This article mainly introduces how to solve the problem that the universal label loop can not be input into URL in Weaving Dream Dedecms, which has a certain reference value and can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Universal label loop is free to call any table in the dedecms data label, so called universal tag but today in the use of loop found that we commonly used arcurl is empty, meaning that url does not have that is equal to the tag is not, I will come to you to solve this problem.

First, let's take a look at the official description of the loop tag.

Tag name: loop

Function description: call the data label of any table

Scope of application: global tag

The basic syntax is as follows:

{dede:loop table='dede_archives' sort='' row='4' if=''} [field:title/] {/ dede:loop}

Tag attributes:

Table: query table name

Sort: fields used for sorting

Row: the number of results returned

If: the condition of query

According to this, I wrote a simple example, the code is as follows:

{dede:loop table='dede_archives' sort='' row='4' if=''} [field:title/] {/ dede:loop} / / output result Hello dedecms

You will notice that if href='' is empty, there is no url address, so this tag is useless for me. Baidu has found a solution.

1. Open Include/common.func.php, find line 54, and add a function code here as follows:

Function IDReturnURL ($ID) {/ / lonely global $dsql; $query = "Select arc.*,tp.typedir,tp.typename,tp.corank,tp.isdefault, tp.defaultname,tp.namerule,tp.moresite,tp.siteurl,tp.sitepath from dede_archives arc left join dede_arctype tp on arc.typeid=tp.id where arc.id =". $ID;$row = $dsql- > GetOne ($query) $ReturnURL = GetFileUrl ($row ['id'], $row [' typeid'], $row ['senddate'], $row [' title'], $row ['ismake'], $row [' arcrank'], $row ['namerule'], $row [' typedir'], $row ['money'], $row [' filename'], $row ['moresite'], $row [' siteurl'], $row ['sitepath']); return $ReturnURL;}

two。 The way we write the call in the template has also changed. The code is as follows:

{dede:loop table='dede_archives' sort='' row='4' if=''} [field:title function=cn_substrR (@ me,44) /] {/ dede:loop}

The problem has been solved perfectly, and the same is true when you want to use custom sql tags.

In fact, the [field:arcurl/] tag is replaced by [field:id function=IDReturnURL (@ me) /]. The core of my solution to this problem is [field:id function=IDReturnURL (@ me) /] and IDReturnURL.

Later, I thought about it, so I went on to find an arclist tag, the code is as follows:

{dede:arclist flag='h' typeid='' row='' col='' titlelen='' infolen='' imgwidth='' imgheight='' listtype='' orderby='' keyword='' limit='0,1'} [field:title/] {/ dede:arclist}

So we can use the following code directly:

{dede:arclist row='10' titlelen='24' orderby='pubdate' idlist='' col='2'} [field:textlink/] ([field:pubdate function=MyDate ('mmurdongjie) /]) {/ dede:arclist}

It can be solved.

Thank you for reading this article carefully. I hope the editor will share how to solve the problem that the omnipotent tag loop in Weaving Dream Dedecms can not enter URL. At the same time, I also hope that you can support it, pay attention to the industry information channel, and find out if you encounter problems. Detailed solutions are waiting for you to learn!
