Laravel Inertia Vue 3 Form Validation

In this short tutorial we will see how to validate form data using laravel inertia vue 3. For this section we will use Vue 3 SFCs method <script setup>.


1. Create simple CategoryController.php and validate & store data.

public function store(Request $request)
{
    $request->validate([
        'name' => 'required|string|max:255',
        'slug' => 'required|string|max:255',
    ]);

    Category::create([
        'name' => $request->name,
        'slug' => \Str::slug($request->slug)
    ]);
    sleep(1);

    return redirect()->route('category.index')->with('message', 'Category Created Successfully');
}

OR

2) Create CategoryStoreRequest.php request to validation rule.

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class CategoryStoreRequest extends FormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array<string, mixed>
     */
    public function rules()
    {
        return [
            'name' => 'required|string|max:255',
            'slug' => 'required|string|max:255',
        ];
    }
}


CategoryController.php

public function store(CategoryStoreRequest $request)
{
    Category::create($request->validated());
    sleep(1);
    return redirect()->route('category.index')->with('message', 'Category Created Successfully');
}
