Question

我正在尝试从包含以下代码行的插件类WallpaperManager.getDrawable() -> //Retrieve the current system wallpaper.中删除操作：

WC_GFPA_Entry

这是类代码：

add_action( 'gform_entry_detail_content_before', array( $this, 'entry_detail_screen_notice' ), 10, 2 );

到目前为止我在class WC_GFPA_Entry { private static $instance; public static function register() { if ( self::$instance == null ) { if ( apply_filters( 'woocommerce_gravityforms_create_entries', true ) ) { self::$instance = new WC_GFPA_Entry(); } } } private $_resuming_orders = array(); private function __construct() { add_filter( 'gform_entry_detail_meta_boxes', array( $this, 'add_custom_entry_metabox' ), 10, 3 ); add_action( 'gform_entry_detail_content_before', array( $this, 'entry_detail_screen_notice' ), 10, 2 ); } public function add_custom_entry_metabox( $meta_boxes, $entry, $form ) { // some code } public function entry_detail_screen_notice( $form, $lead ) { // some code ..... } }尝试过的内容：

functions.php

和

remove_action( 'gform_entry_detail_content_before', array( WC_GFPA_Entry::register(), 'entry_detail_screen_notice' ), 10, 2 );

我也试过改变优先级等，但没有真正起作用。任何帮助将不胜感激。

不幸的是，没有简单的方法可以做到这一点。但是，可以通过使用这样的实用程序来实现：

https://github.com/herewithme/wp-filters-extras/blob/master/wp-filters-extras.php

所以在你的例子中会是：

remove_filters_for_anonymous_class('gform_entry_detail_content_before', 'WC_GFPA_Entry', 'entry_detail_screen_notice', 10)

上面的Lib代码：

function remove_filters_with_method_name( $hook_name = '', $method_name = '', $priority = 0 ) {
    global $wp_filter;
    // Take only filters on right hook name and priority
    if ( ! isset( $wp_filter[ $hook_name ][ $priority ] ) || ! is_array( $wp_filter[ $hook_name ][ $priority ] ) ) {
        return false;
    }
    // Loop on filters registered
    foreach ( (array) $wp_filter[ $hook_name ][ $priority ] as $unique_id => $filter_array ) {
        // Test if filter is an array ! (always for class/method)
        if ( isset( $filter_array['function'] ) && is_array( $filter_array['function'] ) ) {
            // Test if object is a class and method is equal to param !
            if ( is_object( $filter_array['function'][0] ) && get_class( $filter_array['function'][0] ) && $filter_array['function'][1] == $method_name ) {
                // Test for WordPress >= 4.7 WP_Hook class (https://make.wordpress.org/core/2016/09/08/wp_hook-next-generation-actions-and-filters/)
                if ( is_a( $wp_filter[ $hook_name ], 'WP_Hook' ) ) {
                    unset( $wp_filter[ $hook_name ]->callbacks[ $priority ][ $unique_id ] );
                } else {
                    unset( $wp_filter[ $hook_name ][ $priority ][ $unique_id ] );
                }
            }
        }
    }
    return false;
}
/**
 * Allow to remove method for an hook when, it's a class method used and class don't have variable, but you know the class name :)
 */
function remove_filters_for_anonymous_class( $hook_name = '', $class_name = '', $method_name = '', $priority = 0 ) {
    global $wp_filter;
    // Take only filters on right hook name and priority
    if ( ! isset( $wp_filter[ $hook_name ][ $priority ] ) || ! is_array( $wp_filter[ $hook_name ][ $priority ] ) ) {
        return false;
    }
    // Loop on filters registered
    foreach ( (array) $wp_filter[ $hook_name ][ $priority ] as $unique_id => $filter_array ) {
        // Test if filter is an array ! (always for class/method)
        if ( isset( $filter_array['function'] ) && is_array( $filter_array['function'] ) ) {
            // Test if object is a class, class and method is equal to param !
            if ( is_object( $filter_array['function'][0] ) && get_class( $filter_array['function'][0] ) && get_class( $filter_array['function'][0] ) == $class_name && $filter_array['function'][1] == $method_name ) {
                // Test for WordPress >= 4.7 WP_Hook class (https://make.wordpress.org/core/2016/09/08/wp_hook-next-generation-actions-and-filters/)
                if ( is_a( $wp_filter[ $hook_name ], 'WP_Hook' ) ) {
                    unset( $wp_filter[ $hook_name ]->callbacks[ $priority ][ $unique_id ] );
                } else {
                    unset( $wp_filter[ $hook_name ][ $priority ][ $unique_id ] );
                }
            }
        }
    }
    return false;
}
