You are not accessing the WC_Product_simple instance object from your custom Dropship Data Scraper plugin.
The guilty can be mostly 2 things:
- You have not installed Woocommerce.
- The plugin Dropship Data Scraper is outdated and needs changes, to handle woocommerce.
Try to include the global Woocommerce object and to enable Woocommerce support in your plugin.
To create a product programmatically using CRUD methods introduced in Woocommerce 3 here is the correct way to make it work.
If you need to handle product attributes creation or product variations creation, refer to:
All product attributes and their term values need to be created before. Same thing for product categories and product tags.
1) The code functions:
// Custom function for product creation (For Woocommerce 3+ only)
function create_product( $args ){
if( ! function_exists('wc_get_product_object_type') && ! function_exists('wc_prepare_product_attributes') )
return false;
// Get an empty instance of the product object (defining it's type)
$product = wc_get_product_object_type( $args['type'] );
if( ! $product )
return false;
// Product name (Title) and slug
$product->set_name( $args['name'] ); // Name (title).
if( isset( $args['slug'] ) )
$product->set_name( $args['slug'] );
// Description and short description:
$product->set_description( $args['description'] );
$product->set_short_description( $args['short_description'] );
// Status ('publish', 'pending', 'draft' or 'trash')
$product->set_status( isset($args['status']) ? $args['status'] : 'publish' );
// Visibility ('hidden', 'visible', 'search' or 'catalog')
$product->set_catalog_visibility( isset($args['visibility']) ? $args['visibility'] : 'visible' );
// Featured (boolean)
$product->set_featured( isset($args['featured']) ? $args['featured'] : false );
// Virtual (boolean)
$product->set_virtual( isset($args['virtual']) ? $args['virtual'] : false );
// Prices
$product->set_regular_price( $args['regular_price'] );
$product->set_sale_price( isset( $args['sale_price'] ) ? $args['sale_price'] : '' );
$product->set_price( isset( $args['sale_price'] ) ? $args['sale_price'] : $args['regular_price'] );
if( isset( $args['sale_price'] ) ){
$product->set_date_on_sale_from( isset( $args['sale_from'] ) ? $args['sale_from'] : '' );
$product->set_date_on_sale_to( isset( $args['sale_to'] ) ? $args['sale_to'] : '' );
}
// Downloadable (boolean)
$product->set_downloadable( isset($args['downloadable']) ? $args['downloadable'] : false );
if( isset($args['downloadable']) && $args['downloadable'] ) {
$product->set_downloads( isset($args['downloads']) ? $args['downloads'] : array() );
$product->set_download_limit( isset($args['download_limit']) ? $args['download_limit'] : '-1' );
$product->set_download_expiry( isset($args['download_expiry']) ? $args['download_expiry'] : '-1' );
}
// Taxes
if ( get_option( 'woocommerce_calc_taxes' ) === 'yes' ) {
$product->set_tax_status( isset($args['tax_status']) ? $args['tax_status'] : 'taxable' );
$product->set_tax_class( isset($args['tax_class']) ? $args['tax_class'] : '' );
}
// SKU and Stock (Not a virtual product)
if( isset($args['virtual']) && ! $args['virtual'] ) {
$product->set_sku( isset( $args['sku'] ) ? $args['sku'] : '' );
$product->set_manage_stock( isset( $args['manage_stock'] ) ? $args['manage_stock'] : false );
$product->set_stock_status( isset( $args['stock_status'] ) ? $args['stock_status'] : 'instock' );
if( isset( $args['manage_stock'] ) && $args['manage_stock'] ) {
$product->set_stock_status( $args['stock_qty'] );
$product->set_backorders( isset( $args['backorders'] ) ? $args['backorders'] : 'no' ); // 'yes', 'no' or 'notify'
}
}
// Sold Individually
$product->set_sold_individually( isset( $args['sold_individually'] ) ? $args['sold_individually'] : false );
// Weight, dimensions and shipping class
$product->set_weight( isset( $args['weight'] ) ? $args['weight'] : '' );

$product->set_width( isset( $args['width'] ) ? $args['width'] : '' );
