类别列表在类别页面上不起作用 - Magento

Question

首先，我是 Magento 的新手，所以如果您能帮忙，请详细解释一下。

我使用了以下代码：

  <div class="left-nav-inner">  
    <h3 id="products">Products</h3>
    <h4>Shop by:</h4>
    <ul id="product-menu">

<?php
/* Get the categories that are active for the store */
$_main_categories=$this->getStoreCategories();

/* Get the current category the user is in */
$_current_category=$this->getCurrentCategory();

/* Get the current category path */
$_categorypath = $this->getCurrentCategoryPath();
?>
<?php
if ($_main_categories):
    /* This bit cycles through the categories - setting the next one to current */
    foreach ($_main_categories as $_main_category):
      if($_main_category->getIsActive()):                             
           $cur_category=Mage::getModel('catalog/category')->load($_main_category->getId());
           $layer = Mage::getSingleton('catalog/layer');
           $layer->setCurrentCategory($cur_category);     

/* Write the main categories */           
?>                
<li><a href="<?php echo $this->getCurrentCategory()->getUrl()?>"><?php echo $this->getCurrentCategory()->getName();?></a></li>   


<?php 

/* Check the category variable loop against the current category path if it is - print sub categories */
if (in_array($this->getCurrentCategory()->getId(), $_categorypath)): ?>
<?php $_maincategorylisting=$this->getCurrentCategory()?>                        
<?php $_categories=$this->getCurrentChildCategories()?>
<?php if($_categories->count()):?>


<?php /* This resets the category back to the original pages category
****     If this is not done, subsequent calls on the same page will use the last category
****    in the foreach loop
*/   ?>
<?php $layer->setCurrentCategory($_current_category);  ?> 
<?php endif; ?>   

<?php endif; ?>                                   

<?php         
endif;
endforeach; 
else:
?>
<p>$_main_categories array was empty.</p>
<p>This might be because you are referencing this phtml file with a wrong type attribute. You should use <block type="catalog/navigation" ... /> !</p>
<?php endif; ?>
</div>

这会根据需要在左侧菜单上显示列表，但是当我单击类别网址时，类别页面将不会显示产品。

如果删除以下内容中的左侧列，我可以显示产品：

app/ design/frontend/default/default/layout/catalog.xml

我使用以下代码执行此操作：

---

类别默认布局

---

<catalog_category_default translate="label">
    <label>Catalog Category (Non-Anchor)</label>
    <remove name="left" />

如您所见，我添加了“删除名称=左”。

我需要在网站的每个页面上显示左侧菜单和类别，并且我需要在单击类别时显示产品...

请帮助。

看起来您在 endforeach 之后缺少 标记。

看一下你的 html 源代码。您可能会发现所有内容都在页面中，只是嵌套在

标记内，因此浏览器不会呈现它。

如果我是对的，这应该会为您显示内容（请注意末尾附近的 标签）：

 <div class="left-nav-inner">  
    <h3 id="products">Products</h3>
    <h4>Shop by:</h4>
    <ul id="product-menu">

<?php
/* Get the categories that are active for the store */
$_main_categories=$this->getStoreCategories();

/* Get the current category the user is in */
$_current_category=$this->getCurrentCategory();

/* Get the current category path */
$_categorypath = $this->getCurrentCategoryPath();
?>
<?php
if ($_main_categories):
    /* This bit cycles through the categories - setting the next one to current */
    foreach ($_main_categories as $_main_category):
      if($_main_category->getIsActive()):                             
           $cur_category=Mage::getModel('catalog/category')->load($_main_category->getId());
           $layer = Mage::getSingleton('catalog/layer');
           $layer->setCurrentCategory($cur_category);     

/* Write the main categories */           
?>                
<li><a href="<?php echo $this->getCurrentCategory()->getUrl()?>"><?php echo $this->getCurrentCategory()->getName();?></a></li>   


<?php 

/* Check the category variable loop against the current category path if it is - print sub categories */
if (in_array($this->getCurrentCategory()->getId(), $_categorypath)): ?>
<?php $_maincategorylisting=$this->getCurrentCategory()?>                        
<?php $_categories=$this->getCurrentChildCategories()?>
<?php if($_categories->count()):?>


<?php /* This resets the category back to the original pages category
****     If this is not done, subsequent calls on the same page will use the last category
****    in the foreach loop
*/   ?>
<?php $layer->setCurrentCategory($_current_category);  ?> 
<?php endif; ?>   

<?php endif; ?>                                   

<?php         
endif;
endforeach; 
?>
</ul><!-- See what I did here? -->
<?php
else:
?>

<p>$_main_categories array was empty.</p>
<p>This might be because you are referencing this phtml file with a wrong type attribute. You should use <block type="catalog/navigation" ... /> !</p>
<?php endif; ?>
</div>

我建议您使用 Alan Storm 的 Layoutviewer 来调试目标 url 上发生的情况。您可以从本文下载它，请注意，您需要创建自己的模块声明 xml 以插入到 < code>app/etc/modules 用于要激活的模块。

转到管理->cms->页面->主页->设计->自定义设计->添加此代码

<reference name="left">
    <block type="catalog/navigation" name="catalog.leftnav" after="currency" template="catalog/navigation/left.phtml"/>
</reference>
