    织梦dedecms5.7 动态导航下拉菜单代码实例

    本文介绍一个在dedecms5.7中实现动态导航下拉菜单的代码实例,供大家学习参考。

    1、修改include/taglib文件夹中的channel.lib.php文件,替换为如下内容:

    <?php

    /**

    * 动态导航下拉菜单

    * Edit www.niuqi.net

    * Date 2015-5-3

    */

    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 = $dsql->GetOne("Select reid From <a href="mailto:`dede_arctype">`dede_arctype</a>` where id='$typeid' ");

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

    }

    $likeType = '';

    if($type=='top')

    {

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

    From <a href="mailto:`dede_arctype">`dede_arctype</a>` 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,description

    From <a href="mailto:`dede_arctype">`dede_arctype</a>` 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,description

    From <a href="mailto:`dede_arctype">`dede_arctype</a>` 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,description

    From <a href="mailto:`dede_arctype">`dede_arctype</a>` 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;

    }

    ?>

    2、调用示例

    {dede:channel typeid='1'}

    <li>

    <a class="" href="[field:typeurl/]" title="">[field:typename/]

    <img src="***.gif" /></a>

    <div class="sub">

    <ul>

    [field:sonchannel0]<li><a href="[field:typeurl/]">[field:typename/]</a></li>[/field:sonchannel0]

    </ul>

    </div>

    </li>

    {/dede:channel}
