Question

I want to add product in magneto grammatically.My code to save product is below:-

       $product = Mage::getModel('catalog/product');
        $product
        ->setAttributeSetId(4)
        ->setTypeId('simple')
        ->setCreatedAt(strtotime('now'))
        ->setSku($product_sku)
        ->setName($product_name)
        ->setWeight($product_weight)
        ->setStatus($Status)
        ->setTaxClassId(2)
        ->setManufacturer($product_manufacturer) 
        ->setCountryOfManufacture('US')
        ->setPrice($product_price)
        ->setCost($product_price)
        ->setSpecialFromDate(strtotime('now'))
        ->setSpecialToDate() */
        ->setMsrpEnabled(4)
        ->setMsrpDisplayActualPriceType(4)
        ->setMsrp($wholesale_price)
        ->setDescription($product_short_desc)
        ->setShortDescription($product_short_desc)
        ->setVisibility(4);

        $mediaArray = array(
            'thumbnail' => $imgpath,
            //'small_image' => $imagepath,
            // 'image'       => $imagepath,
        );

        $product->setStockData(array(
                'use_config_manage_stock' => 1, //'Use config settings' checkbox
                'manage_stock' => 1, //manage stock
                'min_sale_qty' => 1, //Minimum Qty Allowed in Shopping Cart
                'max_sale_qty' => 200, //Maximum Qty Allowed in Shopping Cart
                'is_in_stock' => 1, //Stock Availability
                'qty' => $product_quantity //qty
            )
        )
        ->setCategoryIds($categories); //assign product to categories

       if ($product->save()) 
        {
            $_product = Mage::getModel('catalog/product')
            ->loadByAttribute('sku', $product_sku);
            echo 'Added successfully';
        }
    }

After executing the above code,I got the following error:-

Answer 1

I got the answer:- I set the category id by using

    ->setCategoryIds($categories); //assign product to categories

And now I used

    ->setCategoryIds(array($categories)); //assign product to categories

where $categories = '2,3,5';
