9 );
}
add_action( 'init', 'remove_core_block_style_handles' );


if ( function_exists( 'delete_transient' ) ) {
    delete_transient( 'wp_core_block_css_files' );
}
