can't send parameter to admin function

You can always use the CodeIgniter URI Class to get the parameters for the different segments.

PHP Code:

$this->uri->segment(n) 


SEE: The CodeIgniter URI Class in the Users Guide.

That is what I always use to get different passed in parameters.

In your case it would be uri segment (3)
