richrock Posted June 18, 2010 Share Posted June 18, 2010 Hi, I've been trying to get a script to force a download of a zip archive, but it's not working... I am too dumb to figure why, although I've tried a lot of options. // Create a zip file based on parameters. // Set up the POST data $z_title = $_POST['album']; $z_id = $_POST['id']; require_once('../../../configuration.php'); $jconfig = new JConfig(); $db_error = "Database not found. Please contact a system administrator."; $db_config = mysql_connect( $jconfig->host, $jconfig->user, $jconfig->password ) or die( $db_error ); mysql_select_db( $jconfig->db, $db_config ) or die( $db_error ); $q = "SELECT zip_file FROM jos_music_albums WHERE id = '" . $z_id . "'"; $query_execute = mysql_query($q); $result = mysql_fetch_row($query_execute); $destination = $result[0]; mysql_close($db_config); $destination_alpha = basename($destination); $destination_bravo = $_SERVER['DOCUMENT_ROOT']. "/bromptons_auctioneers_15/" . $destination; $filesize = filesize($destination); header("Pragma: public"); // required header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: private",false); // required for certain browsers header("Content-Type: application/zip"); header("Content-Disposition: attachment; filename=\"".basename($destination)."\";" ); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".$filesize); readfile("$destination"); exit; The actual test file is a zip archive located in http://www.sitename.com/music/artist/album.zip It's *definitely* there I have tried using absolute paths either from the url or from the fileserver, and relative paths don't seem to work either. The error I get (this was with the code above): Warning: filesize() [function.filesize]: stat failed for music/Sibelius/Sibelius/Sibelius.zip in F:\html\bromptons_auctioneers_15\components\com_music\assets\zipit.php on line 25 Warning: readfile(music/Sibelius/Sibelius/Sibelius.zip) [function.readfile]: failed to open stream: No such file or directory in F:\html\bromptons_auctioneers_15\components\com_music\assets\zipit.php on line 36 When I have managed to get this to work (supposedly), I crash the browser. The memory usage leaps up - first time I noticed my browser was using 1.8gb of memory, increasing by about +/- 250mb a second. This seems to occur everytime I use absolute paths, and cannot figure why. Firebug reports nothing wrong (maybe it's failed by this point), and am at a loss. Any ideas/alternative code would be appreciated - codes a bit of a mess too, there's remants of stuff I've tried before too... Quote Link to comment Share on other sites More sharing options...
kenrbnsn Posted June 18, 2010 Share Posted June 18, 2010 The filesize() & readfile() functions need the original file, not the destination. Also, how are you invoking this code? Ken Quote Link to comment Share on other sites More sharing options...
richrock Posted June 18, 2010 Author Share Posted June 18, 2010 Thanks, I'll check into those. I'm running the script via ajax, sending variables to trigger the on the download script. Quote Link to comment Share on other sites More sharing options...
richrock Posted June 18, 2010 Author Share Posted June 18, 2010 Right it's now working, although I have another problem affecting the downloads - filesize($filename) fails. The error I get is: Warning: filesize() [function.filesize]: stat failed for /bromptons_auctioneers_15/music/Sibelius/Sibelius/01 Violin Concerto.mp3 in F:\html\bromptons_auctioneers_15\components\com_music\assets\zipit.php on line 35 And I have tried using clearstatcache() at the start of the script to reset anything. Still with the errors... FWIW - the typical filesizes are around the 15-20mb mark... Quote Link to comment Share on other sites More sharing options...
richrock Posted June 18, 2010 Author Share Posted June 18, 2010 Right, figured the filesize refers to actual location (as mentioned earlier), so I now get a report of 34064439 when I get the filesize of a 15mb mp3. That may explain why I'm only getting 400-1000k download file sizes. Can anyone help with filesize()? Quote Link to comment Share on other sites More sharing options...
