Probably the most frequently asked question in the Moodle.org Using Moodle forums is "How do I increase the upload file size limit?" This page will focus upon making changes in on the web server, outside of the Moodle interface.
There are different web server operating systems, thus the method of increasing the uploaded file limit can be different in each.
Overview
File Upload sizes are restricted in a number of different places. The list below shows the order of inheritance that file upload sizes follow.
- PHP Server level - File_upload_size (which is this page)
- Moodle site level - Site_policies
- Course level - Course_settings
- Activity level - Adding/editing_a_forum, Upload_a_single_file_assignment and Advanced_uploading_of_files_assignment
As you can see from the list above, it is the PHP server level that has the greatest precedence. So to increase the file upload size in Moodle we must first adjust this setting. Before we try to adjust any settings in PHP though it is good to know what is set already. We find this out by using a phpinfo script.
PHP Info Script
Create a phpinfo() page or locate the phpinfo section in your Moodle, as per the instructions here: phpinfo
At the very top of the phpinfo page you will see the version of PHP that your server is running. See the relevant section below for information on how to proceed.
PHP Version is 5
If the server is using PHP 5, there may be many php.ini files on the server, but only one will be the active one. Modifying any other copy will do absolutely no good whatsoever. To find the active one, do the phpinfo thing. In the output, near the top of the page, is an item labeled Configuration File (php.ini) Path. This will tell you exactly where the active file is. This is the php.ini that your PHP install is reading.
PHP Version is 4
If you are using PHP 4 you will need a php.ini file in every folder (directory) with php script files.
What web server are you using?
Apache
If you are using an Apache web server you can use .htaccess files to over ride the php.ini settings, or you can edit the active php.ini files on your server.
IIS
.... edit php.ini ?! ...

How is php running on your web server?
The manner in which PHP is running on your web server will determine if you need to restart your web server daemon or not to apply changes you make to the php.ini file.
You can find out how your web server is running PHP by looking at this section of your phpinfo page: Apache2Handler > Loaded Modules Section.
mod_php5 is present
You are running PHP as an Apache Module. You will need to restart Apache to make changes to your php.ini file apply.
??
What access do you have to the server?
To make changes to the main php.ini file you will need administrative access to the server...
Local / Full access to server

Hosted Server
Things can be a little different with a hosted server for uploaded and downloaded file size. You are probably going to to be told to create or change a .htaccess file, or to modify a php.ini file.
- It might be a good idea to talk to with your service provider before you attempt anything. They probably have instructions on "how to" and may have their own limits for uploaded file size. Some hosts measure the file size in gigabytes and others in megabytes. If you are unhappy with their limits, then check your contract and consider changing your provider to one that has a limit and price that you like.
.htaccess with hosted server
The one purpose of an .htaccess file is to override the the current limitations of both the server and the php.ini file. Your hosted server should inform you where that file needs be placed in your Moodle, but generally in the root is sufficient. They may already have a standard file you can use, if so, use it - but perhaps not.
To the .htaccess file add the lines:
php_value upload_max_filesize 128M php_value post_max_size 128M
This will limit uploads to 128MB, but you can make it any size you agree with your provider. The wording may vary slightly, according to the demands of the server.
php.ini with hosted server
Some servers will not allow you to change the moodle root .htaccess file and tell you to use a php.ini file for php directives. Here you can use the instruction located in the section above called Modifying the php.ini file.
Find the php.ini file in your moodle subfolder on your hosted server. You might want to copy the file as a backup just in case. Edit php.ini, find "upload_max_filesize" and post_max_size in the code. After the = change the number. Here the max filesize is 20 megabytes.
upload_max_filesize = 20M post_max_size = 20M
- Tip: Still not changed? Some hosts using cpanel have a php config program under services/software. Use the "Single php.ini" option and make sure you note the location of the php.ini file to modify. This changes the .htaccess file in the same area and thus the server limit for all programs using php.
