织梦DedeCMS后台文件列表按文件名排序的方法简介
<p>织梦DedeCMS系统的后台文件, 默认的排序很乱, 不是按名称, 也不是按时间, 如果目录内容很多的话, 很难找到自己想要的文件，实在是太不方便了, 就像下图的排列方式那样，找不到规律。</p>
<p>
于是想让这些文件列表按名字排序, 看了一下后台的文件, 原来是因为php的函数dir引起的, 以“默认模板管理”在文件列表为例, 在后台的找到模板文件: /dede/templets/templets_default.htm (dede为你的后台目录), 打开这个文件找到:</p>
<blockquote>
<ol class="dp-c">
<li class="alt">
<span><span><?php </span></span>
</li>
<li>
<span><span class="vars">$dh</span><span> = dir(</span><span class="vars">$templetdird</span><span>); </span></span>
</li>
<li class="alt">
<span><span class="keyword">while</span><span>(</span><span class="vars">$filename</span><span>=</span><span class="vars">$dh</span><span>->read()) </span></span>
</li>
<li>
<span>{ </span>
</li>
<li class="alt">
<span><span class="keyword">if</span><span>(!preg_match(</span><span class="string">"#\.htm#"</span><span>, </span><span class="vars">$filename</span><span>)) </span><span class="keyword">continue</span><span>; </span></span>
</li>
<li>
<span><span class="vars">$filetime</span><span> = </span><span class="func">filemtime</span><span>(</span><span class="vars">$templetdird</span><span>.</span><span class="string">'/'</span><span>.</span><span class="vars">$filename</span><span>); </span></span>
</li>
<li class="alt">
<span><span class="vars">$filetime</span><span> = MyDate(</span><span class="string">"Y-m-d H:i"</span><span>,</span><span class="vars">$filetime</span><span>); </span></span>
</li>
<li>
<span><span class="vars">$fileinfo</span><span> = (isset(</span><span class="vars">$fileinfos</span><span>[</span><span class="vars">$filename</span><span>]) ? </span><span class="vars">$fileinfos</span><span>[</span><span class="vars">$filename</span><span>] : </span><span class="string">'未知模板'</span><span>); </span></span>
</li>
<li class="alt">
<span>?> </span>
</li>
</ol>
</blockquote>

文件已经全部按名字排序了,很容易找到自己要的文件:可以看得出来使用了PHP的dir函数导致的, dir()读取的文件是无序的, 现在我们要想办法让他按名字排序, 这里可以改另一个读取目录文件的函数scandir(); 这个函数的文件会按文件名称排序, 改成下面这样:</p>
<blockquote>
<ol class="dp-c">
<li class="alt">
<span><span><?php </span></span>
</li>
<li>
<span><span class="vars">$files</span><span> = scandir(</span><span class="vars">$templetdird</span><span>); </span></span>
</li>
<li class="alt">
<span><span class="keyword">foreach</span><span> (</span><span class="vars">$files</span><span> </span><span class="keyword">as</span><span> </span><span class="vars">$filename</span><span>) </span></span>
</li>
<li>
<span>{ </span>
</li>
<li class="alt">
<span><span class="keyword">if</span><span>(!preg_match(</span><span class="string">"#\.htm#"</span><span>, </span><span class="vars">$filename</span><span>)) </span><span class="keyword">continue</span><span>; </span></span>
</li>
<li>
<span><span class="vars">$filetime</span><span> = </span><span class="func">filemtime</span><span>(</span><span class="vars">$templetdird</span><span>.</span><span class="string">'/'</span><span>.</span><span class="vars">$filename</span><span>); </span></span>
</li>
<li class="alt">
<span><span class="vars">$filetime</span><span> = MyDate(</span><span class="string">"Y-m-d H:i"</span><span>,</span><span class="vars">$filetime</span><span>); </span></span>
</li>
<li>
<span><span class="vars">$fileinfo</span><span> = (isset(</span><span class="vars">$fileinfos</span><span>[</span><span class="vars">$filename</span><span>]) ? </span><span class="vars">$fileinfos</span><span>[</span><span class="vars">$filename</span><span>] : </span><span class="string">'未知模板'</span><span>); </span></span>
</li>
<li class="alt">
<span>?> </span>
</li>
</ol>

后台还有其它的有文件列表的地方也一样修改就可以了。</p>
