将具有值的产品属性添加到 Woocommerce 中的产品

我正在使用此代码添加自定义属性

$attributes = array(
    array("name"=>"Size","options"=>array("S","L","XL","XXL"),"position"=>1,"visible"=>1,"variation"=>1),
    array("name"=>"Color","options"=>array("Red","Blue","Black","White"),"position"=>2,"visible"=>1,"variation"=>1)
);
if($attributes){
    $productAttributes=array();
    foreach($attributes as $attribute){
        $attr = wc_sanitize_taxonomy_name(stripslashes($attribute["name"])); // remove any unwanted chars and return the valid string for taxonomy name
        $attr = 'pa_'.$attr; // woocommerce prepend pa_ to each attribute name
        if($attribute["options"]){
            foreach($attribute["options"] as $option){
                wp_set_object_terms($product_id,$option,$attr,true); // save the possible option value for the attribute which will be used for variation later
            }
        }
        $productAttributes[sanitize_title($attr)] = array(
            'name' => sanitize_title($attr),
            'value' => $attribute["options"],
            'position' => $attribute["position"],
            'is_visible' => $attribute["visible"],
            'is_variation' => $attribute["variation"],
            'is_taxonomy' => '1'
        );
    }
    update_post_meta(11874,'_product_attributes',$productAttributes); // save the meta entry for product attributes

这段代码的结果我只添加了产品属性名称，没有术语值...

我对此进行了很多搜索，但没有得到任何答案。

您的代码中有一些错误。您的主要错误：保存为产品元数据（最后）的属性术语需要是术语 ID 数组 （而不是术语名称）.

尝试以下重新访问的代码：

$product_id = 11874;

$attributes_data = array(
    array('name'=>'Size',  'options'=>array('S', 'L', 'XL', 'XXL'), 'visible' => 1, 'variation' => 1 ),
    array('name'=>'Color', 'options'=>array('Red', 'Blue', 'Black', 'White'), 'visible' => 1, 'variation' => 1 )
);

if( sizeof($attributes_data) > 0 ){
    $attributes = array(); // Initializing

    // Loop through defined attribute data
    foreach( $attributes_data as $key => $attribute_array ) {
        if( isset($attribute_array['name']) && isset($attribute_array['options']) ){
            // Clean attribute name to get the taxonomy
            $taxonomy = 'pa_' . wc_sanitize_taxonomy_name( $attribute_array['name'] );

            $option_term_ids = array(); // Initializing

            // Loop through defined attribute data options (terms values)
            foreach( $attribute_array['options'] as $option ){
                if( term_exists( $option, $taxonomy ) ){
                    // Save the possible option value for the attribute which will be used for variation later
                    wp_set_object_terms( $product_id, $option, $taxonomy, true );
                    // Get the term ID
                    $option_term_ids[] = get_term_by( 'name', $option, $taxonomy )->term_id;
                }
            }
        }
        // Loop through defined attribute data
        $attributes[$taxonomy] = array(
            'name'          => $taxonomy,
            'value'         => $option_term_ids, // Need to be term IDs
            'position'      => $key + 1,
            'is_visible'    => $attribute_array['visible'],
            'is_variation'  => $attribute_array['variation'],
            'is_taxonomy'   => '1'
        );
    }
    // Save the meta entry for product attributes
    update_post_meta( $product_id, '_product_attributes', $attributes );
}

经过测试并有效。

Note:需要定义所有产品属性及其值（用你的实际代码）
