Re: Invalidating a form field in cake3 manually

Thanks to jose_zap from IRC, I have found the solution for my issue.

The solution is somewhat similar to http://book.cakephp.org/3.0/en/core-libraries/form.html
In the form subclass, you need this:
public function errors() {
    //return errors in this format:
    //["fieldName" => ["validatorName" => "The error message to display"]]
    return $this->_errors;
}
//You might want to use this class to pass error message
public function setErrors($errors) {
    $this->_errors = $errors;
}

In your controller actions, you would probably do something like this:
$contact = new ContactForm();
$contact->setErrors(["email" => ["_required" => "Your email is required"]]);

Now, you can individually invalidate any form fields from the controller, without a model and the validator class.

 Hi,

I'm relatively new to Cake3.
I have a situation where I have a modelless form that submits data to another server for validation. When I receive the validation errors from the server, I need to be able to invalidate the Form Inputs based on the feedback from the server.
How do I best handle such a situation?
