織夢站內(nèi)選擇圖片排序是直接read()讀取直接輸出，如果我們同一時間上傳了多個圖片，在沒有經(jīng)過排序的情況下，我們?nèi)ミx擇圖片很難快速分辨哪個是剛剛上傳的，解決方法是讀取該目錄的文件列表,用"文件名、修改時間"做鍵值對,塞入數(shù)組，注意，是用文件名做鍵，因為圖片有可能是同一個時分秒上傳的，并且沒有毫秒，我們無法判斷哪個是快一秒哪個慢一秒。再對"修改時間"倒序，最后foreach輸出即可。

打開 include/dialog/select_images.php 找到

$dh = dir($inpath);
....(中間代碼省略)
$dh->close();

146行到245行，把整個代碼換成下面的代碼
