Custom Laravel Validation Messages

Custom Laravel validation messages

If you use $this->validate() simplest one, then you should write code something like this..

$rules = [
        'name' => 'required',
        'email' => 'required|email',
        'message' => 'required|max:250',
    ];

    $customMessages = [
        'required' => 'The :attribute field is required.'
    ];

    $this->validate($request, $rules, $customMessages);

How to custom message validator with Laravel

On the Request php file you can use this function failedValidation() and pass in a Validator. This way you can alter or customize the response if validation fails.

use Illuminate\Http\Exceptions\HttpResponseException;
use Illuminate\Contracts\Validation\Validator;

    protected function failedValidation(Validator $validator) {
        throw new HttpResponseException(response()->json(['status'=>'failed',
                                                    'message'=>'unprocessable entity',
                                                    'errors'=>$validator->errors()->all()], 422));
    }

Sample response is here..

{
"status": "failed",
"message": "unprocessable entity",
"errors": [
    "The name must be a string.",
    "One or more users is required"
 ]
}

As you can see the message is changed now you can do whatever you want on the response message.

Also you can try this

$validator->errors()->messages()[keyname]

custom validation message in laravel 8

You can use custom validator. Check the documentation. You can get messages from $errors variable in blade template.

$validator = Validator::make($request->all(), [
    'title' => 'required|unique:posts|max:255',
    'body' => 'required',
], [
    'title.required' => 'Title required custom message',
    'title.unique' => 'Title unique custom message',
    // ...
]);

if ($validator->fails()) {
    return redirect()->back()
                ->withErrors($validator)
                ->withInput();
}

If you want to send redirect with data. You can use

redirect()->route('route')->with('data', 'test');

You can get after redirect

session('data')

        'email' => 'required|string|unique:users,email',
        'password' => 'required|string|confirmed',
        'accept' => 'accepted'

    ];

    $this->validate($request, $rules, $customMessages);

How to set laravel custom validation message with laravel rules

You may customize the error messages used by the form request by overriding the messages() method. Add custom messages on your Venue class as follows-

public static function messages($id = '') {
return [
    'name.required' => 'You must enter your name',
    'logo.required' => 'You must upload logo',
    'key.rules' => 'your messages'
];

And on your controller add messages as third parameter like-

$this->validate($request, Venue::rules(), Venue::messages());
