How to validate phone number in laravel 5.2? [closed]

Question

I want to validate user input phone number where number should be exactly 11 and started with 01 and value field should be number only. How do I do it using Laravel validation?

Here is my controller:

  public function saveUser(Request $request){         $this->validate($request,[             'name' => 'required|max:120',             'email' => 'required|email|unique:users',             'phone' => 'required|min:11|numeric',             'course_id'=>'required'             ]);          $user = new User();         $user->name=  $request->Input(['name']);         $user->email=  $request->Input(['email']);         $user->phone=  $request->Input(['phone']);         $user->date = date('Y-m-d');         $user->completed_status = '0';         $user->course_id=$request->Input(['course_id']);         $user->save();        return redirect('success');      }

One possible solution would to use regex.

'phone' => 'required|regex:/(01)[0-9]{9}/' 

This will check the input starts with 01 and is followed by 9 numbers. By using regex you don't need the numeric or size validation rules.

If you want to reuse this validation method else where, it would be a good idea to create your own validation rule for validating phone numbers.

Docs: Custom Validation

In your AppServiceProvider's boot method:

Validator::extend('phone_number', function($attribute, $value, $parameters) {     return substr($value, 0, 2) == '01'; }); 

This will allow you to use the phone_number validation rule anywhere in your application, so your form validation could be:

'phone' => 'required|numeric|phone_number|size:11' 

In your validator extension you could also check if the $value is numeric and 11 characters long.
