if use of this code, show me all data, all names and all ids. what do i do?
i use of codeIgniter
With respect
$search_customer = 1;//$this->input->
Looks like just as the error is telling you. You don't have a column in your database named 'id=1'
Try using an array
$array = array('id'=>$search_customer);
$this->db->get_where('customers', $array);

There's also or_where available:
$this->db->or_where('name', $search_customer);
