Increase max upload file size WordPress multisite

Question

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.

Answer 1

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
