织梦CMS系统用dede:sql实现列表页分页方法

织梦技巧

将dede:list标签进行改造,使用SQL标签实现静态分页,在自定义表单调用的分页用他就很方便

例如织梦会员列表的模板标签写法

{dede:listsql sql="select * from 58pic_member" pagesize="10"}<li><a href="[field:id runphp=yes]$id=@me;$url=GetOneArchive($id);@me=$url['arcurl'][/field:id]"><img src="[field:litpic/]">[field:XX /]</a></li>{/dede:listsql}<!--分页-->{dede:pagelist/}

dedecms教程开始

打开include/arc.listview.class.php 找到

if(!is_object($ctag)){	$ctag = $this->dtp->GetTag("list");}

在下面加入

if(!is_object($ctag)){    $ctag = $this->dtp->GetTag("listsql");    if(is_object($ctag))    {        $cquery = $ctag->GetAtt("sql");        //$cquery = str_replace('~reid~',$this->ReID,$cquery); 这是另一个客户要求的获取url第2个参数才加的。        $cquery = preg_replace("/SELECT(.*?)FROM/is", " SELECT count(*) as dd FROM ", $cquery);        $cquery = preg_replace("/ORDER(.*?)SC/is", "", $cquery);        $row = $this->dsql->GetOne($cquery);        if(is_array($row))        {            $this->TotalResult = $row['dd'];        }        else        {            $this->TotalResult = 0;        }    }}

继续找到

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    ));}

最后找到

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}";    $sql = str_replace('~reid~',$this->ReID,$sql);        $this->dsql->SetQuery($sql . $limitStr);    $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"))    {        $GLOBALS['autoindex']++;        if(is_array($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;}

完成,注意代码放置的位置,有的是在上面有的是在下面。
