Strange things a'gwan
 

Everything works fine on my store until the customer clicks on one of the 'quick links' I have added to the head.tpl myself.

When they click one of these links in the custom drop down menu's their cart empties or shows some mad amount (probably from another php session). If they then click on the same or another catergory from the 'official' catergory menu their cart reverts back to the state it was in before clicking the drop down link - and any products added via the drop down link catergory aren't added. Also if a customer is logged in clicking on the dropdown menu's logs them out - but again once they hit the 'official' links again they are logged back in and all is well.

???

All I did was create javascript drop down menu's and aimed the links at the same place the 'offical' catergories menu's point to.
Could this php session interupt be happening because I have used the full http:// paths in the link fields? And if so what would be the correct method of calling these links?

For instance at the moment the 12" Vinyl category link is being called by using : http://www.wyzeshop.com/home.php?cat=1

Would it fix it if the link simply read : /home.php?cat=1

You can check the weirdness out for yourselves by visiting http://www.wyzeshop.com and throwing an item or 2 into your cart using the 'official' menu links then click a drop down menu from the top 'Vinyl quick search' and see what happens.

Any help would be most welcome ;)

Whoa. It could be a www non www issue. Try calling the categories from the drop-down menu without the domain. I.E. home.php?cat=1

Yup I second that.

What I also did was first use the drop down menu to select a mp3 download
and then tried the normal left hand menus, which then would not show any items at all even though it said something like 21 item in that category.

Yep I think that fixed it.

All the dropdown links are now : home.php?cat=12 etc

It looks like it was just the http://www. screwing it up.

Thanks for having a look & your help guys :)
