上一主題/下一主題的實(shí)現(xiàn)
Jun 08, 2016 pm 05:33 PM
第一種方法：定義通用函數(shù)
function shownext(){
global $thisid;
$query="select * from TABLE_NAME where id>$thisid order by id limit 1";
$result=mysql_query($query);
if($result=0){
echo "已經(jīng)是第一個(gè)主題了";
}else{
if($row=mysql_fetch_array($result))
$nextid=$row["id"];
echo "下一主題";
}
}
function showpre(){
global $thisid;
$query="select * from TABLE_NAME where id
$result=mysql_query($query);
if($result=0){
echo "已經(jīng)是最后一個(gè)主題了";
}else{
if($row=mysql_fetch_array($result))
$preid=row["id"];
echo "上一主題";
}
}
這里的 $thisid 為當(dāng)前主題的id
第二種方法：假設(shè)有一個(gè)主題鏈接為 (當(dāng)前id為100)
detail.php?id=100&action=pre
或者
detail.php?id=100&action=next
然后在主題顯示頁(yè)面detail.php取記錄時(shí)使用如下條件語(yǔ)句
switch($acttion) {
case 'next':
$sql = "select * from table where id > $id limit 0,1";
break;
case 'prev':
$sql = "select * from table where id
break;
default:
$sql = "select * from table where id = $id";
}
