I have a single category, that has 2 subcategories. Within each of these categories, are 5 subcategories.
Is there a way to get a list of all of these 10 sub-sub-categories?
Thanks
EDIT:
Something like this:
Main Category
Sub_Cat_1
Cat_1
Cat_2
Cat_3
Sub_Cat_2
Cat_4
Cat_5
Cat_6
Wanting output like:
Cat_1
Cat_2
Cat_3
Cat_4
Cat_5
Cat_6
Thanks
All answers so far load children categories in a loop which is generally bad practice and causes execution of many SQL queries where a single one would suffice.
Let $parentCategory
be your Main Category , then this collection will load all subcategories, two levels below:
$subcategoryCollection = Mage::getModel('catalog/category')
->getCollection()
->addFieldToFilter('level', $parentCategory->getLevel() + 2)
->addFieldToFilter('path', ['like' => $parentCategory->getData('path') . '/%']);
The path
field contains the category id prefixed with all ancestor ids in the form 1/2/3
. Database wise it is a column in catalog_category_entity
that has an index, so comparison like this has no performance issues.
Figured it out:
$cat = Mage::getModel('catalog/category')->load(24);
$subcats = $cat->getChildren();
foreach(explode(',',$subcats) as $subCatid)
{
$_category = Mage::getModel('catalog/category')->load($subCatid);
if($_category->getIsActive()) {
$sub_cat = Mage::getModel('catalog/category')->load($_category->getId());
$sub_subcats = $sub_cat->getChildren();
foreach(explode(',',$sub_subcats) as $sub_subCatid)
{
$_sub_category = Mage::getModel('catalog/category')->load($sub_subCatid);
if($_sub_category->getIsActive()) {
echo '<li class="sub_cat"><a href="'.$_sub_category->getURL().'" title="View the products for the "'.$_sub_category->getName().'" category">'.$_sub_category->getName().'</a></li>';
}
}
}
}
Thanks for looking!
I have developed a recursive function to get all children of a category
$categoryObject = Mage::getModel('catalog/category')->load(CATID);
$children = MODEL_OBJECT->getChildCategories($categoryObject);
// IN MODLE FILE
public $_catIds = array();
public function getChildCategories($categoryObject){
$categories = $categoryObject->getChildrenCategories();
foreach ($categories as $catgory){
if($catgory->hasChildren()){
$this->getChildCategories($catgory);
}
$this->_catIds[] = $catgory->getId();
}
return $this->_catIds;
}
Hope this will help you.
$this->getCurrentCategory()->getParentCategory()->getData();
尝试这个
What I do is recursively find the id of the ancestor category. Once found it, I can print the current category sub categories. If the current category has no children, than I will just print the father's subcategory. In this way you can have infinite subcategories and still being able to display a sub category list.
$_helper = Mage::helper("catalog/category");
$rootCat = Mage::app()->getStore()->getRootCategoryId();
$current = Mage::registry('current_category');
show_cat($current,$_helper,$rootCat);
function show_cat($child,$_helper,$rootCat){
if ($child){
//look for anchestor
$parentid = $child->getParentId();
$parent = Mage::getModel("catalog/category")->load($parentid);
if($parentid != $rootCat)
{
//find the anchestor
show_cat($parent,$_helper,$rootCat);
}else{
//is root
$_subcategories = $parent->getChildrenCategories();
if(count($_subcategories)>0){
echo '<ul>';
foreach($_subcategories as $_category){
echo '<li>';
echo '<a href="'.$_helper->getCategoryUrl($_category).'">'.$_category->getName().'</a>';
if($child->getId() == $_category->getId()){
$current = Mage::registry('current_category');
if ($current){
//handle current
$_current_subcategories = $current->getChildrenCategories();
if(count($_current_subcategories)>0){
//the current cat has childrens
echo '<ul>';
foreach($_current_subcategories as $_sub_category){
echo '<li>';
echo '<a href="'.$_helper->getCategoryUrl($_sub_category).'">'.$_sub_category->getName().'</a>';
echo '</li>';
}
echo '</ul>';
}else{
//the current cat has no childrens
$current_parent = $current->getParentId();
$current_parent = Mage::getModel("catalog/category")->load($current_parent );
$_current_subcategories = $current_parent ->getChildrenCategories();
echo '<ul>';
foreach($_current_subcategories as $_sub_category){
echo '<li>';
echo '<a href="'.$_helper->getCategoryUrl($_sub_category).'">'.$_sub_category->getName().'</a>';
echo '</li>';
}
echo '</ul>';
}
}
}
echo '</li>';
}
echo '</ul>';
}
}
}
}
