It would probably have to be javascript. Somewhere I've got the JS code that'll allow input based on either a whitelist or deny based on a blacklist. If I can find it, I'll post it here later.

[Nutter]

Here's the JS routine - found it a little quicker than I thought I could :-). It goes in the onkyepress event for the text box.

strList is the whitelist / blacklist

bAllow = true is for whitelist, false is for blacklist

function limitinput(evt, strList, bAllow)
/*Limits the input to strList. If bAllow is true, then
only allow what is in strList. If bAllow is false,
then do not allow what is in strList.*/
{
var charCode = evt.keyCode;
if (charCode==0)
{
charCode = evt.which;
}
var strChar = String.fromCharCode(charCode);
/*controlArray holds the ASCII codes for valid
control commands (BS, CR, LF, etc)*/
var controlArray = Array(0, 8, 9, 10, 13, 27);
var intOut = 0;
if (bAllow==true)
{
if (charCode==8 ¦¦ charCode==9 ¦¦ charCode==37 ¦¦ charCode==39 ¦¦ charCode==46 ¦¦ charCode==116 ¦¦ (strList.indexOf(strChar)!=-1))
/*Valid*/
{
return true;
}
else
{
return false;
}
}
else
{
if (charCode==8 ¦¦ charCode==9 ¦¦ charCode==37 ¦¦ charCode==39 ¦¦ charCode==46 ¦¦ charCode==116 ¦¦ (strList.indexOf(strChar)==-1))
{
return true;
}
else
{
return false;
}
}
}

i dont really understand javascript and how the #*$! would i apply this ty bye :P

[Twisted Mind]

is there something missing in this code :?

[Nutter]

Add this in to your <input> tag...

onKeyPress="javascript:return limitinput(event, '0123456789', true);"

And only 0-9 will be allowed, plus backspace and other control codes.

[LeChuck]

You may want to do this too, in case they have JS disabled:

if (ereg("^[0-9]+$", $input)) {
//do stuff
} else {
// return error page, something like "sorry, only numbers in this field"
}

Part of the problem may be that WW changes all pipe characters to broken pipes. Everywhere there is a pair of broken pipes, there should be two closed pipes - the character when you push shift-backspace.
