LARAVEL FRAMEWORK BASICS পর্ব-১৮: Creating Multi Step Form Validation With Laravel Session

Multi Step Form Validation With Laravel Session
Multi Step Form Validation With Laravel Session

বিভিন্ন ধরণের প্রজেক্টে Multi Step Form Validation একটি খুবই সাধারণ বিষয়। আজকের পর্বে আমরা Validation সহ Laravel Session ব্যবহার করে একটি Multi Step Form Validation উদাহরণ দেখব। এবং এই Multi Step Form তৈরি করতে কোনো JavaScript Library বা Framework ব্যবহার করা হবে না। এমনকি লারাভেলের কোনো প্যাকেজ এর ও সাহায্য নেওয়া হবেনা। তো চলুন শুরু করা যাক :

Create Migration and Model

প্রথমে চলুন আমরা নিম্নোক্ত Artisan Command ব্যবহার করে Product নামে একটি Model সাথে একটি Migration File তৈরি করব:

1
php artisan make:model Product -m

এবার CreateProductsTable নামক Migration ফাইলে নিচের মতো করে প্রয়োজনীয় Table Column গুলো যুক্ত করে দিন :

01

<?php
 
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
 
return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('products', function (Blueprint $table) {
            $table->id();
            $table->string('name')->nullable();
            $table->longText('description')->nullable();
            $table->float('amount')->nullable();
            $table->boolean('status')->default(0);
            $table->integer('stock')->default(0);
            $table->rememberToken();
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('products');
    }
};

Migration File এর কাজ শেষ হলে নিম্নোক্ত কমান্ডের মাধ্যমে Table Structure তৈরি করে ফেলুন :

1
php artisan migrate

এখন আপনি আপনার ডেটাবেসে নিচের মতো করে টেবিল স্ট্রাকচার দেখতে পাবেন :

products table structure
products table structure

এবার Product নামক Model ফাইলে নিচের মতো করে প্রয়োজনীয় Fillable Column গুলো যুক্ত করে দিন :

01
02
03

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
 
class Product extends Model
{
    use HasFactory;
    protected $fillable = [
        'name', 'amount', 'description', 'status', 'stock'
    ];
}

Add Routes

এবার আমরা আমাদের এই Multi Step Form Validation এর জন্য প্রয়োজনীয় route গুলো define করে দিব:

use App\Http\Controllers\ProductController;
 
 
Route::get('products', [ProductController::class,'index'])->name('products.index');
   
Route::get('products/create-step-one', [ProductController::class,'createStepOne'])->name('products.create.step.one');
 
Route::post('products/create-step-one', [ProductController::class,'postCreateStepOne'])->name('products.create.step.one.post');
 
Route::get('products/create-step-two', [ProductController::class,'createStepTwo'])->name('products.create.step.two');
 
Route::post('products/create-step-two', [ProductController::class,'postCreateStepTwo'])->name('products.create.step.two.post');
 
Route::get('products/create-step-three', [ProductController::class,'createStepThree'])->name('products.create.step.three');
 
Route::post('products/create-step-three', [ProductController::class,'postCreateStepThree'])->name('products.create.step.three.post');

Create Controller

এবার নিম্নোক্ত কমান্ডের মাধ্যমে ProductController টি তৈরি করে ফেলুন :

1
php artisan make:controller ProductController

এখন আমরা Form এর value গুলো multi step এ validation করার জন্য , নিচের মতো করে আপডেট করে নিব।

        $products = Product::all();
   
        return view('products.index',compact('products'));
    }
   
  
    public function createStepOne(Request $request)
    {
        $product = $request->session()->get('product');
   
        return view('products.create-step-one',compact('product'));
    }
   
  
    public function postCreateStepOne(Request $request)

    public function postCreateStepThree(Request $request)
    {
        $product = $request->session()->get('product');
        $product->save();
   
        $request->session()->forget('product');
   
        return redirect()->route('products.index');
    }
}

Add Blade Files

এখন আমরা আমাদের Blade File গুলো নিয়ে কাজ করব। প্রথমে চলুন আমরা resources/views/layout ফোল্ডারের মধ্যে আমাদের Master Blade File default.blade.php File টি তৈরি করে ফেলি :
