tx83织梦栏目(动态、静态)分页教程

在使用织梦DedeCms做小说站、图片站、影视站类型网站的时候,往往需要使用多个栏目来区分内容类型。

以小说站为例,一个栏目就是一部小说,栏目内发布文章是小说的各个章节,当栏目已经存在很多的时候,就需要用到分页,但是织梦官方别没有提供栏目分页的代码,本文教程课轻松实现栏目分页,也可扩展其他分页,例如会员分页,自定义表单分页等

打开 /include/arc.listview.class.php 有三处需要修改,找到 大概在248行

$ctag = $this->dtp->GetTag("page");

在它下面加入

if(!is_object($ctag))
{
$ctag = $this->dtp->GetTag("listsql");if(is_object($ctag))
{$this->addSql = " WHERE ishidden<>1 ";if($cfg_list_son=='N')
{if($this->CrossID=='') $this->addSql .= " AND (id='".$this->TypeID."') ";else $this->addSql .= " AND (id in({$this->CrossID},{$this->TypeID})) ";
}else
{
$sonids = GetSonIds($this->TypeID,$this->Fields['channeltype'],0);if(!preg_match("/,/", $sonids)) {$this->addSql .= " AND id = '$sonids' ";
}else {$this->addSql .= " AND id IN($sonids) ";
}
}
$sql = $ctag->GetAtt("sql");
$sql = preg_replace("/SELECT(.*?)FROM/is", " SELECT count(*) as dd FROM ", $sql);
$sql = preg_replace("/ORDER(.*?)SC/is", "", $sql);
$sql = $sql.$this->addSql;
$row = $this->dsql->GetOne($sql);if(is_array($row))
{$this->TotalResult = $row['dd'];
}else
{$this->TotalResult = 0;
}
}
}

找到

else if($ctag->GetName()=="pagelist")

在它上面加入

else if($ctag->GetName()=="listsql")
{
    $limitstart = ($this->PageNo-1) * $this->PageSize;
    $row = $this->PageSize;    if(trim($ctag->GetInnerText())=="")
    {
        $InnerText = GetSysTemplets("list_fulllist.htm");
    }    else
    {
        $InnerText = trim($ctag->GetInnerText());
    }    $this->dtp->Assign($tagid,    $this->GetSqlList(
    $limitstart,
    $row,
    $ctag->GetAtt("sql"),
    $InnerText
    ));
}

找到

function GetPageListST

在它上面加入

function GetSqlList($limitstart = 0, $row = 10, $sql = '', $innertext){    global $cfg_list_son;
    $innertext = trim($innertext);    if ($innertext == '')
    {
        $innertext = GetSysTemplets('list_fulllist.htm');
    }    //处理SQL语句
    $limitStr = " LIMIT {$limitstart},{$row}";
$sql = $sql.$this->addSql.$limitStr;    $this->dsql->SetQuery($sql);    $this->dsql->Execute('al');
    $t2 = ExecTime();    //echo $t2-$t1;
    $sqllist = '';    $this->dtp2->LoadSource($innertext);
    $GLOBALS['autoindex'] = 0;    //获取字段
    while($row = $this->dsql->GetArray("al"))
    {
$row['typeurl'] = GetTypeUrl($row['typeid'],MfTypedir($row['typedir']),$row['isdefault'],$row['defaultname'],
                    $row['ispart'],$row['namerule2'],$row['moresite'],$row['siteurl'],$row['sitepath']);
$row['typelink'] = GetOneTypeUrlA($row);
        $GLOBALS['autoindex']++;        if(is_array($this->dtp2->CTags))
        {            foreach($this->dtp2->CTags as $k=>$ctag)
            {                if($ctag->GetName()=='array')
                {                    //传递整个数组,在runphp模式中有特殊作用
                    $this->dtp2->Assign($k,$row);
                }                else
                {                    if(isset($row[$ctag->GetName()]))
                    {                        $this->dtp2->Assign($k,$row[$ctag->GetName()]);
                    }                    else
                    {                        $this->dtp2->Assign($k,'');
                    }
                }
            }
        }
        $sqllist .= $this->dtp2->GetResult();
    }//while
    $t3 = ExecTime();    //echo ($t3-$t2);
    $this->dsql->FreeResult('al');    return $sqllist;
}

 

栏目模板标签写法

<h2>栏目列表</h2><ul>
{dede:listsql sql="select * from dede_arctype" pagesize="10"}<li> 
<a href="[field:typelink/]">[field:typename/]</a>
<p>栏目描述:[field:description/]...</p>
</li>
{/dede:listsql}</ul><h2>栏目分页条</h2><ul class="pagelist">
{dede:pagelist listitem="info,index,end,pre,next,pageno,option" listsize="5"/}</ul>

pagesize="10"  每页显示10个栏目

[field:typelink/]  栏目链接

[field:typename/]    栏目名称

[field:其他字段/]   栏目其他自定义字段都可以直接调用
