我正在 Woocommerce 中制作一个插件，用于导入 json 文件并在产品页面上创建产品变体。除了为单个产品变体定义单个属性值之外，一切都有效。代码可以定义变量产品的属性及其所有属性值，但代码不能定义单个产品变体的特定属性值。代码 $variation->set_attributes($variation_attributes);似乎没有效果。相反，每个产品变体都具有由变量产品定义的所有属性值。为产品变体定义特定属性值的正确语法是什么？

这是我导入的json文件：
[

"sku": "TSHIRT001",
"description": "A stylish t-shirt",
"attributes": {
"Color": ["Red", "Blue", "Green"],
"Size": ["S", "M", "L"]
},
"variations": [
{
"sku": "TSHIRT001-RED-S",
"price": "19.99",
"attributes": {
"Color": "Red",
"Size": "S"
}
},
{
"sku": "TSHIRT001-RED-M",
"price": "19.99",
"attributes": {
"Color": "Red",
"Size": "M"
}
},
{
"sku": "TSHIRT001-BLUE-S",
"price": "19.99",
"attributes": {
"Color": "Blue",
"Size": "S"
}
}
]
},
{
"name": "Hoodie",
"sku": "HOODIE001",
"description": "A warm hoodie",
"attributes": {
"Color": ["Black", "White"],
"Size": ["M", "L", "XL"]
},
"variations": [
{
"sku": "HOODIE001-BLACK-M",
"price": "29.99",
"attributes": {
"Color": "Black",
"Size": "M"
}
},
{
"sku": "HOODIE001-BLACK-L",
"price": "29.99",
"attributes": {
"Color": "Black",
"Size": "L"
}
},
{
"sku": "HOODIE001-WHITE-XL",
"price": "29.99",
"attributes": {
"Color": "White",
"Size": "XL"
}
}
]
}
]
`
我找到了解决办法。对于变异属性分类法与 slug 配对（蓝色的 slug 是蓝色）
$variation_attributes = [];
foreach ($data['attributes'] as $attribute_name => $attribute_value) {
$taxonomy = 'pa_' . lcfirst($attribute_name);
$variation_attributes[$taxonomy] = lcfirst($attribute_value);
}
