hi all i have done this captcha (text only) in php and wondered if anyone could help me turn it into coldfusion.
It could be of use to a few people
**************php*******************************
function captcha() {
$numbers = array("zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine");
$rand = array_rand($numbers,2);
$result=$rand[0]+$rand[1];
$question = "<b>".$numbers[$rand[0]]."</b> plus <b>".$numbers[$rand[1]]."</b>";
$out .= '<label for="captcha">Please enter the result into the box below:(Answer in numbers only)<br /> '.$question.' equals</label> <input type="text" name="captcha"id="captcha">';
$out .= '<INPUT TYPE=hidden NAME=val1 VALUE='.$numbers[$rand[0]].'>';
$out .= '<INPUT TYPE=hidden NAME=val2 VALUE='.$numbers[$rand[1]].'>';
$out .= '<INPUT TYPE=hidden NAME=result VALUE='.$result.'>';
return $out;
}
**********************end php***********************
Thanks

I don't know the first thing about PHP so I can't actually translate your script for you, but from my glance thru it I would say that you're looking for arrayNew(1) and randRange() in ColdFusion. (I am assuming that you know how to write a function (a.k.a. UDF) in CF.)

<cfscript>
function captcha() {
var numbers = listToArray("zero, one, two, three, four, five, six, seven, eight, nine");
var rand1 = randRange(1, arrayLen(numbers));
var rand2 = randRange(1, arrayLen(numbers));
var result = rand1 + rand2 - 2; // subtract 2 since CF arrays start at 1 as opposed to 0
var question= "<b>" & numbers[rand1] & "</b> plus <b>" & numbers[rand2] & "</b>";
var out = "";
out = "<label for='captcha'>Please enter the result into the box below: (Answer in numbers only)<br />" & question & " equals</label>";
out = out & "<input type='hidden' name='val1' value='" & rand1 & "'>";
out = out & "<input type='hidden' name='val2' value='" & rand2 & "'>";
out = out & "<input type='hidden' name='result' value='" & result & "'>";
return output;
}
</cfscript>
<cfoutput>#captcha()#</cfoutput>
