Home Forums Feature Requests Conditional Logic using Taxonomy field Reply To: Conditional Logic using Taxonomy field

  • Hi, I seem to be having a bit of a problem. I used Beee’s code and altered it to fit my taxonomies, but unfortunately it’s not working as wanted.

    I have a custom post type with a taxonomy (‘type’), type can either be ‘movie’ or ‘series’.

    My ACF Radio button field has these choices, the value given is the value of the term:

    2 : Movie
    4 : Series

    This will output the value of the field, not the name or array.

    In my functions.php I have:

    function change_media_type( $post_id ) {
        // bail if no ACF data
        if ( empty($_POST['acf']) ) {
        // get term id from $post_id (only 1 value is allowed, so it returns 1 value only)
        $stored_type = wp_get_post_terms($post_id, 'type');
        // get submitted value from acf form
        $posted_type = $_POST['acf']['field_picktype'];
        // get term_id for the submitted value
        $term_id = get_term_by( 'id', $posted_type, 'type' );
        // if stored value is not equal to posted value, then update terms
        if ( $stored_type != $posted_type ) {
            wp_set_object_terms( $post_id, $term_id->term_id, 'type' );
    add_action('acf/save_post', 'change_media_type', 20);

    But it doesn’t seem to change the taxonomy of the post as I want. It changes, but simply changes to “—”. Could anyone point me in the right direction?
