use getvar for both upper case and lower case

Question

I have this code which i use now:

function onAfterInitialise(){
    $this->username = JRequest::getVar('user', null);
    $this->password = JRequest::getVar('passw', null);

    if(empty($this->username) || empty($this->password))  return true;

    $result = $this->params->get('authmethod','1') === '0' ? $this->plainLogin() : $this->encryptLogin();

    $redirectURL = $this->params->get('urlredirect', null);
    if(!empty($redirectURL)){
        if(!JError::isError($result)){
            $app = JFactory::getApplication();
            $app->redirect($redirectURL);
        }
    }
}

I want it to get the var even if it is user or USER and also for passw or PASSW .

How to do it?

Thanks

Answer 1

The second parameter is the default value and its default value is null . So as long as there are only 2 options - and not stuff like User as well - you can simply do:

$this->username = JRequest::getVar('user', JRequest::getVar('USER'));
$this->password = JRequest::getVar('passw', JRequest::getVar('PASSWD'));

Answer 2

Add some additional checks to the code:

$this->username = JRequest::getVar('user', null);
if (empty($this->username)) {
    $this->username = JRequest::getVar('USER', null);
}

$this->password = JRequest::getVar('passw', null);
if (empty($this->password)) {
    $this->password= JRequest::getVar('PASSW', null);
}

// And then proceed as in your code
if(empty($this->username) || empty($this->password))  return true;
