            $table->timestamps();
        });
    }

Route::post('/store-product','ProductController@storeProduct')->name('store.product');
Route::get('/list-product','ProductController@ListProduct')->name('list.product');

Functionality & Logic

App\Http\Controllers\ProductController

In the ProductController we write Logic for storing the parameters and generate unique numbers for our products.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Product;

class ProductController extends Controller
{
    public function addProduct(){
     return view('product.add');
    }

    public function storeProduct(Request $request){
     $product = new Product();
     $product->name = $request->product_name;
     $product->description = $request->product_desc;
     
     #Store Unique Order/Product Number
     $unique_no = Product::orderBy('id', 'DESC')->pluck('id')->first();
        if($unique_no == null or $unique_no == ""){
        #If Table is Empty
        $unique_no = 1;
        }
        else{
        #If Table has Already some Data
        $unique_no = $unique_no + 1;
      }
     $product->product_no = 'PROD'.$unique_no;
     $product->save();
     return redirect()->route('list.product');
    }

    public function ListProduct(){
      $productList = Product::get();
      return view('product.list',compact('productList'));
    }
}

Create Blade Files

In the resources/views directory, we create product folder, under product folder we create 2 blade files.

  1. add.blade.php 2. list.blade.php
