jagguy Posted July 22, 2007 Share Posted July 22, 2007 OK this fails to download a file in IE and I have no idea as to why this does. What happens is that it downloads the same php file instead of the required file like it should and does do in FF. FF works fine. Why does IE fail to download this from this script and i really need this working ASAP. I can't believe that IE does this and yes i am panicking. I started a new thread as my other threads were getting messy and old on this topic. I just found out about this and HELP $file_extension = strtolower(substr(strrchr($file,"."),1)); if ((isset($file))&&(file_exists('files/'.$file))) { switch( $file_extension ) { case "pdf": $ctype="application/pdf"; break; case "exe": $ctype="application/octet-stream"; break; case "zip": $ctype="application/zip"; break; case "doc": $ctype="application/msword"; break; case "xls": $ctype="application/vnd.ms-excel"; break; case "ppt": $ctype="application/vnd.ms-powerpoint"; break; case "gif": $ctype="image/gif"; break; case "png": $ctype="image/png"; break; case "jpg": $ctype="image/jpg"; break; default: $ctype="application/force-download"; } $ary_header = get_headers($file, 1); $filesize = $ary_header['Content-Length']; // fix for IE catching or PHP bug issue header("Pragma: public"); header("Expires: 0"); // set expiration time header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header("Content-Transfer-Encoding: Binary"); // @header("Content-length: ".filesize($file_path)); header("Content-length: ".$filesize); header("Content-Type: $ctype"); //header("Content-Disposition: attachment; filename=".basename($filename).";"); header('Content-Disposition: attachment; filename="' . $file .

jagguy Posted July 22, 2007 Author Share Posted July 22, 2007 what happens is that it will work for a txt file in IE/FF but fails for a doc file in IE. FF works fine. Also if I use a download manager then this picks up the same php file which it shouldn't . $file_extension = strtolower(substr(strrchr($file,"."),1)); if ((isset($file))&&(file_exists('files/'.$file))) { if(ini_get('zlib.output_compression')) ini_set('zlib.output_compression', 'Off'); switch( $file_extension ) { case "pdf": $ctype="application/pdf"; break; case "exe": $ctype="application/octet-stream"; break; case "zip": $ctype="application/zip"; break; case "doc": $ctype="application/msword"; break; case "xls": $ctype="application/vnd.ms-excel"; break; case "ppt": $ctype="application/vnd.ms-powerpoint"; break; case "gif": $ctype="image/gif"; break; case "png": $ctype="image/png"; break; case "jpg": $ctype="image/jpg"; break; default: $ctype="application/force-download"; } $filename = $HTTP_GET_VARS['path']; // fix for IE catching or PHP bug issue 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 // force download dialog header("Content-Type: application/force-download"); //header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header("Content-Type: $ctype"); //header("Content-Disposition: attachment; filename=".basename($filename).";"); header('Content-Disposition: attachment; filename="' . $file .

jagguy Posted July 22, 2007 Author Share Posted July 22, 2007 I don't think you have read my code as i have done this to the nth degree already. look in my code case "doc": $ctype="application/msword"; break; .. and the filename will have a .doc at the end for readfile. ****The problem is that it fails to work in IE using a doc file BUT works in FF. If I download my.doc in FF it works . If I download my.doc in IE it fails to have any data in the filename. My download manager gets a php file as well when there is none to download. This is really screwy? Link to comment https://forums.phpfreaks.com/topic/61215-force-a-download-in-ie-fails-heellp/#findComment-304596 Share on other sites More sharing options...
redarrow Posted July 22, 2007 Share Posted July 22, 2007 throw all the .doc in a zip then let them download it then or use this works for me sorry can not help otherwise. ps. there are meny bugs in ie from one version to another.

jagguy Posted July 22, 2007 Author Share Posted July 22, 2007 The php download file is in a seperate dir than the file to download .Is this the problem?

jagguy Posted July 23, 2007 Author Share Posted July 23, 2007 If I take out this security check the download works. IE and my download manger kept picking up login.php. I don't actually need this check as any wrong file path or sql injection can be dealt with. Why do I need to do this though? if (isset($_SESSION['HTTP_USER_AGENT'])) { if ($_SESSION['HTTP_USER_AGENT'] != md5($_SERVER['HTTP_USER_AGENT'])) { session_destroy(); header( "Location:". $myvar."/login.php" ); exit; } } else { $_SESSION['HTTP_USER_AGENT'] = md5($_SERVER['HTTP_USER_AGENT']); } if (!isset($_SESSION['uid'])) { header( "Location: ". $myvar."/login.php" ); exit; } Link to comment https://forums.phpfreaks.com/topic/61215-force-a-download-in-ie-fails-heellp/#findComment-305246 Share on other sites More sharing options...
