Tugas 5 PBKK (B)

UPLOAD FILE

Untuk tugas kali ini, saya akan membuat fitur upload file sebagai gambar service yang ditawarkan.

1. Tambahkan method _uploadImage() dan _deleteImage() ke Service_model.php

Method ini akan menghandle upload dan delete gambar.

private function _uploadImage()
  {
    $config['upload_path']          = './upload/service/';
    $config['allowed_types']        = 'gif|jpg|png';
    $config['file_name']            = $this->service_id;
    $config['overwrite']      = true;
    $config['max_size']             = 1024; // 1MB
    // $config['max_width']            = 1024;
    // $config['max_height']           = 768;

    $this->load->library('upload', $config);

    if ($this->upload->do_upload('image')) {
      return $this->upload->data("file_name");
    }

    return "default.jpg";
  }

  private function _deleteImage($id)
  {
    $service = $this->getById($id);
    if ($service->image != "default.jpg") {
      $filename = explode(".", $service->image)[0];
      return array_map('unlink', glob(FCPATH . "upload/service/$filename.*"));
    }
  }

2. Tambahkan pengecekan saat update

Hal ini penting jika service yang diupdate gambarnya tidak diubah atau malah dihapus. Masukkan snippet berikut di "Service_model.php"

public function update()
  {
    $post = $this->input->post();
    $this->service_id = $post["id"];
    $this->name = $post["name"];
    $this->price = $post["price"];


    if (!empty($_FILES["image"]["name"])) {
      $this->image = $this->_uploadImage();
    } else {
      $this->image = $post["old_image"];
    }

    $this->description = $post["description"];
    $this->db->update($this->_table, $this, array('service_id' => $post['id']));
  }

  public function delete($id)
  {
    $this->_deleteImage($id);
    return $this->db->delete($this->_table, array("service_id" => $id));
  }

3. Selesai

Sekarang service sudah bisa ditambahkan gambar, bukan gambar default lagi.

Tambah service tanpa gambar
