The website divides the region into provinces-cities-articles hierarchical structure according to needs, column home page What needs to be displayed is

The code is as follows:

{dede:channelarclist} <!--省显示--> 
<a href="">省级标题：{dede:field name=&#39;name&#39;/}</a> 
{dede:channel type=&#39;son&#39;} 
<a href="">市级标题：[field:name/]</a> 
{dede:arclist} 
该市文章{field:title/} 
{/dede:arclist} 
{/dede:channel} 
{/dede:channelarclist}

That is, the provincial columns are classified by cities and the article titles of each city are displayed. However, the {dede:channel} tag cannot be nested, so The {dede:arclist} tag will be output as it is. The solution:

The code is as follows:

$typeid = $row[&#39;id&#39;]; 
if((class_exists(&#39;PartView&#39;))) 
{ 
$pv = new PartView($typeid); 
$text = $likeType; 
$text= str_replace(array(&#39;{field&#39;, &#39;/}&#39;), array(&#39;[field&#39;, &#39;/]&#39;), $text); 
$pv->SetTemplet($text,&#39;string&#39;); 
$artlist = $pv->GetResult(); 
$likeType = $artlist; 
}

Copy after login

Find if($col>1) in /include/taglib/channel.lib.php $likeType .= "\r\n"; (v5.6 is 125 lines v5.7 is 156 lines) Add the above code to this sentence

The problem is solved.

Some people reported that after adding this code, the article page cannot be updated when it contains {dede:channel} {/dede:channel}, so you can look at the code and change it to this:

The code is as follows:

if($sanji) 
{ 
$typeid = $row[&#39;id&#39;]; 
if((class_exists(&#39;PartView&#39;))) 
{ 
$pv = new PartView($typeid); 
$text = $likeType; 
$text= str_replace(array(&#39;{field&#39;, &#39;/}&#39;), array(&#39;[field&#39;, &#39;/]&#39;), $text); 
$pv->SetTemplet($text,&#39;string&#39;); 
$artlist = $pv->GetResult(); 
$likeType = $artlist; 
} 
}

Copy after login

Then add $sanji = $ctag->GetAtt('sanji'); after global $dsql; at the beginning of the channel.lib.php file

When called, it becomes:

The code is as follows:

{dede:channelartlist} 
{dede:field name=&#39;typeurl&#39;/} {dede:field name=&#39;typename&#39;/} //外框架 
{dede:channel type=&#39;sun&#39; sanji=&#39;1&#39;}//子框架 
<h3><a href="[field:typelink/]" target="_blank">[field:typename/]</a></h3> 
{dede:arclist row=&#39;5&#39; titlelen=&#39;39&#39;} //调用文章 
连接： {field:arcurl/} 
标题： {field:title/} 
{/dede:arclist} 
{/dede:channel} 
{/dede:channelartlist}

Copy after login

Problem solved.
