我在WooCommerce版本3+中创建了一个变量产品(“父”产品)。从WordPress插件,我想以编程方式创建具有新属性值的产品变体(“儿童”产品)。
变体属性已在WooCommerce中设置。 因此,每次创建一个变体时,新属性的值也应该以编程方式创建,并在父变量产品中设置。
如何才能做到这一点?可能吗?
更新:我已经编写了更多我想要的代码行,并尝试了很多东西来解决它,使用woocommerce对象,并使用WordPress数据库在数据库中添加了关于术语,termmeta,术语与post之间关系的缺失数据对象 - 但没有什么能够让它发挥作用。而且我无法确定错误的地方 - 这就是为什么我无法提供更窄的问题 - 堆栈流更多的事情。
2018年9月更新:处理分类法的创建(感谢Carl F. Corneil)
从定义的变量产品ID您将在下面找到一个自定义函数,它将添加(创建)产品变体。可变父产品需要为其设置所需的属性。
您需要提供以下信息:
该数据必须存储在格式化的多维数组中(参见最后的示例)。
此函数将检查属性值(术语名称)是否已存在,如果不存在: - 它为product属性创建它 - 在父变量product中设置它。
自定义功能代码:
/**
* Create a product variation for a defined variable product ID.
*
* @since 3.0.0
* @param int $product_id | Post ID of the product parent variable product.
* @param array $variation_data | The data to insert in the product.
*/
function create_product_variation( $product_id, $variation_data ){
// Get the Variable product object (parent)
$product = wc_get_product($product_id);
$variation_post = array(
'post_title' => $product->get_title(),
'post_name' => 'product-'.$product_id.'-variation',
'post_status' => 'publish',
'post_parent' => $product_id,
'post_type' => 'product_variation',
'guid' => $product->get_permalink()
);
// Creating the product variation
$variation_id = wp_insert_post( $variation_post );
// Get an instance of the WC_Product_Variation object
$variation = new WC_Product_Variation( $variation_id );
// Iterating through the variations attributes
foreach ($variation_data['attributes'] as $attribute => $term_name )
{
$taxonomy = 'pa_'.$attribute; // The attribute taxonomy
// If taxonomy doesn't exists we create it (Thanks to Carl F. Corneil)
if( ! taxonomy_exists( $taxonomy ) ){
register_taxonomy(
$taxonomy,
'product_variation',
array(
'hierarchical' => false,
'label' => ucfirst( $attribute ),
'query_var' => true,
'rewrite' => array( 'slug' => sanitize_title($attribute) ), // The base slug
),
);
}
// Check if the Term name exist and if not we create it.
if( ! term_exists( $term_name, $taxonomy ) )
wp_insert_term( $term_name, $taxonomy ); // Create the term
$term_slug = get_term_by('name', $term_name, $taxonomy )->slug; // Get the term slug
// Get the post Terms names from the parent variable product.
$post_term_names = wp_get_post_terms( $product_id, $taxonomy, array('fields' => 'names') );
// Check if the post term exist and if not we set it in the parent variable product.
if( ! in_array( $term_name, $post_term_names ) )
wp_set_post_terms( $product_id, $term_name, $taxonomy, true );
// Set/save the attribute data in the product variation
update_post_meta( $variation_id, 'attribute_'.$taxonomy, $term_slug );
}
## Set/save all other data
// SKU
if( ! empty( $variation_data['sku'] ) )
$variation->set_sku( $variation_data['sku'] );
// Prices
if( empty( $variation_data['sale_price'] ) ){
$variation->set_price( $variation_data['regular_price'] );
} else {
$variation->set_price( $variation_data['sale_price'] );
$variation->set_sale_price( $variation_data['sale_price'] );
}
$variation->set_regular_price( $variation_data['regular_price'] );
// Stock
if( ! empty($variation_data['stock_qty']) ){
$variation->set_stock_quantity( $variation_data['stock_qty'] );
$variation->set_manage_stock(true);
$variation->set_stock_status('');
} else {
$variation->set_manage_stock(false);
}
$variation->set_weight(''); // weight (reseting)
$variation->save(); // Save the data
}
代码放在活动子主题(或主题)的function.php文件中,或者放在任何插件文件中。
用法(具有2个属性的示例):
$parent_id = 746; // Or get the variable product id dynamically
// The variation data
$variation_data = array(
'attributes' => array(
'size' => 'M',
'color' => 'Green',
),
'sku' => '',
'regular_price' => '22.00',
'sale_price' => '',
'stock_qty' => 10,
);
// The function to be run
create_product_variation( $parent_id, $variation_data );
经过测试和工作。

扩展LoicTheAztec的答案,您可以检查属性组合是否存在以及对其代码的以下修改。
function create_update_product_variation( $product_id, $variation_data ){
if(isset($variation_data['variation_id'])) {
$variation_id = $variation_data['variation_id'];
} else {
// if the variation doesn't exist then create it
// Get the Variable product object (parent)
$product = wc_get_product($product_id);
$variation_post = array(
'post_title' => $product->get_title(),
'post_name' => 'product-'.$product_id.'-variation',
'post_status' => 'publish',
'post_parent' => $product_id,
'post_type' => 'product_variation',
'guid' => $product->get_permalink()
);
// Creating the product variation
$variation_id = wp_insert_post( $variation_post );
}
// ...
