Hello, I'm new to PHP Phalcon. I have a variable called username and I'm developing an Arabic website. so when I check if varaible is empty I use this approach

$this->validate(new PresenceOf(array( 'field' => 'username', 'message' => 'You need to type username' )));

it works when I type English characters but if I type Arabic characters it return error message 'you need to type username'.

how to solve this problem? thanks :)

Are you sure it is exactly "you need to type username"?

Try to include this in your model class in your initialize() method:


class YourModel extends YourOrPhalconBaseModel {

  public function initialize() {

    $this->setup(array(
        'notNullValidations'=>false,
    ));

  }

}

Be carefull because this switch off Phalcon's authomatic PresenceOf validators in this model. It means that if:

you do not set up you own PresenceOf validators for all fields
and you will try to save an entity to DB and one field will be empty

Then exception will be thrown.

I found my mistake, I'm learning using the examples that provided in documentation and I have copied UserController from one of them.

the problem was in this code

$username = $request->getPost('username', 'alphanum');

so I just removed the second parameter and now it works well :)

Thank you and I'm sorry for my very simple mistake.
