if (function_exists('oxygen_vsb_register_condition')) {
global $oxy_condition_operators;
// Condition to check if a URL parameter is present.
oxygen_vsb_register_condition('URL Param Exists', array('options' => array(), 'custom' => true), array('--'), 'oxy_url_param_exists_callback', 'Other');
function oxy_url_param_exists_callback($value, $operator)
{
if ($_GET[$value]) {
return true;
} else {
return false;
}
}
}
});
