dedecms独立模型分页功能的完善

发表日期:2017-11 文章编辑:小灯 浏览次数:3075

dedecms其实在架构方面没什么问题,但是估计里面有些功能是新手做的吧,有很多待完善的地方,比如分页功能,从代码可以直接看出当时的负责人有敷衍了事的心里。

dede的分页如果有两个页码显示的话,无法显示出总的文章数,举个例子:

在普通文章模型下面,列表的分页是这样的:

但是在独立模型中就成了这样了

最后面的共*页*条的信息不见了,相信遇到这个问题的同学首先想到的是自己哪里用错了,其实不是,dede独立模型这里的代码是偷工减料了的。处理独立模型列表的代码在arc.sglistview.class.php中,我们比较下同样负责显示分页的代码段,独立模型和普通模型中有什么区别:

普通文章模型:

/*** 获取动态的分页列表** @access public* @param string $list_len 列表宽度* @param string $list_len 列表样式* @return string*/function GetPageListDM($list_len,$listitem="index,end,pre,next,pageno"){global $cfg_rewrite;$prepage = $nextpage = '';$prepagenum = $this->PageNo-1;$nextpagenum = $this->PageNo+1;if($list_len=='' || preg_match("/[^0-9]/", $list_len)){$list_len=3;}$totalpage = ceil($this->TotalResult/$this->PageSize);if($totalpage<=1 && $this->TotalResult>0){return "<li><span class=\"pageinfo\">共 1 页/".$this->TotalResult." 条记录</span></li>\r\n";}if($this->TotalResult == 0){return "<li><span class=\"pageinfo\">共 0 页/".$this->TotalResult." 条记录</span></li>\r\n";}$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>页<strong>".$this->TotalResult."</strong>条</span></li>\r\n";$purl = $this->GetCurUrl();// 如果开启为静态,则对规则进行替换if($cfg_rewrite == 'Y'){$nowurls = preg_replace("/\-/", ".php?", $purl);$nowurls = explode("?", $nowurls);$purl = $nowurls[0];}$geturl = "tid=".$this->TypeID."&TotalResult=".$this->TotalResult."&";$purl .= '?'.$geturl;$optionlist = '';//$hidenform = "<input type='hidden' name='tid' value='".$this->TypeID."'>\r\n";//$hidenform .= "<input type='hidden' name='TotalResult' value='".$this->TotalResult."'>\r\n";//获得上一页和下一页的链接if($this->PageNo != 1){$prepage.="<li><a href='".$purl."PageNo=$prepagenum'>上一页</a></li>\r\n";$indexpage="<li><a href='".$purl."PageNo=1'>首页</a></li>\r\n";}else{$indexpage="<li><a>首页</a></li>\r\n";}if($this->PageNo!=$totalpage && $totalpage>1){$nextpage.="<li><a href='".$purl."PageNo=$nextpagenum'>下一页</a></li>\r\n";$endpage="<li><a href='".$purl."PageNo=$totalpage'>末页</a></li>\r\n";}else{$endpage="<li><a>末页</a></li>\r\n";}//获得数字链接$listdd="";$total_list = $list_len * 2 + 1;if($this->PageNo >= $total_list){$j = $this->PageNo-$list_len;$total_list = $this->PageNo+$list_len;if($total_list>$totalpage){$total_list=$totalpage;}}else{$j=1;if($total_list>$totalpage){$total_list=$totalpage;}}for($j;$j<=$total_list;$j++){if($j==$this->PageNo){$listdd.= "<li class=\"thisclass\"><a>$j</a></li>\r\n";}else{$listdd.="<li><a href='".$purl."PageNo=$j'>".$j."</a></li>\r\n";}}$plist = '';if(preg_match('/index/i', $listitem)) $plist .= $indexpage;if(preg_match('/pre/i', $listitem)) $plist .= $prepage;if(preg_match('/pageno/i', $listitem)) $plist .= $listdd;if(preg_match('/next/i', $listitem)) $plist .= $nextpage;if(preg_match('/end/i', $listitem)) $plist .= $endpage;if(preg_match('/option/i', $listitem)) $plist .= $optionlist;if(preg_match('/info/i', $listitem)) $plist .= $maininfo;if($cfg_rewrite == 'Y'){$plist = str_replace('.php?tid=', '-', $plist);$plist = str_replace('&TotalResult=', '-', $plist);$plist = preg_replace("/&PageNo=(\d+)/i",'-\\1.html',$plist);}return $plist;}

独立模型:

