Stop a form from submitting [Resolved]

[ober0330]

I want to check to make sure a field is filled in before the form will submit.

I have this:

function checkforinitials()
{
    if (document.dform.INIT_BADGE.options[document.dform.INIT_BADGE.selectedIndex].value == 'na')
		alert("Please fill in your initials at the top of the form!");
	return false;    
}

Which works when called by this, except that the form still gets submitted when the error message pops up:

<form name='dform' action='submitcal.php' method='post' onsubmit='checkforinitials();'>

However, the submission is done via PHP. How do I stop the page from going through the submission when they haven't filled that item in?

Nevermind. I just had to put "return functionname();" in the onsubmit.
