Using form request specific custom validation attributes

Question

Using Laravel's localization (http://laravel.com/docs/5.1/localization) I have created some custom validation attributes to provide friendlier validation errors (for instance, 'First Name' instead of first name etc).

I am using form requests (http://laravel.com/docs/5.1/validation#form-request-validation) in order to validate user submissions and there are scenarios where I would like to provide store-specific custom validation attributes (for instance, I may have a 'name' field that is Brand Name in one context, and Product Name in another).

The messages() method allows me to specify validation rule specific message overrides, but that isn't ideal as it's not the validation message as such we need to override, just the attribute name (for example, if we have 5 validation rules for 'email', we have to provide 5 overrides here, rather than one override for, let's say, Customer Email).

Is there a solution to this? I note references to formatValidationErrors() and formatErrors() in the Laravel documentation, but there is not really any information on how to correctly override these, and I've not had much luck in trying.

You can override the attribute names, which is defaulting to whatever the field name is.

With form request

In your form request class override the attributes() method:

public function attributes()
{
    return [
        'this_is_my_field' => 'Custom Field'
    ];
}

With controller or custom validation

You can use the 4th argument to override the field names:

$this->validate($request, $rules, $messages, $customAttributes);

or

Validator::make($data, $rules, $messages, $customAttributes);

Simple working example

Route::get('/', function () {
    // The data to validate
    $data = [
        'this_is_my_field' => null
    ];

    // Rules for the validator
    $rules = [
        'this_is_my_field' => 'required',
    ];

    // Custom error messages
    $messages = [
        'required' => 'The message for :attribute is overwritten'
    ];

    // Custom field names
    $customAttributes = [
        'this_is_my_field' => 'Custom Field'
    ];

    $validator = Validator::make($data, $rules, $messages, $customAttributes);

    if ($validator->fails()) {
        dd($validator->messages());
    }

    dd('Validation passed!');
});

Martinseon - thanks, but I believe this isn't in the context I was looking for - using it within form request store.

I've added more info of the usage within the context of form request validations.

Thanks, that helps a lot and encompasses my own answer too.

Yeah, I often find it more useful just digging through the source rather than the docs. There's so much cool code that isn't documented. You'll often get a better understanding of how it all works than with the docs as well.

As detailed in my question, I was looking for a way to provide specific form request stores (http://laravel.com/docs/5.1/validation#form-request-validation) with custom attribute names.

The Laravel documentation only covers two methods for Requests in this context - rules() and authorize(). I was aware there is a messages() method to provide validation specific custom error messages, but it also appears there is an attributes() method, which fits my requirements exactly:

public function attributes()
{
     return [
         'name' => 'Product Name'
     ]
}

This overrides the attribute name in the context of my store.
