1.php? 2.php
session_start(); session_start();
.......... ..........
$_SESSION['a'] =$a; echo $_SESSION['a'];
$_SESSION['b'] =$b; echo $_SESSION['b'];
header("location: 2.php");
after jump to 2.php ,there is an warning: undefined index a ,b
if i change 1.php to
session_start();
..........
$_SESSION['a'] =$a;
$_SESSION['b'] =$b;
<a href='2.php' >go on </a>
it works well!
Best regards and thanks in advance,
bob
