I have virtuemart 1.1.3 + joomla 1.5.9
Created script for automatic adding of products by quantity of images in folder.
Need to understand how to add artio link in php script. Because to add it manually will be too routine.

In joomla it is easy to do. You simply need to type title-alias.
But in virtuemart there is no such option, so the question is:
How to add link to artio in php script with predefined name.

I am not sure if I understand your question correctly.
However, in Joomla to create SEO links controlled by ARTIO JoomSEF, you need to create each link via JRouter object.
