织梦站内选择文件夹和图片文件排序

织梦站内选择图片排序是直接read()读取直接输出，如果我们同一时间上传了多个图片，在没有经过排序的情况下，我们去选择图片很难快速分辨哪个是刚刚上传的，解决方法是读取该目录的文件列表,用"文件名、修改时间"做键值对,塞入数组，注意，是用文件名做键，因为图片有可能是同一个时分秒上传的，并且没有毫秒，我们无法判断哪个是快一秒哪个慢一秒。再对"修改时间"倒序，最后foreach输出即可。

打开 include/dialog/select_images.php 找到

$dh = dir($inpath);
....(中间代码省略)
$dh->close();

146行到245行，把整个代码换成下面的代码

$dh = dir($inpath);
$ty1="";
$ty2="";
$filearr = array();
while($file = $dh->read()) {
    //-----计算文件大小和创建时间
    if($file!="." && $file!=".." && !is_dir("$inpath/$file")){
        $filetime = filemtime("$inpath/$file");
        $filetime = MyDate("Y-m-d H:i:s", $filetime);
		$filearr[] = $file;
		$filetimearr[] = $filetime;
    }
    if($file == ".") continue;
    else if($file == "..")
    {
        if($activepath == "") continue;
        $tmp = preg_replace("#[/][^/]*$#i", "", $activepath);
        $line = "
