How to display Variable in Error Messages during Data Validation?

0DownUp

Hi,

Anyone know how to display Variable in Error Messages during Data Validation?

for example, for the code below in MODEL


var $validate = array(
    'login' => array(
        'rule' => 'alphaNumeric',
        'message' => 'Usernames must only contain letters and numbers.'
    )
);

When it violate the rule, it would display

> Usernames must only contain letters and numbers.

Let's say If the user enter 'hello123...', If I want it to display the data entered instead of just 'Usernames', for example

> 'hello123...' must only contain letters and numbers.

Is it possible?

Thanks!!!

I'm not 100% sure, but I believe the answer to this is you can't do this at the model validation specification level but instead have to use str_replace or regexp.

So for example you try to save and get invalidFields (controller level)


$this->MyModel->save($this->data);
$errors = $this->MyModel->invalidFields();

Then you would need to search and replace the keywords with whichever variables you needed (assume that the username is stored in var $username)


if (isset($errors['login'])){
    $errors['login'] = str_replace('Usernames', $username, $errors['login']);
}

Then you can pass these up to the view for the user to see.
