In this tutorial, we will see how to use try catch in laravel. You can easily use try catch in laravel.

Given below is the step-by-step process for how to handle errors.




Step 1: Create Route


routes/web.php

Route::get('/users', 'UserController@index')->name('users.index');
Route::post('/users/search', 'UserController@search')->name('users.search');



Step 2: Create Controller


app/http/controller/UserController.php

<?php
     
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Database\Eloquent\ModelNotFoundException;
use App\User;

class UserController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return view('users.index');
    }

    public function search(Request $request)
    {
        try {
            $user = User::findOrFail($request->input('user_id'));
        } catch (ModelNotFoundException $exception) {
            return back()->withError($exception->getMessage())->withInput();
        }
        return view('users.search', compact('user'));
    }
}



Step 3: Create Blade File


/resources/views/users/index.blade.php

     <title></title>
     <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.0/css/bootstrap.min.css" integrity="sha512-rO2SXEKBSICa/AfyhEK5ZqWFCOok1rcgPYfGOqtX35OyiraBg6Xa4NnBJwXgpIRoXeWjcAmcQniMhp22htDc6g==" crossorigin="anonymous" />
</head>
<body>
     <div class="container mt-5">
          <div class="col-md-8 offset-2">
          		<h2 class="text-center">laravel try catch Example - Rathorji.in</h2>
               <div class="card">
                    <div class="card-header text-center">

                    </div>
                    <div class="card-body">
                         @if (session('error'))
                              <div class="alert alert-danger">{{ session('error') }}</div>
                         @endif
                         <form action="{{ route('users.search') }}" method="POST">
                              @csrf
                              <div class="form-group">
                                   <input id="user_id"  name="user_id" class="form-control" type="text" value="{{ old('user_id') }}" placeholder="User ID">
                              </div>

                </div>
                <div class="card-body">
                    <table class="borded">
                        <tr>
                            <td>Name :</td>
                            <td>{{ $user->name }}</td>
                        </tr>
                        <tr>
                            <td>Email :</td>
                            <td>{{ $user->email }}</td>
                        </tr>
                    </table>
                </div>
            </div>
