Magento - Check if subcategory exists in current category - magento

Question

I have the following category setup in my magento store:
store root
|
bedroom kitchen bathroom
| | |
furniture furniture furniture
lighting lighting misc
misc
I need to be able to check if the category misc exists as a subcategory in my current category or not, and if so show a particular block.
So if i was in the kitchen category it would not show but in bedroom and bathroom it would.
How can i do this this check?

Answer 1

To get your sub-category misc
$currentCategoryId = 10;
$collection = Mage::getModel('catalog/category')->getCollection()
->addAttributeToFilter('is_active', 1) //only active categories
->addAttributeToFilter('parent_id', $currentCategoryId)
->addAttributeToFilter('name', 'misc');
To check if your collection contains at least 1 record in it:
if ($collection->getSize() > = 1) {
//'misc' sub-category exists
}
else {
//'misc' sub-category does not exists
}

Answer 2

Load you current category using and get its Id
$currentCat = Mage::registry('current_category');
$currentCatId = $currentCat->getId();
Load the 'misc' sub-category using
$_category = Mage::getModel('catalog/category')->loadByAttribute('name', 'misc');
$_categoryParentId = $_category->getParentCategory()->getId();
if( $currentCatId == $_categoryParentId){
//Do your stuffs
}
Though you have two categories with the same name misc, so you would want to laod category by url-key or parse through the multiple category array to test.

Answer 3

Try flollowing,
<?php
$categoryId = 5;
$categories = Mage::getModel('catalog/category')->load($categoryId)->getChildren();
$catAsArray = explode(',', $categories);
//you can have $catAsArray to check if it has subcategories
foreach($catAsArray as $child)
{
$_child = Mage::getModel( 'catalog/category' )->load( $child );
echo $_child->getName() . '<br />';
echo $_child->getUrl() . '<br />';
echo $_child->getDescription() . '<br />';
}
?>
Or the other way,
<?php
$categoryId = 5;
$_category = Mage::getModel('catalog/category')->load($categoryId);
if($_category->hasChildren())
{
}
?>
