How to Upload Video Files to a Folder, Create a Database Entry, and Perform Validation with PHP?

使用PHP 上傳視訊檔案並將其保存在適當的資料夾中並建立資料庫條目

此PHP 腳本允許使用者將視訊檔案上傳到指定資料夾並建立對應的資料庫條目資料庫項目:

<code class="php"><?php

// Upload settings
define('DESTINATION_FOLDER', '/uploads/'); // Folder to save uploaded videos
define('MAX_FILE_SIZE', 10485760); // Maximum file size allowed in bytes (10MB)
define('ALLOWED_EXTENSIONS', ['avi', 'mov', 'mp4']); // Allowed file extensions

// Database settings
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASSWORD', '');
define('DB_NAME', 'my_database');

// Initialize variables
$errors = [];
$message = '';
$uploadSuccess = false;

// Process form submission
if (isset($_POST['submit'])) {

    // Fetch form data
    $filename = $_FILES['filename']['name'];
    $tmp_filename = $_FILES['filename']['tmp_name'];
    $file_ext = strtolower(pathinfo($filename, PATHINFO_EXTENSION));
    $filesize = $_FILES['filename']['size'];

    // Validate file
    if (!$tmp_filename) {
        $errors[] = 'Error: No file selected.';
    } elseif (!in_array($file_ext, ALLOWED_EXTENSIONS)) {
        $errors[] = 'Error: File type not allowed.';
    } elseif ($filesize > MAX_FILE_SIZE) {
        $errors[] = 'Error: File size exceeds limit.';
    }

    // Upload file if no errors
    if (empty($errors)) {
        $newFilename = uniqid() . '.' . $file_ext;
        $uploadPath = DESTINATION_FOLDER . $newFilename;

        // Move uploaded file to the specified folder
        if (move_uploaded_file($tmp_filename, $uploadPath)) {
            $uploadSuccess = true;
            $message = 'File uploaded successfully.';
        } else {
            $errors[] = 'Error: Unable to move uploaded file.';
        }
    }

    // Create database entry if upload was successful
    if ($uploadSuccess) {
        try {
            // Establish database connection
            $conn = new PDO('mysql:host=' . DB_HOST . ';dbname=' . DB_NAME, DB_USER, DB_PASSWORD);
            $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

            // Prepare SQL query
            $stmt = $conn->prepare("INSERT INTO uploads (`name`, `path`) VALUES (?, ?)");
            $stmt->execute([$filename, $uploadPath]);
        } catch (PDOException $e) {
            $errors[] = 'Error: Database connection failed: ' . $e->getMessage();
        }
    }
}

?>

<!DOCTYPE html>
<html>
<head>
    <title>Upload Video Files</title>
</head>
<body>

    <h1>Upload Video Files</h1>

    <form method="post" enctype="multipart/form-data">
        <label for="filename">Filename:</label>
        <input type="file" name="filename">

        <input type="submit" name="submit" value="Upload">
    </form>

    <?php if (!empty($message)): ?>
        <div><?php echo $message; ?></div>
    <?php endif; ?>

    <?php if (!empty($errors)): ?>
        <ul>
            <?php foreach ($errors as $error): ?>
                <li><?php echo $error; ?></li>
            <?php endforeach; ?>
        </ul>
    <?php endif; ?>

</body>
</html></code>

提交後,此腳本執行以下任務:

  • 驗證上傳的檔案類型、大小和副檔名。
  • 移動上傳檔案到指定資料夾。
  • 建立資料庫連線並在上傳表中插入包含影片檔案名稱和路徑的條目。
