note 23364 added to function.header

well, i spend 3 full days now trying to understand why IE 5.5 and IE6 cant handle the following code when using the POST method: ==================================================== <? if(@$_POST["submit"]){ $file_name="mypdf.pdf"; header("Content-type:application/pdf"); header("Content-Disposition: inline; filename=\"mypdf.pdf\""); header("Content-length:".(string)(filesize($file_name))); header("location: $file_name"); exit(); } ?> <form method=post> <INPUT TYPE="submit" name=submit value=bbb> </form> ==================================================== and i still haven't figured out why. it is suppost to output a pdf file to the browser. however, i discovered that IE handles it correctly when using the GET method instead of the POST method (netscape handles it correctly either way) so, all i can suggest to people who wan't to display pdf files in IE and use a form in their page, use the GET method instead of the POST method! with GET it works just fine, with POST it won't work i also tried this: but with negative results also: ==================================================== <? error_reporting(E_ALL); if(isset($_POST["download"])){ $file_name=$_POST["download"]; $fp = @fopen($file_name,"rb"); if ($fp!=NULL) { header("Content-type:application/octetstream"); header("Content-Disposition: inline;filename=\"mypdf.pdf\""); header("Content-length:".(string)(filesize($file_name))); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: no-cache'); header('Expires: 0'); fpassthru($fp); fclose($fp); } exit(); } ?> <form method=post> <INPUT TYPE="submit" name=download value="mypdf.pdf"> </form> ==================================================== tested with php4.2.1 on win2000/IIS5, win2000/apache and linux/apache -- http://www.php.net/manual/en/function.header.php http://master.php.net/manage/user-notes.php?action=edit+23364 http://master.php.net/manage/user-notes.php?action=delete+23364 http://master.php.net/manage/user-notes.php?action=reject+23364
