Question

我已经制作了一个简单的注册表格。当我注册时，我必须输入电子邮件，密码和全名。但是一旦我注册，它就成功插入到数据库中。但是我想让它在顶级heeader上显示用户的名字。首先，下面的代码如下：

registerForm.php：

<form id="myForm" action="actions/register.php" method="POST">  
            <p> Email Address : </p>
            <p> <input name="email" required="required" type="text" placeholder="eg. john.wick@yahoo.com"/> </p>
            <p> Password : </p>
            <p> <input name="password" required="required" type="password" placeholder="Your password"/> </p>
            <p> Full Name : </p>
            <p> <input name="name" required="required" type="text" placeholder="Your full name"/> </p> 
    <p class="centre"> <input type="submit" value="REGISTER"> </p>
</form>

register.php：

<?php 
    session_start();
    include "../config/dbconnect.php";

        $name = ucwords(htmlspecialchars($_POST['name']));
        $emailAddress = htmlspecialchars($_POST['email']);
        $registerPassword = $_POST['password'];

        $name = $mysqli->real_escape_string($name);
        $emailAddress = $mysqli->real_escape_string($emailAddress);
        $registerPassword = $mysqli->real_escape_string($registerPassword);


        $salt = sha1(md5($registerPassword));
        $hashedPW = md5($registerPassword.$salt);

        $check = "SELECT * FROM memberTable where email = '$emailAddress'";
        $checkTitle = mysqli_query($mysqli,$check) or die(mysqli_error($mysqli));

        if (mysqli_num_rows($checkTitle) > 0) {
           header("location: ../header.php");
        } else {
            $insertSQL = "INSERT INTO memberTable (email, password, name) VALUES ('$emailAddress', '$hashedPW', '$name')";
            $queryResult = mysqli_query($mysqli,$insertSQL) or die(mysqli_error($mysqli));

            if($queryResult) {
                $user_info = array(
                    'name' => $name,
                );

                $_SESSION['login'] = true;
                $_SESSION['user_info'] = $user_info;
            }

            header("location: ../index.php");
            exit;
        }

    mysqli_close($mysqli);
?>

如果未成功注册，则会显示登录表单。注册成功，它将直接到header.php。要知道我已将我的全名，电子邮件和密码插入数据库。我希望我的全名显示在标题上。如下所示：

<div class="topRight">
        <?php
            ini_set('display_errors',1); 
            include "config/dbconnect.php";

            if(isset($_SESSION['login']) && !empty($_SESSION['login'])) {            
                $name = $_SESSION['user_info']['name'];

                echo '<p> <a href="profileUser"> Profile : $name </a>';
                echo '<p> <a href="actions/logout.php"> Logout </a> </p>';

                } else {

                echo    '<form action="actions/login.php" method="POST">
                            <input type="text" name="email" placeholder="Email">
                            <input type="password" name="password" placeholder="Password">
                            <input type="submit" value="LOGIN">
                        </form>';

                echo    '<p> <a href="registerForm.php" class="underline"> Not a member? Register here! </a> </p>';
            }
        ?>
    </div>

问题是Profile : $name无效。它没有显示名称，只是在网页上显示$name。有什么想法吗？

Answer 1

单引号内的变量不会被解析。 PHP Documentation

Answer 2

试试这个。，

echo '<p> <a href="profileUser"> Profile :'.$name.'</a>';

你应该保持正确关闭报价，

注册成功但不是会话调用用户名
