What you need to do (as we discussed in comments) is run your conditional logic inside the function that that add_action calls. For example, you’re adding an action to the admin notices hook. The action will run, but the stuff inside that action’s callback will only run if you let it. add_action( ‘admin_notices’, ‘your_custom_function’ ); … Read more
add_action( ‘add_meta_boxes_page’, ‘wpse_57924_remove_editor’ ); function wpse_57924_remove_editor( $post ) { if ( $post->ID == get_option( ‘page_on_front’ ) /* or hardcode ID if not front page */ ) remove_post_type_support( ‘page’, ‘editor’ ); }
Use a class, store the value you need in the footer in a member variable. Sample code, not tested: add_shortcode( ‘tooltip’, array ( ‘WPSE_69605_Tooltip’, ‘shortcode_callback’ ) ); class WPSE_69605_Tooltip { protected static $var=””; public static function shortcode_callback( $atts, $content=”” ) { self::$var=”foo”; add_action( ‘wp_footer’, array ( __CLASS__, ‘footer’ ) ); } public static function footer() … Read more
You have nothing specific to do to “load” modified php code in WordPress. All files are just loaded as is at execution time (ie when the HTTP request is processed by the server). You just have to verify that your plugin is active. Your curl command is malformed. Use this instead : curl -X POST … Read more
http://adambrown.info/p/wp_hooks/hook/wp_update_nav_menu?version=3.5&file=wp-includes/nav-menu.php : do_action( ‘wp_update_nav_menu’, $menu_id, $menu_data ); Consequently, a nav menu is a custom post type, as are its menu items, so all of the usual hooks for publish/save/update/trash apply
To clean up a complete array use the helper function __return_empty_array() as callback: add_filter( ‘woocommerce_screen_ids’, ‘__return_empty_array’, ); Similar helpers for further usage are: __return_true() __return_false() __return_zero() __return_null()
You got parentheses levels slightly wrong and that broke your callbacks. It should be: add_action( ‘wp_enqueue_scripts’, array( __CLASS__, ‘frontend_enqueues’ ), 1 );
Well, it’s a little bit complicated 😉 If you will search update_comment_meta hook, you won’t find it. But it exists 🙂 There is update_comment_meta function and it calls update_metadata function with first param set to comment. This update_metadata function does something like this (meta.php line 149): do_action( “update_{$meta_type}_meta”, $meta_id, $object_id, $meta_key, $_meta_value ); where $meta_type … Read more
You could do this by adding a notice, they appear in that spot. Something like this would add a notice just for pages. You would obviously need to adjust the if statement for your CPT and to show on what pages you want. function my_admin_notice() { global $pagenow; if (( $pagenow == ‘edit.php’ ) && … Read more
An action can be removed in time that pass since it is added to it is fired. So after is added, before is fired. You say the plugin has thiss code: add_action(‘wp_enqueue_scripts’, ‘poll_scripts’); function poll_scripts() { // code } But you don’t say if this code is inside a function hooked somewhere. If it is … Read more
