Laravel 9 Phone Number Validation Using Regex

In this article, we will see laravel 9 phone number validation using regex. In laravel 9 we will see different methods of validating phone numbers. Also, we will see an example of 10-digit phone number validation in laravel 9 and mobile number validation using regex or regular expression.

So, let's see how to validate phone numbers in laravel 9 and phone number validation regex in laravel 9.

Laravel provides several different methods to validate your application's incoming data. It is most common to use the validate method available on all incoming HTTP requests. The validation rules are passed into the validate method.

 In this example, we will create routes, and a controller and add the rule for 10-digit validation in validate method in the laravel application.

In this step, we will add the following routes in the web.php file.

routes/web.php

use App\Http\Controllers\PostController;
 
Route::get('/post/create', [PostController::class, 'create']);
Route::post('/post', [PostController::class, 'store']);

Now, we will create two functions and add the following code to the controller file. In the store function, we will add validation that must have an exact length of the value. Also, you can use min or max length validation as per requirements.

app/Http/Controllers/PostController.php

<?php
 
namespace App\Http\Controllers;
 
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
 
class PostController extends Controller
{
    /**
     * Show the form to create a new blog post.
     *
     * @return \Illuminate\View\View
     */
    public function create()
    {
        return view('post.create');
    }
 
    /**
     * Store a new blog post.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $validated = $request->validate([
            'phone_number' => 'required|numeric|digits:10'
        ]);
    }
}

The validation rules are passed into the validate method.  all available validation rules are documented.

• If the validation rules pass, your code will keep executing normally;
• however, if validation fails, an Illuminate\Validation\ValidationException exception will be thrown and the proper error response will automatically be sent back to the user.

In this example, we will validate mobile numbers using regular expressions or regex.

<?php
 
namespace App\Http\Controllers;
 
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
 
class PostController extends Controller
{
    /**
     * Show the form to create a new blog post.
     *
     * @return \Illuminate\View\View
     */
    public function create()
    {
        return view('post.create');
    }
 
    /**
     * Store a new blog post.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $validated = $request->validate([
            'phone_number' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:9'
        ]);
    }
}
