Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

$ composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Example #1: Check If Array Key Exists in Blade

To check if array key exists or not in laravel blade or not, we will use @isset() directive.

Let’s consider a controller i.e UserController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function index()
    {
        $data = [
            "username" => "sanjay_owt",
            "email" => "sanjay_sample@example.net"
        ];

        return view('user.index',compact('data'));
    }
}

Next,

To create a view file: Go to /resources/views folder. Create a folder called user. Inside that folder create a file with name index.blade.php

Code of blade view file:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel Blade Check if Array Key Exists Example Tutorial</title>
</head>
<body>
    
@isset($data['username'])
    <p>Username Key Exists</p>
@endisset
    
</body>
</html>
    

Here, the above code checking $data[‘username’], username key exists inside $data array or not.

Also, in any case if you need to check key within any multidimensional inside array then also you can do that.

Example #2: Check If Array Key Exists in Blade

To check if array key exists or not in laravel blade or not, we will use @isset() directive.

Again, let’s consider a controller i.e UserController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UserController extends Controller
{

    /**
     * Write Your Code..
     *
     * @return string
    */
    public function index()
    {
        $data = [
            "user" => [
               "username" => "sanjay_owt",
               "email" => "sanjay_sample@example.net",
               "phone" => "1234567890"
            ]
        ];

        return view('user.index',compact('data'));
    }
}

Next,

To create a view file: Go to /resources/views folder. Create a folder called user. Inside that folder create a file with name index.blade.php

Code of blade view file:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel Blade Check if Array Key Exists Example Tutorial</title>
</head>
<body>
    
@isset($data['user']['email'])
    <p>Email Key Exists</p>
@endisset
    
</body>
</html>
    

Here, the above code checking $data[‘user’][’email’], email key exists within user array inside $data array or not.
