Increase max upload file size WordPress multisite

I'm trying to increase the max file size for a WordPress multisite install (currently 1MB). I've tried a number of things to no avail. The things I've tried:

Adding these to my hosts php.ini file:

memory_limit = 300M
post_max_size = 32M
upload_max_filesize = 32M

Adding these to the functions.php file in the theme:

@ini_set('upload_max_size' , '32M');
@ini_set('post_max_size', '32M');
@ini_set('max_execution_time', '300');

Adding these to the .htaccess file:

php_value upload_max_filesize 32M
php_value post_max_size 32M

I even tried checking the wp-includes/default-constants.php.

Interestingly, I have another WordPress install (not multisite) on the same server that seems to work perfectly (max upload there is 32MB). Any ideas what to try next?

Thank you.

Figured it out. In all my infinite wisdom, I completely missed the "Max upload file size" setting in Network Admin > Settings > Network Settings. It's right near the bottom of the page.


@Allpnay posted the solution, just paste on functions.php:

add_filter( 'upload_size_limit', 'PBP_increase_upload' );
function PBP_increase_upload( $bytes )
{
  return 1048576; // 1 megabyte
}

In my case want 8mb so change for return 8000000; // 8 megabyte


Phil is correct: Network Admin (My Sites > Network Admin) then go to Settings > Network Settings. It's near the bottom under Upload Settings, called Max upload file size.

However, also note you have to go with a flat 1000kb or 2000kb etc.

I put 1500kb in there and it still limited me to 1 MB but when I increased it to 2000kb it allowed up to 2 MB


Try this, i use this filter for my Multisite and this work great

add_filter( 'upload_size_limit', 'PBP_increase_upload' );
function PBP_increase_upload( $bytes )
{
return 1048576; // 1 megabyte
}

Create a file called .user.ini in your Wordpress root folder and add the following to it:

upload_max_filesize = 64M
post_max_size = 64M
memory_limit = 64M
max_execution_time = 300

This fixed it for me after all else failed.


Try creating a php.ini file with

memory_limit = 32M
upload_max_filesize = 32M
post_max_size = 32M
file_uploads = On

and save it in the wp-admin/ folder :)

If this doesn't work, try adding the following to wp-config.php

define('WP_MEMORY_LIMIT', '64M');
ini_set('post_max_size', '32M');
ini_set('upload_max_filesize', '32M');