}
用法示例
// The variation data
$variation_data = array(
'attributes' => array(
'size' => 'M',
'color' => 'Green',
),
'sku' => '',
'regular_price' => '22.00',
'sale_price' => '1',
'stock_qty' => 1,
);
// check if variation exists
$meta_query = array();
foreach ($variation_data['attributes'] as $key => $value) {
$meta_query[] = array(
'key' => 'attribute_pa_' . $key,
'value' => $value
);
}
$variation_post = get_posts(array(
'post_type' => 'product_variation',
'numberposts' => 1,
'post_parent' => $parent_id,
'meta_query' => $meta_query
));
if($variation_post) {
$variation_data['variation_id'] = $variation_post[0]->ID;
}
create_update_product_variation( $product_id, $variation_data );
如果产品的分类未事先在其他地方注册,则可能会遇到问题。如果你想确保分类存在,你可以为LoicTheAztec的答案添加一个条件。
像这样的东西。
foreach ($variation_data['attributes'] as $attribute => $term_name )
{
//echo 'attribute ' . $attribute . ' term name ' . $term_name;
$taxonomy = 'pa_' . $attribute; // The attribute taxonomy
// Check if the Taxonomy exists, and if not we create it.
if (! taxonomy_exists($taxonomy)){
register_taxonomy(
$taxonomy, //The name of the taxonomy. Name should be in slug form (must not contain capital letters or spaces).
'product', //post type name
array(
'hierarchical' => false,
'label' => ucfirst($taxonomy), //Display name
'query_var' => true,
'rewrite' => array(
'slug' => $taxonomy, // This controls the base slug that will display before each term
'with_front' => false // Don't display the category base before
),
)
);
}
...
我只是想把它扔出去,因为我无法使上述任何一个例子起作用。不要问我为什么其他人似乎有成功。所以,我采用了极简主义的方法,试图找出产品属性+变化的基本要素(通过在wp中手动创建并查看数据库)并想出了这个。
$article_name = 'Test';
$post_id = wp_insert_post( array(
'post_author' => 1,
'post_title' => $article_name,
'post_content' => 'Lorem ipsum',
'post_status' => 'publish',
'post_type' => "product",
) );
wp_set_object_terms( $post_id, 'variable', 'product_type' );
$attr_label = 'Test attribute';
$attr_slug = sanitize_title($attr_label);
$attributes_array[$attr_slug] = array(
'name' => $attr_label,
'value' => 'alternative 1 | alternative 2',
'is_visible' => '1',
'is_variation' => '1',
'is_taxonomy' => '0' // for some reason, this is really important
);
update_post_meta( $post_id, '_product_attributes', $attributes_array );
$parent_id = $post_id;
$variation = array(
'post_title' => $article_name . ' (variation)',
'post_content' => '',
'post_status' => 'publish',
'post_parent' => $parent_id,
'post_type' => 'product_variation'
);
$variation_id = wp_insert_post( $variation );
update_post_meta( $variation_id, '_regular_price', 2 );
update_post_meta( $variation_id, '_price', 2 );
update_post_meta( $variation_id, '_stock_qty', 10 );
update_post_meta( $variation_id, 'attribute_' . $attr_slug, 'alternative 1' );
WC_Product_Variable::sync( $parent_id );
$variation_id = wp_insert_post( $variation );
update_post_meta( $variation_id, '_regular_price', 2 );
update_post_meta( $variation_id, '_price', 2 );
update_post_meta( $variation_id, '_stock_qty', 10 );
update_post_meta( $variation_id, 'attribute_' . $attr_slug, 'alternative 2' );
WC_Product_Variable::sync( $parent_id );
这不是使用全局产品属性,而是使用特定于文章的属性。希望它可以帮助某人,因为我准备好在我开始工作之前撕掉我的头发。
如果你想在WooCommerce中生成用于测试的产品,你可以使用由WooCommerce自己制作的WooCommerce Smooth Generator。
https://github.com/woocommerce/wc-smooth-generator
例:
// Generate WC_Product object and save it to database
// 70% change generated product is simple
// 30% chance generated product is variable
$product = \WC\SmoothGenerator\Generator\Product::generate();
// Returns WC_Product object of Simple product and don't save it to database
