Here is the code, for some reason, it isn't outputting the text in the echo. What it is doing is displaying the first file upload page, but when it goes to actually upload (this file), nothing is displayed. It is supposed to display a "Now Loading..." graphic.

any help?

[code]<?php
include"db.php";
session_start();
if($_SESSION['logged'] != 1){
header("Location: login.php");
}
ob_start();
echo'

I just noticed:

You're echoing this:
<?include"header.php";?>
</div>
<div class="content">
<div class="clear10">
&nbsp;
</div>
<div style="text-align:center"><img alt="Loading..." src="/images/loading_animated3.gif"></div>
</div>
<div class="footer">
<?include"footer.php";?>

You should echo everything but the includes.


Change your echo html to this:
[code]<?php
echo'
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<link rel="stylesheet" type="text/css" href="style.css">
<title>TzFiles - Free Ultimate File Hosting</title>
</head>
<body>
<div class="container">
<div class="header">';
include"header.php";
echo '</div>
<div class="content">
<div class="clear10">
&nbsp;
</div>
<div style="text-align:center"><img alt="Loading..." src="/images/loading_animated3.gif"></div>
</div>
<div class="footer">';
include"footer.php";
echo'</div>
</div>
</body>
</html>';?>[/code]

scrap that idea, I just found out that it is disabled completely, and I found this out from their wiki:

[QUOTE]PHP functions flush(), ob_flush(), and ob_implicit_flush() will have no apparent effect on DreamHost. For performance reasons on a DreamHost shared host, output is buffered at a higher level than PHP (mod_gzip) and so these commands do not have any visible effect. If you need unbuffered output, you must contact Tech Support to request mod_gzip be disabled for your site.[/QUOTE]
