How can I validate form data in a Laravel controller using request validation?

I have to build a user registration form for a web application in Laravel. The form should collect the following data from users:

Name: The user's full name. Email: The user's email address. Password: The user's password. Confirm Password: A field to confirm the password.

I have to validate the incoming form data in the controller using Laravel's request validation. The validation should ensure the following:

Name: Required, should only contain letters and spaces. Email: Required, must be a valid email address, and should be unique in the users table. Password: Required, should be at least 8 characters long, containing at least one uppercase letter, one lowercase letter, and one digit. Confirm Password: Should match the Password field.

I tried using the validate() method in my Laravel controller to validate the user registration form data, including name, email, password, and password confirmation. I applied the validation rules for required fields, email format, uniqueness of the email, and password strength. However, the validation did not work as expected, and the form did not return the correct error messages or redirect the user properly. I was expecting the validation to properly check all the fields, show the appropriate error messages if any of the fields failed validation (like wrong password or invalid email), and redirect the user back to the form with these error messages displayed.

Here is solution or overview for your question, I hope it will useful for you...

public function register(Request $request)
{
    // Validate form data
    $request->validate([
        'name' => ['required', 'regex:/^[\pL\s]+$/u', 'max:255'],
        'email' => ['required', 'email', 'unique:users,email'],
        'password' => [
            'required',
            'min:8',
            'regex:/[A-Z]/', // At least one uppercase letter
            'regex:/[a-z]/', // At least one lowercase letter
            'regex:/[0-9]/', // At least one digit
            'confirmed' // Match with password_confirmation
        ],
    ], [
        'name.required' => 'The name field is required.',
        'name.regex' => 'The name can only contain letters and spaces.',
        'email.required' => 'The email field is required.',
        'email.email' => 'Please provide a valid email address.',
        'email.unique' => 'This email address is already registered.',
        'password.required' => 'The password field is required.',
        'password.min' => 'The password must be at least 8 characters long.',
        'password.regex' => 'The password must contain at least one uppercase letter, one lowercase letter, and one digit.',
        'password.confirmed' => 'The password confirmation does not match.',
    ]);

    // Save user data
    User::create([
        'name' => $request->name,
        'email' => $request->email,
        'password' => bcrypt($request->password),
    ]);

    return redirect()->route('login')->with('success', 'Registration successful!');
}

also you can put that validation code in request file create new request file for register form validation using following command

php artisan make:request RegisterRequest

And then add rules and message in their request file function, i suggest this way because you practice that way when code is optimised and also you can reuse in case of crud function
