CakePHP登录不起作用

Question

My Login Form does Show up, but when I click on my Login Button, nothing happens. I just land onto my Login form again and again. $this->request->data Returns an empty Array.

$this->Auth->data Returns NULL

This is my View (login.ctp):

<?php 
if($this->Session->check('Message.auth')) $this->Session->flash('auth');  
echo $this->Form->create('Veranstalter', array('action' => 'login','url'=>'/veranstalter/login','method'=>'post')); 
?>
<h2>
    Login
</h2>
<table class="input">
    <colgroup>
        <col width="15">
        <col width="75">
    </colgroup>
    <tr>
        <th>
            Veranstalter Nummer
        </th>

        <td>
            <?php echo $this->Form->input('ID',array('type'=>'text','label'=>false)); ?>
        </td>
    </tr>
    <tr>
        <th>
            Passwort
        <td>
            <?php echo $this->Form->input('Passwort',array('label'=>false)); ?>
        </td>
    </tr>
    <tr>
        <th>
            Login
        </th>
        <th>
            <?php echo $this->Form->end('Login');?>
        </th>
    </tr>
</table>

This is my Controller:

    function edit($id = null) {

        $this->Veranstalter->id = $id;

            $this->data = $this->Veranstalter->read();
        } else {

                $this->Session->setFlash('Der Antrag wurde gespeichert');
                $this->redirect(array('action' => 'index'));
            }
        }
    }

    function delete($id = null) {
        $this->Veranstalter->delete($id, false);
        $this->redirect(array('action' => 'index'));
    }

    function logout() {

        $this->redirect($this->Auth->logout());
    }

}

?>

Most tutorials don't explain how the Login works. It just magically happens in the tutorials. My cakePHP Book doesn't implement a login() function at all, it stays empty.

I'm using CakePHP 2.7.

Answer 1

you have passed data in the

$this->Auth->login($this->request->data)

It must be a blank. like below:

$this->Auth->login();
