DEDECMS homepage calls the implementation of level 1 and level 2 topics cyclically

As a very popular CMS website system in China, DEDECMS is favored by the majority of webmasters. Many people use DEDE to build websites. When using dede to build a website, some functions need to be changed or called according to your preferences. In dede's official documentation, there is no specific description about how to call the first-level and second-level functions cyclically.

Today, shadow will share with you what webmasters and friends need to achieve the purpose of optimizing website navigation by calling level 1 and level 2 topics cyclically on the homepage of the dede website.

Let's start with the following:

On the homepage, how does one implement the loop call of level 1 and level 2 columns?

In many templates, we will see code similar to the following. This is the code snippet used to call all sub-categories under a specific category cyclically.

--------------------------------

{Dede: channelartlist typeid = '3' row = '4 '}

<Strong> <a href = "{dede: field name = 'typeurl'/}"> {dede: field name = 'typename'/} </a>

 

 

 

<A rel = "external nofollow" href = "[field: arcurl/]"> [field: title/]

 

 

{/Dede: arclist}

{/Dede: channelartlist}

--------------------------------

From this we can see that this is a bit similar to the first-level and second-level columns of loop calls, but it has some functional differences. We can perform secondary modifications on this basis to achieve the objective of calling level-1 and level-2 columns cyclically.

The following is the modified implementation method:

--------------------------------

{Dede: channelartlist}

<Dl class = "ilistdh">

<Dt class = "itopdh"> <a href = "{dede: field name = 'typeurl'/}"> {dede: field name = 'typename'/} </a>

<Dd class = "isondh">

{Dede: channel type = 'sun' row = '3'} // here row = 3 only calls three subcolumns

<A rel = "external nofollow" href = "[field: typeurl/]"> [field: typename/] </a>

{/Dede: channel}

</Dd>

</Dl>

{/Dede: channelartlist}

--------------------------------

The above code is the call code of the Shadow website. You can modify it based on your actual situation and then beautify it through css.
