會議室編輯

  1. 原模組會議室設定程式，無法刪除錄影、會議室型態選擇不判斷是否只能錄影、錄影影片列表權限無法區分，必須修改的程式碼相當多。首先，先在開始定義函式新增 moodle 環境變數 $CFG,$DB,$USER。

  2. 修改取得可用錄影影片列表，依據用戶權限取得該用戶所錄置的影片，並將此段程式碼移至會議室型態設定之前，以作為是否有可用錄影影片可用，有才可以選擇播放錄影。有管理 openmeetings 權限的用戶，則列出所有錄影影片。

  3. 判斷目前的會議室是否還沒設定？用戶是否有可用的錄影影片？有錄影影片可用且會議室還未設定，就有四種型態可供設定。如果為已存在的會議室或無錄影可用，則只提供三種會議室型態供設定。其他則只能設定為播放錄影。
