onunload difference in handling IE and Firefox?

[Peter Reinhardt]

HI,
there must be a difference in handling the window.onunload-Event for the two
webbrowsers.

I have a window, that shows the uptodate-state of the logged in members.
The state (is active / is not active) ist read out of a mysql-database.
I want to update the database when a member leaves, so his state would be
"is not active".
This update is driven through a javascript call for a file.

So now there is a nice situation:
- IE does everything right. It does not kick the member out of the active
list, when updating, but it kicks a member, when the window is closed.

- Firefox kicks a member, when the window is both updated and closed.

Can anyone help me in this subject? I tried to find a solution on the
Internet, but I wasn't successful...

regards,
Peter

Use "onbeforeunload" instead in both cases. regards,

> Use "onbeforeunload" instead in both cases.
here's a part of my php-script:
-------------------------------------------------------------------
echo "<script type='text/javascript'>
<!--
window.onunload = zuper;
function zuper(){
location.href='show.php?closeboard=1&closefile=$fi leId';
//-->
</script>";

if($_GET['closeboard']==1){

$fileId = $_GET['closefile'];
$deleteQ = " DELETE FROM codereview_editors "
." WHERE Nachname = \"$nachname\""
." AND Vorname = \"$vorname\""
." AND FileID = ".$fileId;
$db->query($deleteQ);
}
-------------------------------------------------------------------
Where is my mistake?

Could you give the actual HTML dump instead? If you don't have a PHP
converter handy on your server then simply open the page of question in
any browser and View > Page Source then Copy'n'Past
}

Will be much easier to aswer after the above is done, really.

Would those "two webbrowsers" you are referring to be Konqueror and
ICEBrowser? Do not fall into the mistake of thinking there are only two.
I know of at least 150 and there are more.
I have a window, that shows the uptodate-state of the logged in members.
The state (is active / is not active) ist read out of a mysql-database.

"right" or as you want? There is a difference.
It does not kick the member out of the active list, when updating,
but it kicks a member, when the window is closed.

- Firefox kicks a member, when the window is both updated

What are you calling "updating"? How you update will make a difference.

^^^^^^ here's a part of my php-script:
-------------------------------------------------------------------
echo "<script type='text/javascript'>
<!-- ^^^^ window.onunload = zuper; ^^^^^^^^ function zuper(){
location.href='show.php?closeboard=1&closefile=$fi leId';

$fileId = $_GET['closefile'];

See above. Should be

<script type="text/javascript">
window.onbeforeunload = function()
{
location.href="show.php?closeboard=1&closefile=<?p hp echo $fileId; ?>";
}
</script>
<?php
// if this refers to a checkbox, isset($_GET['closeboard']) is better
if ($_GET['closeboard'] == 1)
{
$fileId = $_GET['closefile'];

// HereDoc syntax is supported since PHP4
$deleteQ = <<<SQL
DELETE FROM codereview_editors
WHERE Nachname="$nachname"
AND Vorname="$vorname"
AND FileID="$fileId"
SQL;

$db->query($deleteQ);
}
?>
