Form Data invalid when sending POST(through CURL) to Codeigniter

[eluser]Unknown[/eluser]
Hi there,

hopefully someone can help me.
Let me explain shortly what i want to do:
In an external Website we have a form with Post Data which we want to send through Curl to one Codeigniter Installation.

The Problem is that CI returns a 500 Error together with the message "An Error Was Encountered, The Formulardata u sent is invalid". If i change POSTFIELDS to a simple string it does work, also if i make just a testscript outside CI. So Curl seems to be fine.

Something in CI breaks up the POST array, i also tried to set the permit uri characters.. but that didnt helped ://

Attached the Curl Script and its Output. Code in CI is just a controller with a simple print of $_POST.


Would be great if someone has an idea what could be the problem..

Thanks!!!
