@degie.

how can i change a default value for a checkbox field?

if (is_user_logged_in()) {
	add_filter( 'ninja_forms_render_default_value', 'loadProfile' , 10 , 3);
	function loadProfile( $default_value, $field_type, $field_settings ) {
            //other code
	    if('allow_marketing' == $field_settings[ 'key' ]) {
	        $default_value = 'checked';
	    }

	  return $default_value;
	}
}

this is not working :(

Where to place this code? I can't find any documentation of it and its so confusing
