无法在表单提交中存储会话变量

Question

当我尝试将表单a提交给表单b并使用javascript window.open或者表单标记本身的action =“”属性将其加载到新页面时，关闭正确，但在新的页面加载SESSION变量不传递。但是，如果我拿走了window.open方法，提交表单并手动加载我的浏览器中的新页面，SESSION变量在窗体b的新页面上的输入字段中确实出现...

I想知道这与“回报错误”有什么关系？部分onsubmit函数我运行在form上，或者如果在表单提交和新的页面加载时，它不会在SESSION存储它们并将新页面加载到窗口之前设置SESSION值......它必须是那两个匪徒。如果我不做一个页面重定向，它的工作原理，所以我相信它实际上不是在提交后加载新页面时存储SESSION变量......我如何正确和成功地将SESSION存储在新页面加载中，以便加载正确地在form b上的新页面中？

索引文件（FORM 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']; 
} 
?>

function uploaddata() { 

//Read all of the data from the page

     upload_prepform(); 
    }else{ 
     alert("Please verify that you have checked the known check boxes.") 
    }

function upload_prepform() { 
    $.ajax({ 
      type: 'POST', 
      url: './php/upload_prepform.php',

      async: false, 
      dataType: 'text', 
      success: function() { 
       alert("Thank you. Your Prep form has been submitted."); 
      }, 

      error: function(jqXHR, textStatus, errorThrown) { 
        alert("Error... " + textStatus + "\n" + errorThrown); 
      }, 
      complete: function() { 
       window.location.replace("http://dev1.rs.idmyasset.com/gp21-dev/prep_b/"); 
       alert("Redirecting..."); 
      } 
     }); 
    };
