Magento – If the current category ID exists in this array of IDs, then show something

category

I'm new to Magento, and I would like to know how to add a condition like my title above.

If the current category page is 3, or 4, or 5, or 6, then I need to show something.

Provided that _category is equal to $this->getCurrentCategory, all I can think of is this:

<?php if($_category->getId()==array(3,4,5,6): ?>
// Stuff to show if the current cat is 3 or 4 or 5 or 6
<?php else: ?>
//Stuff to show for other categories
<?php endif; ?>

But it doesn't work. I assume that my usage of array is wrong or I missed something. I hope I Magento/PHP expert can enlighten me. 😀

Thanks in advance.

Use in_array()

Below condition shall work for you

<?php if(in_array($_category->getId(), array(3,4,5,6))): ?>
// Stuff to show if the current cat is 3 or 4 or 5 or 6
<?php else: ?>
//Stuff to show for other categories
<?php endif; ?>

How to Check if Subcategory Exists in Current Category

You can get the list of subcategories of a category like this:

$currentCategoryId = 10; 
$collection = Mage::getModel('catalog/category')->getCollection()
    ->addAttributeToFilter('is_active', 1) //only active categories
    ->addAttributeToFilter('parent_id', $currentCategoryId);

If you want to check if only a specific category is present...in your case with the name 'misc' just add an additional filter to the code above:

$currentCategoryId = 10; 
$collection = Mage::getModel('catalog/category')->getCollection()
    ->addAttributeToFilter('is_active', 1) //only active categories
    ->addAttributeToFilter('parent_id', $currentCategoryId)
    ->addAttributeToFilter('name', 'misc') //filter by name
    ->setPage(1,1) //set a limit to the collection
    ->addAttributeToSelect('url_key');

And you don't even need to load the full collection. You just need to check if the collection from above has at least 1 item in it.

if ($collection->getSize() == 1) {
    // 'misc' exists
    $url = $collection->getFirstItem()->getUrl();
}
else {
    // no 'misc' subcategory for you.
}

Magento Categories – How to Get Magento Categories by Array of Category IDs

Based on the comments....
Instead of $_categories->getParentId()>0 try to check

$_categories->getParentId() != 1 && $_categories->getParentId() != Mage::app()->getStore()->getRootCategoryId().

This should exclude the root of all roots (id 1) and the default root category of the store.
