Validation error not displayed CakePHP - validation

Question

I'm trying to display validation errors with CakePHP (Newbie) but I'm stuck. I get this error "Delimiter must not be alphanumeric or backslash". Don't know if the logic is respected, I'm starting from scratch.
Nothing is displayed. Here's my code:
User model
class User extends AppModel {
public $validate = array(
'nom' => array(
'message' => 'Saisie obligatoire',
'required' => true
),
'prenom' => array(
'message' => 'Saisie obligatoire',
'required' => true
),
'date_naissance' => array(
'rule' => array('date','dmy'),
'message' => 'Veuillez respecter le format de la date (jour/mois/année)',
'allowEmpty' => true
),
'email' => array(
'rule' => 'email',
'message' => 'Veuillez introduire une adresse mail valide',
'required' => true
),
'password' => array(
'rule' => 'password',
'message' => 'Un mot de passe est requis'
)
);
public function beforeSave($options = array()) {
if (isset($this->data[$this->alias]['password'])) {
$this->data[$this->alias]['password'] = AuthComponent::password($this->data[$this->alias]['password']);
}
return true;
}
}
add function into UsersController
public function add() {
if ($this->request->is('post')) {
$this->User->set($this->request->data);
if ($this->User->validates()) {
$this->User->create();
if ($this->User->save($this->request->data)) {
$this->Auth->login($this->User);
return $this->redirect('/index');
}
}
} else {
return $this->User->validationErrors;
}
}
add.ctp
<?= $this->element('navbar');?>
<div class="formcontainer">
<div class="page-header">
<h1>Rejoignez-nous</h1>
</div>
<form action="/users/add" id="UserAddForm" method="post" accept-charset="utf-8">
<div style="display:none;">
<input type="hidden" name="_method" value="POST"/>
</div>
<div class="form-group input text">
<label for="UserNom">Nom:</label>
<input name="data[User][nom]" maxlength="20" type="text" id="UserNom" class="form-control" placeholder="requis">
</div>
<div class="form-group input text">
<label for="UserPrenom">Prénom:</label>
<input name="data[User][prenom]" maxlength="20" type="text" id="UserPrenom" class="form-control" placeholder="requis">

<div class="form-group input text">

<input name="data[User][date_naissance]" maxlength="20" type="text" id="UserDateNaissance" class="form-control">
</div>
<div class="form-group input email">
<label for="UserEmail">Email:</label>
<input name="data[User][email]" maxlength="100" type="email" id="UserEmail" class="form-control" placeholder="requis"/>
</div>
<div class="form-group input password">
<label for="UserPassword">Mot de passe:</label>
<input type="password" name="data[User][password]" class="form-control" id="UserPassword" placeholder="requis">
</div>
<button type="submit" class="btn btn-default bSub">M'inscrire</button>
</form>
</div>

Answer 1

Your validation should be like this(You must add rule for field and there is no inbuilt passowrd rule in cakephp).
public $validate = array(
'nom' => array(
'rule' => 'notEmpty', //add rule here
'message' => 'Saisie obligatoire',
'required' => true
),
'prenom' => array(
'rule' => 'notEmpty', //add rule here
'message' => 'Saisie obligatoire',
'required' => true
),
'date_naissance' => array(
'rule' => array('date', 'dmy'),
'message' => 'Veuillez respecter le format de la date (jour/mois/année)',
'allowEmpty' => true
),
'email' => array(
'rule' => 'email',
'message' => 'Veuillez introduire une adresse mail valide',
'required' => true
),
'password' => array(
'rule' => 'notEmpty', //there is no inbuilt validation rule with name *password*
'message' => 'Un mot de passe est requis'
)
);
If you want to show error message then you should use Form Helper for create form inputs like this
echo $this->Form->input("User.nom", array("class"=>"form-control", "placeholder"=>"requis", 'label'=>false));
Or you can display message by using isFieldError method of Form helper
if ($this->Form->isFieldError('nom')) {
echo $this->Form->error('nom');
}
