Hooks and filters can have several Actions attached. Hence the $priority argument. In short: It’s just a big multi dimensional array where the key is the hook/filter name and the values are the attached callbacks plus their priority.
The plugin add content using the_content filter with a lower priority: 100. So you can create a function that output metafields and use same filter with an higher priority, even the standard 20 priority is good. function my_post_custom_data( $content ) { if ( ! is_single() ) return; global $post; // here go the code that … Read more
You have to say how many parameters your callback function needs. The default is 1, so WordPress will pass just $a. To get more parameters, use the fourth argument for add_action(): add_action(‘test’, ‘testing’, 10, 2 );
This should do. Put the following in your functions.php if (in_array($GLOBALS[‘pagenow’], array(‘edit.php’, ‘post.php’, ‘post-new.php’))) add_filter(‘admin_footer_text’, ‘my_custom_footer_admin_text’); function my_custom_footer_admin_text($text) { $post_type = filter_input(INPUT_GET, ‘post_type’); if (! $post_type) $post_type = get_post_type(filter_input(INPUT_GET, ‘post’)); if (‘my_post_type’ == $post_type) return ‘my custom message’; return $text; }
wp_referer_field is a function. You cannot treat a function like a hook. That isn’t how hooks work. That is, you can’t hook into a function name. Hooks are intentionally created. (And there are no hooks built into that function) Secondly, you can’t override a function at all, as a rule. Some few functions in WordPress … Read more
That’s because object properties are case sensitive, thus $post->ID is not the same as $post->id . Just by printing out these two you’ll notice the difference, or do a print_r of the $post object to see all of the available properties and methods.

The add_submenu_page first parameter should be the top menu page handle which in you case is a-qoute so: function a_qoute_admin_action(){ add_menu_page( __(‘Reservations Pages’),// the page title __(‘Donation’),//menu title ‘edit_themes’,//capability ‘a-qoute’,//menu slug/handle this is what you need!!! ‘qoute_settings’,//callback function ”,//icon_url, ”//position ); add_submenu_page( ‘a-qoute’, ‘Donations Log’, //page title ‘Donations Log’, //menu title ‘edit_themes’, //capability, ‘DonationsLog’,//menu slug … Read more
It’s simply the wrong endpoint. The admin_post_* hook and its admin_post_nopriv_* counterpart is not fired for any admin page with the appropriate action request variable set, it only triggers for requests hitting wp-admin/admin-post.php. Try https://test.local/wp-admin/admin-post.php?action=test instead. I should add that using admin-post.php for handling plugin actions might not be appropriate. If you wanted to return … Read more
There is a dynamic hook right before any new metadata is added: do_action( “add_{$meta_type}_meta”, $object_id, $meta_key, $_meta_value ); It would be add_post_meta for posts accordingly.
