您提到的“织梦”和“dede:sql”可能指的是织梦CMS(Dreamweaver)、以及该系统中的SQL相关操作。如果您需要在织梦CMS中实现列表页分页的教程方法
例如:在模板标签上实现如下功能
{dede:listsql sql='SELECT * FROM dede_aq_redirect ORDER BY id' return='items' pagesize="2" }
[field:title/]
{/dede:listsql}
实现方案如下 打开include/arc.listview.class.php 找到 :
在该文件找到如下代码:
if(!is_object($ctag))
{
$ctag = $this->dtp->GetTag("list");
}
在下面增加以下代码:
if(!is_object($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
{
$this->TotalResult = 0;
}
}
}
2. 该文件找到以下代码:
else if($ctag->GetName()=="pagelist")
在上面增加以下代码
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"),
$InnerText
));
}
3. 该文件找到以下代码:
function GetPageListST(
在它上面加入以下代码
function GetSqlList($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;
}
修改完成,可以试试模板上自定义标签功能