/*** 获取动态的分页列表** @access public* @param int $list_len 列表宽度* @param string $listitem 列表样式* @return string*/function GetPageListDM($list_len,$listitem="index,end,pre,next,pageno"){global $nativeplace,$infotype,$keyword;if(empty($nativeplace)) $nativeplace = 0;if(empty($infotype)) $infotype = 0;if(empty($keyword)) $keyword = '';$prepage = $nextpage = '';$prepagenum = $this->PageNo - 1;$nextpagenum = $this->PageNo + 1;if($list_len=="" || preg_match("/[^0-9]/", $list_len)){$list_len=3;}$totalpage = ceil($this->TotalResult / $this->PageSize);if($totalpage<=1 && $this->TotalResult>0){return "<span class=\"pageinfo\">共1页/".$this->TotalResult."条记录</span>";}if($this->TotalResult == 0){return "<span class=\"pageinfo\">共0页/".$this->TotalResult."条记录</span>";}$purl = $this->GetCurUrl();$geturl = "tid=".$this->TypeID."&TotalResult=".$this->TotalResult."&nativeplace=$nativeplace&infotype=$infotype&keyword=".urlencode($keyword)."&";$hidenform = "<input type='hidden' name='tid' value='".$this->TypeID."' />\r\n";$hidenform = "<input type='hidden' name='nativeplace' value='$nativeplace' />\r\n";$hidenform = "<input type='hidden' name='infotype' value='$infotype' />\r\n";$hidenform = "<input type='hidden' name='keyword' value='$keyword' />\r\n";$hidenform .= "<input type='hidden' name='TotalResult' value='".$this->TotalResult."' />\r\n";$purl .= "?".$geturl;//获得上一页和下一页的链接if($this->PageNo != 1){$prepage.="<li><a href='".$purl."PageNo=$prepagenum'>上一页</a></li>\r\n";$indexpage="<li><a href='".$purl."PageNo=1'>首页</a></li>\r\n";}else{$indexpage="<li><a>首页</a></li>\r\n";}if($this->PageNo!=$totalpage && $totalpage>1){$nextpage.="<li><a href='".$purl."PageNo=$nextpagenum'>下一页</a></li>\r\n";$endpage="<li><a href='".$purl."PageNo=$totalpage'>末页</a></li>\r\n";}else{$endpage="<li><a>末页</a></li>";}//获得数字链接$listdd="";$total_list = $list_len * 2 + 1;if($this->PageNo >= $total_list){$j = $this->PageNo - $list_len;$total_list = $this->PageNo + $list_len;if($total_list > $totalpage){$total_list = $totalpage;}}else{$j=1;if($total_list > $totalpage){$total_list = $totalpage;}}for($j; $j <= $total_list; $j++){if($j == $this->PageNo){$listdd.= "<li class=\"thisclass\"><a>$j</a></li>\r\n";}else{$listdd.="<li><a href='".$purl."PageNo=$j'>".$j."</a></li>\r\n";}}$plist = $indexpage.$prepage.$listdd.$nextpage.$endpage;return $plist;}

仔细观察 普通模型中在28行左右的位置多了句$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>页<strong>".$this->TotalResult."</strong>条</span></li>\r\n";而在独立模型中则没有。

而且在最后,普通模型中将$maininfo的值加入了$plist字符串中。(更细节的地方是普通模型还判断了标签中是否有info属性来决定是否加入:

if(preg_match('/info/i', $listitem)) $plist .= $maininfo;

)独立模型中这些都省了。

要将独立模型修改过来很简单,不过“普通模型还判断了标签中是否有info属性来决定是否加入”这点我就不去实现了,这里不判断直接再任何情况下都加入maininfo:

/*** 获取动态的分页列表** @access public* @param int $list_len 列表宽度* @param string $listitem 列表样式* @return string*/function GetPageListDM($list_len,$listitem="index,end,pre,next,pageno"){global $nativeplace,$infotype,$keyword;if(empty($nativeplace)) $nativeplace = 0;if(empty($infotype)) $infotype = 0;if(empty($keyword)) $keyword = '';$prepage = $nextpage = '';$prepagenum = $this->PageNo - 1;$nextpagenum = $this->PageNo + 1;if($list_len=="" || preg_match("/[^0-9]/", $list_len)){$list_len=3;}$totalpage = ceil($this->TotalResult / $this->PageSize);if($totalpage<=1 && $this->TotalResult>0){return "<span class=\"pageinfo\">共1页/".$this->TotalResult."条记录</span>";}if($this->TotalResult == 0){return "<span class=\"pageinfo\">共0页/".$this->TotalResult."条记录</span>";}$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>页<strong>".$this->TotalResult."</strong>条</span></li>\r\n";$purl = $this->GetCurUrl();$geturl = "tid=".$this->TypeID."&TotalResult=".$this->TotalResult."&nativeplace=$nativeplace&infotype=$infotype&keyword=".urlencode($keyword)."&";$hidenform = "<input type='hidden' name='tid' value='".$this->TypeID."' />\r\n";$hidenform = "<input type='hidden' name='nativeplace' value='$nativeplace' />\r\n";$hidenform = "<input type='hidden' name='infotype' value='$infotype' />\r\n";$hidenform = "<input type='hidden' name='keyword' value='$keyword' />\r\n";$hidenform .= "<input type='hidden' name='TotalResult' value='".$this->TotalResult."' />\r\n";$purl .= "?".$geturl;//获得上一页和下一页的链接if($this->PageNo != 1){$prepage.="<li><a href='".$purl."PageNo=$prepagenum'>上一页</a></li>\r\n";$indexpage="<li><a href='".$purl."PageNo=1'>首页</a></li>\r\n";}else{$indexpage="<li><a>首页</a></li>\r\n";}if($this->PageNo!=$totalpage && $totalpage>1){$nextpage.="<li><a href='".$purl."PageNo=$nextpagenum'>下一页</a></li>\r\n";$endpage="<li><a href='".$purl."PageNo=$totalpage'>末页</a></li>\r\n";}else{$endpage="<li><a>末页</a></li>";}//获得数字链接$listdd="";$total_list = $list_len * 2 + 1;if($this->PageNo >= $total_list){$j = $this->PageNo - $list_len;$total_list = $this->PageNo + $list_len;if($total_list > $totalpage){$total_list = $totalpage;}}else{$j=1;if($total_list > $totalpage){$total_list = $totalpage;}}for($j; $j <= $total_list; $j++){if($j == $this->PageNo){$listdd.= "<li class=\"thisclass\"><a>$j</a></li>\r\n";}else{$listdd.="<li><a href='".$purl."PageNo=$j'>".$j."</a></li>\r\n";}}$plist = $indexpage.$prepage.$listdd.$nextpage.$endpage;;return $plist;}
