im making a form and im using the London Perl Mongers form processing script for processing...however im having trouble. basicaly what i want to do is have the user input some numbers in some fields and just sum those values and print them in another field (or in another page generated when the form is submitted...whichever is easiest)...can anyone help me? how can i go about doing this...i dont have much knowledge in cgi/perl...anyone have an easy way to get around this? thanks
This can be done in virtually any server side scripting out there. You can also do this using javascript which is done in the broswer side itself. Using javascript i would do this:
(its late.. bear with me)
<html>
<head>
<script type="text/javascript">
function validate()
{
var answer
answer = document.myForm.firstNum.value + document.myForm.secondNum.value
document.myForm.answer.value = answer
}
</script>
</head>
<body>
<form name="myForm" action="file.html" onsubmit="return validate()">
Enter the first number:
<input type="text" name="firstNum">
Enter the second number:
<input type="text" name="secondNum">
<br>
Your answer is:
<script type="text/javascript">
document.write(answer)
</script>
<input type="text" name="">
<input type="submit" value="Send input">
</form>
</body>
</html>
Something like that should do it.
