Testing Validation Rules in A Laravel Livewire Component

Testing validation rules can become quite tiresome pretty quickly if you have to write each test manually. Luckily I’ve found a nice method that allows you to simplify your validation rule tests when using Laravel Livewire components. For this example we have a form that allows a user to update their profile information with a Livewire ProfileForm component.

In Livewire you can define validation rules by setting a rules array (shown below) and then validate using $this->validate(). In this example we are  binding to a User model that has a name, email and bio.

protected $rules = [
    'user.name' => 'required|max:200',
];

In our example we need to do something a bit more complicated so instead of using the rules array we are going to create a rules function instead, allowing us to use the Illuminate\Validation\Rule::class. Here are the rules we have set and the save() method that will validate the input.

// App\Http\Livewire\ProfileForm.php

use Illuminate\Validation\Rule;

protected function rules() 
{
    return [
        'user.id' => 'required',
        'user.name' => 'required|max:200',
        'user.email' => ['required', 'email', Rule::unique('users')->ignore($this->user->id)],
        'user.bio' => 'required|min:20|max:1000',
    ];
}

public function save()
{
    $this->validate();

    // Save the user data
    $this->user->save();
}

So how can we go about testing each of these rules? There are 8 different validation rules in this simple example, but you don’t want to have to write 8 separate tests for each rule. Instead, we can make use of a data provider to pass the data to be tested into the test, along with the expected validation rule.

How to validate mobile phone number in laravel with example

Data validation and sanitization is a very important thing from security point of view for a web application. We can not rely on user’s input. In this article i will let you know how to validate mobile phone number in laravel with some examples.

if we take some user’s information in our application, so usually we take phone number too. And if validation on the mobile number field is not done, a user can put anything in the mobile number field and without genuine phone number, this data would be useless.

Since we know that mobile number can not be an alpha numeric or any alphabates aand also it should be 10 digit number. So here in this examples we will add 10 digit number validation in laravel application.

We will aalso see the uses of regex in the validation of mobile number. So let’s do it with two different way in two examples.

Example 1:

In this first example we will write phone number validation in HomeController where we will processs user’s data.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;

class HomeController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('createUser');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
                'name' => 'required',
                'phone' => 'required|digits:10',
                'email' => 'required|email|unique:users'
            ]);

        $input = $request->all();
        $user = User::create($input);

        return back()->with('success', 'User created successfully.');
    }
}

Example 2:

In this second example, we will use regex for user’s mobile phone number validation before storing user data in our database. Here, we will write the validation in Homecontroller like below.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\User;
use Validator;

class HomeController extends Controller
{
    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('createUser');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
                'name' => 'required',
                'phone' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:10',
                'email' => 'required|email|unique:users'
            ]);

        $input = $request->all();
        $user = User::create($input);

        return back()->with('success', 'User created successfully.');
    }
}
