How to Fix: Show Sub-Category on Category page

Question

I'm having issues with my coding, I'm trying to show my category's sub-categories thumbnails on the category page in all categoies.

The problem is that it's showing the same sub-category on different categories instead of just showing it into only its parent category.

CMS Block:

{{block type="core/template" template="subcategories.phtml" }}

.PHTML File:

<div class="clearfix title-container product-slider-container"></div>
<?php
$category = Mage::getSingleton('catalog/layer')->getCurrentCategory();
$categories = $category->getCollection()
        ->addAttributeToSelect(array('name', 'thumbnail'))
        ->addAttributeToFilter('is_active', 1)
        ->addIdFilter($category->getChildren())
?>
<?php foreach ($categories as $category): ?>
<a href="<?php echo $category->getUrl() ?>"><img src="<?php echo Mage::getBaseUrl('media') . 'catalog' . DS . 'category' . DS . $category->getThumbnail() ?>"/></a>
<?php endforeach; ?>

This his my website where I have it set up, navigate to one of the categories in the Header menu.

Answer 1

Magento caches your current category. You have to options.

Remove static block and call it through xml layout update in the category. Inside the block call

<reference name="needed block"> <action method="setCacheLifetime"></action> </reference>

Or

Get current category via

$this->getRequest()->getParams()

Edit:

In backend go to manage categories Remove static block. Go to layout update and put

<reference name="content">
<block type="core/template" name="my_block" template="subcategories.phtml" before="-">
    <action method="setCacheLifetime"></action>
</block></reference> 

Also you may want to rename the variable $category in .phtml when you are inside the loop. You don't want any time your theme calls $category from that line of code and after to be a child category.

Add below given code into your cms blocks design section

<reference name="content">
         <block type="core/template" name="my_block" template="subcategories.phtml" before="-">
             <action method="setCacheLifetime"></action>
         </block>
</reference>
