PHP下拉列表分頁

?

$myurl = “index.php”

$pagestring .= ”  跳轉到\n select name=\”chg_go\” onchange=\”window.location.href='”.$myurl.”?page=’+this.value;\”\n”;

for($a=1;$a=$pagecount;$a++){

}

}

$pagestring .= ” /select\n 頁  /td\n/tr\n/table”;

關於PHP分頁

一個分頁函數，賦好值就可以使用了

/*

‘PID 頁面中的其它傳參連接

‘page 要顯示的頁碼

‘Vcount 總記錄數

‘Pnum 每頁記錄數

‘className 超連接樣式

*/

function ThePage($Pid,$page=1,$Vcount,$Pnum,$className){

$Pcount = ceil($Vcount/$Pnum);

if($page$Pcount) $page=$Pcount;

$StartPageNum=1;

while($StartPageNum+10=$page){

$StartPageNum=$StartPageNum+10;

}

$EndPageNum=$StartPageNum+9 ;

if($EndPageNum$Pcount) $EndPageNum=$Pcount;

$show = $show.”trtd colspan=’10’ bgcolor=” align=’right’ style=’padding-right:25px;padding-top:5px;’ class='”.$className.”‘”;

$show = $show.”共b”.$Pcount.”/b頁 共有b”.$Vcount.”/b記錄 第b”.$page.”/b頁 跳到第 [ “;

if($StartPageNum1) $show = $show.”a class='”.$className.”‘ href=’?”.$Pid.”page=”.($StartPageNum-1).”‘ title=’前十頁’font face=’webdings’7/font/a”;

for($go=$StartPageNum;$go=$EndPageNum;$go++){

if($go!=$page){

$show = $show.”a class='”.$className.”‘ href=’?”.$Pid.”page=”.$go.”‘”.$go.”/a”;

}else{

$show = $show.”b”.$go.”/b”;

}

$show = $show.” “;

}

if($EndPageNum$Pcount) $show = $show.”a class='”.$className.”‘ href=’?”.$Pid.”page=”.($EndPageNum+1).”‘ title=’下十頁’font face=’webdings’8/font/a”;

$show = $show.”] 頁”;

if($page!=1) $show = $show.”a class='”.$className.”‘ href=’?”.$Pid.”page=1′ 首頁/a a class='”.$className.”‘ href=’?”.$Pid.”page=”.($page-1).”‘上一頁/a”;

if($Pcount-$page!=0) $show = $show. “a class='”.$className.”‘ href=’?”.$Pid.”page=”.($page+1).”‘ 下一頁/a a class='”.$className.”‘ href=’?”.$Pid.”page=”.$Pcount.”‘尾頁/a”;

$show=$show.”/tr/td”;

return $show;

}

========================附帶一個使用例子=============================

?

//設置參數

$page = $_REQUEST[“page”];

if($page==””) $page = 1;

$T = $_GET[“T”];

if($T==””) $T = 1;

$Pid = “T=”.$T.””;

$wheresql = “where T = “.$T;

$recordListTable = “zc_news”;

$Pnum = 10;

$classname = “lwf”;

//以下不用修改

$rs = mysql_query(“select count(*) from `”.$recordListTable.”` $wheresql “);

$Vcount = @mysql_result($rs,0);

@mysql_free_result($rs);

$start = ($page – 1) * $Pnum;

$lastNum = $Vcount – ($page – 1) * $Pnum;

$limit = $lastNum $Pnum ? $Pnum : $lastNum;

$rs = mysql_query(“select * from `”.$recordListTable.”` $wheresql order by orderid desc,ID desc LIMIT $start,$limit”);

while($ary = mysql_fetch_array($rs)){

php下拉列表能多選么

下拉列表多選不是php的功能,下面的代碼就是多選的select了，但是多選後就不是下拉菜單了，下拉菜單無法多選。

select name=”education” id=”education” multiple=”multiple” size=”3″

       option value=”1″高中/option

       option value=”2″大學/option

       option value=”3″博士/option

/select
