php - getAllowAttributes this Returning NULL - Magento

Question

I'm having a problem when I try to get the attributes of the product but only returns me NULL.

I'm trying the following:

<? php
require 'app/Mage.php';
$app = Mage::app('default');

  try {
     $id = '4';
     $product = Mage::getModel('catalog/product')->load($id);
     $_attributes = $product->getAllowAttributes();

     var_dump($_attributes);

   } Catch(Exception $e){
     echo $e->getMessage();
   }

?>

I do not know if my product is lacking in something, if you really have to have something in the configurable product, please let me know what you should have.

Thank you

产品模型中没有这种方法。所以getAllowAttributes总是返回 null 除非你有一个属性被调用allow_attribtues或者你在调用你的方法之前调用它：$product->setAllowAttributes('something')。
如果您正在寻找一种方法来获取构建可配置产品所允许的属性，这就是您所需要的：

$attributes = $product->getTypeInstance(true)->getConfigurableAttributes($product);
