php - 保存条目到数据库

Question

我已经成功地建立了一个数据库连接，用于存储一些条目的简单表单。它确实显示条目已与表单一起提交，但是它不显示已提交的信息。相反，它在我在表中创建的条目列中显示 NULL。我需要它来显示提交的内容。这是我的代码:

if($_SERVER['REQUEST_METHOD'] == 'POST'
    && $_POST['submit']=='Save Entry'
    && !empty($_POST['title'])
    && !empty($_POST['entry'])) 
{
    // Include database credentials and connect to the database
    include_once 'db.inc.php';
    $db = new PDO(DB_INFO, DB_USER, DB_PASS);

    // Save the entry into the database
    $sql = "INSERT INTO entries (title, entry) VALUES (?, ?)";
    $stmt = $db->prepare($sql);
    $stmt->execute(array($title, $entry));
    $stmt->closeCusor();

    // Get the ID of the entry we just saved
    $id_obj = $db->query("SELECT LAST_INSERT_ID");
    $id = $id_obj->fetch();
    $id_obj->closeCursor();

    // Continue processing information
}

// If both conditions aren't met, sends the user back to the main page
else {
    header('Location: ../amin.php');
    exit;
}

您还没有在任何地方为 $title 和 $entry 设置值。您在尝试调用 call closeCursor() 时也有错字。
