织梦dedecms怎么调用三级及多级栏目嵌套

本文介绍了织梦dedecms怎么调用三级及多级栏目嵌套,解决办法:打开这个文件channel.lib.php,在里面添加教程给出的代码,然后在前端调用教程给出的代码就可以了。

织梦dedecms怎么调用三级及多级栏目嵌套?以前小编介绍过循环调用二级三级多级子栏目的方法,今天再来说说织梦多级栏目嵌套的方法。

将三级目录全部显示出来,而系统的channel标签只能获取下级分类,所以就报改了channel.lib.php这个文件,让他支持多级栏目嵌套。

代码如下:

<?php function lib_channel(&$ctag,&$refObj) {

global $_sys_globals,$envs,$dsql;

$attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|";

FillAttsDefault($ctag->CAttribute->Items,$attlist);

extract($ctag->CAttribute->Items, EXTR_SKIP);

$innertext = $ctag->GetInnerText();

if(empty($typeid) && $envs['typeid']!=0)

{

$typeid = $envs['typeid'];

$reid = $envs['reid'];

}else{

$reid=0;

}

if($type==''||$type=='sun') $type="son";

if($innertext=='') $innertext = GetSysTemplets("channel_list.htm");

if($reid==0 && $typeid>0)

{

$dbrow = $dsql->GetOne("Select reid From net_arctype where id='$typeid' ");

if(is_array($dbrow)) $reid = $dbrow['reid'];

}

$likeType = '';

if($type=='top')

{

$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description

From net_arctype where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row";

}

else if($type=="son")

{

//if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];

if($typeid==0) {

return '';

}

$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description

From net_arctype where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";

}

else if($type=="self")

{

if($reid==0) {

return '';

}

$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description

From `net_arctype` where reid='$reid' And ishidden<>1 order by sortrank asc limit 0,$row";

}

//And id<>'$typeid'

$dtp2 = new DedeTagParse();

$dtp2->SetNameSpace("field","[","]");

$dtp2->LoadSource($innertext);

$dsql2 = clone $dsql;

$dsql->SetQuery($sql);

$dsql->Execute();

$line = $row;

$GLOBALS['autoindex'] = 0;

for($i=0;$i < $line;$i++)

{

if($col>1) $likeType .= "<dl>\r\n";

for($j=0;$j<$col;$j++)

{

if($col>1) $likeType .= "<dd>\r\n";

if($row=$dsql->GetArray())

{

if($type=='self' && $row['id']==$typeid) //处理同级栏目中,当前栏目的样式

{

if($currentstyle!='')

{

$linkOkstr = $currentstyle;

$row['typelink'] = GetOneTypeUrlA($row);

$linkOkstr = str_replace("~typelink~",$row['typelink'],$linkOkstr);

$linkOkstr = str_replace("~typename~",$row['typename'],$linkOkstr);

$likeType .= $linkOkstr;

}

}else

{

$row['typelink'] = $row['typeurl'] = GetOneTypeUrlA($row);

if(is_array($dtp2->CTags))

{

foreach($dtp2->CTags as $tagid=>$ctag){

if(isset($row[$ctag->GetName()]))

{

$dtp2->Assign($tagid,$row[$ctag->GetName()]);

}

elseif (preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))

{

$dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql2));

}

}

}

$likeType .= $dtp2->GetResult();

}

}

if($col>1) $likeType .= "</dd>\r\n";

$GLOBALS['autoindex']++;

}//Loop Col

if($col>1)

{

$i += $col - 1;

$likeType .= "    </dl>\r\n";

}

}//Loop for $i

reset($dsql2);

$dsql->FreeResult();

return $likeType; } function lib_channel_son($ctag,$typeid = 0,$dsql2) {

$attlist = "row|100,col|1,currentstyle|";

FillAttsDefault($ctag->CAttribute->Items,$attlist);

extract($ctag->CAttribute->Items, EXTR_SKIP);

$innertext = $ctag->GetInnerText();

$dsql3 = clone $dsql2;

$likeType = '';

//if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];

if($typeid==0) {

return '';

}

$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description

From net_arctype where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";

//And id<>'$typeid'

$dtp2 = new DedeTagParse();

$dtp2->SetNameSpace("field","[","]");

$dtp2->LoadSource($innertext);

$dsql2->SetQuery($sql);

$dsql2->Execute();

$line = $row;

for($i=0;$i < $line;$i++)

{

if($col>1) $likeType .= "<dl>\r\n";

for($j=0;$j<$col;$j++)

{

if($col>1) $likeType .= "<dd>\r\n";

if($row=$dsql2->GetArray())

{

$row['typelink'] = $row['typeurl'] = GetOneTypeUrlA($row);

if(is_array($dtp2->CTags))

{

foreach($dtp2->CTags as $tagid=>$ctag){

if(isset($row[$ctag->GetName()]))

{

$dtp2->Assign($tagid,$row[$ctag->GetName()]);

}

elseif (preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))

{

$dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql3));

}

}

}

$likeType .= $dtp2->GetResult();

}

if($col>1) $likeType .= "</dd>\r\n";

}//Loop Col  www.dede58.com

if($col>1)

{

$i += $col - 1;

$likeType .= "    </dl>\r\n";

}

}//Loop for $i

reset($dsql3);

$dsql2->FreeResult();

return $likeType; } ?>

将以上代码全部替换channel.lib.php文件内容后就可以了,附前端调用的示例:

{dede:channel type='top'} [field:typename/] <ul> [field:sonchannel0] <li><a href="[field:typelink/]">[field:typename/]</a></li> [field:sonchannel1] <li><a href="[field:typelink/]">---[field:typename/]</a></li> [field:sonchannel2] <li><a href="[field:typelink/]">===[field:typename/]</a></li> [field:sonchannel3] <li><a href="[field:typelink/]">===[field:typename/]</a></li> [/field:sonchannel3] [/field:sonchannel2] [/field:sonchannel1] [/field:sonchannel0] </ul> {/dede:channel}

这样就可以使用了。
