问题描述
以下是代码的最新更新，但它仍然不会将变量值显示为iframe网址。变量调用db行数据。
iframe不会打开变量中提到的URL。请仔细查看代码底部。
Here is latest update of the code but still it shows not the variable value as the iframe URL. Variable calls db row data.
The iframe is not opening to the URL mentioned in the variable. Look right at the bottom of the code.
<html>
<head>
<title>
<?php
$user Home Page
?>
</title>
</head>
<body>
<body background=".png">
<?php
session_start();
require "conn.php";
/*Check if user is logged-in or not by checking if session is set or not.
If user is not logged-in then redirect to login page. Else, show user's account homepage.*/
if(!isset($_SESSION["user"]))
{
header("location:login.php");
}
else
{
$user = $_SESSION["user"];
$sql = "SELECT * FROM $user WHERE Username = '".$user."'";
$result = $conn->query($sql);
while($row = $result->fetch_assoc())
{
$db_id = $row["Id"];
$db_username = $row["Username"];
$db_forename = $row["Forename"];
$db_surname = $row["Surname"];
$db_email = $row["Email"];
$db_bio = $row["Bio"];
$db_latest_view = $row["Latest_View"];
//Welcome user by name.
echo "<center>Welcome <h2>$db_forename $db_surname!</center>"?></h2>|
<?php
//Display log-out link.
echo "<p align='right'><a href='logout.php'>$user Log Out</a>";?>|</p><br>
<?php
//Display User Bio.
echo "<br>Bio:<br>";
echo "$db_bio";?><br>
<br>
<?php
//Display User's Latest View.
echo "<br>Latest View:<br>";
echo "$db_latest_view";?><br>
<br>
<?php
//Display User's Latest Viewed Url in iFrame.?>
<iframe src="<?php $db_latest_view;?>"></iframe>
<?php
