Wordpress;如何从插件中删除_action以隐藏另一个插件创建的admin_notices

Question

I am a beginner to WP hooks, (actions and filters) I was able to create a Plugin that shows all 4 admin notices in WP dashboard

here the Plugin-one code

    /* Start admin notices on */
  
function display_admin_notice() {
    ?>
    <div class ="notice notice-success is-dismissible"><p>Congratulatios! it seems you have a nice success notice</p></div>
    <div class = "notice notice-error"><p>What a nice error message</p> </div>
    <div class = "notice notice-warning"><p>WARNING!!! site about to blow up in pieces</p></div>
    <div class = "notice notice-info is-dismissible"><p>INFO - you must renew license</p></div>

    <?php
  }
  add_action( 'admin_notices', 'display_admin_notice' );
  
/* Stop admin notices on */

it works perfectly.

Now I have another plugin that hides ALL notifications

/* Start Block ALL admin notices */

add_action('admin_enqueue_scripts', 'block_dismissable_admin_notices');
add_action('login_enqueue_scripts', 'block_dismissable_admin_notices');

function block_dismissable_admin_notices() {
   echo '<style>.wp-core-ui .notice{ display: none !important; }</style>';
}

/* Stop Block ALL admin notices */

it works fine too

BUT I need to REMOVE the action from the first Plugin, NOT to hide all notifications, I mean, is there a way to get the

add_action( 'admin_notices', 'display_admin_notice'

from the first Plugin and remove_action so the Plugin hides/block ONLY the admin_notices from THAT plugin and NOT from all the Wordpress core or another plugins?

Thanks in advance

Answer 1

Instead of loading code and then unloading it (pointless) you could add an if statement to conditionally check if the action hook is needed.

eg.

$noticesOn = true; // Conditional setting could be here

if ( $noticesOn == true ) {
    add_action('admin_enqueue_scripts', 'block_dismissable_admin_notices');
    add_action('login_enqueue_scripts', 'block_dismissable_admin_notices');
}

Answer 2

ok, I finally got it

this is the solution

add_action( 'init', 'remove_my_action' );
function remove_my_action()
{
global $wp_filter;
remove_action( 'admin_notices', 'display_admin_notice');
}

it works perfect
