dedecms独立模型分页功能的完善

来源:互联网 发布:wap小说网站源码 编辑:程序博客网 时间:2024/05/06 10:34

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:

1
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:
