Force Laravel FormRequest to fail

Question

In my custom Request, in the rules method, I'm checking a few things before returning the rules array.

I would like to make the validation fail as soon as I found some errors I can't check by the default validation rules.

So I would like to have something like this:

public function rules() {
  $rules = [
     'first_parameter' => 'required'
  ];

  if( someErrorCondition ) {
     // here i would like to make the rules method always fail the validation
  }

  return $rules;
}

What's the best approach to deal with it?

而是创建一个自定义验证规则 。

You're using the complete wrong method.

Your rules list is a basic list of rules to perform validation on.

For additional logic, either add it into the controller (at the expense of your sanity later on), or use a custom rule .

If you need to restrict users based on permissions, etc. then use the authorize method.
