CakePHP 3.x
我想做我的验证码自定义验证.但我无法访问会话.
$validator->notEmpty('securityCode',__('not empty message'))
->add('securityCode','custom',['rule' => function ($value,$context) use ($extra) {
if($this->request->Session()->read('captcha') != $value) {
return false;
}
return true;
},'message' => 'error security code']);
return $validator;
public function validationLogin(Validator $validator,$customParameter)
{ //bla bla }
我用的是：http://book.cakephp.org/3.0/en/core-libraries/validation.html#custom-validation-rules
您可以将Session数据作为验证函数的参数传递
原文链接：https://www.f2er.com/php/137937.html// In Controller
$sessionData = $this->request->Session()->read('captcha');
$validator = $this->{YourModel}->validationLogin(new Validator(),$sessionData);
$errors = $validator->errors($this->request->data());
if (!empty($errors)) {
// Captcha validation Failed
}
// In Model
public function validationLogin(Validator $validator,$sessionData)
{
$validator
->notEmpty('securityCode',__('not empty message'))
->add('securityCode',[
'rule' => function ($value,$context) use ($sessionData) {
if ($sessionData != $value){
return false;
}
return true;
},'message' => 'error securty code'
]);
return $validator;
}
编辑：你可以从模型访问会话,但这不是一个好习惯,你最好避免它.而是将其从控制器传递,如上例所示
// In model
use Cake\Network\Session;
$session = new Session();
$sessionData = $session->read('captcha');
