At level 60, can't see the tooltip line "Requires Level X" on ANY items

Mad props to you for being able to create code to fix this, and thanks for sharing it. I’m not feeling daring enough to start copy-pasting code to fix Blizzard’s shortcomings (yet). We shouldn’t have to, anyway.

With the API changes in 10.0.2, the code needed to do this is slightly different now:

local function Add_ReqItem_Level(tooltip, data)
    local _, itemLink = tooltip:GetItem()
    if (itemLink ~= nil) then
        local _, _, _, _, itemMinLevel = GetItemInfo(itemLink) 
        if (itemMinLevel ~= nil and itemMinLevel > 0) then
            tooltip:AddLine("Requires Level "..itemMinLevel)
        end
    end
end

TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Item, Add_ReqItem_Level)

Edit: You can change the innermost if statement so that the item level is only added to the tooltip if it is not already being displayed:

if (itemMinLevel ~= nil and 
    itemMinLevel > 0 and 
    UnitLevel("player") >= itemMinLevel) then

Unfortunately the new patch seems to have messed something up:

It’s still working for me in 10.2.6. Are you having this error on the 10.2.7 PTR?

FWIW, here’s the code I currently have for my version:

local function Add_ReqItem_Level(tooltip)
    if (tooltip ~= ShoppingTooltip1 and tooltip ~= ShoppingTooltip2) then 
        local _, itemLink = tooltip:GetItem()
        if (itemLink ~= nil) then
            local _, _, _, _, itemMinLevel = GetItemInfo(itemLink) 
            if (itemMinLevel ~= nil and 
                itemMinLevel > 0 and 
                UnitLevel("player") >= itemMinLevel) then
                tooltip:AddLine("Requires Level "..itemMinLevel)
            end
        end
    end
end

TooltipDataProcessor.AddTooltipPostCall(Enum.TooltipDataType.Item, Add_ReqItem_Level)
