我面临的困境是我创建的用于存储varibale（用户名）的会话未显示。我想在用户注册<ul class="slider">
<li>
<img src="http://placehold.it/300/0074D9/FFFFFF?text=One"><span class="tip">Tip1</span></img>
</li>
<li>
<img src="http://placehold.it/300/39CCCC/000000?text=Two"><span class="tip">Tip2</span></img>
</li>
<li>
<img src="http://placehold.it/300/2ECC40/000000?text=Three"><span class="tip">Tip3 </span></img>
</li>
<li>
<img src="http://placehold.it/300/FF851B/000000?text=Four"><span class="tip">Tip4</span></img>
</li>
<li>
<img src="http://placehold.it/300/85144b/FFFFFF?text=Five"><span class="tip">Tip5</span></img>
</li>
</ul>后在maindash.html中显示用户名。

用户登录后，它不会显示用户名。我想创建它，因为用户名应该从数据库文件中获取并显示在<?php
session_start();
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "index";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$email = $_POST['email'];
$password = $_POST['password'];
$sql = "INSERT INTO form ( email, password )
VALUES ( '$email', '$password')";
if ($conn->query($sql) === TRUE) {
header('Location: sign-up.html');
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
if($count == 1)
{
$_SESSION['logged'] = true;
$_SESSION['username'] = $myusername;
echo "Login worked";
exit();
}
else
{
$_SESSION['logged']=false;
echo "Login failed";
exit();
}
?>
<li class='active' style='float:right;'>
<?php
if($_SESSION['logged'] == true)
{
echo $_SESSION["name"];
echo '<a href="logout.php"><span>Logout</span></a></li>';
}
elseif($_SESSION['logged'] == false)
{
echo '<a href="sign-up.html"><span>Login/Register</span></a></li>';
}
//Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM form where email = $email and password = $password";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo " Name: " . $row["name"]. ".<br>";
}
} else {
echo "0 results";
}
$conn->close();
?>
中。但它只显示我在代码中写的Hello。
答案 0 :(得分：0)
将您的maindash.html页面重命名为.php分机。在页面顶部（maindash.php ie）确保你输入
<?php
session_start();
?>
