Validation under array validation in laravel

Question

If I have an array validation rule, how can I check if all the items in the array is a valid email? I'm using this: https://laravel.com/docs/5.1/validation#rule-array for the array validation rule.

$this->validate($request, [
 'email' => 'required|array.email'
]);

Note: I'm using laravel 5.1 version

Update - as per request.

Answer 1

checked is validate:

above 5.2

$this->validate($request, [
 'email.*' => 'required|array|email'
],[
 'email.required' => 'message required',
 'email.array' => 'message array',
 'email.email' => 'message email',
]);

OR

Less than 5.2

 $validator = \Validator::make($request->all(), [
 'email' => 'array',
 /* Other rules */
 ],[
 'email.required' => 'message required',
 'email.array' => 'message array',
 'email.email' => 'message email',
 ]);
 $validator->each('email', 'required|email');
 if($validator->fails()) 
 return back()->withErrors($validator->errors());
 dd('Success All Email ;)');

• Blues Clues: I don't think this would work. I'm using laravel 5.1 version.
• Mohammad: @Jonjie Have you tested?
• Blues Clues: Nice. Can you also include the link for $validator->each('email', 'required|email');?
• Mohammad: github.com/laravel/framework/issues/5645#issuecomment-68328399 | github.com/laravel/framework/issues/5645#issuecomment-68362955
• Blues Clues: This works fine. Alright, one more thing. How can I customize the message for the email validation rule?

Answer 2

You need custom validator. In Laravel Request you can do something like that

public function __construct() {
 Validator::extend("emails", function($attribute, $value, $parameters) {
 $rules = [
 'email' => 'required|email',
 ];
 foreach ($value as $email) {
 $data = [
 'email' => $email
 ];
 $validator = Validator::make($data, $rules);
 if ($validator->fails()) {
 return false;
 }
 }
 return true;
 });
}
public function rules() {
 return [
 'email' => 'required|emails'
 ];
}

Or

Validating Arrays laravel 5.2 onwards :

Validating array form input fields doesn't have to be a pain. For example, to validate that each e-mail in a given array input field is unique, you may do the following:

$validator = Validator::make($request->all(), [
 'person.*.email' => 'email|unique:users',
 'person.*.first_name' => 'required_with:person.*.last_name',
]);

Likewise, you may use the * character when specifying your validation messages in your language files, making it a breeze to use a single validation message for array based fields:

'custom' => [
 'person.*.email' => [
 'unique' => 'Each person must have a unique e-mail address',
 ]
],

Hope this helps you.
