How to Make Form Validation in Laravel Inertia and Vue
In this lesson, we are going to see how to make form validation in Laravel Inertia js and Vue js, let's assume that we have a task application and we want to validate a form before storing a new task.
Create the controller
Inside the controller, before we store the new task we validate the data coming from the form.
<?php
namespace App\Http\Controllers;
use App\Models\Task;
use Illuminate\Http\Request;
class TaskController extends Controller
{
/**
* Store a newly created resource in storage.
*/
public function store(Request $request)
{
//
$this->validate($request, [
'title' => 'required',
'body' => 'required',
'category_id' => 'required',
]);
Task::create([
'title' => $request->title,
'body' => $request->body,
'category_id' => $request->category_id,
]);
return redirect()->route('home')->with([
'message' => 'Task added successfully',
'class' => 'alert alert-success'
]);
}
}
Display the form validation errors
To display the form validation errors in your component you can use the form helper provided by inertia js.
