Simple, you’re addressing $post out of context. When you’re running a standard WordPress loop, WP will load a global $post variable with the results of the current query. This includes the ID, title, content, post meta, etc. The loop functions will reference this global variable to actually give you data. Take the regular function get_the_ID() … Read more
Yes there is, from Debugging in WordPress codex, you need to define SCRIPT_DEBUG in wp-config.php to force WP to load the dev versions of the scripts: define(‘SCRIPT_DEBUG’, true);

The post ID is available after the query has been fired. The first hook that is safe to get post id is ‘template_redirect’. If you can modify your function to accept a post id as argument, like so: function em_change_form($id){ $reg_type = filter_input(INPUT_GET, ‘reg_typ’, FILTER_SANITIZE_STRING); if($reg_type === ‘vln’){ update_post_meta($id,’custom_booking_form’, 2); } elseif ($reg_type == ‘rsvp’) … Read more
With get_terms(), the exclude parameter takes an array of term IDs, so just add the second term to the array: $terms = get_terms( TribeEvents::TAXONOMY, array( ‘orderby’ => ‘name’, ‘order’ => ‘ASC’, ‘exclude’ => array( 77, 71 ), ) ); echo ‘<li>Category:</li>’; foreach ( $terms as $term ) { echo ‘<li><a href=”‘.$url.’?tribe_eventcategory=’.$term->term_taxonomy_id.'”>’.$term->name.'</a></li>’; }
Hook into postbox_classes. postbox_classes is the function which will output the classes for the metabox. apply_filters( “postbox_classes_{$page}_{$id}”, $classes ) Your code could look like this: add_action( ‘add_meta_boxes’, ‘add_my_metabox’ ); function add_my_metabox() { $id = ‘my-metabox’; $title=”My Metabox”; $callback = ‘my_metabox_content’; $page=”post”; add_meta_box( $id, $title, $callback, $page ); add_filter( “postbox_classes_{$page}_{$id}”, ‘minify_my_metabox’ ); } function my_metabox_content() { … Read more
See this related question. I guess in your case you’d wrap your code in if( $args->theme_location == ‘primary-menu’ ).
This function exists in wp-admin/includes/plugin.php so I’m assuming it doesn’t get included by the theme. You can either require it, or just create your own version of it – see here: http://wordpress.org/support/topic/is_plugin_active UPDATED: Please check is_plugin_active
You’ll want to use a custom post type for this. But don’t let the terms “custom post type” scare you off. For example, one of my clients needed to present a “line card” displaying their various partners. All they wanted, originally, was the name and logo of their various partners. After I built out the … Read more
It’s not possible to call a private method through an action or filter. When calling add_action or add_filter, WordPress adds the callback to a list of callbacks for that specific action or filter. Then, when do_action or apply_filters is called, WordPress uses call_user_func_array to call the linked functions and methods. As call_user_func_array is not called … Read more
