I'm using jQuery.post, one of the fields is a large string. it's probably 2MB of text.

The jQuery.post request goes through okay, but this field doesn't exist in PHP's $_POST array. All other posted fields are fine. It's definitely being sent, and is actually in file_get_contents("php://input")

If I reduce the size of the large string, it appears in the $_POST data again.

How can I remove this field size limit so PHP will push the large field into $_POST?

EDIT: I changed post_max_size to 100M and it didn't change anything.

  • That is ~1048576 characters! (2 byte chars). This sounds like a server setting issue. Is your post value on the end?
  • The default post_max_size is 8MB, so it might not be related to PHP's configuration...
  • I think you're right with that suhosin thing. I have suhosin.post.max_value_length 1000000 which is less than 1MB. I'm having trouble changing it via htaccess though.
  • From what i remember with my "experience" with suhosin this vars cant be overwritten from .htaccess`. Maybe this will help stackoverflow.com/questions/12718609/…
  • Lol, that's a hack and very bad for performance. I can't believe that answer is accepted... I found out there's a suhosin.ini, I changed that and it's all good.
  • I did not say that it`s a perfect solution and you did not say that you have access to configuration files.
  • It seems Suhosin was enforcing a limit on the number of form elements (or POST variables) that could be submitted in a single form. See mou.me.uk/2012/08/20/… and diywpblog.com/how-to-increase-max-input-vars
