Programatically get subcategories of several root categories with collection

Question

I am working on a collection query of categories:

$categories_check = Mage::getModel('catalog/category')
    ->getCollection()               
    ->setStoreId($storeId)           
    ->addFieldToFilter('is_active', 1)       
    ->addAttributeToFilter('path', array('like' => "1/{$rootCategoryId}/%"))   
    ->setProductStoreId($storeId)   
    ->setLoadProductCount(1)   
    ->addAttributeToSelect('*');

It returns the categories below root category $rootCategoryId. My requirement is to change this query, that it works for an array of root categories.

Like when I pass the array $rootcat = array('15,20,25,35'); it provides me categories below these root categories.

Edited:

As basic of on your last question Programatically get category collection by multiple root category id .I have give you the answer.

Have create multiple OR condition for addFieldToFilter() for getting the result on basic of path field

You should this script which may be give u your required result.

require_once "YOurMagentoDirapp/Mage.php";
umask(0);
ini_set('display_errors', 1);
Mage::app("admin");


$buildArray=array();

$rootId = Mage_Catalog_Model_Category::TREE_ROOT_ID;
$rootids= array(12,15,18,20);

foreach($rootid as $id){

  $buildArray[]= array('attribute' =>'path','like'=>$rootId.'/'.$id.'/%');

}

$collection = Mage::getModel('catalog/category')->getCollection()
        ->addFieldToFilter('is_active',1)
->addFieldToFilter($buildArray);

For getting the query of a collection.You can try this.

$CollectionObject->getSelect()->__toString();

For you case. use below

echo $categories_check->getSelect()->__toString();

Donot use

• ->setStoreId($storeId)

• ->setProductStoreId($storeId)

• ->setLoadProductCount(1)

You can pass an array of conditions to addAttributeToFilter, then it will be combined with OR.

The syntax is as follows:

->addAttributeToFilter(array(
    array('attribute' => 'path', 'like' => "1/15/%"),
    array('attribute' => 'path', 'like' => "1/20/%"),
    array('attribute' => 'path', 'like' => "1/25/%"),
    array('attribute' => 'path', 'like' => "1/35/%"),
))

Create this array parameter with a loop over your input array and you are set.
