taxonomy field not saving terms for the custom post

Hi Akram,

Did you put the taxonomy field in a group? Only in that case, the taxonomy terms are saved in the group's meta value and don't set the post terms.

Hi Akram,

If you want to set post terms, you have to move the taxonomy field outside the group. You can use Meta Box Conditional Logic to hide the field if you want. If you still need to keep it inside a group, then there's no way to achieve that.

Hi Akram,

Sorry to make you feel like that. What I meant is that's the default behavior of the fields.

You still can change the behavior with the plugin action, like this:

add_action( 'rwmb_after_save_post', function( $post_id ) {
    $group = get_post_meta( $post_id, 'group_id', true );
    $terms = $group['terms'] ?? [];

    wp_set_post_terms( $post_id, $terms, 'your_taxonomy' );
} );
