post_get($index[, $xss_clean = NULL])
Parameters:
$index (string) – POST/GET parameter name
$xss_clean (bool) – Whether to apply XSS filtering Returns:
POST/GET value if found, NULL if not Return type:

This method works pretty much the same way as post() and get(), only combined. It will search through both POST and GET streams for data, looking in POST first, and then in GET:
$this->input->post_get('some_data', TRUE);
