Forum Custom Validation Method

posted 10 years ago

I am new to Laravel coming from another framework and needing some help creating a custom validation method.

Basic example is a model that has a foreign_id take User->country_id for example when saving the select form Australia with value of 36 how can i check that the Country Model does infact have a ID of 36

In the other framework I simply created a public function checkModelValues($data, $field, $model, $modelField){ return $this->$model->hasAny(array($modelField => $data[$field])); }

So this ensured that the $model (Countries) has a $modelField (id) that has a value of $data[$field] (36)

How would you go about creating this in Laravel so it can be used anytime you need to validate a foreign_key.

Thanks, Dave

I guess you don't even to have to build a custom validation rule.

Just by using the Exists built-in validation rule : http://laravel.com/docs/validation#rule-exists

Like in your case :

$country_id =  Input::get('country_id')
'country_id' => "exists:Countries,id,$country_id"

With the validator :

$validator = Validator::make(
    array(
        'country_id' => $country_id,
    ),
    array(
        'country_id' => "exists:Countries,id,$country_id"
    )
);
