CakePHP验证

Question

How do I show the messages when using the CakePHP validation? As I creating the input fields manually using input() instead using the shorthand form() helper.

eg Form:

<?php echo $this->Form->create('User', array('id' => 'loginform', 'type' => 'post',
'url' => array('controller' => 'users', 'action' => 'login'))); ?>

    <fieldset id="login">

        <ul class="clearfix">               
            <li id="li-username">
                <?php echo $this->Form->input('email', array( 'label' => array('class' => 'placeholder', 'text' => 'Email address or username') )); ?>
            </li>
            <li id="li-password">
                <?php echo $this->Form->input('password', array( 'type' => 'password', 'label' => array('class' => 'placeholder', 'text' => 'Password') )); ?>
                <span id="iforgot"><?php echo $this->Html->link('?', 
                array('controller' => 'users', 'action' => 'forgotpassword'),  array('title' => 'Forgot your password?')); ?></span>
            </li>
            <li id="li-submit">
                <button type="submit" title="Log in">Log in &#9658;</button>
            </li>
        </ul>

    </fieldset>

<?php echo $this->Form->end(); ?>

and this is my validation in the user model:

public $validate = array(
    'email' => array(
        'valid' => array(
            'rule' => 'email',
            'message' => 'The email is not valid'
        ),
        'required' => array(
            'rule' => 'notEmpty',
            'message' => 'Please enter an email'
        )
    )
);

However the validation error messages don't show?

EDIT: I tested this on my register form at /users/add/ and it works so it seems that the auto validation does not work with the login method???? How do I add validation for the login form then :/

Answer 1

The validation is actually stored in the model object. I'm not entirely sure off-hand how to access the errors, but I think its in $this->User->validationErrors.

Have a look at the model api for more information.

For logging in, use the auth component . If you'd rather not, then just get the user from the db and display an error using $this->Session->SetFlash() if the user doesn't authenticate.

Answer 2

You can show your code login function?
I think in your code that have redirect in-case validate false
If you use $this->redirect() it'll not show validate messages :)

Answer 3

First you check your post data is going to validate function.you can simple check this in your else condition like this :

$this->{$this->modelClass}->set($this->data);
if($this->{$this->modelClass}->validates(){
    //Save data in DB
}else{
   pr($this->{$this->modelClass}->validationErrors); // This will show your error message
}

You can also show error in your view.ctp file like this

$errors = '';
    foreach ($this->validationErrors[$model] as $key =>  $validationError) { 
        $errors .= $this->Html->tag('li', $validationError[0]);
    }
    echo $this->Html->tag('ul', $errors,array('class' => 'error'));
