Question

当我尝试将表单a提交到表单b并使用javascript window.open或者表单标记本身上的action =“”属性将其加载到新页面时，所有内容都会正确触发但在新页面上加载SESSION变量未传递。但是，如果我拿走window.open方法，提交表单并在我的浏览器中手动加载新页面，SESSION变量确实在新页面的输入字段中以表格b ...

正确显示

我想知道它是否与“return false”有关。我已经在表单上运行的onsubmit函数的一部分或者如果在表单提交和新页面加载时，它没有在SESSION存储它们之前设置SESSION值并将新页面加载到窗口中...它必须是那两个罪魁祸首。如果我不进行页面重定向，IT工作正常，所以我认为在提交后加载新页面时实际上并不存储SESSION变量...如何正确并成功地将SESSION存储在新页面加载中以便加载在表格b的新页面中正确显示？

索引文件（表格A）

<?php
session_start();
if(isset($_POST['submit'])) {
    $_SESSION['cable_no'] = $_POST['cable_no'];
    $_SESSION['co_name'] = $_POST['co_name'];
    $_SESSION['prepping_team'] = $_POST['prepping_team'];
    $_SESSION['section_no'] = $_POST['section_no'];
    $_SESSION['tech_name_a'] = $_POST['tech_name_a'];
}
?>
