How do I make fields mandatory on a form?

[Molly]

Hi I have a contact us form that emails me when submitted. However I want to make one of the fields mandatory so that if it isn't filled in it won't let you submit the form. However I not sure how to do it. Could anyone point me in the right direction?

Hi Molly,

Here's a quick little validation script. Let us know if you need any help with your own implementation.

<script type="text/javascript" language="Javascript">
function validate( myform ) {
	if ( myform.email.value == "" ) {
		alert("Please enter your email address.");
		return false;
	}
	
	return true;
}
</script>

<form method="POST" action="mypage.php" onsubmit="return validate(this);">
<input type="text" name="email" value=""> <input type="submit">
</form>
