💼 Career

Laravel developers frequently use the validate method on requests to enforce data rules before processing.

1

Create the controller method with Request parameter

Create a public method called store inside a controller that accepts a Request parameter named $request.

Laravel

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{
    // Create the store method with Request parameter
    // Your code here
}

Need a hint?

Remember to declare the method as public and accept Request $request as the parameter.

2

Add validation rules using the validate method

Inside the store method, use $request->validate() to validate that name is required and minimum 3 characters, and email is required and a valid email.

Laravel

validate() with rules for name and email
        // Your code here
    }
}

Need a hint?

Use an array inside validate() with keys 'name' and 'email' and their validation rules.

3

Add a success response after validation

After the $request->validate() call, return a string 'Validation passed!' from the store method.

Laravel

validate([
            'name' => ['required', 'min:3'],
            'email' => ['required', 'email'],
        ]);
        // Return 'Validation passed!' string
        // Your code here
    }
}

Need a hint?

Simply return the string after validation to confirm success.

4

Complete the controller with namespace and use statements

Ensure the controller file starts with the correct namespace App\Http\Controllers; and includes use Illuminate\Http\Request; at the top.

Laravel

validate([
            'name' => ['required', 'min:3'],
            'email' => ['required', 'email'],
        ]);

        return 'Validation passed!';
    }
}

Need a hint?

The namespace and use statements must be at the top of the file before the class.
