WP post max size being used for Upload file size

[Paulds11]

i guys just to let you know
Centos LAMP server >PHP config editor. I couldnt upload a plug-in but my PHP server settings had upload_max_filesize=90M for a 55m file should be ok right?
well, turns out post_max_size = WordPress “Maximum upload file size” which seems odd to me, i think the directive is incorrect.

So it seems WordPress is using post max size directive as its measure of Üpload file size instead of upload_max_filesize ?

Hi @Paulds11, welcome to Trac! Thanks for the ticket.

Both post_max_size and upload_max_filesize values affect uploads, as well as memory_limit. To upload large files, post_max_size must be larger than upload_max_filesize, and memory_limit should be larger than post_max_size. This is how PHP uploads work in general, not just in WordPress.

ok I didn't know that. Seems odd to me.
