收藏一個php用的一個頁碼按鈕類

?

調用

$pagenav = new pagenav(); $pagenav -> pageinit(頁面地址無參數的,總頁數,所在頁面,除1和總數中間的數量，我測試為7);

PHP code

class pagenav{public $pageurl;public $totalpage;public $inpage;public $navcenter;function pageinit($pageurl,$totalpage,$inpage,$navcenter){$this->pageurl = $pageurl;$this->totalpage = $totalpage;$this->inpage = $inpage;$this->navcenter = $navcenter;echo "<strong style='border: 1px #7099cc solid ;padding: 5px;line-height: 30px;height: 30px;padding-left: 15px;margin-right: 10px'>翻頁 ? </strong>";$this->showbof();$this->showcenter();$this->showeof();} function showbof(){if($this->inpage!=1){echo "<a href='";echo $this->pageurl;echo "' class='pagenavoff'>";echo 1;if($this->inpage > ceil($this->navcenter / 2) + 1 and $this->totalpage > 9){echo "...";}echo "</a>";}else{echo "<strong class='pagenavon'>1</strong>";}} function showcenter(){ $center_bofnum = $this->inpage - ceil($this->navcenter / 2) + 1;if($this->inpage - ceil($this->navcenter / 2) < 1){$center_bofnum = 2;} $center_eofnum = $center_bofnum + $this->navcenter;if( $center_eofnum > $this->totalpage - 1){$center_eofnum = $this->totalpage ;} if( $center_eofnum - $center_bofnum < 7 and $this->inpage - ceil($this->navcenter / 2) > 2){ $center_bofnum = $center_eofnum - $this->navcenter; }while($center_bofnum < $center_eofnum ){echo " ";
if($this->inpage!=$center_bofnum){echo "<a href='"; echo $this->pageurl."?page=".$center_bofnum;echo "' class='pagenavoff'>";echo $center_bofnum;echo "</a>";}else{echo "<strong class='pagenavon'>";echo $center_bofnum;echo "</strong>";}$center_bofnum++;}} function showeof(){if($this->totalpage > 1){echo " ";
