SQLSTATE [23000]: Integrity limitation violation: 1062 '[email protected]' duplicate entry for 'users_email_unique' key

I have a registration form. When the email is registered in the database it gets an error message

SQLSTATE [23000]: Violation of integrity restrictions: 1062 Duplicate entry '[email protected]' for 'users_email_unique' key

I want to avoid that mistake and instead get a warning like "registered email" or something similar. Any help is appreciated. This is my code.

you must use laravel validation in your controller for validate request parameters.

first add this use top of your controller

use Illuminate\Support\Facades\Validator;

then in your registercontroller define this method


    public function register(Request $request)
    {

        $validator = Validator::make($request->all(), [
            'email' => 'required|email|unique:users',
            'password' => 'required|max:10',
            'name' => 'nullable|string|max:50',
        ]);

        if ($validator->fails()) {
            $response = $validator->errors();
            session()->flash('flash_error', $response);
            return redirect()->back();
        }

        /**
         * create new user
         */
        try {


            /**
             * new user
             */
            User::create([
                'name' => $request->name,
                'email' => $request->email,
                'password' => Hash::make($request->password),
            ]);
        } catch (Exception $e) {
            throw new HttpException(500, $e->getMessage());
        }

        session()->flash('flash_success', 'you are registered.');
        return redirect()->back();
    }

by default email field in laravel is unique and for validate it we use this exception :

unique:users

users is table name.

to learn more about laravel validation

see this link https://laravel.com/docs/7.x/validation

to access validation errors in view file we pass errors flash session with name flash_error you can show it for example like this:

@if(session()->has('flash_error'))
    <ul>
         @foreach(session()->get('flash_error') as $error)
            <li>{{ session()->get('flash_error') }}</li>
         @endforeach
    </ul>
@endif

and show success message with bootstrap like this:

@if(session()->has('flash_success'))
    <div class="alert alert-success" role="alert">
       {{ session()->get('flash_success') }}
    </div>   
@endif

You have to use like this. Remove unique:users from validation

return Validator::make($data, [
    'name' => 'required|min:4',
    'id_level' => 'required',
    'email' => 'required|min:4|email',
    'password' => 'required',
    'confirm' => 'required|same:password',
    'g-recaptcha-response' => 'required|captcha',
]);
