Dream weaving DEDECMS extension tag how to use?

Demonstration example of Dream Weaving DEDECMS extension tag

Recommended study: dream weaving cms

We can look at a sample tag: demotag.lib.php

If (! defined ('DEDEINC')) {exit ("Request Error!");} function lib_demotag (& $ctag,&$refObj) {global $dsql,$envs; $attlist= "row | 12 dsql,$envs; titlelen | 24"; FillAttsDefault ($ctag- > CAttribute- > Items,$attlist); extract ($ctag- > CAttribute- > Items, EXTR_SKIP); $revalue ='' / /-$revalue = 'Hello Wordword commands; / /-return $revalue;}? >

We will find that the tag works and outputs our content.

$revalue = 'Hello Wordword commands; $revalue. = "Row:". $row. "; TitleLen:". $titlelen

So we can see that this property has been created and assigned.

Next we can further modify the tag.

Function lib_writerarc ($ctag,&$refObj)

Then we can write query statements and related functions for dealing with the underlying template.

$revalue =''; $innertext = $ctag- > GetInnerText (); $ctp = new DedeTagParse (); $ctp- > SetNameSpace ('field',' [',']'); $sql = "SELECT * FROM dede_archives WHERE writer=' {$refObj- > Fields ['writer']}' limit 0, $row"; $dsql- > Execute ('me',$sql); while ($rs = $dsql- > GetArray (' me')) {$rs ['title'] = cn_substr ($rs [' title'], $titlelen); $ctp- > LoadSource ($innertext) Foreach ($ctp- > CTags as $tagid= > $ctag) {if (! emptyempty ($rs [strtolower ($ctag- > GetName ()])) {$ctp- > Assign ($tagid,$rs [$ctag- > GetName ()]);} $revalue. = $ctp- > GetResult ();}

Finally, the value return $revalue is returned

The whole document is as follows:

If (! defined ('DEDEINC')) {exit ("Request Error!");} function lib_writerarc (& $ctag,&$refObj) {global $dsql,$envs; $attlist= "row | 12 dsql,$envs; titlelen | 24"; FillAttsDefault ($ctag- > CAttribute- > Items,$attlist); extract ($ctag- > CAttribute- > Items, EXTR_SKIP); $revalue =''; $innertext = $ctag- > GetInnerText (); $ctp = new DedeTagParse (); $ctp- > SetNameSpace ('field',' [',']') $sql = "SELECT * FROM dede_archives WHERE writer=' {$refObj- > Fields ['writer']}' limit 0, $row"; $dsql- > Execute ('me',$sql); while ($rs = $dsql- > GetArray (' me')) {$rs ['title'] = cn_substr ($rs [' title'], $titlelen); $ctp- > LoadSource ($innertext); foreach ($ctp- > CTags as $tagid= > $ctag) {if (! emptyempty ($rs strtolower ($ctag- > GetName () {$GetName > ctp- ($ctp- [$GetName > ctp- ()]) }} $revalue. = $ctp- > GetResult ();} return $revalue;}? >
