cannot get data by id in codeigniter

Question

I want to get detailed data about a user by their id but when I try, I get an error: undefined variable .

controller

function index()
    {       

        $this->data['prodi'] = $this->mprodi->get_prodi();

        $id_anggota = $this->uri->segment(3);


        $this->load->model('mdaftar');
        $this->data['anggota'] = $this->mdaftar->get_daftar();
        $this->data['detail'] = $this->mdaftar->get_daftar_detail($id_anggota);

        dump($this->mdaftar->get_daftar_detail($id_anggota));
        echo '<pre>'. $this->db->last_query() . '</pre>' ;


        $this->data['title'] ='UKM Taekwondo';
        $this->data['orang'] = $this->mlogin->dataPengguna($this->session->userdata('username'));
        $this->data['contents'] = $this->load->view('anggota/profil', $this->data, true);
        $this->load->view('template/wrapper/anggota/wrapper_ukt',$this->data);

    }

model

function get_daftar_detail($id_anggota)
    {

        $this->db->select('*');
        $this->db->from('mahasiswa');
        $this->db->join('pendaftaran_anggota','pendaftaran_anggota.nim = mahasiswa.nim','left');
        $this->db->where('id_anggota',$id_anggota);
        $this->db->join('prodi','prodi.id_prodi = mahasiswa.id_prodi','left');
        $data = $this->db->get();
        return $data->row();
    }

and this is the view

 <a href="<?php echo site_url('anggota/profil/'.$id_anggota); ?>">

        <div class="ui instagram button widget-body">
            Kelola Profil
        </div>
 </a>

error is undefined variable id_anggota in the view. Please help me with what to do.

Answer 1

Ofcourse you will get error because you didn't passed that id in controller ,

$this->data['yourid'] = $this->uri->segment(3);

And use this id to your view.

Answer 2

在您的控制器中尝试这样的事情

$data['id_anggota'] = $this->uri->segment(3);
