how to test if form is post or get?

how will i do this? i have the code:

 public function executeListmatches(sfWebRequest $request)
{
    $form_values = $request->getParameter('match_form', array());   
    if (isset($HTTP_P开发者_JAVA技巧OST_VARS))
    {
        $gender_id = $form_values['gender_id2'];
        $age1 = $form_values['age1'];
        $age2 = $form_values['age2'];
        $province_id = $form_values['id'];
    }
    else
    {
        echo $gender_id =  $request->getParameter('gender2');
        echo $age1 =  $request->getParameter('age1');
        echo $age2 =  $request->getParameter('age2');
        echo $province_id =  $request->getParameter('id');
    }
    $this->pager = $this->setupPager($gender_id,$age1,$age2,$province_id);  
    return sfView::SUCCESS;
}     

but the line if (isset($HTTP_POST_VARS)) is not correct thank you

You can check the method with sfWebRequest::isMethod($name);.

So use: if ($request->isMethod('POST')).

HTTP_POST_VARS & HTTP_GET_VARS are both deprecated. Your first condition is usisng POST data
