使用CodeIgniter上傳兩張圖片，重新調整大小並保存到數據庫

Question

我試圖上傳兩張圖片，重新調整大小，然後將它們保存在我的數據庫中，但遇到了一些問題。下面我已經發布了我的控制器。當我print_r（）我的$ db_info數組我得到的photo_one和thumb_one的值，但沒有photo_two或thumb_two。當我print_r（）$ _FILES數組時，所有內容都應該是這樣。任何人都可以看到我失蹤的東西，阻止我的控制器處理第二個圖像？謝謝！

我是初學者，俯瞰失誤的犧牲品。我將我的方法命名爲上傳類的上傳圖片的方法。因此，當我打電話給班級時，事情變得混亂起來。獲得的教訓和解決的問題。
