#17958 [Com]: <input type=file> loses $_POST vars

ID: 17958 Comment by: adeshner@pisem.net Reported By: ddp@deakin.edu.au Status: Critical Bug Type: Apache2 related Operating System: Linux 2.4.18 PHP Version: 4.2.3 New Comment: I am using PHP 4.2.3 with Apache/1.3.20, RedHat 7.2. When uploading files with enctype="multipart/form-data" I experienced the next problem: all files of types other then text/plain or text/html had been corrupted, e.g., the first 4 lines of a gif picture were: GIF89a
% wered.gif" Content-Type: image/gif GIF89a
% , that is, the file name was "ra-powered.gif", a part of this, content-type and an empty line from the posted data had been added to the beginning of the file. The following image data remained intact. The preceding post variable (as phpinfo() listed: _POST["submit-type"] updat - must be "update" _FILES["picture"] Array ( [name] => ra-powered.gif [type] => image/gif [tmp_name] => /tmp/phpjsjZRj [error] => 0 [size] => 3810 ) _SERVER["CONTENT_TYPE"] multipart/form-data; boundary=---------------------------7d213414b022e ) had been corrupt (1-4 last characters cut off, depends on the content-type). All other variables were ok. The problem is only with IE 6.0, Opera, Netscape6 and Konqueror are ok. Tests with PHP 4.2.0 and 4.2.2 show the same results.

The http requests are multipart/form-data. A sample request: POST /cgi-bin/XXXXXXX HTTP/1.1 Authorization: Basic XXXXXXXX Content-Type: multipart/form-data; boundary=XXXssxvnjhpdqdxvcrastvybcwvmgnykrXXX User-Agent: Java1.4.0 Host: XXX.XXX.XXX.X:XXX Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 Connection: keep-alive Content-length: 142 XXXssxvnjhpdqdxvcrastvybcwvmgnykrXXX Content-Disposition: form-data; name="fieldName" fieldValue XXXssxvnjhpdqdxvcrastvybcwvmgnykrXXX-- The $_POST array is empty. I have tested against IBM HTTP Server/V5R2M0 and have not had a probelm retrieving multipart/form-data POST variables using IBM REXX CGI Parse. I am pretty sure my header is valid. Thanks, Jeff ------------------------------------------------------------------------ [2002-09-16 09:19:23] marc@twisted-pair.de I currently have got the problem of lost _POST-Vars even without the enctype=... stuff. All post vars are lost. Browsers: Mozilla/1.0, lynx OS: Debian Linux/PPC Server: Apache 2.0.40 PHP: 4.2.3/4.3.0(cvs) Is there any "workaround"? (e.g. downgrading Apache or PHP) ------------------------------------------------------------------------ [2002-09-12 07:24:01] kalowsky@php.net updating version ------------------------------------------------------------------------ [2002-09-12 05:42:28] ichwilleineemailadresse@gmx.net The Bug still appears in PHP 4.2.3 ------------------------------------------------------------------------ [2002-08-26 10:12:39] arash@yalpani.de I have a similar problem using PHP 4.2.2 and Apache 1.3.23. But only the first value of the $_POST-vars gets lost. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
