Laravel 11 / Validation ValidatesWhenResolvedTrait::passedValidation()

Explanation about ValidatesWhenResolvedTrait::passedValidation()

Hello dear friend! Today we want to talk about the method passedValidation() in the ValidatesWhenResolvedTrait trait within the Laravel 11 framework. This method allows us to perform actions after a request and its validation have been completed. In simple terms, when a validation request has been successfully validated, this method is executed and we can write specific codes to handle further processing.

As an example, let's assume we have a registration form. When a user fills out the form and submits it, Laravel first checks the validations. If the validations are correct, passedValidation() is called. This allows us to handle additional information or save data. We might even want to execute specific actions, such as sending a welcome email.

In Laravel, the passedValidation() method is part of the validation controllers and requests. This means you can use it in your own request classes when the data is validated, to carry out specific actions. It's quite interesting, isn't it?

Now, let's dive into the code to see how we can use this method. Below is a simple example of how to use the trait ValidatesWhenResolvedTrait:

namespace App\Http\Requests; 

use Illuminate\Foundation\Http\FormRequest; 

class RegisterRequest extends FormRequest
{
    use ValidatesWhenResolvedTrait;

    public function rules()
    {
        return [
            'name' => 'required|string',
            'email' => 'required|email|unique:users',
            'password' => 'required|string|min:6',
        ];
    }

    protected function passedValidation()
    {
        // Here we can save the user's information
        // or send a welcome email
    }
}

Now, let's explain this code step by step:

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class RegisterRequest extends FormRequest

use ValidatesWhenResolvedTrait;

public function rules()

return [...];

protected function passedValidation()

{ ... }
