Answer 1

Just by having a quick look, I can see you're not passing anything to the $data in your entry_update1 function;

public function entry_update1($id) {

    $this->db->where('id', $id);
    $this->db->update('user', $data);

}

You're trying to update 'user' with $data, but you haven't set $data.

Answer 2

You have to run update query this way in CodeIgniter.

        public function entry_update1($id,$data) {

            $this->db->set($data);
            $this->db->where('id',$id);
            $update = $this->db->update('user');
            if($update)
            {
                return true;
            }
            else
            {
               return false;
            }

         }

Answer 3

You are only passing $id in

$this->usermodel->entry_update1($get['id']);

and in function u did

public function entry_update1($id) {
    $this->db->where('id', $id);
    $this->db->update('user', $data);
}

so you have to pass $data also in you function call

$this->usermodel->entry_update1($get['id'], $data);

public function entry_update1($id, $data) {
    $this->db->where('id', $id);
    $this->db->update('user', $data);
}
