分頁一共有提供了四種形式,固然也能夠本身進行擴展css
$this->set('limit', 10); //limit 每頁顯示的條數 $this->set('total', 100); //total 總條數 $this->set('curpage', 1); //curpage 當前頁
<div class="fr y-page"> <?php echo $this->Page->show($limit, $total, $curpage, 5, "/Pages/display/param1:$param1/param2:$param2/curpage:",2 ); ?> </div>
其中能夠加多個參數,形式: param1:$param1/param2:$param2 條件參數html
固然到這步了,還缺乏樣式,下面爲樣式 代碼 (能夠本身進行調整)。segmentfault
.fr { float: right; } .y-page { line-height: 18px; margin: 20px 0 10px; } .y-page .y-width { padding: 0 14px; } .y-page .y-act-c { color: #999999; } .y-page span { float: left; margin-right: 10px; margin-top: 3px; } .y-page .y-width { padding: 0 14px; } .y-page a { background: none repeat scroll 0 0 #FFFFFF; border: 1px solid #CCCCCC; color: #333333; float: left; font-size: 12px; height: 19px; line-height: 18px; margin-right: 5px; overflow: hidden; padding: 0 8px; text-align: center; } a { color: #2071BD; text-decoration: none; } a:hover{ color: #E00000; text-decoration: underline; }
完成後,一個簡單的分頁就出來了
