我有多个页面传递两个值,值为Sname& SID ..
我用过
$sql = "SELECT s.Sname, e.PID , s.SID
from student AS s
INNER JOIN evaluator AS e
WHERE (e.EID1 = '$id' AND s.PID = e.PID) OR (e.EID2 = '$id' AND s.PID = e.PID)
GROUP BY s.Sname ";
$result = mysql_query ($sql, $connection);
echo "<tr><th>Student Name </th>";
echo "<td><select id='Sname' name='Sname' >";
echo "<option value='' selected='selected'>--</option> ";
while( $row = mysql_fetch_array($result))
{
echo "<option value='$row[SID]|$row[Sname]' >$row[Sname]</option> ";
}
并在接收页面中添加
list($SID, $Sname) = explode("|", $_POST['Sname']);
它的工作原理,但对于其他页面,我想要相同的值,我试图把相同的爆炸()但它不起作用..给我一个错误说未定义的索引:Sname +未定义的偏移量: 1 ..我的问题是我怎样才能传递相同的价值Sname&amp;也适用于其他页面?

您可以通过会话执行此操作,在要传递的会话中存储值
首先你需要通过
开始会话<?php //must not any spave before php tag and must be on very first line
session_start();
比您想要的商店值
$_SESSION['views'] = 5;
你可以在你想要的页面上访问
echo "Views=". $_SESSION['views'];
