在 Woocommerce 中将产品类别转换为产品属性
Convert product categories to product attributes in Woocommerce
在 Woocommerce 中,我尝试使用以下代码将产品类别转换为产品属性:
$all_categories = wp_get_post_terms( get_the_ID(), 'product_cat' );;
$productid = get_the_ID();
foreach ($all_categories as $_term) {
//$_term->name
// $_term->parent
$parent = get_term_by( 'id', $_term->parent, 'product_cat');
// echo $parent->name . ': ' . $_term->name . '<br />';
$attribute_name = $parent->name; //slug of the attribute(taxonomy)
$attribute_value = $_term->name; //slug of the attribute value (term)
//Appending term to the object/product.
$term_taxonomy_ids = wp_set_object_terms(get_the_ID(), $attribute_value, $attribute_name, true);
$data = array(
$attribute_name => array(
'name' => wc_clean($attribute_name),
'value' => $attribute_value,
'is_visible' => '1',
'is_variation' => '1',
'is_taxonomy' => '0' // i tried with 1
)
);
// getting the Post Meta
$_product_attributes = get_post_meta($productid, '_product_attributes', TRUE);
if ( is_array($_product_attributes) ){
} else {
$_product_attributes = array();
}
//Updating the Post Meta
update_post_meta($productid, '_product_attributes', array_merge($_product_attributes, $data));
}
部分工作 因为我需要在后端产品 > 属性中查看列出的转换属性...
这是完成此操作的完整且正确的方法......它部分基于
1) 需要前两个实用程序函数才能使其工作:
/**
* Utility function: 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 = $wpdb->get_var("SELECT attribute_id
FROM {$wpdb->prefix}woocommerce_attribute_taxonomies
WHERE attribute_name LIKE '$name'");
return $attribute_id;
}
/**
* Utility function: 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 );
if( $set ){
$attributes = wc_get_attribute_taxonomies();
$args['attribute_id'] = get_attribute_id_from_name( $name );
$attributes[] = (object) $args;
set_transient( 'wc_attribute_taxonomies', $attributes );
} else {
return;
}
}

2) 现在你重新访问的代码,插入一个带有一个可选参数的函数(产品 ID):
function create_attributtes_from_categories( $product_id = 0 ){
$product_id = $product_id == 0 ? get_the_ID() : $product_id;
$taxonomy = 'product_cat';
$product_categories = wp_get_post_terms( $product_id, $taxonomy );
$product_categories_data = $product_cats = $product_attributes = array();
// 1. Get and process product categories from a product
if( sizeof($product_categories) > 0 ){
// 1st Loop get parent/child categories pairs
foreach ( $product_categories as $product_category ) {
$term_name = $product_category->name; // Category name
// keep product categories that have parent category
if( $product_category->parent > 0 ){
$parent_name = get_term_by( 'id', $product_category->parent, $taxonomy)->name; // Parent category name
// Set them in the array
$product_categories_data[$parent_name] = $term_name;
}
}
// 2nd Loop: The get missing categories (the last child category or a unique category) and assign an temporary value to it
foreach ( $product_categories as $product_category ) {
if( ! in_array($product_category->name, array_keys($product_categories_data) ) ){
// Assign an temporary value for the category name in the array of values
$product_categories_data[$product_category->name] = 'Temp';
}
}
}
// 2. create and process product attributes and values from the product categories
if( sizeof($product_categories_data) > 0 ){
// Get product attributes post meta data
$existing_data_attributes = (array) get_post_meta( $product_id, '_product_attributes', true );
// Get the position
if( sizeof($existing_data_attributes) > 0 )
$position = sizeof($existing_data_attributes);
// Loop through our categories array
foreach ( $product_categories_data as $key_label => $value_name ) {
$taxonomy = wc_attribute_taxonomy_name($key_label);
$attr_name = wc_sanitize_taxonomy_name($key_label); // attribute slug name
// NEW Attributes: Register and save them (if it doesn't exits)
if( ! taxonomy_exists( $taxonomy ) )
save_product_attribute_from_name( $attr_name, $key_label );
// Check if the Term name exist and if not we create it.
if( ! term_exists( $value_name, $taxonomy ) ){
wp_insert_term( $value_name, $taxonomy, array('slug' => sanitize_title($value_name) ) );
// Set attribute value for the product
wp_set_post_terms( $product_id, $value_name, $taxonomy, true );
}
if( ! in_array( $taxonomy, array_keys($existing_data_attributes) ) ){
$position++;
// Setting formatted post meta data if it doesn't exist in the array
$product_attributes[$taxonomy] = array (
'name' => $taxonomy,
'value' => '',
'position' => $position,
'is_visible' => 1,
'is_variation' => 1,
'is_taxonomy' => 1
);
}
}
// Save merged data updating the product meta data
update_post_meta( $product_id, '_product_attributes', array_merge( $existing_data_attributes, $product_attributes ) );
}
}

3) 用法:
I have still a little bug to solve…
The function need to be run 2 times to set correctly the attribute terms values.
But it works and I will solve that as fast as I can.
1) 当前产品(当前产品post ID):
create_attributtes_from_categories();
create_attributtes_from_categories();
2) 对于定义的产品 ID (此处为整数):
create_attributtes_from_categories(746);
create_attributtes_from_categories(746);
3) 对于动态产品 ID,在定义了 $product_id
变量的函数内:
create_attributtes_from_categories( $product_id );
create_attributtes_from_categories( $product_id );
在 Woocommerce 中,我尝试使用以下代码将产品类别转换为产品属性:
$all_categories = wp_get_post_terms( get_the_ID(), 'product_cat' );;

foreach ($all_categories as $_term) {
//$_term->name
// $_term->parent
$parent = get_term_by( 'id', $_term->parent, 'product_cat');
// echo $parent->name . ': ' . $_term->name . '<br />';
$attribute_name = $parent->name; //slug of the attribute(taxonomy)
$attribute_value = $_term->name; //slug of the attribute value (term)
//Appending term to the object/product.
$term_taxonomy_ids = wp_set_object_terms(get_the_ID(), $attribute_value, $attribute_name, true);
$data = array(
$attribute_name => array(
'name' => wc_clean($attribute_name),
'value' => $attribute_value,
