Questions:

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');

    }
How to&Answers:

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.

Answer:

From Laravel 5.5 on you can use an artisan command to create a new Rule which you can code regarding your requirements to decide whether it passes or fail.

Ej:
php artisan make:rule PhoneNumber

Then edit app/Rules/PhoneNumber.php, on method passes

/**
 * Determine if the validation rule passes.
 *
 * @param  string  $attribute
 * @param  mixed  $value
 * @return bool
 */
public function passes($attribute, $value)
{

    return preg_match('%^(?:(?:\(?(?:00|\+)([1-4]\d\d|[1-9]\d?)\)?)?[\-\.\ \\/]?)?((?:\(?\d{1,}\)?[\-\.\ \\/]?){0,})(?:[\-\.\ \\/]?(?:#|ext\.?|extension|x)[\-\.\ \\/]?(\d+))?$%i', $value) && strlen($value) >= 10;
}

Then, use this Rule as you usually would do with the validation:

use App\Rules\PhoneNumber;

$request->validate([
    'name' => ['required', new PhoneNumber],
]);

docs

Answer:

Validator::extend('phone', function($attribute, $value, $parameters, $validator) {
        return preg_match('%^(?:(?:\(?(?:00|\+)([1-4]\d\d|[1-9]\d?)\)?)?[\-\.\ \\/]?)?((?:\(?\d{1,}\)?[\-\.\ \\/]?){0,})(?:[\-\.\ \\/]?(?:#|ext\.?|extension|x)[\-\.\ \\/]?(\d+))?$%i', $value) && strlen($value) >= 10;
    });

Validator::replacer('phone', function($message, $attribute, $rule, $parameters) {
        return str_replace(':attribute',$attribute, ':attribute is invalid phone number');
    });

Usage

Insert this code in the app/Providers/AppServiceProvider.php to be booted up with your application.

This rule validates the telephone number against the given pattern above that i found after
long search it matches the most common mobile or telephone numbers in a lot of countries
This will allow you to use the phone validation rule anywhere in your application, so your form validation could be:

 'phone' => 'required|numeric|phone' 

Answer:

Use
required|numeric|size:11
Instead of
required|min:11|numeric

Answer:

You can try out this phone validator package. Laravel Phone

Update

I recently discovered another package Lavarel Phone Validator (stuyam/laravel-phone-validator), that uses the free Twilio phone lookup service

Answer:

You can simple use :

        'mobile_number' => ['required', 'digits:10'],

Answer:

There are a lot of things to consider when validating a phone number if you really think about it. (especially international) so using a package is better than the accepted answer by far, and if you want something simple like a regex I would suggest using something better than what @SlateEntropy suggested. (something like A comprehensive regex for phone number validation)

Answer:

I used the code below, and it works

'PHONE' => 'required|regex:/(0)[0-9]/|not_regex:/[a-z]/|min:9',

Answer:

$request->validate([
    'phone' => 'numeric|required',
    'body' => 'required',
]);
