Hello Jan and others,

I've read several of your answers on the topic of removing the manufacturer_id to prevent dublicate urls. This list was the last I stumbled upon:

1. defining the manufacturer_id as non-sef variable that will be appended to SEF URL
2. reconfiguring the VM extension so that the manufacturer name will be part of the URL
3. adjusting VM code to remove the variable from the URLs

However I can't find any further explanation on how to do one of the above...

My situation is that I have:

en/products/backpacks-and-hipbags/backpacks --> index.php?option=com_virtuemart&category_id=13&lang=en&page=shop.browse&Itemid=53

en/products/backpacks-and-hipbags/backpacks-2 --> index.php?option=com_virtuemart&category_id=13&lang=en&manufacturer_id=0&page=shop.browse&Itemid=53

and

en/products/backpacks-and-hipbags/backpacks/pulsar-50 --> index.php?option=com_virtuemart&category_id=13&flypage=flypage.tpl&lang=en&manufacturer_id=1&page=shop.product_details&product_id=239&Itemid=53

en/products/backpacks-and-hipbags/backpacks/pulsar-50-2 --> index.php?option=com_virtuemart&category_id=13&lang=en&manufacturer_id=1&page=shop.product_details&product_id=239&Itemid=53

So apparently the manufacturer_id and the flypage.tpl gives trouble dublicating all my vm products...

Question: Can you please explain to us earthlings (non-wizzkids) how we could solve this issue?

Hello,

Probably the easiest solution will be to set flypage and manufacturer_id as non-SEF. Use Manage Extensions page in JoomSEF to open Virtuemart extension parameters. There on the Extension tab set "Flypage handling" to "Handle as non-SEF variable". Then on the Common tab set "Custom non-SEF variables" to "manufacturer_id".
