I’m sure there is a more elegant approach (I’d love to know about!). Anyhow: I’d like to offer a solution. You could create a default sidebar with default widgets and a custom sidebar with all available custom widgets. Then you use a combination of the following plugins: simple fields and widget logic to only show … Read more
It’s informative to check out the /wp-admin/post.php file, that contains the edit_post() function that calls wp_update_post(), which is a wp_insert_post() wrapper. Here’s a skeleton for saving the assigned category terms: /** * Saving assigned category terms (skeleton) */ add_action( ‘admin_action_editpost’, function() { add_filter( ‘wp_insert_post_data’, function( $data, $parr ) { add_action( ‘save_post_post’, function( $post_ID, $post ) … Read more
You cannot use a real metabox to do that, hook into edit_form_after_title instead. Here is a simple example: add_action( ‘edit_form_after_title’, ‘wpse_87478_pseudo_metabox’ ); add_action( ‘save_post’, ‘wpse_87478_save_metabox’ ); function wpse_87478_pseudo_metabox() { global $post; $key = ‘_wpse_87478’; if ( empty ( $post ) || ‘post’ !== get_post_type( $GLOBALS[‘post’] ) ) return; if ( ! $content = get_post_meta( $post->ID, … Read more
The way your code is setup is just wrong, you are making two database calls for each custom field and if you have between 2-30 fields like this then that means you make over 60 calls to the database which can be done with a single call using get_post_custom() for ex: $custom_fields = get_post_custom($post->ID); for … Read more
Define an array of post types, and register the metabox for each one separately: function add_custom_meta_box() { $post_types = array ( ‘post’, ‘page’, ‘event’ ); foreach( $post_types as $post_type ) { add_meta_box( ‘custom_meta_box’, // $id ‘Custom Meta Box’, // $title ‘show_custom_meta_box’, // $callback $post_type, ‘normal’, // $context ‘high’ // $priority ); } }
A meta box is an element in the graphical user interface, a custom field is an extra key and value stored with a post. Most of the time the interface to change the value of a custom field is put in an extra meta box – or in the default meta box for custom fields, … Read more
I’m not 100% clear on what your question is, but hopefully this will cover it: There’s a lot of documentation of how to use AJAX in WP. I would start here: https://codex.wordpress.org/AJAX In the function that you write to hook your AJAX call into, make a call to the DB to see if the user-entered … Read more
Yes, it is possible to limit the drag and drop functionality of your boxes. All one needs to do is find the right selectors for the specific boxes it wants to target. When you use $(“.meta-box-sortables”).[…] you are targeting all elements in the page with the class of meta-box-sortables. If, however, you add a custom … Read more
Users can drag and drop meta boxes and WordPress will save the order. So, in a sense, the order in which they were originally rendered does not matter. You know which one comes first because when you call add_meta_box it simply pushes your meta box’s args onto a global array called $wp_meta_boxes. Whichever call to … Read more
I did something like this once, but when you clicked on a certain category (essentially the same) It certainly isn’t a true ajax solution, it just hides and reveals the div with the settings, but It is a solution which works. You’ll definitely have to modify this for your needs, but if you have a … Read more
