Programatically add Products

i need to write a Plugin which Programatically add Products to nopCommerce. can anyone help me how can i achieve it ? please explain me with code.

To write the plugin follow this guide: https://www.nopcommerce.com/docs/77/how-to-write-a-nopcommerce-plugin.aspx

When you have your plugin setup, look at the admin ProductsController's POST-method "Create", to see how you can add products. Presentation/Nop.Admin/Controllers/ProductController.cs Line: 612

If you want to add more than just the product itself (prices, images, meta etc), you can take a look at ImportManager.cs
Libraries/Nop.Services/ExportImport/ImportManager.cs Line: 53

Hope that helps!

thanks for the reply, as i am newbie so i am having trouble in writing plugins based on MVC? i have read the differnet articles "how to write plugins" but i cant find any simple example. would you please specify here with some code and steps how can i write a plugin which adds products?

I don't think you can find a better/simpler explanation on how to build a nopCommerce plugin than that. What part of the article are you having trouble understand? It indeed demands basic knowledge of ASP.NET MVC.

The Controller part, i am confused about using it in order to add product to nopCommerce database. Can you just place a snippet here for adding a product ? also in MVC we have a model, do i have to add a Product model too? i can directly use the Product class if any from nopCommerce library.

This is my Controller looks like, please guide me this is correct. Also tell me if i am missing something to add product? how can i add product to particular category?

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Mvc;
using Nop.Admin.Models.Catalog;
using Nop.Core.Infrastructure;
using Nop.Plugin.Misc.ProductImport.Models;
using Nop.Services.Catalog;

namespace Nop.Plugin.Misc.Product.Controllers
{
    class ProductImportController : Controller
    {
        //
        // GET: /Default1/
        public void CreateProduct()
        {
            var productService = new NopEngine().Resolve<IProductService>();
            
            var prod = new Core.Domain.Catalog.Product
            {
                Name = "Test product",                
                UpdatedOnUtc = DateTime.UtcNow,
                CreatedOnUtc = DateTime.UtcNow,
            };

            productService.InsertProduct(prod);
        }
    }
}

Yes that looks like the right direction.

To map a product to a category you create a new ProductCategory and save it through the CategoryService, like this:

var productCategory = new ProductCategory
     {
        ProductId = myProduct.Id,
        Product = myProduct,
        Category = myCategory,
        CategoryId = myCategory.Id
     };

_categoryService.InsertProductCategory(productCategory);

Many thanks i really appreciate your help , ok now another thing i have MS SQL database which has a table of categories and Products, i want to fetch it from that DB and insert into nopCommerce DB, how can i achieve this?

My Controller look like this now.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web.Mvc;
using Nop.Admin.Models.Catalog;
using Nop.Core.Domain.Catalog;
using Nop.Core.Infrastructure;
using Nop.Plugin.Misc.ProductImport.Models;
using Nop.Services.Catalog;

namespace Nop.Plugin.Misc.Product.Controllers
{
    class ProductImportController : Controller
    {
        //
        // GET: /Default1/
        public void CreateProduct()
        {
            //product service
            var _productService = new NopEngine().Resolve<IProductService>();
            
            // category service
            var _categoryService = new NopEngine().Resolve<ICategoryService>();

            //declare product instance
            Core.Domain.Catalog.Product prod = new Core.Domain.Catalog.Product()
            {
                Name = "DELL 4530",
                UpdatedOnUtc = DateTime.UtcNow,
                CreatedOnUtc = DateTime.UtcNow,
            };
            
            //add product via product service
            _productService.InsertProduct(prod);

            //create category instance
            Category _category = new Category()
            {
                Name = "Laptops"
            };            

            //relate category & product
            var productCategory = new ProductCategory
            {
                ProductId = prod.Id,
                Product = prod,
                Category = _category,
                CategoryId = _category.Id
            };

            //add product category
            _categoryService.InsertProductCategory(productCategory);
        }
    }
}

Then you will have to create a data access project to access that database. I would create that in a new project separate from the noPcommerce projects. What is the purpose of this plugin? Are you exporting products from one place and importing into nopCommerce?

Can you guide me how can i do that ? i have aspstorefront database and i want to migrate its products and some related data to nopCommerce.
