Dedecms实现自动统计当前栏目文档总数的方法
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>本文实例讲述了Dedecms实现自动统计当前栏目文档总数的方法。分享给大家供大家参考。具体分析如下：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
统计当前栏目有多少文章数量我们常用的有两种办法,一种直接在模板页面运行php 并执行sql,还有一种是直接在extend.func.php中加一个统计函数,然后在模板页面调用即可.</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
SQL语句中,有统计的函数,我们可以通过在织梦中使用SQL语句统计的方法,在列表页内显示该栏目共有多少篇文章,这样做的好处是,有助于提升用户体验,比如说我一个文章列表下面有10篇文章,就自动统计出10篇,到20篇的时候自动统计成20篇,这样用户对网站的信息就一目了然了.</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
现将这2种方法分述如下:</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
<strong>第一种：runphp='yes'</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
第一种实现方法就是利用织梦自带的runphp参数来实现这个功能,只需要在您需要显示统计数量的地方直接加入以下代码:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode5" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
{dede:field.typeid runphp='yes'} <br>
global $dsql; <br>
$row = $dsql->GetOne("select count(*) as dd from dede_archives where typeid = @me"); <br>
@me = $row['dd']; <br>
{/dede:field.typeid}</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>保存后重新生成Html文件即可看到具体的效果,但请注意：</span>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
1.本代码无法统计副栏目的文档；</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
2.本代码可用在列表和内容页；<br>
3.代码生成后的效果的动态的,如果添加完内容,必须重新生成相关页面；</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
4.无法统计无主表（例如：分类信息）的文档总数；</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
<strong>第二种：function</strong></p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
第二种就是我们通常所说的函数,在织梦（DedeCMS）中,我们可以利用自定义函数来实现各种效果,实现的具体方法为:</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
1.在/include/extend.func.php 文件的?>上一行加入以下代码:<br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode6" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
function GetTypeNum($tid){ <br>
global $dsql; <br>
$row = $dsql->GetOne("select count(*) as dd from dede_archives where typeid = $tid"); <br>
return $row['dd']; <br>
}</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>2.在模板需求统计栏目文档的地方加入以下代码：</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode7" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
{dede:field.typeid function="GetTypeNum(@me)"/}</div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>保存后生成警惕Html即可,在这里实际上就是执行了自定义函数接口中的GetTypeNum函数,其注意事项与runphp='yes'方法一样.</span>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
