です。 $は有効な変数ではありません

function edit($) 
{ 
    // check if the appointment exists before trying to edit it 
    $appointment = $this->Appointment_model->get_appointment($); 

（$）を変数に変更してください。たとえば（$ id）を更新して、get_appointment($id)を更新してください。

function edit($id) 
{ 
    // check if the appointment exists before trying to edit it 
    $appointment = $this->Appointment_model->get_appointment($id);
