Custom Modifiers

Create a custom modifier. This example adds a “filename” modifier that returns the filename of the generated QR code. This code would be activated with a merge tag like so: {My Field:1:qr,filename}.

add_filter( 'gp_qr_code_merge_tag_value', function( $value, $qr_url, $merge_tag_value, $modifiers, $form ) {
    if ( isset( $modifiers['filename'] ) ) {
        $value = pathinfo( $qr_url, PATHINFO_BASENAME );
    return $value;
}, 10, 5 );
