Every post / page / post type is wrapped around a universal form with the ID of #post. So if you want to validate a page before submitting it you just need to say something like: jQuery(document).ready(function($){ $(‘#post’).submit(function(){ // Validate Stuff return false; }); }); Then you’ll want to actually enqueue your javascript – View … Read more
If you want to allow users to “manipulate it before it gets sent off to the API” I would suggest using a filter instead of an action. if ( ! empty( $p[‘form_data’] ) ) { parse_str( $p[‘form_data’], $fd ); if ( ! empty( $fd[‘list-id’] ) ) { // Create and store the variables needed to … Read more
The emailer::send is the function callback for a publish_post action hook. This action hook accepts only one parameter which is the post ID and it is passed by WordPress. When you define an action hook, you set what parameters are passed to the callback functions. For example: $arg_1 = “The aregument value”; do_action( ‘my_custom_action’, $arg_1 … Read more
This problem can be met when hooking in whatever hook that has already been triggered by a precedent do_action (ie. when this_hook has already been mentionned in a do_action within the core files of wordpress or within whatever plugin files) In that particular case, demanding arguments when registering a new function within an add_action(‘this_hook’,’function’, $priority, … Read more
The save_post hook is the only one you need, also, your callback function is missing a parameter, check this example: /** * Save post metadata when a post is saved. * * @param int $post_id The ID of the post. */ function save_book_meta( $post_id ) { /* * In production code, $slug should be set … Read more
WordPress had a built-in conditional tag for that: if ( is_page_template( ‘page-courses.php’ ) ) { include_once(‘functions_courses.php’); }; More infos on the codex
get_nav_menu_locations will give you menu IDs keyed by location which should correspond to the $id also passed with wp_update_nav_menu. add_action(‘wp_update_nav_menu’, function ($id, $data = NULL){ foreach( get_nav_menu_locations() as $location => $menu_id ){ if( $id == $menu_id ){ echo ‘location is ‘ . $location; } } }, 10, 2);
I found my solution. The function you hook into delete_post (or probably any other similar hook) executes as many times as needed. Considering delete_post needs to delete the post and all of its revisions, it will always run more than once. In order to avoid having your function execute each time WordPress deletes a record … Read more
My guess would be that you are remove the action before it is actually being added in the parent theme. The parent’s theme functions.php file gets loaded after the child one so it looks like your removing something that is not there yet. The 3rd parameter in remove_action() is the priority. Try playing around with … Read more
You will have to use wp_footer action for that. And check your pages in functions itself to perform some specific tasks. something like this. function my_footer_function() { if ( is_page( 1032 ) ) { // Do this } elseif ( is_page( 1033 ) ) { // Do that } else { // Do something else … Read more
