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

The 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?

  • 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… and
