    class loginform extends form     {             public function __construct($name = null)             {                 parent::__construct('login');                 $this->setattribute('method', 'post');                 $this->add(array('name'=>'uname','attributes'=>array('type'=>'text',),                     'options'=>array('label'=>'username'),                 ));                  $this->add(array('name'=>'pword','attributes'=>array('type'=>'password',),                     'options'=>array('label'=>'password'),                 ));                  $this->add(array('name'=>'submit','attribute'=>array('type'=>'submit',                     'value' => 'go',                 'class'=>'submit','id'=>'submitbutton',)                   ));             }     } 

below code login page

$form = $this->form; $form->setattribute('action', $this->url('users', array('action' => 'login'))); $form->prepare();  echo $this->form()->opentag($form); echo $this->formrow($form->get('uname')); echo $this->formrow($form->get('pword')); echo $this->formelementerrors($form->get('pword'));  echo $this->formsubmit($form->get('submit'));  echo $this->form()->closetag(); 

form works fine no issues :

1. it not taking value submit if see viewsource shows value=''
2. i want display error message ever wish how achive that? tried echo $this->formelementerrors($form->getmessages('uname')); did not work suggestion or ideas fix this?

below controller code...

$form = new loginform(); $request = $this->getrequest();  if ($request->ispost()) {     $post = $request->getpost();     if($post->get('uname')=='')     {         $umessage='please enter username';         return $this->redirect()->toroute('users',array('action'=>'login'));     }      $this->db =$this->getservicelocator()->get('db');     $authadapter = new authadapter($this->db);     $authadapter->settablename('users')         ->setidentitycolumn('uname')         ->setcredentialcolumn('pword');      $authadapter->setidentity($post->get('uname'))         ->setcredential(md5($post->get('pword')));      $authservice = new authenticationservice();     $authservice->setadapter($authadapter);      $result = $authservice->authenticate();      if ($result->isvalid()) {         return $this->redirect()->toroute('users');     } else {         switch ($result->getcode()) {             case result::failure_identity_not_found:                 echo 'user name not valid dude';                 break;              case result::failure_credential_invalid:                 echo 'password incorrect';                 break;              case result::success:                 echo 'login successfull';                 break;         }      } } $this->layout('layout/index'); return array('form' => $form); 

you syntax incorrect displaying individual error messages, try this:

change:

$this->formelementerrors($form->getmessages('uname')); // incorrect $this->formelementerrors($form->get('uname')); // correct 

example:

<?php foreach($form->getelements() $element): ?>     <?php if($element->getlabel()): ?>         <?php echo $this->formlabel($element) ?>     <?php endif ?>     <?php echo $this->formelementerrors($element, array('class' => 'inline')); ?>    <?php echo $this->formelement($element) ?> <?php endforeach ?> 

notice passing in actual element, not via getmessages().

you have type on button definition (missing s on end):

attribute => attributes 

see below:

$this->add(array(      'name'=>'submit',      'attributes' => array(          'type'=>'submit',          'value' => 'go',          'class'=>'submit','id'=>'submitbutton',       )   )); 

i assuming have setup input filters too?

$inputfilter->add($factory->createinput(array(     'name'     => 'username',     'required' => true,     'filters'  => array(         array('name' => 'striptags'),         array('name' => 'stringtrim'),     ),     'validators' => array(         array(             'name'    => 'stringlength',             'options' => array(                 'encoding' => 'utf-8',                 'min'      => 1,                 'max'      => 100,             ),         ),     ), )));
