我已经用 html 创建了一个付款表单。表单中的值是使用 session 自动添加的。当用户登录时，使用用户信息添加值。我的 html 如下:
<table>
<form name="postForm" action="form_process.php" method="POST" >
<tr><td><input type="hidden" name="txnid" value="<?php echo $txnid=time().rand(1000,99999); ?>" /></td></tr>
<tr><td>amount</td><td><input type="text" name="amount" value="<?php echo $_SESSION['amount']; ?>" /></td></tr>
<tr><td>firstname</td><td><input type="text" name="firstname" value="<?php echo $_SESSION['firstname']; ?>" /></td></tr>
<tr><td>email</td><td><input type="text" name="email" value="<?php echo $_SESSION['email']; ?>" /></td></tr>
<tr><td>phone</td><td><input type="text" name="phone" value="<?php echo $_SESSION['phone']; ?>" /></td></tr>
<tr><td>productinfo</td><td><input type="text" name="productinfo" value="<?php echo $_SESSION['productinfo']; ?>" /></td></tr>
<tr><td><input type="hidden" name="surl" value="success.php" size="64" /></td></tr>
<tr><td><input type="hidden" name="furl" value="fail.php" size="64" /></td></tr>
<tr><td><input type="submit" /></td><td><input type="reset" /></td></tr>
</form>
</table>在登录页面中，我将 session 存储如下:
<?php
session_start();
include("config.php");
if(isset($_POST['login']))
{
$user_email=$_POST['email'];
$user_pass=$_POST['pass'];
$check_user="select * from users WHERE user_email='$user_email'AND user_pass='$user_pass'";
$run=mysqli_query($dbcon,$check_user);
if(mysqli_num_rows($run)>0)
{
$result=mysqli_fetch_array($run);
$_SESSION['email']=$user_email;
$_SESSION['access']=$result['access'];
//here session is used and value of $user_email store in $_SESSION.
echo "<script>window.open('index.php','_self')</script>";
}
else
{
echo "<script>alert('Email or password is incorrect!')</script>";
}
}
?>

</html>用户邮箱在表单中输入正确，但手机号码和其他详细信息未添加到表单中。我试过像上面那样将它们串成变量，但它没有显示。我想我需要从数据库中获取详细信息。谁能告诉我该怎么做？
最佳答案
我做了很多研究，终于自己找到了答案。
我使用 $_SESSION 和 select 查询从数据库中获取当前用户的信息。并使用 while 循环将它们放入变量中。 更新后的代码如下:
<div class="sing"><?php
session_start();
if (isset($_SESSION['email']) && $_SESSION['email'] == true) {
echo "   Welcome " . $_SESSION['email'] ;
echo "<div style='float: right;'><a href='logout.php'>Logout</a> </div>";
} else {
}
?>
</div>
