Maximum Upload File Size

:?: Is there an easy way to increase the maximum file upload size (currently 2 megabytes)?

:!: The file upload size is set in your PHP configuration, php.ini, with the parameter upload_max_filesize.

The setting can be changed in a number of different places depending on your webserver and the method it uses to run PHP.

If your Webserver allows the modification of PHP settings through a .htaccess file (Apache + mod_php) add the following two lines to a .htaccess in the installed directory:

php_value upload_max_filesize 15M
php_value post_max_size 15M

Otherwise you need to modify your php.ini (usually located in /etc/php5/php.ini, but refer to your administrator or distribution manual for the correct location):

upload_max_filesize = 15M
post_max_size = 15M

After modifying the global php.ini you will need to restart the webserver to have changes take effect.

Apache Users

Set the following parameter to a reasonable value in your php.ini if you get “Upload Failed” errors after setting upload_max_filesize and post_max_size :

memory_limit = 256M     ; Maximum amount of memory a script may consume (default: 16MB)

Suhosin Users

Users with Suhosin might need to increase the value as well.

Red Hat E5 Servers

Red Hat ES users will also want to check (and probably increase) LimitRequestBody in /etc/httpd/conf.d/php.conf, which is set by default to a fairly low value. This directive specifies the number of bytes from 0 (meaning unlimited) to 2147483647 (2GB) that are allowed in a request body.

FCGI Users

An updated default FastCGI restriction, which limited the maximum body size of a HTTP request results in internal server errors. You may set new values in your apache, i.e.

<IfModule mod_fcgid.c>
  FcgidMaxRequestLen 26214400
  FcgidConnectTimeout 60

for 25 MB and 60 sec timeout.

nginx Users

nginx has its own limit for the maximum request size. You want to increase it by adding the appropriate value in your nginx.conf:

client_max_body_size 25M;

If you want to disable checking by nginx, set it to 0

client_max_body_size 0;
