Welcome 歡迎來到「睡醒來聽 PHP 與 MySQL」系列！

DAY29 今天要學甚麼?今天實作預約管理者畫面(2)-管理者!!

🔶章節:
🔹[開頭]
🔹[管理者 VS 使用者]
🔹[實作的資料表內容]
🔹[目前的文件]
🔹[網站管理畫面]
🔹[管理新增預約]
🔹[完成標示]
🔹[網站實作呈現]
🔹[總結]

如果影片中不清楚，需要補充的地方我會再添加到這邊~
👆教學中的[練習]程式碼一併附上，影片中會有每組的講解、說明更清楚👆

管理新增預約

createWeb.php

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>建立訂單</title>
</head>
<body>
<?php
session_start();
include 'db_connect.php';


if (isset($_SESSION['user_id']) && $_SESSION['user_id'] == 1) {
   
    echo '<h2>建立訂單</h2>';
    echo '<a href="adminWeb.php?action=show_all">顯示所有訂單</a> | ';
    echo '<a href="adminWeb.php?action=show_today">顯示今天的預約</a> | ';
    echo '<a href="create_order.php">建立訂單</a><br><br>';

    
    echo '<h3>填寫預約資訊</h3>';
    echo '<form action="create_order.php" method="post">';
    echo '預約類型: ';
    echo '<select name="type">';
    echo '<option value="VR體驗">VR體驗</option>';
    echo '<option value="諮商師諮詢">諮商師諮詢</option>';
    echo '</select><br>';
    echo '預約日期：<input type="date" name="date" required><br>';
    echo '預約時間：<input type="time" name="time" required><br>';

    echo '</form>';
} else {
    echo "只有管理者可以訪問此頁面";
}
$conn->close();
?>
</body>
</html>

儲存新建立的訂單到資料庫中

create_order.php

<?php
session_start();
include 'db_connect.php'; 
include 'user_info.php';

    if ($_SERVER["REQUEST_METHOD"] == "POST") {
        
        if (isset($_SESSION['user_id'])) {
            $user_id = $_SESSION['user_id'];
            $userInfo = getUserInfo($user_id, $conn);  


            $account = $userInfo['account'];
        
            $type = $_POST['type'];
            $date = $_POST['date'];
            $time = $_POST['time'];
            $email = $_POST['email'];
            $name = $_POST['name'];
            $phone = $_POST['phone'];
            $created_at = date('Y-m-d H:i:s');

            //資料存入 資料庫   'appointments' 資料表
            $sql = "INSERT INTO appointments (account, type, date, time, email, name, phone, status) 
                    VALUES ('$account', '$type', '$date', '$time', '$email', '$name', '$phone', '未完成')";

            if ($conn->query($sql) === TRUE) {
                echo "訂單建立成功！";
                echo "<br><a href='adminWeb.php'>回到管理者畫面</a>";
            } else {
                echo "錯誤：" . $sql . "<br>" . $conn->error;
            }
        }
    }
$conn->close();
?>

更新訂單完成狀態

mark_completed.php

<?php
include 'db_connect.php';

if ($_SERVER['REQUEST_METHOD'] === 'POST' && isset($_POST['order_id'])) {
    $orderId = $_POST['order_id'];

    // 更新訂單狀態為已完成
    $updateQuery = "UPDATE appointments SET status = '已完成' WHERE order_id = $orderId";
    mysqli_query($conn, $updateQuery);

    // 重新導向回管理者頁面
    header("Location: adminWeb.php?action=show_today");
    exit;
}
?>

從網頁開發到資料庫管理，從登入驗證到訂單管理。透過這些學習，您已經建立了一個完整的預約系統，能夠讓使用者進行預約、管理者查看訂單、以及進行狀態的更改。這個過程不僅加深了對網頁開發和資料庫操作的理解，也培養了解決問題和設計系統的能力。
