1 if(!is_object($ctag))2 {3 $ctag = $this->dtp->GetTag("list");4 }这一段,在其后添加如下代码:
01 if(!is_object($ctag))02 {03 $ctag = $this->dtp->GetTag("listsql");04 if (is_object($ctag))05 {06 $cquery = $ctag->GetAtt("sql");07 $cquery = preg_replace("/SELECT(.*?)FROM/is", " SELECT count(*) as dd FROM ", $cquery);08 $cquery = preg_replace("/ORDER(.*?)SC/is", "", $cquery);09 $row = $this->dsql->GetOne($cquery);10 if(is_array($row))11 {12 $this->TotalResult = $row['dd'];13 }14 else15 {16 $this->TotalResult = 0;17 }18 }19 }20 //end然后找到:
01 if($ctag->GetName()=="list")02 {03 $limitstart = ($this->PageNo-1) * $this->PageSize;04 $row = $this->PageSize;05 if(trim($ctag->GetInnerText())=="")06 {07 $InnerText = GetSysTemplets("list_fulllist.htm");08 }09 else10 {11 $InnerText = trim($ctag->GetInnerText());12 }13 $this->dtp->Assign($tagid,14 $this->GetArcList(15 $limitstart,16 $row,17 $ctag->GetAtt("col"),18 $ctag->GetAtt("titlelen"),19 $ctag->GetAtt("infolen"),20 $ctag->GetAtt("imgwidth"),21 $ctag->GetAtt("imgheight"),22 $ctag->GetAtt("listtype"),23 $ctag->GetAtt("orderby"),24 $InnerText,25 $ctag->GetAtt("tablewidth"),26 $ismake,27 $ctag->GetAtt("orderway")28 )29 );30 }这一段,在其后添加如下代码:
01 else if($ctag->GetName()=="listsql")02 {03 $limitstart = ($this->PageNo-1) * $this->PageSize;04 $row = $this->PageSize;05 if(trim($ctag->GetInnerText())=="")06 {07 $InnerText = GetSysTemplets("list_fulllist.htm");08 }09 else10 {11 $InnerText = trim($ctag->GetInnerText());12 }13 $this->dtp->Assign($tagid,14 $this->GetSqlList(15 $limitstart,16 $row,17 $ctag->GetAtt("sql"),18 $InnerText19 )20 );21 }22 //end最后找到function GetArcList这个方法,在其后添加一个可以通过传入sql参数获取指定数据源的方法,代码如下:
01 /**02 * 通过listsql标签中sql属性传入的参数来获得一个单列的文档列表03 * */04 function GetSqlList($limitstart = 0, $row = 10, $sql = '', $innertext){05 06 global $cfg_list_son;07 $innertext = trim($innertext);08 09 if ($innertext == '') {10 $innertext = GetSysTemplets('list_fulllist.htm');11 }12 //处理SQL语句13 $limitStr = " LIMIT {$limitstart},{$row}";14 15 $this->dsql->SetQuery($sql . $limitStr);16 $this->dsql->Execute('al');17 $t2 = ExecTime();18 19 //echo $t2-$t1;20 $sqllist = '';21 $this->dtp2->LoadSource($innertext);22 $GLOBALS['autoindex'] = 0;23 24 //获取字段25 while($row = $this->dsql->GetArray("al")) {26 27 $GLOBALS['autoindex']++;28 29 if(is_array($this->dtp2->CTags))30 {31 foreach($this->dtp2->CTags as $k=>$ctag)32 {33 if($ctag->GetName()=='array')34 {35 //传递整个数组,在runphp模式中有特殊作用36 $this->dtp2->Assign($k,$row);37 }38 else39 {40 if(isset($row[$ctag->GetName()]))41 {42 $this->dtp2->Assign($k,$row[$ctag->GetName()]);43 }44 else45 {46 $this->dtp2->Assign($k,'');47 }48 }49 }50 }51 52 $sqllist .= $this->dtp2->GetResult();53 54 }//while55 56 $t3 = ExecTime();57 //echo ($t3-$t2);58 $this->dsql->FreeResult('al');59 60 return $sqllist;61 }62 //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:
1 {dede:listsql sql='select ID,post_title from wp_posts' pagesize='10'}2 <li><a href="[field:ID /].html">[field:post_title /]</a></li>3 {/dede:listsql}4 <!--分页-->5 {dede:pagelist listsize='2' listitem='index pre pageno next end '/}注:以上解决方案适用于dedecms5.6-5.7版本。
