string format

[Desaster]

how to enable a sting format like I want just numbers in my edit box if you type any other thing it won't be written

[Castillo]

You can use the event onClientGUIChanged with guiSetText and string.find.

[Desaster]

useful but i need an other thing I am making a edit box where you should put your the ammo you want and I want that the player just type numbers no text

[Desaster]

what's the problem here ?

      local text = guiGetText ( ammotext ) 
      guiGridListSetItemText (ammoGirdcart, row2, 1, wepName1, false, true) 
      guiGridListSetItemText (ammoGirdcart, row2, 2, text, false, true) 
      guiGridListSetItemText (ammoGirdcart, row2, 3, wepCost1, false, true) 
      ) 

ps: this is in a fuction

[Castillo]

This is an small example:

local curText = "" 
local editBox = guiCreateEdit ( 100, 50, 150, 150, "", false ) 
  
addEventHandler ( "onClientGUIChanged", editBox, 
    function ( ) 
        local text = guiGetText ( source ) 
        if ( text == "" ) then 
            curText = "0" 
            guiSetText ( source, "0" ) 
            return 
        end 
  
        if ( not tonumber ( text ) ) then 
            guiSetText ( source, curText ) 
        else 
            curText = text 
        end 
    end, 
    false 
)

Here is the more simple checker that you can do:

local editBox = guiCreateEdit(0.3,0.1,0.4,0.1,"",true) 
addEventHandler("onClientGUIChanged", editBox, function() 
    local text = guiGetText(source) or "" 
    if not tonumber(text) then --if the text isn't a number (statement needed to prevent infinite loop) 
        guiSetText(source, string.gsub(text, "%a", "")) --Remove all letters 
    end 
end) 

It will remove all letters that are written into a memo or an editbox. Here I used an editbox at line 1, be sure to paste this addEventHandler right after the creation of your editbox and replace the variable at line 2 to match your editbox variable.

EDIT: Oh and you only can write rounded numbers, you can't write a number like this: 100.5

[Castillo]

But that won't remove the characters ( $, %, /, etc ).

how to add this function to your function castillo ?

guiGridListSetItemText (ammoGirdcart, row2, 2, text, false, true) 

[.:HyPeX:.]

if you want to remove stuff try string.gsub with custom patterns. i used this to change all caps to non-caps and hex colours.

(in this case, from an account data)

local named = getAccountData(playerAccount, "name") -- Get the string

local namedd = string.gsub(named, "#%x%x%x%x%x%x", "") --Remove Hex Colour

local named1 = string.gsub(namedd, "[A]", "a") -- start replacing characters

local named2 = string.gsub(named1, "", "b")

local named3 = string.gsub(named2, "[C]", "c")

local named4 = string.gsub(named3, "[D]", "d")

local named5 = string.gsub(named4, "[E]", "e")

local named6 = string.gsub(named5, "[F]", "f")

local named7 = string.gsub(named6, "[G]", "g")

local named8 = string.gsub(named7, "[H]", "h")

local named9 = string.gsub(named8, "", "i")

local named10 = string.gsub(named9, "[J]", "j")

local named11 = string.gsub(named10, "[K]", "k")

local named12 = string.gsub(named11, "[L]", "l")

local named13 = string.gsub(named12, "[M]", "m")

local named14 = string.gsub(named13, "[Ñ]", "ñ")

local named15 = string.gsub(named14, "[N]", "n")

local named16 = string.gsub(named15, "[O]", "o")

local named17 = string.gsub(named16, "[P]", "p")

local named18 = string.gsub(named17, "[Q]", "q")

local named19 = string.gsub(named18, "[R]", "r")

local named20 = string.gsub(named19, "", "s")

local named21 = string.gsub(named20, "[T]", "t")

local named22 = string.gsub(named21, "", "u")

local named23 = string.gsub(named22, "[V]", "v")

local named24 = string.gsub(named23, "[W]", "w")

local named25 = string.gsub(named24, "[X]", "x")

local named26 = string.gsub(named25, "[Y]", "y")

local named27 = string.gsub(named26, "[Z]", "z")

this is how it should work:

  
local Whatever-You-Want = string.gsub(string-To-Check, "Thingy-To-Search", "Remove-With")

Hmmm you right, then this:

local editBox = guiCreateEdit(0.3,0.1,0.4,0.1,"",true) 
addEventHandler("onClientGUIChanged", editBox, function() 
    local text = guiGetText(source) or "" 
    if tonumber(text) then return end 
    local newText = "" 
    for k=0, #text do 
        local char = string.sub(text, i, i) 
        if tonumber(char) then --it's a number 
            newText..char 
        end 
    end 
    guiSetText(source, newText) 
end)

It's never going to work like you think it will. I've tried the same many times and by spamming my keyboard it always adds another character which I don't want. I think you should just allow all characters and then strip them off later.

I dont know if this is going to work, but you can try the combination of onClientGUIFocus, onClientGUIBlur and onClientKey with cancelEvent()

how to enable a sting format like I want just numbers in my edit box if you type any other thing it won't be written

yourGUIEdit = guiCreateEdit( ... ) 
  
addEventHandler( "onClientGUIChanged", yourGUIEdit, function() 
  local currText = guiGetText( source ) 
  local newText = string.gsub( currText, '[^0-9]', '' ) 
  if newText ~= currText then 
    guiSetText( source, newText ) 
  end 
end, false )

thnx all that helps me alot

Hello, I am bumping this topic as I found a really nice and efficient way of allowing only numbers in edit fields ( or anything else you want ).

guiSetProperty(editBox, "ValidationString", "^[0-9]*$") 

This is just an example, it uses regex and can be used for any kind of input filtering.

hmmmm seems nice

Thank you.

guiSetProperty(editBox, "ValidationString", "^[0-9]*$") 

hmmm I tested this and I found out that it has a bug you can copy any text and paste it in it and then you have a text written in it (bad) the best one is that one with tonumber

[Spajk]

Hmmm, I will try to find a better way tomorrow
