The XML process should update every existing product that's included using the SKU / UPC and Title as a key.

There is only one link field supported by default but of course you could add more, or put them in the description.

Sorry Ted, not following, are you saying to re-upload the xml's, if so, will this put the product listings back into the fore of the site content as in the sideblocks for new posts and the activity page, I have just annoyed the hell out of my members by deleting all the listings and uploading the product xml's afresh, long story and rather a dull one. I shouldn't want all the Product listings to appear in the stats as new content again, I would have an uprising on my hands.

Ted, the new version of "productforums.php" works but it does not work totally because doesn't appear the custom fields. :(

If there's no new products there will be no new posts. The system updates what already exists... assuming it can find a match on the SKU or UPC that is.

Gotcha. Try this version...

/upload/productforums.php

Ah right, I didn't include the SKU's, I forgot to add them tot he xml's, and there are no UPC's to be used any way, so running the xml's again without the SKU's will cause problems!

That's a problem indeed...

Do you have reviews on any / many of the products yet?

No there aren't any reviews just yet, I just re-uploaded the xml's recently and no-one has had chance to add reviews yet, but some are due in soon.

Why not make a quick change to your XML to add in SKUs [they don't have to be real to anyone else, just a simple 001, 002, 003, ... works], delete the forum & existing products and reimport now?

This will save you a lot of headache making updates down the road.

Okay, so essentially I need to add sku's no matter what, it makes more sense to me to add the real ones, adding fake sku's would be a bit faster as I would not have to access the real ones from the source site but it feels wrong to me so I will add the real ones.

Ted, once I delete the existing Products and then import the xml's again, is there some way I can stop them from showing in the activity stream. Doing this is really going to annoy my members, it otherwise would add 395 new posts to the activity stream, I can't afford to anger my members with this again. I see I can exclude Product Reviews from the Activity Stream but I can't find any way of excluding the new threads created by the xml's in the forum specified in the core settings..
