How to Make Custom Error Messages on Laravel Precognition: A Step-by-Step Guide

Are you tired of those generic error messages that leave your users feeling frustrated and confused? Do you want to take control of your error handling and provide a better user experience? Look no further! In this article, we’ll show you how to make custom error messages on Laravel Precognition, the popular PHP framework.

Why Custom Error Messages Matter

Custom error messages are essential for any web application. They help you:

• Provide a better user experience by giving users clear and concise error messages
• Enhance your application’s security by hiding internal server errors
• Improve your debugging process by providing more informative error messages
• Stand out from the competition by offering a more personalized experience

Understanding Laravel’s Error Handling

Laravel provides a robust error handling system that allows you to catch and handle errors in a centralized way. By default, Laravel uses the `ExceptionHandler` class to handle errors. This class is located in the `app/Exceptions` directory.

// app/Exceptions/Handler.php
namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

class Handler extends ExceptionHandler
{
    public function report(Exception $exception)
    {
        parent::report($exception);
    }

    public function render($request, Exception $exception)
    {
        return parent::render($request, $exception);
    }
}

Creating Custom Error Messages

To create custom error messages, you need to override the `render` method in the `ExceptionHandler` class. This method is responsible for rendering the error page.

Step 1: Define Your Error Codes

Create a new file called `ErrorCodes.php` in the `app/Exceptions` directory. In this file, define your error codes as constants.

// app/Exceptions/ErrorCodes.php
namespace App\Exceptions;

abstract class ErrorCodes
{
    const INVALID_REQUEST = 400;
    const UNAUTHORIZED_ACCESS = 401;
    const RESOURCE_NOT_FOUND = 404;
    const INTERNAL_SERVER_ERROR = 500;
}

Step 2: Override the `render` Method

In the `ExceptionHandler` class, override the `render` method to handle errors based on their error codes.

// app/Exceptions/Handler.php
namespace App\Exceptions;

use App\Exceptions/ErrorCodes;
use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

class Handler extends ExceptionHandler
{
    public function render($request, Exception $exception)
    {
        switch ($exception->getCode()) {
            case ErrorCodes::INVALID_REQUEST:
                return response()->view('errors.invalid-request', [], 400);
            case ErrorCodes::UNAUTHORIZED_ACCESS:
                return response()->view('errors.unauthorized-access', [], 401);
            case ErrorCodes::RESOURCE_NOT_FOUND:
                return response()->view('errors.resource-not-found', [], 404);
            case ErrorCodes::INTERNAL_SERVER_ERROR:
                return response()->view('errors.internal-server-error', [], 500);
            default:
                return parent::render($request, $exception);
        }
    }
}

Step 3: Create Error Views

@extends('layouts.master')

@section('content')
  
  
Sorry, it looks like you made an invalid request.
