在WooCommerce中以编程方式创建可变产品和两个新属性 [英] Create programmatically a variable product and two new attributes in WooCommerce

问题描述

我想以编程方式创建具有两个新的variant属性的变量产品(父"产品)，这些属性全部来自WordPress插件(因此无需HTTP请求API).

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variant属性也应该动态创建.

These two variante attributes should also be created on the fly.

这怎么办?

(WooCommerce版本3)

(with WooCommerce version 3)

更新:我已经在上面写了我希望的更多行代码，并使用wooCommerce对象尝试了许多方法来解决它，并在数据库中使用了有关术语，termmeta，term与post之间的关系的缺失数据WordPress数据库对象-但没有任何措施足以使其正常工作.而且我无法指出我出了错的地方-这就是为什么我不能提供一个更狭窄的问题-专门针对stackoverflow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

之后::在这里，您可以使用新的产品属性+值来创建新的变量产品:

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
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试并可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.

用法(带有2个新属性和值的示例):

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，可以正常工作.

Tested and works.
