php - 通过 WooCommerce 中的特定数据以编程方式添加产品变体

Question

我想要做的是保存一个新的变体，但是在保存它时，它会抛出一个错误 Call to a member function get_name() on string; 正在创建变体，但没有任何属性值。

public static function create_product_variants($id,$product,$variant_data){
        
        for($i=0; $i< count($variant_data); $i++){
            $variant = new WC_Product_Variation();
            $variant->set_parent_id($id);
            
            foreach($variant_data[$i] as $key => $value){
                if($key == 'attribute_name'){
                    $attribute_name = $value;
                }
                if($key == 'variant'){
                    if(gettype($value) == 'string'){
                        $variants = [$value];
                    }else{
                        $variants = $value;
                    }   
                }
            }
            if(count($variants) == count($attribute_name)){
                $variant_attributes = array();
            
                for($j=0; $j< count($variants); $j++){
                    $variant_attributes[$attribute_name[$j]] = $variants[$j];
                }
                $variant->set_attributes($variant_attributes);
            }
            $id = $variant->save();
            
        }
}

通过的数据$variant_data是这样的：

[
    {
      attribute_name: ["Color","Size"]
      price: "10"
      quantity: "20"
      variant: ["red","24"]
    }
]

$id是product_id

您的代码中存在一些复杂性和错误。而是尝试以下重新访问的代码：

public static function create_product_variants( $id, $product, $data ){
    foreach( $data as $variation_data ){
        if( isset($variation_data['attribute_name']) && isset($variation_data['variant']) ){
            $variation = new WC_Product_Variation();
            
            $variation->set_parent_id($id); // Set parent ID
            
            $variation->set_regular_price($variation_data['price']); // Set price
            $variation->set_price($variation_data['price']); // Set price
            
            // Enable and set stock
            if ( isset($variation_data['quantity']) ) {
                $variation->set_manage_stock(true);
                $variation->set_stock_quantity($variation_data['quantity']);
                $variation->set_stock_status('instock');
            }
            
            $attributes      = array(); // Initializing
            $attribute_names = (array) $variation_data['attribute_name'];
            $attribute_terms = (array) $variation_data['variant']; 
        
            // Formatting attributes data array
            foreach( $attribute_names as $key => $attribute_name ){
                $attributes[sanitize_title($attribute_name)] = $attribute_terms[$key];
            }
            
            $variation->set_attributes($attributes); // Set attributes
            $variation_id = $variation->save(); // Save to database (return the variation Id)
        }
    }
}

它应该更好地工作。

将创建/保存变体，该方法get_name()这次不应抛出任何错误。

做起来很简单

public static function create_product_variants($id,$product,$variant_data){
        
    foreach ($variant_data as $object){
        $variant = new WC_Product_Variation();
        $variant->set_parent_id($product->get_id());
        $attributes = array_combine($object->attribute_name, $object->variant)
        $variant->set_attributes($attributes);
        $variant->save();
    }
    
}

如果对象是

[
    {
      attribute_name: ["Color","Size"]
      price: "10"
      quantity: "20"
      variant: ["red","24"]
    }
]
