filters – How to show ACF fields in Gridbuilder custom block


I’m using GridBuilder WP (great plugin, average support) to show a grid of a custom post type. Ultimately, I need to show an ACF taxonomy field, and their support have recommended using one of their nifty Custom Blocks, but at the moment I’m struggling to just show a text field (as a test) in a Custom Block. This is the suggested code, but it always shows the label “Email” with an empty field, even though there is a normal block above showing the custom field successfully.

    function( $blocks ) {

        $blocks['email_block'] = [
            'name'            => __( 'Email block', 'text-domain' ),
            'render_callback' => function() {

                // Get email from ACF field.
                global $post;
                $post = wpgb_get_post();
                setup_postdata( $post );
                $email = get_field('email');

                if( $email ) {
                        '<a href="mailto:%1$s" rel="external noopener noreferrer" target="_blank">%2$s</a>',
                        esc_attr( rawurlencode( $email ) ),
                        esc_html( 'Email' )


        return $blocks;


Has anyone managed to show custom fields in a Gridbuilder WP custom block?
