Question

我已在html中创建了一个付款表单。表单中的值会自动添加会话。当用户登录时，使用用户信息添加值。我的html如下：

＆＃13;

<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>

＆＃13;

在登录页面中，我已按如下方式存储会话：

＆＃13;

<?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>";
}
}

用户电子邮件在表单中正确输入，但手机号码和其他详细信息未添加到表单中。我尝试将它们串起来作为上面的变量，但它没有显示。我想我需要从数据库中获取详细信息。谁能告诉我怎么做？

Answer 1

我做了很多研究，最后自己回答了问题。

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循环将它们放在变量中。更新的代码如下：

＆＃13;

<div  class="sing"><?php
session_start();

if (isset($_SESSION['email']) && $_SESSION['email'] == true) {
  echo " &nbsp Welcome  " . $_SESSION['email'] ;
echo "<div style='float: right;'><a href='logout.php'>Logout</a>&nbsp</div>";
} else {

}


?>
</div>
<!DOCTYPE html>
<html>
<head>
</head>
<body>
	<div>
		<h2>Payment Gateway Testing Sample</h2>
		<h3>Fill the form and submit it for starting the transaction...</h3>
	</div>

<div>



  <?php

  include("config.php");


$user_email=$_SESSION['email'];
  $check_user="select * from users WHERE user_email='$user_email'";

  $run=mysqli_query($dbcon,$check_user);

while($row = $run->fetch_assoc())
{

 $user_name=$row['user_name'];
 $user_mobile=$row['user_mobile'];

}
  //here session is used and value of $user_email store in $_SESSION.




  ?>


<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="" /></td></tr>



	<tr><td>Name</td><td><input type="text" name="firstname" value="<?php echo $user_name; ?>" /></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="mobile" value="<?php echo $user_mobile; ?>" /></td></tr>
	<tr><td>productinfo</td><td><input type="text" name="productinfo" value="" /></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>
