cakePHP: how set error validation to input field manually in controller

Question

I want set error validation to input field manually in controller example:

  if ($remainTime < 30) {
      ..... set error validation in here (error: limitTime ), ( error is not in model )
  }

other question: i want to ask : bindModel ( in this case , I use bindModel in Behaviors ) 'll cause loss of relationship with other model but is bindModel cause loss of $var validate,too ?

Solution 1

if the $validate is defined in the model, bindModel wont cause closs of $var validate.

As for you primary question; you can set/unset/update $validationErrors of the models..eg

($remainTime < 30) {
   $this->Model->validationErrors['limitTime'] = "time is less than 30";
}

Solution 2

This can be achieved using the invalidate method that will flag the field as having an error:-

$this->Model->invalidate('field_name', 'error message');

Solution 3

If you want to invalidate an associated model, you can use something like this:

$this->Model1->Model2->invalidate('Model2', __("Your validation message"));

In my case it invalidates associated select multiple (HABTM) field.

no, i want set error validation , in this case, $validate == null

Do you want to invalidate a field, or just to show that the form in general is invalid?

This is probably the more correct answer as this calls the Validator method that does almost the same thing as the currently accepted answer. See the 2.6 API docs here: api.cakephp.org/2.6/source-class-ModelValidator.html#278-288

@neobie this is the correct way of invalidating a field in CakePHP 2.x. If this isn't working for you, you are probably doing something else wrong.

Please note that standard validators reset validation messages so invalidate() results are destroyed if you perform further validations.
