Laravel 8 Try Catch in Controller Tutorial Example
Below is the syntax that represents the try..catch statement:

try { // run your code here } catch (exception $e) { //code to handle the exception } |

Find Product By Title
Let’s take a look example of laravel try catch. Here you have product table and find the product with it’s title. So you have the following method in controller to find product by it’s title:
|
1 2 3 4 5 6 7 8 9 |
public function search(Request $request) { try { $product = Product::where('title',$request->get('title')); } catch (ModelNotFoundException $exception) { return back()->withError($exception->getMessage())->withInput(); } return view('product.search', compact('product')); } |
With try…catch we have implemented error handling in the above example code. Now if there is no error we can directly pass product data to blade file. But if there is error we can pass errors to blade file. If you want to display an error in Blade file, you can do look like:
|
1 2 3 4 5 6 7 |
<h3 class="page-title text-center">Search by proudct title</h3> @if (session('error')) <div class="alert alert-danger">{{ session('error') }}</div> @endif <form action="{{ route('product.search') }}" method="POST">...</form> |
Note:- DO remember to set APP_DEBUG=false in .env file.
