dedecms獨立模型分頁功能的完好
dedecms事實上在架構方面沒什麽問題,可是預計裏面有些功能是新手做的吧,有非常多待完好的地方,比方分頁功能。從代碼能夠直接看出當時的負責人有敷衍了事的心裏。
dede的分頁假設有兩個頁碼顯示的話,無法顯示出總的文章數,舉個樣例:
在普通文章模型以下,列表的分頁是這種:
可是在獨立模型中就成了這樣了
最後面的共*頁*條的信息不見了。相信遇到這個問題的同學首先想到的是自己哪裏用錯了,事實上不是,dede獨立模型這裏的代碼是偷工減料了的。處理獨立模型列表的代碼在arc.sglistview.class.php中,我們比較下相同負責顯示分頁的代碼段,獨立模型和普通模型中有什麽差別:
普通文章模型:

/** * 獲取動態的分頁列表 * * @access public * @param int $list_len 列表寬度 * @param string $listitem 列表樣式 * @return string */ function GetPageListDM($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 && $this->TotalResult>0) { return "<span class=\"pageinfo\">共1頁/".$this->TotalResult."條記錄</span>"; } if($this->TotalResult == 0) { return "<span class=\"pageinfo\">共0頁/".$this->TotalResult."條記錄</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; //獲得上一頁和下一頁的鏈接 if($this->PageNo != 1) { $prepage.="<li><a href=‘".$purl."PageNo=$prepagenum‘>上一頁</a></li>\r\n"; $indexpage="<li><a href=‘".$purl."PageNo=1‘>首頁</a></li>\r\n"; } else { $indexpage="<li><a>首頁</a></li>\r\n"; } if($this->PageNo!=$totalpage && $totalpage>1) { $nextpage.="<li><a href=‘".$purl."PageNo=$nextpagenum‘>下一頁</a></li>\r\n"; $endpage="<li><a href=‘".$purl."PageNo=$totalpage‘>末頁</a></li>\r\n"; } else { $endpage="<li><a>末頁</a></li>"; } //獲得數字鏈接 $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 $plist; }
細致觀察 普通模型中在28行左右的位置多了句$maininfo = "<li><span class=\"pageinfo\">共 <strong>{$totalpage}</strong>頁<strong>".$this->TotalResult."</strong>條</span></li>\r\n";而在獨立模型中則沒有。
並且在最後,普通模型中將$maininfo的值增加了$plist
字符串中。(更細節的地方是普通模型還推斷了標簽中是否有info屬性來決定是否增加:
1 |
if (preg_match( ‘/info/i‘ , $listitem)) $plist .= $maininfo;
|
)獨立模型中這些都省了。
要將獨立模型改動過來非常easy。只是“普通模型還推斷了標簽中是否有info屬性來決定是否增加”這點我就不去實現了,這裏不推斷直接再不論什麽情況下都增加maininfo:
