【问题描述】:
我创建了一个 html 格式的付款表单。表单中的值是使用会话自动添加的。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 $_SESSION['productinfo']; ?>" /></td></tr>
<tr><td><input type="hidden" name="surl" value="success.php" size="64" /></td></tr>
<tr><td><input type="hidden" name="furl" value="fail.php" size="64" /></td></tr>
<tr><td><input type="submit" /></td><td><input type="reset" /></td></tr>
</form>
</table>
在登录页面中,我将会话存储如下:
<?php
session_start();
include("config.php");
if(isset($_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>";
}
}
?>

用户邮箱在表单中输入正确,但手机号码等详细信息未添加到表单中。我尝试将它们作为上面的变量串起来,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?
【问题讨论】:
-
您检查过
$result包含的内容吗? -
我也尝试过结果,但它显示未定义的索引
-
您的代码容易受到 sql 注入的攻击。请了解如何在查询中使用准备好的语句。 websitebeaver.com/…
-
你试过
echo $result[0]['access']吗? -
使用
print_r($result);正下方的$result=mysqli_fetch_array($run);来获取存储的数据。用户print_r(error_get_last());就在它下面,看看有没有连接错误什么的。
