Question

在test1.php上我有这个：

<?php
    echo "Session variables are about to be set.";
    // Set session variables
    $_SESSION["animal"] = "cat";
    echo "Session variables are set.";
    echo "Favorite animal is " . $_SESSION["animal"] . ".";
?>

<div ms_positioning="text2D" class="style7"><a href="javascript:winOpen();" test2.php="">Contact Information</a></div>

<script>
function winOpen() {

    window.open("/test2.php",null,"scrollbars=no,resizable=no,width=600,height=300,top=100,left=100");

}
</script>

在test2.php中，我有这个：

<?php
    // Echo session variables that were set on previous page
    echo "Favorite animal is " . $_SESSION["animal"] . ".";
?>

但是数据没有出现在test2.php上。它确实回应了test1.php。

有什么建议吗？

Answer 1

您需要致电

session_start();

在脚本开头处起作用。

Answer 2

加入fisrt代码 session_start();

试试这个

<?php 
session_start();
// Echo session variables that were set on previous page
echo "Favorite animal is " . $_SESSION["animal"] . ".";
?>

Answer 3

你的test1.php应该是这样的：

<?php
    session_start(); // In case you come back to test1.php
    echo "Session variables are about to be set.";
    // Set session variables
    $_SESSION["animal"] = "cat";
    echo "Session variables are set.";
    echo "Favorite animal is " . $_SESSION["animal"] . ".";
?>

<div ms_positioning="text2D" class="style7"><a href="javascript:winOpen();" test2.php="">Contact Information</a></div>

<script>
function winOpen() {

    window.open("/test2.php",null,"scrollbars=no,resizable=no,width=600,height=300,top=100,left=100");

}
</script>

test2.php应该是这样的：

<?php
    session_start();
    // Echo session variables that were set on previous page
    echo "Favorite animal is " . $_SESSION["animal"] . ".";
?>
