File pertemuan minggu lalu bisa didownload disini (pertemuan 10)

untuk membuat sebuah combobox / dropdown berdasarkan relasi tabel pada database bisa menggunakan helper di CodeIgniter

Cara :

Buat sebuah file php dalam folder ( application/helper) dengan nama my_helper.php

<?php
function cmb_dinamis($name,$table,$field,$pk,$selected){
    $ci = get_instance();
    $cmb = "<select name='$name' class='form-control selectan'>";
    $cmb .= "<option value=''>PILIH JURUSAN</option>";
    $data = $ci->db->get($table)->result();
    foreach ($data as $d){
        $cmb .="<option value='".$d->$pk."'";
        $cmb .= $selected==$d->$pk?" selected='selected'":'';
        $cmb .=">".  strtoupper($d->$field)."</option>";
    }
    $cmb .="</select>";
    return $cmb; 
}

Kemudian … . . .

tambahkan fungsi baru di dalam file Biodata.php (application/controller)

private function ayok_upload(){
    $this->load->library('upload');
    $nmfile = 'gbr_'.time(); //nama file saya beri nama langsung dan diikuti fungsi time
    $config['upload_path'] = './gambar/'; //path folder
    $config['allowed_types'] = 'JPG|JPEG|PNG|BMP|png'; //type yang dapat diakses bisa anda sesuaikan
    $config['max_size'] = '20000'; //maksimum besar file 20mb
    $config['file_name'] = $nmfile; //nama yang terupload nantinya
    $this->upload->initialize($config);
}

Selanjutnya Edit fungtion create_action menjadi

public function create_action() 
{
    $this->_rules();
    $this->ayok_upload();
    if ($this->form_validation->run() == FALSE) {
        $this->create();
    } else {

   if(!empty($_FILES['foto']['name']))
        { // empty
            if ($this->upload->do_upload('foto'))
            {
            $gbr = $this->upload->data();
            $data = array(
                'nim' => $this->input->post('nim',TRUE),
                'nama' => $this->input->post('nama',TRUE),
                'jk' => $this->input->post('jk',TRUE),
                'tempat_lahir' => $this->input->post('tempat_lahir',TRUE),
                'tgl_lahir' => $this->input->post('tgl_lahir',TRUE),
                'alamat' => $this->input->post('alamat',TRUE),
                'jur' => $this->input->post('jur',TRUE),
                'no_hp' => $this->input->post('no_hp',TRUE),
                'foto' => $gbr['file_name'],
                );
                    $this->Biodata_model->insert($data);
                    $this->session->set_flashdata('message', 'Create Record Success');
                    redirect(site_url('biodata'));
            }else{
            $this->session->set_flashdata('message_form', '<div id="alert" class="alert alert-danger"><i class="glyphicon glyphicon-ok"></i> GAGAL<br/>Silahkan Coba lagi ! ! !<br/>'.$this->upload->display_errors().'</div>');
                $this->create();
            }
        }else{ // empty
            $data = array(
                'nim' => $this->input->post('nim',TRUE),
                'nama' => $this->input->post('nama',TRUE),
                'jk' => $this->input->post('jk',TRUE),
                'tempat_lahir' => $this->input->post('tempat_lahir',TRUE),
                'tgl_lahir' => $this->input->post('tgl_lahir',TRUE),
                'alamat' => $this->input->post('alamat',TRUE),
                'jur' => $this->input->post('jur',TRUE),
                'no_hp' => $this->input->post('no_hp',TRUE),
                'foto' => '',
           );
        $this->Biodata_model->insert($data);
        $this->session->set_flashdata('message', 'Create Record Success');
        redirect(site_url('biodata'));
        }   
        
    }
}

Kemudian function update_action menjadi

public function update_action() 
{
    $this->_rules();
    $this->ayok_upload();        

    if ($this->form_validation->run() == FALSE) {
        $this->update($this->input->post('id', TRUE));
    } else {


   if(!empty($_FILES['foto']['name']))
        { // empty
            if ($this->upload->do_upload('foto'))
            {
            $gbr = $this->upload->data();
            $hapus = $this->Biodata_model->get_by_id($this->input->post('id', TRUE));
                if(file_exists('gambar/'.$hapus->foto))
                    unlink('gambar/'.$hapus->foto);
            $data = array(
                'nim' => $this->input->post('nim',TRUE),
                'nama' => $this->input->post('nama',TRUE),
                'jk' => $this->input->post('jk',TRUE),
                'tempat_lahir' => $this->input->post('tempat_lahir',TRUE),
                'tgl_lahir' => $this->input->post('tgl_lahir',TRUE),
                'alamat' => $this->input->post('alamat',TRUE),
                'jur' => $this->input->post('jur',TRUE),
                'no_hp' => $this->input->post('no_hp',TRUE),
                'foto' => $gbr['file_name'],
                );
                $this->Biodata_model->update($this->input->post('id', TRUE), $data);
                $this->session->set_flashdata('message', 'Update Record Success');
                redirect(site_url('biodata'));
            }else{
            $this->session->set_flashdata('message_form', '<div id="alert" class="alert alert-danger"><i class="glyphicon glyphicon-ok"></i> GAGAL<br/>Silahkan Coba lagi ! ! !<br/>'.$this->upload->display_errors().'</div>');
                $this->update($this->input->post('id', TRUE));
            }
        }else{ // empty
            $data = array(
                'nim' => $this->input->post('nim',TRUE),
                'nama' => $this->input->post('nama',TRUE),
                'jk' => $this->input->post('jk',TRUE),
                'tempat_lahir' => $this->input->post('tempat_lahir',TRUE),
                'tgl_lahir' => $this->input->post('tgl_lahir',TRUE),
                'alamat' => $this->input->post('alamat',TRUE),
                'jur' => $this->input->post('jur',TRUE),
                'no_hp' => $this->input->post('no_hp',TRUE),
           );
                $this->Biodata_model->update($this->input->post('id', TRUE), $data);
                $this->session->set_flashdata('message', 'Update Record Success');
                redirect(site_url('biodata'));
        }            
    
       
    }
}

function delete

public function delete($id) 
{
    $row = $this->Biodata_model->get_by_id($id);

    if ($row) {
        $this->Biodata_model->delete($id);
        $this->session->set_flashdata('message', 'Delete Record Success');
        redirect(site_url('biodata'));
    } else {
        $this->session->set_flashdata('message', 'Record Not Found');
        redirect(site_url('biodata'));
    }
}
