All,
I have a page that displays results of a database search. The page contains
a select dropdown box from which the user can pick different options
including the ability to download an Excel or CSV file of the displayed
results. Once the user selects an option from the dropdown, a Javascript
onchange method will kick in, submit the form and process the selected
option. If the option is one of the file download choices, then using
Javascript a new, child window will be opened and the location of the child
will be the PHP download script with the file to download. The script in
the child window will force the browser's download dialog box to open up at
which point the user can save, open, or cancel the file download. The issue
that I have is that some browsers (IE6) will automatically close the child
window when the user has made a selection from the download dialog box while
other browsers (Mozilla) will leave the child window remaining open. I need
to either come up with a way to close the child window once the user has
finsished with the download dialog or force the download script to not run
in a child window. I've thought about applying a timer somewhere but this
isn't reliable because of the unknowns of file download time and user
response time to the download dialog. I don't have a preference as to
whether the solution is all PHP based, all Javascript, or a mix of both -- I
just need a solution to close this child window when complete.
Code is below. As usual, thanks in advance.

Javascript code from the parent search results window opening the child
window & calling the PHP download script:
...
<SCRIPT type= "text/javascript" language="JavaScript">
<!--
DownloadWindow = window.open("../functions/download.php/?Filename=<?echo
$Filename?>", "Download", "toolbar=0, location=0, directories=0, status=0,
menubar=0, scrollbars=0, resizable=0, copyhistory=0, width=200,
height=200");
//-->
</SCRIPT>
...
download.php:
if (isset($_GET['Filename']))
{
if ( $_GET['Filename'] != '' )
{
$Filename = $_GET['Filename'];
header("Content-Disposition: inline; filename=" .
basename($Filename));
header("Content-Type: application/octet-stream");
header("Content-Type: application/force-download");
header("Content-Type: application/download");
header("Content-Transfer-Encoding: binary");
header("Content-Length: " . filesize($Filename));
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
readfile("$Filename");
}
}
