Understanding Laravel validation rules and how to apply them is a key skill for backend developers working with Laravel frameworks.

1

Create the validation rules array

Create a PHP array called $rules with these exact keys and rules: 'name' => 'required', 'email' => 'required|email', 'age' => 'nullable|numeric'.

Laravel

<?php

// Create the $rules array with name, email, and age validation
// Your code here

Need a hint?

Use Laravel's validation rule strings separated by pipes (|) for multiple rules.

2

Add password validation rules

Add to the $rules array the keys 'password' with rules 'required|min:8' and 'password_confirmation' with rule 'required|same:password'.

Laravel

 'required',
    'email' => 'required|email',
    'age' => 'nullable|numeric',
    // Add password and password_confirmation rules here
];

Need a hint?

Use min:8 to require at least 8 characters and same:password to confirm the password.

3

Use the validation rules in a controller method

Inside a Laravel controller method, write the line $validatedData = $request->validate($rules); to apply the validation rules.

Laravel

 'required',
    'email' => 'required|email',
    'age' => 'nullable|numeric',
    'password' => 'required|min:8',
    'password_confirmation' => 'required|same:password',
];

// Inside a controller method
public function store(Request $request)
{
    // Validate the request data
    // Your code here
}

Need a hint?

Use the validate method on the $request object with the $rules array.

4

Complete the controller method with data saving

Add the line User::create($validatedData); after validation to save the user data, assuming the User model is imported.

Laravel

 'required',
    'email' => 'required|email',
    'age' => 'nullable|numeric',
    'password' => 'required|min:8',
    'password_confirmation' => 'required|same:password',
];

// Inside a controller method
public function store(Request $request)
{
    $validatedData = $request->validate($rules);
    // Save the validated data
    // Your code here
}

Need a hint?

Use the User::create() method to save the validated data to the database.
