Here is the code in short that is coming from a plugin:

class Post_Views_Counter_Columns {
     public function __construct() {
        add_action( 'wp', array( $this, 'admin_bar_maybe_add_style' ) );

I want to remove this admin_bar_maybe_add_style function. I am trying with following code in my child theme's functions.php

remove_action( 'wp', array( 'Post_Views_Counter_Columns', 'admin_bar_maybe_add_style' ) );

It's not working. Any suggestions?

  • Is that class coming from a plugin, or where does it inherit from?

  • @WPTricksDK it's coming from a plugin. Sorry I didn't mention that. Aug 5, 2021 at 12:10
  • Please take a look at this thread: stackoverflow.com/questions/36639146/… Don't know if you've tried this already or not - but it's worth a shot.

    I hate this type of classes, in order to remove the action you need to create a instance of that class, when creating an instance the action is called... so anoying. See Removing action added from constructor Aug 5, 2021 at 14:03

I don't understand any of it but it seems to work just fine. Thank you @Buttered_Toast for mentioning the useful thread.

add_action("init", function() {
    global $wp_filter;
    foreach($wp_filter["wp"][10] as $id => $filter) {
    if(is_array($filter["function"]) && count($filter["function"]) == 2 &&
        get_class($filter["function"][0]) == "Post_Views_Counter_Columns" &&
        $filter["function"][1] == "admin_bar_maybe_add_style") {
            remove_action("wp", $id);
}, 99);
