所有Magento模型都有可用的"getData"方法，该方法将返回键/值对的php数组.在您的grouped.phtml文件顶部尝试此操作(在定义了$ _product之后)

print('<pre>');print_r($_product->getData());print('</pre>');

您应该看到类似于以下内容的输出.

Array
(
    [store_id] => 1
    [entity_id] => 3437
    [entity_type_id] => 4
    [attribute_set_id] => 27
    [type_id] => grouped
    [sku] => 
    [category_ids] => 
    [created_at] => 2009-04-16 03:37:51
...     

因此，您可以获取一系列属性，只需拔出键即可.您还可以使用Magento的便捷/魔术getX和setX方法.在所有Magento模型上，您可以通过调用基于名称驼峰大小写的方法来访问数据数组中的任何属性，

$created_at = $_product->getCreatedAt();
$_product->setCreatedAt($date);

因此，无论您的自定义属性名称是什么，您都应该可以使用上面的方法来获得它，并且如果您不确定只是print_r还是var_dump，则由getData()返回的数组的内容.

最后，如果custom属性位于相关产品之一简单产品上，您将需要更多类似的东西

$_associatedProducts[0]->getCreatedAt();

I need to find a way to show the value of a custom attribute in place of the "Product Name" shown in the image below.

_{(source: magentocommerce.com)}

I'm working with /app/design/frontend/default/defaultx/template/catalog/product/view/type/grouped.php

The code below doesn't work(the custom attribute is yearmade):

<?php if (count($_associatedProducts)): ?>  
<?php foreach ($_associatedProducts as $_item): ?>  
    <tr>  
        <td><?php echo $this->htmlEscape($_item->getYearmade()) ?></td>

Any help would be appreciated.

EDIT: So the answer turned out to be quite simple. You see what I failed to mention above was that there was indeed output... but that it was just a number (eg: 52). Turns out this was the ID for that custom attribute value (It was a Dropdown type of custom attribute).

So in summary
This works for custom attributes of type text:

echo $this->htmlEscape($_item->getYearmade())

But for all other types of custom attribute (I think), the following should be used:

echo $this->htmlEscape($_item->getAttributeText('yearmade'))

I would not have discovered this without the most excellent answer provided by Alan Storm, below. Thank you sir.

All Magento models have a "getData" method available, which will return an php-array of key/value pairs. Try this at the top of your grouped.phtml file (after $_product is defined)

print('<pre>');print_r($_product->getData());print('</pre>');

You should see output that looks something like the following.

Array
(
    [store_id] => 1
    [entity_id] => 3437
    [entity_type_id] => 4
    [attribute_set_id] => 27
    [type_id] => grouped
    [sku] => 
    [category_ids] => 
    [created_at] => 2009-04-16 03:37:51
...     

So, you can grab an array of properties and just pull the key out. You could also use Magento's convenience/magic getX and setX methods. On all Magento models, you can access any property in the data array by calling a method based on the camel case version of the name,

$created_at = $_product->getCreatedAt();
$_product->setCreatedAt($date);

So, whatever your custom attribute name is, you should be able to get at it using the above, and if you're not sure just print_r or var_dump the contents of the array returned by getData().

Finally, if the custom attribute is on one of the related products simple product, you'll wants something more like

$_associatedProducts[0]->getCreatedAt();
