$_POST empty on utf-8 characters

Question

I\'m working on a multilingual site with CodeIgniter. There is a form that posts data to controller, but $_POST is empty when I start to use Turkish characters

Answer 1

Make sure the form tag has accept-charset:

Then in the controller use utf8_decode() when fetching the posted values:

$value = utf8_decode($this->input->post('field_name'));
