Printing table with ["names"] = true,

[Mortimerlol]

Hello, I have the following table in my savedvariable:

BangCharHateds = {
    ["Demotatz-Quel'Thalas"] = true,
    ["Evies"] = true,
    ["Sengøku-Ysondre"] = true,
    ["Eyman"] = true,
    ["Atheanis"] = true,
    ["Vedepe"] = true,
}

I need print the names in order (A to Z).... Im trying with:

for key, value in pairs(BangCharHateds) do
if BangCharHateds[key] then
print(BangCharHateds[value])
end
end

But prints true,true,true,true.... I need prints the names

Thanks for help!

First, you need to get the keys of your BangCharHateds table into an array, then sort the array and then print it.

local toSort = {}
for k in pairs(BangCharHateds) do
    toSort[#toSort + 1] = k
end
 
table.sort(toSort)
 
-- toSort is now sorted
for i = 1, #toSort do
    print(toSort[i])
end

Thanks u so much!! Im going to test your code.

I trying with it...

-- SORT
local BangCharHatedsOrder = { }
 
for k in pairs(BangCharHateds) do
    tinsert(BangCharHatedsOrder, k)
end
table.sort(BangCharHatedsOrder)
 
for i = 1, #BangCharHatedsOrder do
     local BangCharHatedsOrderedNames = BangCharHatedsOrder[i]
     local categoryData = categories[BangCharHatedsOrderedNames]     
     print(BangCharHatedsOrderedNames)
end

and works...

I have the error called "stack overflow"

local function HSelector(self)
    local toSort = {}
    
    for k in pairs(BangCharHateds) do
        toSort[#toSort + 1] = k
    end
table.sort(toSort)
    for i = 1, #toSort do
        local info = UIDropDownMenu_CreateInfo();
        info.text = toSort[i]
        info.value = toSort[i]
        info.func = function() end;
        UIDropDownMenu_AddButton(info);
    end
end
 
local function UIDropDownMenu_Initialize(btn)
    UIDropDownMenu_Initialize(btn, initialize)
    UIDropDownMenu_SetWidth(btn, 120)
    UIDropDownMenu_SetButtonWidth(btn, 124)
    UIDropDownMenu_SetSelectedID(btn, 1)
    UIDropDownMenu_JustifyText(btn, "LEFT")
 end
 
local dropdown = CreateFrame("Frame", "HSelector", UIParent, "UIDropDownMenuTemplate");
dropdown:SetPoint("CENTER", 0, 0)
dropdown:Show()
UIDropDownMenu_Initialize(dropdown, HSelector);

i never used the function UIDropDownMenu_Initialize (which is an global function of WoW's Api), but you are basically overwriting this global function (not really overwriting globally but for this file) with your own version (local function UIDropDownMenu_Initialize(btn)) in that function you are calling the exact same function again, which creates an infinite loop which leads to a stack overflow

ohhhh yes

local function UIDropDownMenu_Initialize(btn)
  --  UIDropDownMenu_Initialize(btn, initialize)
    UIDropDownMenu_SetWidth(btn, 300)
    UIDropDownMenu_SetButtonWidth(btn, 124)
    UIDropDownMenu_SetSelectedID(btn, 1)
    UIDropDownMenu_JustifyText(btn, "LEFT")
 end

Now the overflow is fixed ^^ but dont generate the list yet.

As i said i am not familiar with that function but what about doing this:

local function HSelector(self)
    local toSort = {}
    
    for k in pairs(BangCharHateds) do
        toSort[#toSort + 1] = k
    end
table.sort(toSort)
    for i = 1, #toSort do
        local info = UIDropDownMenu_CreateInfo();
        info.text = toSort[i]
        info.value = toSort[i]
        info.func = function() end;
        UIDropDownMenu_AddButton(info);
    end
end
 
local function Initialize_UIDropDownMenu(btn)
    UIDropDownMenu_Initialize(btn, HSelector)
    UIDropDownMenu_SetWidth(btn, 120)
    UIDropDownMenu_SetButtonWidth(btn, 124)
    UIDropDownMenu_SetSelectedID(btn, 1)
    UIDropDownMenu_JustifyText(btn, "LEFT")
 end
 
local dropdown = CreateFrame("Frame", "HSelector", UIParent, "UIDropDownMenuTemplate");
dropdown:SetPoint("CENTER", 0, 0)
dropdown:Show()
Initialize_UIDropDownMenu(dropdown);

Create a menu selector with the database names.
