Editing WoW:BagId (section)

{{wowapitype}}
While dealing with container and inventory items, many developers use a bag/slot couple and set bag to -1 for the case of an inventory item. But a problem occurs when the bank is opened (after BANKFRAME_OPENED event being fired) because the 28 slots of the bank count as actual container slots with -1 as bagID. In the same idea, items in the bank bags can be accessed via container item functions (like [[API GetContainerItemLink|GetContainerItemLink(bagID, slotID)]], [[API PickupContainerItem|PickupContainerItem(bagID, slotID)]]) with 5 as bagID for the first bank bag, 6 for the second ... until 11 for the seventh.

To sum up, the current possibilities for bagID are :

* 0 for the backpack
* 1 to 4 for the bags on the character (numbered right to left)
* -2 for the keyring
* -4 for the tokens bag

While the bank is opened:
* -1 for the bank content
* 5 to 11 for bank bags (numbered left to right, was 5-10 prior to 2.0)
