直接进入主题,今天使用dedecms织梦开源系统做企业网站,要实现在搜索页面里调用推荐新闻的,但是dedecms织梦在搜索页面里不可以直接使用以下代码调用文章的:

1. {dede:arclist flag='c' titlelen=42 row=6} 
2. [field:title/]  
3. [field:description function='cn_substr(@me,80)'/]... 
4. {/dede:arclist} 

如是笔者硬是把搜索页面的内核代码完全的看了一遍,终于实现了搜索页面调用“推荐文章”.

为什么搜索页面不能调用新闻呢,下面我来告诉大家,找到arc.searchview.class.php文件,看以下代码:

1. function Display() 
2.     { 
3.  
4.         foreach($this->dtp->CTags as $tagid=>$ctag) 
5.         { 
6.             $tagname = $ctag->GetName(); 
7.             if($tagname=="list") 
8.             { 
9.                 $limitstart = ($this->PageNo-1) * $this->PageSize; 
10.                 $row = $this->PageSize; 
11.                 if(trim($ctag->GetInnerText())=="") 
12.                 { 
13.                     $InnerText = GetSysTemplets("list_fulllist.htm"); 
14.                 } 
15.                 else 
16.                 { 
17.                     $InnerText = trim($ctag->GetInnerText()); 
18.                 } 
19.                 $this->dtp->Assign($tagid, 
20.                 $this->GetArcList($limitstart, 
21.                 $row, 
22.                 $ctag->GetAtt("col"), 
23.                 $ctag->GetAtt("titlelen"), 
24.                 $ctag->GetAtt("infolen"), 
25.                 $ctag->GetAtt("imgwidth"), 
26.                 $ctag->GetAtt("imgheight"), 
27.                 $this->ChannelType, 
28.                 $this->OrderBy, 
29.                 $InnerText, 
30.                 $ctag->GetAtt("tablewidth")) 
31.                 ); 
32.             } 
33.             else if($tagname=="pagelist") 
34.             { 
35.                 $list_len = trim($ctag->GetAtt("listsize")); 
36.                 if($list_len=="") 
37.                 { 
38.                     $list_len = 3; 
39.                 } 
40.                 $this->dtp->Assign($tagid,$this->GetPageListDM($list_len)); 
41.             } 
42.             else if($tagname=="likewords") 
43.             { 
44.                 $this->dtp->Assign($tagid,$this->GetLikeWords($ctag->GetAtt('num'))); 
45.             } 
46.             else if($tagname=="hotwords") 
47.             { 
48.                 $this->dtp->Assign($tagid,lib_hotwords($ctag,$this)); 
49.             } 
50.             else if($tagname=="field") 
51.             { 
52.                 //类别的指定字段 
53.                 if(isset($this->Fields[$ctag->GetAtt('name')])) 
54.                 { 
55.                     $this->dtp->Assign($tagid,$this->Fields[$ctag->GetAtt('name')]); 
56.                 } 
57.                 else 
58.                 { 
59.                     $this->dtp->Assign($tagid,""); 
60.                 } 
61.             } 
62.             else if($tagname=="channel") 
63.             { 
64.                 //下级频道列表 
65.                 if($this->TypeID>0) 
66.                 { 
67.                     $typeid = $this->TypeID; $reid = $this->TypeLink->TypeInfos['reid']; 
68.                 } 
69.                 else 
70.                 { 
71.                     $typeid = 0; $reid=0; 
72.                 } 
73.                 $GLOBALS['envs']['typeid'] = $typeid; 
74.                 $GLOBALS['envs']['reid'] = $typeid; 
75.                 $this->dtp->Assign($tagid,lib_channel($ctag,$this)); 
76.             }//End if 
77.       elseif($tagname=="arclist")//这是笔者自己加的代码只要加上这行代码我们就能调用“acrlist”标签 
78.      { 
79.      
80.       MakeOneTag($this->dtp,$this); 
81.      }//开源软件:phpfensi.com 
82.         } 
83.         global $keyword,  $oldkeyword; 
84.         if(!emptyempty($oldkeyword)) $keyword = $oldkeyword; 
85.         $this->dtp->Display(); 
86.     } 

只要把代码中加注释的那段语句加入arc.searchview.class.php文件里就可以实现搜索页面调用文章.
