insert in 2 demensional array

[Allow2010]

Hi,

i am using a two dimensional array like this:

Dim $formfields[3][2] = [["element1", "data1"],["element2", "data2"],["elemnt0","data0"]]

there can be x elements.

My problem is that i need to have a certain element at the first position (the order of the other elements does not matter, only on certain element hast to be at position 1).

Dim $formfields[3][2] = [["element0", "data0"],["element1", "data1"],["elemnt2","data2"]]

I wanted to check if a certain element exist in formfields and if it exists, i remove it and re insert it at position 1. If it does not exist, i just want to add it at position 1.

I tried several things, but i could not get this done correctly, due to problems with the array dimensions after removing/adding...

Can anyone show me how to do it right?

thanks in adnvance,

Edit:

here is what already works:

Func _AddOrUpdateFieldIn2DArray($array, $fieldname, $data = "")
    $iIndex = _ArraySearch($array, $fieldname, 0, 0, 1, 2, 1, 0)
    If $iIndex <> -1 Then;the field exists
        If $array[$iIndex][1] = $data Then          
                      ;already up to date
        Else
            ;update
                     $array[$iIndex][1] = $data
        EndIf
    Else
            ;add
            ReDim $array[UBound($array) + 1][2]
        $array[UBound($array) - 1][0] = $fieldname
        $array[UBound($array) - 1][1] = $data
    EndIf
    Return $array
EndFunc

and would like to have something like this also:

Func _AddTobeginningOf2DArray($array, $fieldname, $data = "")
;adds $fieldname to the beginning of the array, removes $filedname from other positions if it already exists

    Return $array
EndFunc

You could have a look at function _ArrayInsert from the Array UDF that comes with AutoIt. The function only works for one-dimensional arrays but it shouldn't be too hard to modify the code.

[Allow2010]

Func _ArrayInsert(ByRef $avArray, $iElement, $vValue = "")

    ; Add 1 to the array
    Local $iUBound = UBound($avArray) + 1
    ReDim $avArray[$iUBound]

    ; Move all entries over til the specified element
    For $i = $iUBound - 1 To $iElement + 1 Step -1
        $avArray[$i] = $avArray[$i - 1]
    Next

    ; Add the value in the specified element
    $avArray[$iElement] = $vValue
    Return $iUBound
EndFunc   ;==>_ArrayInsert

i played with this before, but failed....i will try again...

Or search the forum for 2D arrays. Some users have enhanced the Array UDF so it works fine with 2D arrays.
