Hey,
Personally i got pretty tired of the javascript popup as soon as my harddrive went full.
It is pretty annoying when you have torrentflux open i a browser, and every 60 seconds a warning popup comes up.
Ok, i have to admin that i could change the disable the pop interval or even the remove the popup itself, but i still wanted a reminder that i'm out of Gbs.
Anyway, i created a lame hack that shows a warning on the page itself in bold red letters, instead of an annoying popup.

yup, i also know that i already have a drivespace bar show the amount i have left, but personally i like a big)bold red warning

Anyway, on with the little hack.
Open index.php
Search for:
if($drivespace >= 98)
{
echo "\n\n<script language=\"JavaScript\">\n alert(\""._WARNING.": ".$drivespace."% "._DRIVESPACEUSED."\")\n </script>";
}
and change it to:
/* if($drivespace >= 98)
{
echo "\n\n<script language=\"JavaScript\">\n alert(\""._WARNING.": ".$drivespace."% "._DRIVESPACEUSED."\")\n </script>";
}
*/
by this the popup will be disabled

Now to implement the big bold warning.
Search for the end of the table just before the torrent listing and add this above </table>:
<?php
//Big bold warning hack by FLX
if($drivespace >= 98){
echo '<tr>
<td bgcolor="'.$cfg['table_data_bg'].'" colspan="2" nowrap>
<div align="center">
<font face="Arial" size="2" color="red">
<strong>
Warning! ';
echo $drivespace;
echo '% drivespace is used! You have ';
echo formatFreeSpace($cfg["free_space"]);
echo ' left!
</strong>
</font>
</div>
</td>
</tr> ';
} ?>
If you dont like that location, just put it somewhere else

I hope this helps you, and keep torrentflux going!
Regards,
FLX
