I’ve tried to make appropriate comments in the necessary places for you, though bear in mind i threw this all together for you with a small amount of … Read more
Nevermind, I figured this out. The id needs to be “category_” and then the ID. So the code is: $sub_heading = get_field(“sub_heading”, “category_” . $cat->term_id);
You won’t be really able to tell which context the image is being used in in the wp_get_attachment_image_attributes filter, but you can pass custom attributes to wp_get_attachment_image() in the template directly with the 4th argument. Then you can use wp_get_attachment_image_url() and wp_get_attachment_image_srcset() to get the values for those attributes: $image = get_field(‘image’); $size=”gallery”; echo wp_get_attachment_image( … Read more
See add_meta_box which has a lot of demo code for working with meta fields. Here is the most relevant part for you: /* Do something with the data entered */ add_action( ‘save_post’, ‘myplugin_save_postdata’ ); /* When the post is saved, saves our custom data */ function myplugin_save_postdata( $post_id ) { // First we need to … Read more

This way you don’t have to worry about the rest or the query options as they will still work. It should look like this (untested), and be placed in a plugin or theme functions file (not in … Read more
Something like this should work: function wpa84258_admin_posts_sort_last_name( $query ){ global $pagenow; if( is_admin() && ‘edit.php’ == $pagenow && !isset( $_GET[‘orderby’] ) && !isset( $_GET[‘post_type’] ) ){ $query->set( ‘meta_key’, ‘last_name’ ); $query->set( ‘orderby’, ‘meta_value’ ); $query->set( ‘order’, ‘ASC’ ); } } add_action( ‘pre_get_posts’, ‘wpa84258_admin_posts_sort_last_name’ );
What is the exact meta_key and meta_value for the field I created using the function custom_user_profile_fields ? created_by and some user ID, for example: $args = array( ‘meta_key’ => ‘created_by’, ‘meta_value’ => 123, ) You could use a meta_query for more complex searches. $args = array( ‘meta_query’ => array( array( ‘key’ => ‘created_by’, ‘compare’ => … Read more
Just add an underscore before the metabox ID so the part of your code where you add a metabox looks something like this: $id = ‘_drama-description’; $title=”Description”; $callback = ‘drama_description_metabox_markup’; $screen = $post_type; $context=”normal”; $priority = ‘high’; $callback_args=”null”; add_meta_box($id, $title, $callback, $screen, $context, $priority, $callback_args); You also need to replace every occurance of drama-description to … Read more
