On occasion, you’ll find yourself needing to know the ID number which corresponds to each category. You can manually find this, as it’s show alongside the category name in Catalogue -> Manage Categories, but if you need them all, this isn’t the most efficient way of going about it. What follows in this post is a simple script to export Magento categories to a CSV file for you to download and use as you see fit. We start by hooking into Magento – the file is going to be uploaded to the web root of the installation, but if you want to upload it anywhere, just change the reference to app/Mage.php in the first line.
<?php require_once 'app/Mage.php'; Mage::app(); $allCategories = Mage::getModel ( 'catalog/category' ); $categoryTree = $allCategories->getTreeModel(); $categoryTree->load(); $categoryIds = $categoryTree->getCollection()->getAllIds();
If we’ve got categories to play with, we then create the CSV file (this is in the var/importexport folder by default, but can be changed to wherever you want) :
if ($categoryIds) {
$outputFile = "var/importexport/categories-and-ids.csv";
$write = fopen($outputFile, 'w');
Then we loop through each category ID in the collection, and write its name and ID to the CSV file :
foreach ( $categoryIds as $categoryId ) {
$data = array($allCategories->load($categoryId)->getName(), $categoryId);
fputcsv($write, $data);
}
}
Finally we then close the CSV file :
fclose($write); ?>
And that’s it – upload the file to your Magento installation, hit the file in your browser (you’ll not get any on-screen output) and your exported Magento categories will be ready to download from the var/importexport folder.
