There are essentially two ways to do this. The first is to supply the taxonomies keyword in the register_post_type arguments array, like so: register_post_type(‘my_type’, array( … ‘taxonomies’ => array(‘category’, ‘post_tag’), … )); The other is to register your post type and set up its taxonomies at a later point: register_taxonomy_for_object_type( ‘category’, ‘my_type’ ); register_taxonomy_for_object_type( ‘post_tag’, … Read more
Use delete_post_meta to delete a value. Example: delete_post_meta($post->ID, ‘brk_news_update’); If you want to update it, then use update_post_meta update_post_meta($post->ID, ‘brk_news_update’,’value’);
Never mind I just went full potato and forgot to include the file into my functions.php Is there any way to delete this question?
You shouldn’t ever be modifying any of the WordPress core files, your changes will be lost as soon as the next WordPress update is released. The easiest way to do this would be with Advanced Custom Fields, create a “relationship” custom field type and make it a required field. That way the user can’t save … Read more

I’m not sure if select multiple value from the select box is what you want, but from a quick look at you code i would say you should put <select name=”‘.$field[‘id’].'[]” id=”‘.$field[‘id’].'”> instead of <select name=”‘.$field[‘id’].'” id=”‘.$field[‘id’].'”> since you want a multiple select. This is then a html problem, not a WP related.
Your problem is you have: foreach post where A is true, that has a child where B is true Which is actually: foreach post where A is true that has a child where B is true So this is not something you should be doing in 1 query. Instead you would need to do n … Read more
You don’t appear to be setting meta_box_nonce anywhere in your code. As your cd_meta_box_save function returns if the nonce isn’t set, your fields will not be saved. See the codex for more on nonces.
To add a meta box to multiple post types, one add_meta_box per post type is needed. In this example, instead of duplicating the same code, a foreach is used. More post types can be added to the array and the meta box will be added in all of them: add_action( ‘add_meta_boxes’, ‘add_custom_box_wpse_94701’ ); function add_custom_box_wpse_94701() … Read more
