Question

我的第一个文件是signup.php，里面有表格。我需要将表单值传递给第4页，即createAccount.php。

在signup.php之后，我有一个与creaditCardInfo.php（第三个文件）文件链接的userAgreement.php（第二个文件）文件。最后，我有createAccount.php文件。
我需要帮助。我知道我可以在$ _session中存储表单值，但它不起作用。
你能帮我弄清楚错误在哪里吗？

下面是我的4个文件。

<?php
include 'preCode.php';
include 'header.php';
echo '<body><div class="standardLayout">';
echo '<h2>Account Information</h2>';
?>
<form method="post" action="userAgreement.php">
<table>
<tr><td>Email:</td><td><input type="text" name="email"></td></tr>
<tr><td>First Name:</td><td><input type="text" name="fName"></td</tr>                   
<tr><td><input type="submit" value="Create Account"></td></tr>
  </table>
   </form>
 <?php
 echo'</div>';
 include 'footer.html';
  ?>

userAgreement.php（第2页）

   <?php
   include 'preCode.php';
   include 'header.php';
   echo '<body><div class="standardLayout">';
   include 'systemMenu.php';
     $_SESSION['email'] = secure_input($_POST['email']);
     $_SESSION['fName'] = secure_input($_POST['fName']);
     ?>

creditCardInfo.php（第3页）

     <?php
        include 'preCode.php';
        include 'header.php';
         echo '<body><div class="standardLayout">';
         include 'systemMenu.php';
         $_SESSION['email'] = secure_input($_POST['email']);
         $_SESSION['fName'] = secure_input($_POST['fName']);
        ?>

createAccount.php（第4页）

    <?php
     include 'preCode.php';
     include 'header.php';
     echo '<div class="standardLayout">';
     include 'systemMenu.php';
     $_SESSION['fName'] = secure_input($_POST['fName']);
     $_SESSION['email'] = secure_input($_POST['email']);
     $email = $_SESSION['email'];
     echo $email;
     $_SESSION['fromLogin'] = false;
     $user = new user();
     $user->fName = secure_input($_POST['fName']);
     $user->email = secure_input($_POST['email']);
     $query = "INSERT INTO Users (fName, email)VALUES ('" . $user->fName . "', '" . $user->email . "');
     echo '<h2>User Information</h2>
    <div class="left">
   <form method="post" action="editUser.php">
    // I want to display session values here in this form. But its not printing anything except the field names(Name and email).
  <i>Name:</i>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; '$user->fName . '<br>
  <i>Address:</i>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'$user->address .'<br>
   <input type="submit" value="Edit Information"></form>';

Answer 1

最后一页（createAccount.php）似乎是问题所在。您可以根据表单提交为会话变量分配值，但是根据代码判断，没有表单提交到该页面。不是永久地分配这些变量，而是简单地使用存储的会话变量，而不是使用有效的空值重新分配。事实上，第3页也是如此 - 似乎没有一个表单发布到第3页，所以再一次用空值覆盖会话变量。当然，在包含的文件中可能有一个表单，但如果是这样的话，为什么还有另外一对字段＆＃39; email＆＃39;和＆＃39; fName＆＃39; ??

creditCardInfo.php(page 3)
--------------------------
 <?php
    include 'preCode.php';
    include 'header.php';
    echo '<body><div class="standardLayout">';
    include 'systemMenu.php';
 ?>

 createAccount.php(page 4)
 -------------------------
<?php
     include 'preCode.php';
     include 'header.php';
     echo '<div class="standardLayout">';
     include 'systemMenu.php';

     $email = $_SESSION['email'];
     $_SESSION['fromLogin'] = false;

     echo $email;

     $user = new user();
     $user->fName = $_SESSION['fName'];
     $user->email = $_SESSION['email'];
     $query = "INSERT INTO Users (fName, email)VALUES ('" . $user->fName . "', '" . $user->email . "');

     echo '
        <h2>User Information</h2>
        <div class="left">
        <form method="post" action="editUser.php">
            <i>Name:</i>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; '.$user->fName . '<br>
            <i>Address:</i>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'.$user->address .'<br>
            <input type="submit" value="Edit Information">
        </form>';
?>
