How to get an exact value in a table ?

[lotus006]

I have some problem with table and I need to get an exact value from my table who have
this inside:

 
tomato    =  red
apple     =  green
onion     =  white

in example I have the Table named "MyTable" and I sort the value with this

[lua]
for i = 1, k do

for k,v in pairs(MyTable) do
print ( v )
end
end [/lua]

Any one have an idea why I have just the value "white" printed 3 times and not all those 3 values ; red,green,white ?

Thanks

[-TB-]

local MyTable = {tomato = "red", apple = "green", onion = "white"}

for k,v in pairs(MyTable)do
     print(v)
end

or you could just use PrintTable(MyTable)

Oh thanks it working :)

I got another question, how can I add the value of my table in a Dmenu ? I have this but i'm not sure how to add it
and all the value need to be on separate line and can be pasted on the DTextEntry.

[lua] local TextEntryBar = vgui.Create("DTextEntry", PanelBottomGrnd)
TextEntryBar:SetText( "" )
TextEntryBar:SetPos( 10, 10 )
TextEntryBar:SetSize( 230, 19 )

-- TextEntryBar:GetValue() .. "\n"

for i = 1, k do

TextEntryBar.OnTextChanged = function ( btn )
local MenuButtonOptions = DermaMenu() -- Creates the menu

MenuButtonOptions:AddOption("hello", function() Msg("Hello") end ) -- Add options to the menu

MenuButtonOptions:Open() -- Open the menu AFTER adding your options
end[/lua]

[lua] local MyTable = {tomato = "red", apple = "green", onion = "white"}

local TextEntryBar = vgui.Create("DTextEntry", PanelBottomGrnd)
TextEntryBar:SetText( "" )
TextEntryBar:SetPos( 10, 10 )
TextEntryBar:SetSize( 230, 19 )

TextEntryBar.OnTextChanged = function ( btn )
local MenuButtonOptions = DermaMenu() -- Creates the menu

MenuButtonOptions:AddOption("hello", function() Msg("Hello") end ) -- Add options to the menu

for k,v in pairs(MyTable) do

MenuButtonOptions:AddOption(k,function() print(v) end)
end

MenuButtonOptions:Open() -- Open the menu AFTER adding your options
end[/lua]

And stop with the for i=1,k do.

[lua]
local MyTable = { }
MyTable[1] = blaah = "Red", yeaa = "Green", pwnage = "White"
MyTable[2] = blaah = "White", yeaa = "Red", pwnage = "Green"
MyTable[3] = blaah = "Red", yeaa = "White", pwnage = "Green"

for k,v in pairs(MyTable)do
print(v.yeaa) -- does print the tables "yeaa" value
print(v.pwnage) -- does print the tables "pwnage" value
print(v.blaah) -- does print the tables "blaah" value
end
[/lua]

thanks for all idea :)

I have an interrogation about this again, if I got

MyTestTable = { "White","Red","Yellow","Green"}

How I can print the only the value "Red" in the console ? or to be more exact , how to print the second value or the third one ?

[lua]print(MyTestTable[2])[/lua]

Prints Red in the console.

How would I remove a specific value from my table, without knowing what its position is? table.remove doesn't do that.

[Flapadar]

[lua]function table.RemoveByValue(tbl , value)
for k , v in pairs(tbl) do
if v == value then
tbl[k] = nil
end
end
return tbl
end

[/lua]

[_Kilburn]

And if you're working with a classic table indexed by number, this won't leave nasty nil holes in your table after the process:

[lua]function table.RemoveByValue(tbl, value)
for i=#tbl,1,-1 do
if tbl[i] == value then
table.remove(tbl, i)
end
end
end[/lua]
