上次成功加入GET跟POST，這次我們要建立一個通用的Models。

有時我們會遇到重複使用新增、修改、刪除的變數，這時我們需要一個通用的功能來達成目的，首先我們先在Models新增Mod_universal.php檔案：

<?php defined('BASEPATH') or exit('No direct script access allowed');

class Mod_universal extends CI_Model {
  public function __construct() {
      parent::__construct();
  }
}

/* End of file Mod_universal.php */

接著我們透過指令新增功能，參考文件可以尋找libraries/Mongo_db.php。

確認資料是否存在

  /**
   * 確認資料是否存在
   * verify = 驗證
   * likes = 相似關鍵字
   * table = 資料庫名稱 (必要)
   */
  function chk_once($dataQuery){
    if (isset($dataQuery['verify'])) $this->mongo_db->where($dataQuery['verify']);
    if (isset($dataQuery['likes'])) {
      foreach ($dataQuery['likes'] as $key => $value) {
          $this->mongo_db->like($key, $value);
      }
    }
    $response = $this->mongo_db->count($dataQuery['table']);
    if ($response == 0) {
      return false;
    } else {
      return true;
    }
  }

取得資料數量

  /**
   * 取得資料數量
   * verify = 驗證
   * likes = 相似關鍵字
   * table = 資料庫名稱 (必要)
   * record = 特殊資料
   */
  function get_count($dataQuery){
    if (isset($dataQuery['verify'])) $this->mongo_db->where($dataQuery['verify']);
    if (isset($dataQuery['likes'])) {
      foreach ($dataQuery['likes'] as $key => $value) {
        $this->mongo_db->like($key, $value);
      }
    }
    if (isset($dataQuery['record']['between'])) {
      $this->mongo_db->where_between($dataQuery['record']['between']['item'], 
      $dataQuery['record']['between']['start'], $dataQuery['record']['between']['end']);
    }
    if (isset($dataQuery['record']['where_in'])) {

基本上透過傳入值來新增內容，其中裡面的table代表特定資料庫是必要的。
今天我們就到這，明天接下去寫新增、刪除、修改。
