You should use register_meta to add the meta field to the rest controller. Here the example from the link to expose the field my_meta of the custom post type my_article: register_meta(‘post’, ‘my_meta’, [ ‘object_subtype’ => ‘my_article’, ‘show_in_rest’ => true ]);
Here is what i have did as a workaround, i realized we cant do that in TDD way.so its better to write the code first instead of writing the test when you face this problem. So in my code i have added this add_meta_box( ‘meta-box-id’, __( ‘My Meta Box’, ‘textdomain’ ), ‘wpdocs_my_display_callback’, ‘post’ ); and … Read more
If the meta field starts with an underscore, it will be hidden in the interface by adding the class hidden to the <tr> element. You could also apply this class by yourself using Javascript, the <tr> element has an id of meta-{$custom_field_id}.
The callback for a meta box gets the current object (post, comment, link, … depending on what you’re editing) passed as the first parameter. So in your meta box handler you can read this first argument and access it’s post_content to get the content.
You want the easy way? Install the More Fields plugin and create your custom field using that. One of the field types is a datepicker: select that when creating the custom field and you’ve got a datepicker.

Apologies for the delay – what I did was basically created a .js file and places it within my theme folder – for example themes/nameoftheme/custom/checkcode.js Then using jquery – I created my code – here’s a snippet: jQuery(‘#in-category-6’).click(function(){ jQuery(‘#metabox_one’).toggle(this.checked); jQuery(‘#metabox_two’).hide(); jQuery(‘#metabox_three’).hide(); jQuery(‘#in-category-3’).attr(‘checked’, this.checked); jQuery(‘#in-category-1’).attr(‘checked’, false); jQuery(‘#in-category-4’).attr(‘checked’, false); jQuery(‘#in-category-5’).attr(‘checked’, false); jQuery(‘#in-category-7’).attr(‘checked’, false); jQuery(‘#in-category-8’).attr(‘checked’, false); jQuery(‘#in-category-9’).attr(‘checked’, false) … Read more
would this be heading in the right direction?.. See Mikes Code
You can create as many metaboxes as you want. Use a function to create them then hook into init. The first line should be $meta_boxes = array(); then start each new metabox with $meta_boxes[] = array( add_action( ‘init’, ‘prefix_create_metaboxes’ ); function prefix_create_metaboxes() { $meta_boxes = array(); $meta_boxes[] = array( ‘id’ => ‘venue_location’, ‘title’ => ‘Venue/Location’, … Read more
Try using media_handle_upload() instead, solved a similar problem for me.
NOTE: It’s kind of late, so the code might not be perfect, but it should get you on the right track. Well, you could theoretically just set up a custom taxonomy and then the user can just use the text box at the bottom and then the check boxes in the Taxonomy selection area. I’ll … Read more
