打开织梦include/arc.listview.class.php，找到代码：
if(!is_object($ctag)) { $ctag = $this->dtp->GetTag("list"); } 这一段，在其后添加如下代码：
if(!is_object($ctag)){$ctag = $this->dtp->GetTag("listsql");if (is_object($ctag)){$cquery = $ctag->GetAtt("sql");$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;}}}//end |
然后找到代码：
if($ctag->GetName()=="list"){$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->GetArcList($limitstart,$row,$ctag->GetAtt("col"),$ctag->GetAtt("titlelen"),$ctag->GetAtt("infolen"),$ctag->GetAtt("imgwidth"),$ctag->GetAtt("imgheight"),$ctag->GetAtt("listtype"),$ctag->GetAtt("orderby"),$InnerText,$ctag->GetAtt("tablewidth"),$ismake,$ctag->GetAtt("orderway")));} |
这一段，在其后添加如下代码：
else if($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));}//end |
最后找到function GetArcList这个函数，在其后添加一个可以通过传入sql参数获取指定数据源的方法，代码如下：
/*** 通过listsql标签中sql属性传入的参数来获得一个单列的文档列表* */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}";$this->dsql->SetQuery($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;}//end |
总共就添加三段代码，每一段代码基本都参考它紧接着的上面那段原始代码，而无需改变它原来任何一个地方的代码，应该算是比较完美了，接下来在模板文件中的使用方法就跟一开始思路中所提到的那样，分页标签依旧沿用原来的，调用范例：
{dede:listsql sql='select ID,post_title from wp_posts' pagesize='10'}
