If you want to remove parent categories from the Magento category URLs unfortunately there is no setting for this in Magento admin.

Here’s an example of what we are trying to achieve. We’re trying to change this:

handbags.com/handbags-all/style/leather-handbags.html

into this:

handbags.com/leather-handbags.html

The solution requires coping a core file and then editing it. To remove subcategories from Magento category URLs go to the following directory:

app/code/core/Mage/Catalog/Model/

Copy the Url.php and put it in the following directory (creating any folders where necessary):

app/code/local/Mage/Catalog/Model/Url.php

Now edit your new file: approx line 716, find this function getCategoryRequestPath($category, $parentPath) {} comment this lines.

Now comment out as follows:

//if (null === $parentPath) { //$parentPath = $this->getResource()->getCategoryParentPath($category); //} //elseif ($parentPath == ‘/’) { $parentPath = ‘ ‘; //(‘Don’t comment it’) //}

Save the file then go to System->Config->Index Management and reindex everything.

This will flatten your Magento category URLs to remove parent categories
