Anchor problem

[eluser]Adnan1984[/eluser]
Hello to All, Here is my program code:
In Model:

Code:

public function manage_user_model(){
        $query = $this->db->get('agent');
return $query->result();
    }
    
    public function delete_user($userid){
        $query = $this->db->get_where('image' , array('agent_id' => $userid));
        $data['image']=$query->row_array();
      
        $this->db->where('agent_id',$this->uri->segment(3));
$this->db->delete('agent');
        
        if($this->db->affected_rows() >= 1){
            $path1=realpath(APPPATH.'../uploads/thumbs/'.$data['image']['reference_num'].''.$data['image']['ext']);
            $path2=realpath(APPPATH.'../uploads/'.$data['image']['reference_num'].''.$data['image']['ext']);
            if(unlink($path1) AND unlink($path2)){
                return TRUE;
            }else{
                return FALSE;
            }
        }
    }

In Controller:

Code:

public function manage_user($userid){
            $this->load->library('table');
            $this->load->model('admin_model');
            $this->admin_model->delete_user($userid);
            $data = array();
            $query = $this->admin_model->manage_user_model();
            if($query){
                $data['record'] = $query ;
            }
            $data['username'] = $this->session->userdata('username');
            $this->load->view('manage_user_view',$data);
    }

If i opened like "http://localhost/ci_eee/index.php/site/manage_user" and i got error message and it says:

A PHP Error was encountered
Severity: Warning
Message: Missing argument 1 for Site::manage_user()
Filename: controllers/site.php
Line Number: 113

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: userid
Filename: controllers/site.php
Line Number: 120

If i changed like "http://localhost/ci_eee/index.php/site/manage_user/12" then no error.
Can you solve me this problem?
Thanks

Code:

public function manage_user($userid){

You are telling it to expect a value.
