  • 修改channel.lib.php实现DedeCMS多级栏目嵌套

    前段时间做了个产品站,产品栏目分类为三级目录,客户想在前端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) $likeType .= "</dd>\\r\\n";
    }//Loop Col
    if($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}
