我在 WooCommerce 版本 3+ 中创建了一个可变产品（“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）。
WooCommerce 中已经设置了变体属性。
因此，每次创建一个变体时，也应以编程方式创建新属性的值并在父变量产品中设置。
如何才能做到这一点？是否可以？
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，并在使用 WordPress 数据库的数据库中添加了有关术语、术语元、术语与帖子的关系的缺失数据对象 - 但没有任何东西足以让它工作。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。
2020 年 1 月更新：更改为
WC_Product方法get_name()，而不是get_title()
2018 年 9 月更新：处理分类创建（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，该函数将添加（创建）产品变体。可变父产品需要为其设置所需的属性。
您需要提供一些信息：
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）是否已经存在，如果不存在：
自定义函数代码：
/**
* 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' => $product->get_name(),
'post_name' => 'product-'.$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
}
代码在您的活动子主题（或主题）的 function.php 文件中或任何插件文件中。
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 );
测试和工作。
第 2 部分： 在 WooCommerce 中以编程方式创建可变产品和两个新属性
你会在后端得到这个：
它将在前端完美运行。
我只是要把它扔在那里，因为我无法让上述任何例子工作。不要问我为什么其他人似乎取得了成功。所以，我采取了极简主义的方法，试图找出产品属性+变体的基本要素（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。希望它对某人有所帮助，因为我正准备在我开始工作之前把头发扯下来。
编辑：我会说只有在您无法使官方方法正常工作时才使用它。他们会随着时间改变这些东西（字段名称，例如“_regular_price”等），这样做可能不是超级未来的证明。
不知道为什么，但这些解决方案都不适合我，所以我决定创建自己的：
<?php
/**
* Create a variable product on woocommerce
* @return int Product ID
*/
function pricode_create_product(){
$product = new WC_Product_Variable();
$product->set_description('T-shirt variable description');
$product->set_name('T-shirt variable');
$product->set_sku('test-shirt');
$product->set_price(1);
$product->set_regular_price(1);
$product->set_stock_status();
return $product->save();
}
/**
* Create Product Attributes
* @param string $name Attribute name
* @param array $options Options values
* @return Object WC_Product_Attribute
*/
function pricode_create_attributes( $name, $options ){
$attribute = new WC_Product_Attribute();
$attribute->set_id(0);
$attribute->set_name($name);
$attribute->set_options($options);
$attribute->set_visible(true);
$attribute->set_variation(true);
return $attribute;
}
/**
* [pricode_create_variations description]
* @param [type] $product_id [description]
* @param [type] $values [description]
* @return [type] [description]
*/
function pricode_create_variations( $product_id, $values, $data ){
$variation = new WC_Product_Variation();
$variation->set_parent_id( $product_id );
$variation->set_attributes($values);
$variation->set_status('publish');
$variation->set_sku($data->sku);
$variation->set_price($data->price);
$variation->set_regular_price($data->price);
$variation->set_stock_status();
$variation->save();
$product = wc_get_product($product_id);
$product->save();
}
//Adding product
$product = pricode_create_product();
//Creating Attributes
$atts = [];
$atts[] = pricode_create_attributes('color',['red', 'green']);
$atts[] = pricode_create_attributes('size',['S', 'M']);
//Adding attributes to the created product
$product->set_attributes( $atts );
$product->save();
//Setting data (following Alexander's rec
$data = new stdClass();
$data->sku = 'sku-123';
$data->price = '10';
//Create variations
pricode_create_variations( $product->get_id(), ['color' => 'red', 'size' => 'M'], $data );
希望它可以帮助别人。
扩展 LoicTheAztec 的答案，您可以通过对其代码进行以下修改来检查属性组合是否存在。
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 );
}
// ...
}
示例用法
// 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 );
如果您想在 WooCommerce 中生成用于测试的产品，您可以使用WooCommerce 自己制作的WooCommerce Smooth Generator。
https://github.com/woocommerce/wc-smooth-generator
例子：
// 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();
来源：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，您可以根据需要进行产品类。
它可以工作，但需要一些更正（函数数组中的 2 个逗号），我确实根据需要编辑了一些代码。
（工作于 wp 4.9 | wc 3.5）
首先产品需要已经创建并关联属性，我的分类是“pa_r”友好名称“R” 后端属性关联img
带校正的函数
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
}
我用变体 [id_post、attribute、sku、regular_price、stock] 中需要的数据创建了一个数组
$hijos = array(
[9623,'265/70 R16','NE-CT-CO-USA-016-005','0',53],
[9624,'235/65 R17','NE-AU-CO-EUR-017-050','189000',56]
);
和 foreach 动态创建我的产品的所有变体
foreach ($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], $variation_data );
}
如果产品的分类没有事先在其他地方注册，您可能会在这里遇到问题。如果您想确保分类存在，您可以在 LoicTheAztec 的答案中添加一个条件。
像这样的东西。
foreach ($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
),
)
);
}
...
上面的答案（LoicTheAztec）帮了我很多，但有一些问题而不是使用
update_post_meta( $variation_id, 'attribute_'.$taxonomy, $term_slug );
采用 ：
update_post_meta( $variation_id, 'attribute_'.$attribute, $term_name );
因为分类法已经被修改，这会导致在更改此更新值后更新帖子元数据并且在此更改后未在管理产品变体编辑中自动选择它工作得很好！
除了Alejandro Giraldo 回答使用分类法而不是自定义产品属性之外，您还可以使用此修改后的版本
