How to set TAG tags and paging pseudo-static in DedeCMS system

How to set TAG tags and paging pseudo-static in DedeCMS system?

Many CMS systems now have TAGS tags. The well-known DEDECMS also has this function, but its label function is very poor, which is not conducive to SEO optimization. At the same time, there are many problems, such as: when the current page does not exist on the previous page, the link is "-1", and there is also the problem of " This label does not exist in the system and may have been removed."

Today I will teach you how to make labels pseudo-static (some information comes from the Internet), and also fixed some of the above mentioned BUG.

1. Modify the front-end display link

The effect we achieve here is to change the original /tags.php?keywords to /tags/keywords.html.

Here we mainly modify the called tag. In /include/taglib/tag.lib.php, find

$row['link'] = $cfg_cmsurl."/tags?".urlencode($row['keyword']);　　

on line 87 and change it to:

$row['link'] = $cfg_cmsurl."/tags/".urlencode($row['keyword']).".html";

2. Modify the paging code part

We need to modify include/arc.taglist.class.php, find the paging function, and replace it with:

/** 
* 获取动态的分页列表 
* 
* @access public 
* @param int $list_len 列表宽度 
* @param string $listitem 列表样式 
* @return string 
*/
function GetPageListDM($list_len,$listitem="info,index,end,pre,next,pageno") 
{ 
$prepage=""; 
$nextpage=""; 
$prepagenum = $this->PageNo - 1; 
$nextpagenum = $this->PageNo + 1; 
if($list_len == "" || preg_match("/[^0-9]/", $list_len)) 
{ 
$list_len = 3; 
} 
$totalpage = $this->TotalPage; 
if($totalpage <= 1 && $this->TotalResult > 0) 
{ 
return "<span class=\"pageinfo\">共1页/".$this->TotalResult."条</span>"; 
} 
if($this->TotalResult == 0) 
{ 
return "<span class=\"pageinfo\">共0页/".$this->TotalResult."条</span>"; 
} 
$maininfo = "<span class=\"pageinfo\">共{$totalpage}页/".$this->TotalResult."条</span>\r\n"; 
$purl = $this->GetCurUrl(); 
$basename = basename($purl); 
$tmpname = explode(&#39;.&#39;, $basename); 
 
$purl = str_replace($basename, &#39;&#39;, $purl).urlencode($this->Tag); 
//var_dump($purl);exit; 
//$purl .= "?/".urlencode($this->Tag); 
 
//获得上一页和下一页的链接 
//if($this->PageNo != 1) 这是修正上一页为负数的问题
        if($this->PageNo != 1 && $this->PageNo != "")
{ 
$prepage.="<li><a href=&#39;".$purl."-$prepagenum&#39;.html>上一页</a></li>\r\n"; 
$indexpage="<li><a href=&#39;".$purl."-1.html&#39;>首页</a></li>\r\n"; 
} 
else
{ 
$indexpage="<li><a>首页</a></li>\r\n"; 
} 
if($this->PageNo!=$totalpage && $totalpage>1) 
{ 
$nextpage.="<li><a href=&#39;".$purl."-$nextpagenum.html&#39;>下一页</a></li>\r\n"; 
$endpage="<li><a href=&#39;".$purl."-$totalpage.html&#39;>末页</a></li>\r\n"; 
} 
else
{ 
$endpage="<li><a>末页</a></li>\r\n"; 
} 
 
//获得数字链接 
$listdd=""; 
$total_list = $list_len * 2 + 1; 
if($this->PageNo >= $total_list) 
{ 
$j = $this->PageNo - $list_len; 
$total_list = $this->PageNo + $list_len; 
if($total_list > $totalpage) 
{ 
$total_list = $totalpage; 
} 
} 
else
{ 
$j=1; 
if($total_list > $totalpage) 
{ 
$total_list = $totalpage; 
} 
} 
for($j; $j<=$total_list; $j++) 
{ 
if($j == $this->PageNo) 
{ 
$listdd.= "<li class=\"thisclass\"><a>$j</a></li>\r\n"; 
} 
else
{ 
$listdd.="<li><a href=&#39;".$purl."-$j.html&#39;>".$j."</a></li>\r\n"; 
} 
} 
$plist = &#39;&#39;; 
if(preg_match(&#39;/info/i&#39;, $listitem)) 
{ 
$plist .= $maininfo.&#39; &#39;; 
} 
if(preg_match(&#39;/index/i&#39;, $listitem)) 
{ 
$plist .= $indexpage.&#39; &#39;; 
} 
if(preg_match(&#39;/pre/i&#39;, $listitem)) 
{ 
$plist .= $prepage.&#39; &#39;; 
} 
if(preg_match(&#39;/pageno/i&#39;, $listitem)) 
{ 
$plist .= $listdd.&#39; &#39;; 
} 
if(preg_match(&#39;/next/i&#39;, $listitem)) 
{ 
$plist .= $nextpage.&#39; &#39;; 
} 
if(preg_match(&#39;/end/i&#39;, $listitem)) 
{ 
$plist .= $endpage.&#39; &#39;; 
} 
return $plist; 
}

3. Set pseudo-static rules

We take iis7 as an example and set the following rules:

<?xml version="1.0" encoding="UTF-8"?> 
<configuration> 
<system.webServer> 
<rewrite> 
<rules> 
<rule name="weather1" stopProcessing="true"> 
<match url="tags/([^-]+)\.html$" ignoreCase="true" /> 
<conditions logicalGrouping="MatchAll"> 
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> 
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> 
</conditions> 
<action type="Rewrite" url="/tags.php?/{R:1}" appendQueryString="false" /> 
</rule> 
<rule name="weather2" stopProcessing="true"> 
<match url="tags/([^-]+)-([0-9]+)\.html$" ignoreCase="true" /> 
<conditions logicalGrouping="MatchAll"> 
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /> 
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /> 
</conditions> 
<action type="Rewrite" url="/tags.php?/{R:1}/{R:2}" appendQueryString="false" /> 
</rule> 
</rules> 
</rewrite> 
</system.webServer> 
</configuration>