$product = \WC\SmoothGenerator\Generator\Product::generate_simple_product();
// Returns WC_Product object of Variable Product and saves it to database
$variable_product = \WC\SmoothGenerator\Generator\Product::generate_variable_product();
Src:https://github.com/woocommerce/wc-smooth-generator/blob/master/includes/Generator/Product.php
如果您想以编程方式创建产品,可以根据需要使用Product类。
它工作但需要一些修正(函数数组中有2个逗号),我确实根据自己的需要编辑了一些代码。
(致力于wp 4.9 | wc 3.5)
首先,产品需要已经创建并关联的属性,我的分类是“pa_r”友好名称“R”backend attribute associeated img
具有校正功能
function create_product_variation( $product_id, $variation_data ){
// Get the Variable product object (parent)
$product = wc_get_product($product_id);
$variation_post = array(
'post_title' => $product->get_title(),
'post_name' => 'product-'.$product_id.'-variation',
'post_status' => 'publish',
'post_parent' => $product_id,
'post_type' => 'product_variation',
'guid' => $product->get_permalink()
);
// Creating the product variation
$variation_id = wp_insert_post( $variation_post );
// Get an instance of the WC_Product_Variation object
$variation = new WC_Product_Variation( $variation_id );
// Iterating through the variations attributes
foreach ($variation_data['attributes'] as $attribute => $term_name )
{
$taxonomy = 'pa_'.$attribute; // The attribute taxonomy
// If taxonomy doesn't exists we create it (Thanks to Carl F. Corneil)
if( ! taxonomy_exists( $taxonomy ) ){
register_taxonomy(
$taxonomy,
'product_variation',
array(
'hierarchical' => false,
'label' => ucfirst( $taxonomy ),
'query_var' => true,
'rewrite' => array( 'slug' => '$taxonomy') // The base slug
)
);
}
// Check if the Term name exist and if not we create it.
if( ! term_exists( $term_name, $taxonomy ) )
wp_insert_term( $term_name, $taxonomy ); // Create the term
$term_slug = get_term_by('name', $term_name, $taxonomy )->slug; // Get the term slug
// Get the post Terms names from the parent variable product.
$post_term_names = wp_get_post_terms( $product_id, $taxonomy, array('fields' => 'names') );
// Check if the post term exist and if not we set it in the parent variable product.
if( ! in_array( $term_name, $post_term_names ) )
wp_set_post_terms( $product_id, $term_name, $taxonomy, true );
// Set/save the attribute data in the product variation
update_post_meta( $variation_id, 'attribute_'.$taxonomy, $term_slug );
}
## Set/save all other data
// SKU
if( ! empty( $variation_data['sku'] ) )
$variation->set_sku( $variation_data['sku'] );
// Prices
if( empty( $variation_data['sale_price'] ) ){
$variation->set_price( $variation_data['regular_price'] );
} else {
$variation->set_price( $variation_data['sale_price'] );
$variation->set_sale_price( $variation_data['sale_price'] );
}
$variation->set_regular_price( $variation_data['regular_price'] );
// Stock
if( ! empty($variation_data['stock_qty']) ){
$variation->set_stock_quantity( $variation_data['stock_qty'] );
$variation->set_manage_stock(true);
$variation->set_stock_status('');
} else {
$variation->set_manage_stock(false);
}
$variation->set_weight(''); // weight (reseting)
$variation->save(); // Save the data
}
我用变量[id_post,attribute,sku,regular_price,stock]中我需要的数据制作了一个数组
$hijos = array(
[9623,'265/70 R16','NE-CT-CO-USA-016-005','0',53],
[9624,'235/65 R17','NE-AU-CO-EUR-017-050','189000',56]
);
和foreach动态创建我的产品的所有变化
foreach ($hijos as $vari) {
// The variation data
$variation_data = array(
'attributes' => array(
'r' => $vari[1],
),
'sku' => $vari[2],
'regular_price' => str_replace('.', '', $vari[3]),
'stock_qty' => $vari[4]
);
// var_dump($variation_data);
create_product_variation( $vari[0], $variation_data );
}
