我将向控制器添加什么以显示消息并在验证为真之前停止保存？
class Rsvp extends AppModel {
var $name = 'Rsvp';
var $validate = array(
'uname' => array(
'rule' => array('alphaNumeric', true),
'message' => 'Please enter a vlaid name that does not contain digits'),
'uemail' => array(
'rule' => array('email', true),
'message' => 'Please supply a valid email address.')
);
}
控制器
public function add() {
if ($this->request->is('post')) {
var_dump($this->request->data);
$this->Rsvp->set('uname', $this->request->data['Post']['name']);
$this->Rsvp->set('uemail', $this->request->data['Post']['emailaddress']);
//Begin Validation Routine
echo 'Validation';
var_dump($this->Rsvp->validates);
$this->Rsvp->save();
/*if($this->Rsvp->save()) {
$this->Session->setFlash('You have RSVP for the event');
// $this->redirect(array('action' => 'index'));
}
else {
$this->Session->setFlash('Unable to RSVP you for the event.');
}*/
}
}
你的意思是：
if($this->Rsvp->validates()) {
//data validated, so save
$this->Rsvp->save($this->data);
}
else {
$this->Session->setFlash(__('Fill in all required fields.', true));
}
默认情况下，Model::save() 方法将自动验证。因此，只需尝试保存即可完成验证：
if ($this->request->is('post')) {
if ($this->Rsvp->save($this->request->data)) {
// validated and saved to db
} else {
// didn't validate or failed saving to db
}
}
如果您不想验证，请使用
$this->Rsvp->save($this->request->data, array('validate' => false));
最后，您可以通过设置数据并运行 validates() 方法手动验证。
$this->Rsvp->set('uname', $this->request->data['Post']['name']);
$this->Rsvp->set('uemail', $this->request->data['Post']['emailaddress']);
$validates = $this->Rsvp->validates();
如果未验证，它将设置$this->Rsvp->validationErrors，然后在控制器上设置它，表单帮助程序将意识到这些错误并自动为您显示它们。