$product->set_height( isset( $args['height'] ) ? $args['height'] : '' );
if( isset( $args['shipping_class_id'] ) )
$product->set_shipping_class_id( $args['shipping_class_id'] );
// Upsell and Cross sell (IDs)
$product->set_upsell_ids( isset( $args['upsells'] ) ? $args['upsells'] : '' );
$product->set_cross_sell_ids( isset( $args['cross_sells'] ) ? $args['upsells'] : '' );
// Attributes et default attributes
if( isset( $args['attributes'] ) )
$product->set_attributes( wc_prepare_product_attributes($args['attributes']) );
if( isset( $args['default_attributes'] ) )
$product->set_default_attributes( $args['default_attributes'] ); // Needs a special formatting
// Reviews, purchase note and menu order
$product->set_reviews_allowed( isset( $args['reviews'] ) ? $args['reviews'] : false );
$product->set_purchase_note( isset( $args['note'] ) ? $args['note'] : '' );
if( isset( $args['menu_order'] ) )
$product->set_menu_order( $args['menu_order'] );
// Product categories and Tags
if( isset( $args['category_ids'] ) )
$product->set_category_ids( $args['category_ids'] );
if( isset( $args['tag_ids'] ) )
$product->set_tag_ids( $args['tag_ids'] );
// Images and Gallery
$product->set_image_id( isset( $args['image_id'] ) ? $args['image_id'] : "" );
$product->set_gallery_image_ids( isset( $args['gallery_ids'] ) ? $args['gallery_ids'] : array() );
## --- SAVE PRODUCT --- ##
$product_id = $product->save();
return $product_id;
}
// Utility function that returns the correct product object instance
function wc_get_product_object_type( $type ) {
// Get an instance of the WC_Product object (depending on his type)
if( isset($args['type']) && $args['type'] === 'variable' ){
$product = new WC_Product_Variable();
} elseif( isset($args['type']) && $args['type'] === 'grouped' ){
$product = new WC_Product_Grouped();
} elseif( isset($args['type']) && $args['type'] === 'external' ){
$product = new WC_Product_External();
} else {
$product = new WC_Product_Simple(); // "simple" By default
}
if( ! is_a( $product, 'WC_Product' ) )
return false;
else
return $product;
}
// Utility function that prepare product attributes before saving
function wc_prepare_product_attributes( $attributes ){
global $woocommerce;
$data = array();
$position = 0;
foreach( $attributes as $taxonomy => $values ){
if( ! taxonomy_exists( $taxonomy ) )
continue;
// Get an instance of the WC_Product_Attribute Object
$attribute = new WC_Product_Attribute();
$term_ids = array();
// Loop through the term names
foreach( $values['term_names'] as $term_name ){
if( term_exists( $term_name, $taxonomy ) )
// Get and set the term ID in the array from the term name
$term_ids[] = get_term_by( 'name', $term_name, $taxonomy )->term_id;
else
continue;
}
$taxonomy_id = wc_attribute_taxonomy_id_by_name( $taxonomy ); // Get taxonomy ID
$attribute->set_id( $taxonomy_id );
$attribute->set_name( $taxonomy );
$attribute->set_options( $term_ids );
$attribute->set_position( $position );
$attribute->set_visible( $values['is_visible'] );
$attribute->set_variation( $values['for_variation'] );
$data[$taxonomy] = $attribute; // Set in an array
$position++; // Increase position
}
return $data;
}
2) USAGE: - Example for a simple product creation with 2 product attributes "Color" and "Size":
$product_id = create_product( array(
'type' => '', // Simple product by default
'name' => __("The product title", "woocommerce"),
'description' => __("The product description…", "woocommerce"),
'short_description' => __("The product short description…", "woocommerce"),
// 'sku' => '',
'regular_price' => '5.00', // product price
// 'sale_price' => '',
'reviews_allowed' => true,
'attributes' => array(
// Taxonomy and term name values
'pa_color' => array(
'term_names' => array('Red', 'Blue'),
'is_visible' => true,
'for_variation' => false,
),
'pa_size' => array(
'term_names' => array('X Large'),
'is_visible' => true,
'for_variation' => false,
),
),
) );
// Displaying the created product ID
echo $product_id;
Tested and works using only Woocommerce 3 CRUD methods.
