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。

文件夹和图片文件处理后效果

实现教程

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 = "
<tr><td class='linerow' colspan='2'><a href='select_images.php?imgstick=$imgstick&v=$v&f=$f&activepath=".urlencode($tmp).$addparm."'><img src=img/dir2.gif border=0 width=16 height=16 align=absmiddle>上级目录</a></td><td colspan='2' class='linerow'> 当前目录:$activepath</td></tr>";echo $line;}else if(is_dir("$inpath/$file")){if(preg_match("#^_(.*)$#i", $file)) continue; #屏蔽FrontPage扩展目录和linux隐蔽目录if(preg_match("#^.(.*)$#i", $file)) continue;$dirarr[] = $file;}
}//End Loop
$dh->close();
arsort($dirarr);
foreach($dirarr as $file)
{$line = "
<tr><td bgcolor='#F9FBF0' class='linerow' colspan='2'><a href='select_images.php?imgstick=$imgstick&v=$v&f=$f&activepath=".urlencode("$activepath/$file").$addparm."'><img src=img/dir.gif border=0 width=16 height=16 align=absmiddle>$file</a></td><td class='linerow'> </td><td bgcolor='#F9FBF0' class='linerow'> </td></tr>";echo "$line";
}
array_multisort($filetimearr,SORT_DESC,SORT_STRING, $filearr);
array_multisort($filetimearr,SORT_DESC,SORT_STRING, $filetimearr);
$result = array_combine($filearr,$filetimearr);
foreach($result as $file => $filetime)
{$filesize = filesize("$inpath/$file");$filesize = $filesize / 1024;if($filesize != "")if($filesize < 0.1){@list($ty1, $ty2) = split(".", $filesize);$filesize = $ty1.".".substr($ty2, 0, 2);}else{@list($ty1, $ty2) = split(".", $filesize);$filesize = $ty1.".".substr($ty2, 0, 1);}if(preg_match("#.(gif|png)#i", $file)){$reurl = "$activeurl/$file";$reurl = preg_replace("#^..#", "", $reurl);if($cfg_remote_site=='Y' && $remoteuploads == 1){$reurl  = $remoteupUrl.$reurl;}else{$reurl = $reurl;}if($file==$comeback) $lstyle = " style='color:red' ";else  $lstyle = "";$line = "

}

后台模板管理按名称排序修改

打开 dede/templets/templets_default.htm 找到

$dh = dir($templetdird);

改成

$files = scandir($templetdird);

继续找到

while($filename=$dh->read())

改成

foreach($files as $filename)

完成
