Question

我正在尝试为表单的每个字段创建一个会话，以便我可以在下一页的附加信息表单中重新调用它。

<?php 
 session_start(); // starting the session

 if (isset($_POST['Submit'])) { 

     $_SESSION['breakdowndate'] = $_POST['breakdowndate'];
     $_SESSION['policyinception'] = $_POST['policyinception'];
     $_SESSION['customername'] = $_GET['customername'];
     $_SESSION['customersurname'] = $_GET['customersurname'];
     $_SESSION['covertype'] = $_POST['covertype'];
     $_SESSION['vehiclemake'] = $_POST['vehiclemake'];
     $_SESSION['vehiclemodel'] = $_POST['vehiclemodel'];
     $_SESSION['vehiclereg'] = $_POST['vehiclereg'];
     $_SESSION['vehicleage'] = $_POST['vehicleage'];
     $_SESSION['excess'] = $_POST['excess'];
     $_SESSION['mileage'] = $_POST['mileage'];
     $_SESSION['paid'] = $_POST['paid'];
     $_SESSION['HSRS'] = $_POST['HSRS'];
     $_SESSION['fault'] = $_POST['fault'];
     $_SESSION['garage'] = $_POST['garage'];
     $_SESSION['telephone'] = $_POST['telephone'];

    } 

?>

使用一些代码并经过一些修改后，我上面的代码试图存储已在表单中提交的数据..

如何改进此代码以使其正常工作？

Answer 1

如果无效，请尝试调试。

如果它正在保存POST，那么就没有什么可做的了。

将session.cookie.secure设为true。您可能需要设置session.cookie_lifetime。

就安全性而言，考虑一下你是否有值得保护的东西。如果有人获得访问者的会话cookie，这有关系吗？如果没有，请忘掉它。

session_set_cookie_params(0, '/', '', true, false);
session_start(); 

error_reporting(E_ALL);  // debug

if (isset($_POST['Submit'])) { 
  $_SESSION['breakdowndate'] = $_POST['breakdowndate'];
  $_SESSION['policyinception'] = $_POST['policyinception'];
  $_SESSION['customername'] = $_GET['customername'];
  $_SESSION['customersurname'] = $_GET['customersurname'];
  $_SESSION['covertype'] = $_POST['covertype'];
  $_SESSION['vehiclemake'] = $_POST['vehiclemake'];
  $_SESSION['vehiclemodel'] = $_POST['vehiclemodel'];
  $_SESSION['vehiclereg'] = $_POST['vehiclereg'];
  $_SESSION['vehicleage'] = $_POST['vehicleage'];
  $_SESSION['excess'] = $_POST['excess'];
  $_SESSION['mileage'] = $_POST['mileage'];
  $_SESSION['paid'] = $_POST['paid'];
  $_SESSION['HSRS'] = $_POST['HSRS'];
  $_SESSION['fault'] = $_POST['fault'];
  $_SESSION['garage'] = $_POST['garage'];
  $_SESSION['telephone'] = $_POST['telephone'];
} else {
  echo '<h3>Session Not Saved</h3>';
}

echo htmlentities(var_export($_REQUEST, true));  // debug
echo htmlentities(var_export($_SESSION, true));  // debug

<强> DEBUG

它应该工作 - 如果没有，测试和调试。

显示所有警告。

设置后检查$_SESSION。

检查请求。

$_REQUEST包含$_COOKIE，其中应包含SESSION Cookie。

我们需要重新生成id。试试这个。（抱歉英文不好）

<?php 
 session_start(); // starting the session

 if (isset($_POST['Submit'])) { 
     session_regenerate_id();
     $_SESSION['breakdowndate'] = $_POST['breakdowndate'];
     $_SESSION['policyinception'] = $_POST['policyinception'];
     $_SESSION['customername'] = $_GET['customername'];
     $_SESSION['customersurname'] = $_GET['customersurname'];
     $_SESSION['covertype'] = $_POST['covertype'];
     $_SESSION['vehiclemake'] = $_POST['vehiclemake'];
     $_SESSION['vehiclemodel'] = $_POST['vehiclemodel'];
     $_SESSION['vehiclereg'] = $_POST['vehiclereg'];
     $_SESSION['vehicleage'] = $_POST['vehicleage'];
     $_SESSION['excess'] = $_POST['excess'];
     $_SESSION['mileage'] = $_POST['mileage'];
     $_SESSION['paid'] = $_POST['paid'];
     $_SESSION['HSRS'] = $_POST['HSRS'];
     $_SESSION['fault'] = $_POST['fault'];
     $_SESSION['garage'] = $_POST['garage'];
     $_SESSION['telephone'] = $_POST['telephone'];
     session_write_close();
    } 

?>

将变量存储在数组中并循环，如下所示。您可以在下一页上使用session_start();并访问它们：

<?php 
         session_start(); // starting the session
        $sessionItems = array('breakdowndate','policyinception','customername'...'telephone');

         if (isset($_POST['Submit'])) { 
             foreach($sessionItems as $item) {
               $_SESSION[$item] = $_POST[$item];
             }
          } 

        ?>

会话不是由表单创建的？
