arrays - Joomla 3.1 getUserStateFromRequest，它会返回一个数组吗？

Question

简短而甜蜜 - 可以getUserStateFromRequest返回一个数组吗？API 文档似乎不完整？

非常感谢！

Answer 1

如果 Joomla 文档仍然非常有限，但在 Joomla 2.5 中查看 JApplication:: 的来源

public function getUserStateFromRequest($key, $request, $default = null, $type = 'none')
{
    $cur_state = $this->getUserState($key, $default);
    $new_state = JRequest::getVar($request, null, 'default', $type);

    // Save the new value only if it was set in this request.
    if ($new_state !== null)
    {
        $this->setUserState($key, $new_state);
    }
    else
    {
        $new_state = $cur_state;
    }

    return $new_state;
}

答案是肯定的，如果你设置它可以

JRequest::setVar('var1', array(1,2,3), 'default');

JFactory::getApplication->setUserState('var1', array(123));

或者只是将它与请求一起传递

$_GET['var1'] = array(1,2,3);
$_POST['var1'] = array(1,2,3);
