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
