Add required method to Request object

[omitobi]

Following up on the same proposal on laravel/ideas#2260

required validation rule is the most popular rule that I have seen and this is used often by developers. This feature adds a new required method to Request object as a shorthand to "validate" and return required fields.

$request->required(['user_id', 'email']) //returns ['user_id' => 1, 'email' => '[email protected]']

The above snippet validates both user_id and email and return an array that is similar to validated() method of FormRequest object.

The benefit is that for a little validation that only requires required rule without creating a Form request or writing custom validation.

Proposal for better naming instead of required is welcomed.

The use case you and the referenced proposal give, require additional validation. the user_id must exist, the email must be a valid e-mail.

Do you have a use case where this is actually useful? I can think of an API-token, but you can already tell if they are there or not using https://laravel.com/docs/master/requests#determining-if-input-is-present

You have a point. I see that $request->filled('name') looks similar to this idea. However, the only thing filled does it to check if the attribute is present and not-empty in the request.

This request->required() would do 4 things

• perform validation for existence
• check if the values are filled
• return the values as array
• throw validation exception if they are invalid

This means we have a shorthand function to both validate, throw validation exception, and retrieved validated (as in with required rule) without adding boilerplate of validation rule.

As for the email and user_id example I gave. Those are just for illustration. The goal is to ensure the required fields are present and filled and we can retrieve them directly.

That's why I asked for a use case. how many use cases can you think of that do not need more validation than just 'required'?

the API-token is a possible use-case, but since laravel has that built in most developers won't use it a lot there.
