Websolutionstuff | Dec-23-2022 | Categories : Laravel PHP

In this article, we will see special characters not allowed validation in laravel 9. Here, we will learn special character is not allowed in the textbox. Sometimes we required validation for input textbox. In the textbox special character is not allowed only allow characters and numbers are allowed.

We will create alphanumeric validation in laravel 7, laravel 8, and laravel 9. So, we will give you an example of validation in laravel 7/8/9.

So, let's see laravel 9 special characters not allowed validation and special characters not allowed regex example.

Example 1:

In this example, we will use the laravel alpha validation rule. The alpha rule only allows alphabets. So, add the following code to your file or controller.

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\User;
    
class UserController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('index');
    }
    
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
                'name' => 'required|alpha',
                'email' => 'required|email|unique:users'
            ]);
     
        $input = $request->all();
        $user = User::create($input);
      
        return back()->with('success', 'User created successfully.');
    }
}

 

Example 2:

In this example, we will use the laravel alpha_num validation rule. The alpha_ num rule allows alphabets and numbers. So, add the following code to your file or controller.

<?php
   
namespace App\Http\Controllers;
   
use Illuminate\Http\Request;
use App\User;
   
class UserController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('index');
    }
    
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
                'name' => 'required|alpha_num',
                'email' => 'required|email|unique:users'
            ]);
     
        $input = $request->all();
        $user = User::create($input);
      
        return back()->with('success', 'User created successfully.');
    }
}

 

Example 3:

In this example, we will use the regex validation rule.

<?php
    
namespace App\Http\Controllers;
    
use Illuminate\Http\Request;
use App\User;
    
class UserController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('index');
    }
    
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
                'name' => 'required|regex:/^[a-zA-Z]+$/u',
                'email' => 'required|email|unique:users'
            ]);
     
        $input = $request->all();
        $user = User::create($input);
      
        return back()->with('success', 'User created successfully.');
    }
}
