Percent character replaced in Codeigniter

Question

In Codeigniter I\'m sending a string using POST method as \"%100\" and it becomes \"0\". I believe this is because they\'re being treated as encode

Answer 1

Just look for the remove_invisible_characters() function defined in the CodeIgniter system/core/Common.php which is called by the function CI_Input::_sanitize_globals(). It is responsible for the cleanup of certain escape sequences starting with "%". I prefer to override the input class to disable the automatic sanitization of the globals.
