Question

$this->validatorSchema->setPostValidator(new sfValidatorAnd(array(
      new sfValidatorSchemaCompare('email', '==', 'email_confirm',
            array(),
            array('invalid' => 'The email adresses must match')
          ),
      new sfValidatorSchemaCompare('password', '==', 'password_confirm',
            array(),
            array('invalid' => 'The passwords must match')
          ),
        )));

this compare two values from Form.
I would like make compare with own values:

    new sfValidatorSchemaCompare('secret_key', '==', '123456',
            array(),
            array('invalid' => 'The secret key must match')
          ),

            How can i make it?

Answer 1

The sfValidatorSchemaCompare compares the entered value in two fields (like in your first example).
For example: it tests if the password matches the password_confirm values. In this case both the password and password_confirm have to be fields in your form (validators to be exact).

In your case, you want to check if a secret_key matches a predefined value, not another field.
And this is a bit strange, by default symfony doesn’t have a validator to check this. But you can easily use the sfValidatorChoice to achieve your target:

$this->validatorSchema['secret_key'] = new sfValidatorChoice(array('choices' => array('123456')));

In this case the value entered in secret_key is matched against a list of values, which only contains your secret key.

And a little “pro-tip” ;-): Add the secret_key to your app.yml, and then just add sfConfig::get('app_form_secret_key') to test.
