oh yea... i meant ==. sorry 'bout that. but it still is not showing the popup when i leave the fields empty

but it gives me an error when i use this:

if($('#title').val()='' || $('#description').val()='')

I thought that "," meant or? i know in php, it's ||. what is it in jquery?

and what I am trying to do, is check if title is empty OR description is empty.

I just wasn't sure if you had to call on something to process the form or not.

so then with the php, we would say that the user has javascript disabled, and that would be our backup plan to validating everything?

Lastly, what am I doing wrong here?:

$(function() {
	$("#fileUpload").submit(function(e) {
		flag = false;
		if($('#title').val()='',$('#description').val()=''){
			flag = true;
		}
		if (flag) {
			e.preventDefault();
			alert("Validation failed!");
		} else {
			alert("bad");
		}
	});
});

<form enctype="multipart/form-data" name="fileUpload" id="fileUpload" action="processUpload.php" method="post">
 <input type="submit" id="submitUpload" name="submitUpload" value="Upload" />
//...

oh... i see! so I have to intercept it... so how do I submit it if everything is ok then, with the jQuery?

and so if the user has javascript disabled, the form still submits with the php page...
