See Why does save_post action fire when creating a new post? You’re getting the error as you need to check for the existence of $_POST[‘xxx’], rather than just checking if $_POST is set (it will always be set & an empty array by default). add_action(‘save_post’, function($id) { if ( ( defined(‘DOING_AUTOSAVE’) && DOING_AUTOSAVE ) || … Read more
Unfortunately, it’s not possible to remove it like a metabox, since it isn’t one. However, there’s a very easy way to get rid of it for a custom post type. If you don’t define anything for the ‘supports’ argument in the registration function, your post type will default to ‘supports’ => array( ‘title’, ‘editor’ ), … Read more
To get the posts from a post type you can use get_posts() $posts = get_posts( array ( ‘numberposts’ => -1, ‘posts_per_page’ => -1, ‘post_type’ => ‘store’ ) ); Be aware, the -1 is dangerous: If there are millions of stores, the query might run into a time-out. Here is a very basic example for such … Read more

After doing some more research I found that: Instead of hooking the add_meta_box function into admin_menu it should be hooked into add_meta_boxes Instead of the foreach loop use the update_post_meta function on the save function Instead of using the wp_nonce_field the data can be sanitized using esc_attr and strip_tags To pass the post id to … Read more
After too many tries i have found following solution myself, but this could save others time. $pid = (isset($_GET[‘post’]) ? $_GET[‘post’] : $_POST[‘post_ID’]); $page_att = get_page( $pid ); $page_parent = $page_att->post_parent; if(15 == $page_parent){ //register metabox }
You need to call do_meta_boxes() in your plugin options page and not in the admin_init hook.
Basically you need to add the html of the select dropdown at your function inventory_information() which is the function that actually displays the metabox: // The Event Location Metabox function inventory_information() { global $post; // Noncename needed to verify where the data originated echo ‘<input type=”hidden” name=”inventorymeta_noncename” id=”inventorymeta_noncename” value=”‘ . wp_create_nonce( plugin_basename(__FILE__) ) . ‘” … Read more

Here are couple use cases that will hopefully give you a better idea on how to proceed: If you want to verify that the url’s domain is … Read more
