回声表格数据？

标签： php mysql

我正在尝试制作一份注册表格，基本上我有4页，第一页要求提供名字，姓氏和电子邮件，第二页要求出生日期和密码，第3页会询问一些统计/复选框项目第4页将提交表格。

目前我正在尝试将一个表单中的数据从一个页面回显到第2,3页，然后最终在第4页一起提交到mysql数据库中。

我收到更新数据库邮件时出错。

有人可以告诉我，如果我做得对，或者有更简单的方法吗？

感谢; 

<form class="" method="post" action="register_p2.php">
<div class="row first_name">
<input type="text" id="first_name" name="first_name" placeholder="First Name" />
</div>

<div class="row last_name">
<input type="text" id="last_name" name="last_name" placeholder="Last Name" />
</div>

<div class="row email">
<input type="email" id="email" name="email" placeholder="Email"  />
</div>

<input type="submit" value="Next >"  />

</form>

第2部分/第2页

使用session

尝试此操作 
    <? ob_start(); 
         session_start();?>
<?php
// GET ACCOUNT INFORMATION FROM FORM AND ASSIGN VARIABLES
$first_name = $_SESSION['first_name'];
$last_name = $_SESSION['last_name'];
$email = $_SESSION['email'];
?>
<?php
/*
// ECHO ACCOUNT INFORMATION
echo "<strong> Account Information: </strong>";
echo "<br />";
echo First Name: ";
echo "<br />";
echo $first_name;
echo "<br />";
echo "<br />";
echo "Last Name: ";
echo "<br />";
echo $last_name;
echo "<br />";
echo "<br />";
echo "Email: ";
echo "<br />";
echo $email;
echo "<br />";
echo "<br />";

如果您希望在多个页面上提供信息，则应将其存储在会话中。将$ _POST值存储到变量中时，只需执行类似的操作，并确保放置session_start（）;请拨打页面顶部。

<?php
session_start();
// other php code here

$_SESSION['first_name'] = $first_name;
$_SESSION['last_name'] = $last_name;
$_SESSION['email'] = $email;
?>

然后，您可以通过调用$ _SESSION ['first_name']或您想要访问的任何变量在任何页面上访问它们。一定要包含session_start（）;在每个需要使用这些变量的页面的顶部。
