    public function loginAction() {
        $obj = new Application_Form_Login();

        $request = $this->getRequest();
        if ($request->isPost()) {
            if ($obj->isValid($request->getPost())) {
                if ($this->_process($obj->getValues())) {
                    $this->_helper->redirector('arcade', 'index');
                }
            }
        }
        $this->view->form=$obj;
    }

Login form =>

 

    <?php
    
    class Application_Form_Login extends Zend_Form
    {
    
        public function init()
        {
    		$this->setName("login");
    		$this->setMethod("post");
    
    		$temp=array(array('StringLength',false,array(0,50)));
    
    		$this->addElement('text','usr',array(
    			'filters'=>array('StringTrim','StringToLower'),
    			'validators'=>$temp,
    			'required'=>true,
    			'label'=>'Username',
    		));
    
    		$this->addElement('password','psw',array(
    			'filters'=>array('StringTrim'),
    			'validator'=>$temp,
    			'required'=>true,
    			'label'=>'Password',
    		));
    
    		$this->addElement('submit','log',array(
    			'required'=>false,
    			'ignore'=>true,
    			'label'=>'Login',
    		));
        }
    
    }

try changing

$temp=array(array('StringLength',false,array(0,50)));

 

to

$temp=array('StringLength',false,array(0,50));

[colap]

try changing

$temp=array(array('StringLength',false,array(0,50)));

 

to

$temp=array('StringLength',false,array(0,50));

 

No, there problem was here =>

 

'validator'=>$temp,
