Question

有人可以帮我解决以下问题吗？我们在以下代码中显示产品所属的类别列表（我们使用的类别属性是＆＃34; creareseo_heading＆＃34;）。但是，有时＆＃34; creareseo_heading＆＃34;属性为空但行仍显示带有标签但没有值。我相信我们需要一些＆＃34; if＆＃34;语句完全隐藏行。我尝试了一切，但无法使其发挥作用。基本上，如果＆＃34; creareseo_heading＆＃34;的列表，我需要该行完全消失。类别属性为空。

解决!!!见下文:)）

    $catCollection = Mage::getResourceModel('catalog/category_collection')
    ->addAttributeToSelect('*')
    ->addAttributeToFilter('entity_id', $currentCatIds)
    ->addAttributeToFilter('is_active', 1)
    ->setOrder('creareseo_heading', 'asc')
    ->addIsActiveFilter();

这对于评论来说太长了，所以添加另一个答案以适应它来帮助您调试问题......

是否报告了任何错误？如果您了解代码，也许您可以逐步更改代码并查看是否获得了预期的结果。如果您不是，那么我建议您首先将此代码块添加到原始代码中，就在我们正在谈论的<tr>块上方...

        <?php
            /* Build list with no empty values */
            $applicationGuides = array();
            foreach($catCollection as $cat){
                $c = $cat->getCreareseoHeading();
                if (!empty($c)) $applicationGuides[] = $c;
            }
            var_dump($applicationGuides);
        ?>

隐藏类别标题属性，如果它在Magento中为空
