在 WooCommerce 中以编程方式创建一个可变产品和两个新属性 [英] Create programmatically a variable product and two new attributes in WooCommerce
本文介绍了在 WooCommerce 中以编程方式创建一个可变产品和两个新属性的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想以编程方式创建一个具有两个新变体属性的可变产品(父"产品) - 所有这些都来自 WordPress 插件(因此没有对 API 的 HTTP 请求).
I would like to programmatically create a variable product ("parent" product) with two new variante attributes - all that from a WordPress plugin (so no HTTP Request to an API).
这两个变体属性也应该即时创建.
These two variante attributes should also be created on the fly.
这怎么办?
(使用 WooCommerce 版本 3)
(with WooCommerce version 3)
更新:我已经写了更多我希望的代码行，并尝试了很多方法来解决它，使用 wooCommerce 对象，并在数据库中添加了有关术语、termmeta、术语与帖子的关系的缺失数据，使用WordPress 数据库对象 - 但没有什么足以让它工作.而且我无法指出我哪里出错了——这就是为什么我不能提供一个更窄的问题——stackoverflow 更适合做的事情.
Update : I have written more lines of codes on this that I wished, and tried many things to solve it, using wooCommerce objects, and added missing data about terms, termmeta, the relationship from term with post, in the database using the WordPress database object - but nothing has sufficed to make it work. And I couldn't pin-point where I went wrong - that is why I couldn't provide a narrower problem - things for which stackoverflow is more made for.
推荐答案
在这里，您可以使用新的产品属性 + 值创建新的可变产品:
Here you get the way to create a new variable product with new product attributes + values:
/**
* Save a new product attribute from his name (slug).
*
* @since 3.0.0
* @param string $name | The product attribute name (slug).
* @param string $label | The product attribute label (name).
*/
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;
}
}
/**
* Get the product attribute ID from the name.
*
* @since 3.0.0
* @param string $name | The name (slug).
*/
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);
}
/**
* Create a new variable product (with new attributes if they are).
* (Needed functions:
*
* @since 3.0.0
* @param array $data | The data to insert in the product.
*/
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
}
代码位于您的活动子主题(或活动主题)的 function.php 文件中.经过测试并有效.
USAGE(具有 2 个新属性 + 值的示例):
USAGE (example with 2 new attributes + values):
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' ),
),
) );
经过测试并有效.
