It is possible show in a form the error messages with no model associated?
Obviously using the Form helper.
I see validating-data
<http://book.cakephp.org/3.0/en/core-libraries/validation.html#validating-data>,
but I need some guidance about the feasibility automatically display errors
like when work with a model
//view
<?=
$this->Form->create(),
$this->Form->input('name', ['label' => __('Name')]),
$this->Form->input('email', ['label' => __('Email')]),
$this->Form->input('subject', ['label' => __('Subject')]),
$this->Form->input('message', ['label' => __('Message'), 'type' =>
'textarea', 'rows' => '3']),
$this->Form->button(__('Submit')),
$this->Form->end()
?>
//controller
public function contact() {
if ($this->request->is('post')) {
$validator = new Validator();
$validator
->validatePresence('email')
->notEmpty('email', __('This field is required.'))
->add('email', 'valid', ['rule' => 'email', 'message' =>
__('This field requires a valid email address.')])
->validatePresence('name')
->notEmpty('name', __('This field is required.'))
->validatePresence('subject')
->notEmpty('subject', __('This field is required.'))
->validatePresence('message')
->notEmpty('message', __('This field is required.'))
;
$errors = $validator->errors($this->request->data);
if (empty($errors)) {
$this->Flash->success(__('Your data has been sent
succesfully.'));
} else {
$this->Flash->error(__('Unable to sent your data.'));
}
}
}
best regards
