How to Add Custom Error Messages in Laravel 12
When I started working with Laravel 12, I realized the importance of customizing error messages to provide a better user experience. Default messages can be generic and might not convey the exact issue to the user.
In this guide, I'll walk you through the steps to add custom error messages in Laravel 12, making your application more user-friendly and professional.
Step-by-Step Guide: Adding Custom Error Messages in Laravel 12
Example: Custom Error Messages in a Finance or Insurance Form
Let's say you're building a Term Insurance Plans application form or a Car Insurance quote request form using Laravel 12.
In your routes/web.php
use App\Http\Controllers\InsuranceController;
Route::get('/insurance/apply', [InsuranceController::class, 'showForm'])->name('insurance.form');
Route::post('/insurance/apply', [InsuranceController::class, 'submitForm'])->name('insurance.apply');
Run:
php artisan make:controller InsuranceController
Inside app/Http/Controllers/InsuranceController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class InsuranceController extends Controller
{
public function showForm()
{
return view('insurance.form');
}
public function submitForm(Request $request)
{
$request->validate(
[
'full_name' => 'required|string|max:255',
'email' => 'required|email|unique:insurance_quotes,email',
'age' => 'required|numeric|min:18|max:70',
'insurance_type' => 'required|in:term,health,car',
],
[
'full_name.required' => 'Please enter your full name for the insurance application.',
'email.required' => 'A valid email is required to receive your term insurance quote.',
'email.unique' => 'This email has already been used to request a car insurance quote.',
'age.required' => 'Age is required to determine your eligibility for insurance plans.',
'age.min' => 'Applicants must be at least 18 to apply for health insurance.',
'age.max' => 'Sorry, our term insurance plans are limited to applicants under 70.',
'insurance_type.required' => 'Please select your insurance category: term, health, or car.',
'insurance_type.in' => 'Invalid selection. Choose from term insurance, health, or car insurance.',
]
);
// Store logic (optional)
return back()->with('success', 'Your insurance quote request has been submitted!');
}
}
Create file: resources/views/insurance/form.blade.php
