Restrictions key

Set of data validation functions for the key according to the assumed array in the flag.

Introduction

setKeyFlag("Example Key", {type = string type, value = string value, bettwen = table bettwen, function func = function value operation, int len = length only works for string data operations})

The flag function mainly consists of an array and basic concepts such as:

  • string type - A specific data type from Lua and the MTA platform.
  • string value - The type of data type
  • table bettwen - An array with two numeric values ​​from to, the first must be the smallest and the second largest.
  • function func - A function that checks the correctness of data according to your needs, the function structure consists of the default value parameter already added.
  • int len - The value of the maximum accepted data length works for string

Explanation

We divide the type into: userdata, number, string, table, boolean values ​​are not checked by the flag, if they are used, this fragment can be omitted. The accepted types of values ​​for particular things are these:

  • userdata:
    • resource-data
    • xml-node
    • lua-timer
    • vector2
    • vector3
    • vector4
    • matrix
    • account
    • db-query
    • acl
    • acl-group
    • ban
    • text-item
    • text-display
    • vehicle
    • ped
    • player
    • object
    • gui
    • element
  • number
    • int
    • float
  • string
  • table

Bettwen

can use the term bettwen for numeric and string values, The structure of the structure is as follows, example:

setKeyFlag("Example Key", {type = "number",  value = "int", bettwen = {0, 50} })

Values ​​that will be adopted will be between 0 and 50, in the case of others they will not be assigned to the element.

func

A custom function that you can engage if you lack any data validation capabilities for a key.

local funcExample = [[
function(value)
    return value%2 == 0
end]]
setKeyFlag("Example Key", {type = "number",  value = "int", func = funcExample })

-- OR

funcCheckEven = function(value)
    return value%2 == 0
end
setKeyFlag("Example Key", {type = "number",  value = "int", func = funcCheckEven})

This function will check if the number we give is even if it allows it to be assigned to an element.

len value

Length checking for the string data type

setKeyFlag("descrpition", {type = "string", len = 25})

If the value for the description key is 25 characters, then it will be assigned to the element.
