在这里，您将获得创建具有新产品属性+值的新变量产品的方法：
function save_product_attribute_from_name( $name, $label='', $set=true ){ if( ! function_exists ('get_attribute_id_from_name') ) return; global $wpdb; $label = $label == '' ? ucfirst($name) : $label; $attribute_id = get_attribute_id_from_name( $name ); if( empty($attribute_id) ){ $attribute_id = NULL; } else { $set = false; } $args = array( 'attribute_id' => $attribute_id, 'attribute_name' => $name, 'attribute_label' => $label, 'attribute_type' => 'select', 'attribute_orderby' => 'menu_order', 'attribute_public' => 0, ); if( empty($attribute_id) ) { $wpdb->insert( "{$wpdb->prefix}woocommerce_attribute_taxonomies", $args ); set_transient( 'wc_attribute_taxonomies', false ); } if( $set ){ $attributes = wc_get_attribute_taxonomies(); $args['attribute_id'] = get_attribute_id_from_name( $name ); $attributes[] = (object) $args; //print_r($attributes); set_transient( 'wc_attribute_taxonomies', $attributes ); } else { return; }}function get_attribute_id_from_name( $name ){ global $wpdb; $attribute_id = $wpdb->get_col("SELECt attribute_id FROM {$wpdb->prefix}woocommerce_attribute_taxonomies WHERe attribute_name LIKE '$name'"); return reset($attribute_id);}function create_product_variation( $data ){ if( ! function_exists ('save_product_attribute_from_name') ) return; $postname = sanitize_title( $data['title'] ); $author = empty( $data['author'] ) ? '1' : $data['author']; $post_data = array( 'post_author' => $author, 'post_name' => $postname, 'post_title' => $data['title'], 'post_content' => $data['content'], 'post_excerpt' => $data['excerpt'], 'post_status' => 'publish', 'ping_status' => 'closed', 'post_type' => 'product', 'guid' => home_url( '/product/'.$postname.'/' ), ); // Creating the product (post data) $product_id = wp_insert_post( $post_data ); // Get an instance of the WC_Product_Variable object and save it $product = new WC_Product_Variable( $product_id ); $product->save(); ## ---------------------- Other optional data ---------------------- ## ## (see WC_Product and WC_Product_Variable setters methods) // THE PRICES (No prices yet as we need to create product variations) // IMAGES GALLERY if( ! empty( $data['gallery_ids'] ) && count( $data['gallery_ids'] ) > 0 ) $product->set_gallery_image_ids( $data['gallery_ids'] ); // SKU if( ! empty( $data['sku'] ) ) $product->set_sku( $data['sku'] ); // STOCK (stock will be managed in variations) $product->set_stock_quantity( $data['stock'] ); // Set a minimal stock quantity $product->set_manage_stock(true); $product->set_stock_status(''); // Tax class if( empty( $data['tax_class'] ) ) $product->set_tax_class( $data['tax_class'] ); // WEIGHT if( ! empty($data['weight']) ) $product->set_weight(''); // weight (reseting) else $product->set_weight($data['weight']); $product->validate_props(); // Check validation ## ---------------------- VARIATION ATTRIBUTES ---------------------- ## $product_attributes = array(); foreach( $data['attributes'] as $key => $terms ){ $taxonomy = wc_attribute_taxonomy_name($key); // The taxonomy slug $attr_label = ucfirst($key); // attribute label name $attr_name = ( wc_sanitize_taxonomy_name($key)); // attribute slug // NEW Attributes: Register and save them if( ! taxonomy_exists( $taxonomy ) ) save_product_attribute_from_name( $attr_name, $attr_label ); $product_attributes[$taxonomy] = array ( 'name' => $taxonomy, 'value' => '', 'position' => '', 'is_visible' => 0, 'is_variation' => 1, 'is_taxonomy' => 1 ); foreach( $terms as $value ){ $term_name = ucfirst($value); $term_slug = sanitize_title($value); // Check if the Term name exist and if not we create it. if( ! term_exists( $value, $taxonomy ) ) wp_insert_term( $term_name, $taxonomy, array('slug' => $term_slug ) ); // Create the term // Set attribute values wp_set_post_terms( $product_id, $term_name, $taxonomy, true ); } } update_post_meta( $product_id, '_product_attributes', $product_attributes ); $product->save(); // Save the data}代码进入您的活动子主题（或活动主题）的function.php文件中。 经过测试和工作。
用法 （带有2个新属性+值的示例）：
create_product_variation( array( 'author' => '', // optional 'title' => 'Woo special one', 'content' => '<p>This is the product content <br>A very nice product, soft and clear…<p>', 'excerpt' => 'The product short description…', 'regular_price' => '16', // product regular price 'sale_price' => '', // product sale price (optional) 'stock' => '10', // Set a minimal stock quantity 'image_id' => '', // optional 'gallery_ids' => array(), // optional 'sku'=> '', // optional 'tax_class' => '', // optional 'weight' => '', // optional // For NEW attributes/values use NAMES (not slugs) 'attributes' => array( 'Attribute 1' => array( 'Value 1', 'Value 2' ), 'Attribute 2' => array( 'Value 1', 'Value 2', 'Value 3' ), ),) );
