如何通过 PHP 上传视频文件并通过数据库条目将它们保存在适当的文件夹中
简介
为了有效管理网站上的视频上传,您需要实现一个系统,允许用户上传视频,将它们存储在有组织的文件夹中,并在数据库中跟踪其元数据。本指南将提供使用 PHP 和 MySQL 实现此目的的全面解决方案。
HTML 表单
创建一个允许用户选择和上传视频文件的 HTML 表单:
<code class="html"><form method="post" enctype="multipart/form-data"> <div class="form-group"> <label for="file">Select Video File:</label> <input type="file" name="file" id="file" accept="video/*" required> </div> <div class="form-group"> <label for="course">Course:</label> <select name="course" required> <option value="select">Select Course</option> <option value="java">Java</option> <option value="python">Python</option> <option value="vb">Visual Basic</option> <option value="c">C/C++</option> <option value="ruby">Ruby</option> </select> </div> <input type="submit" name="submit" value="Upload"> </form></code>
PHP 处理程序
现在,让我们编写 PHP 脚本来处理文件上传和数据库输入:
<code class="php"><?php // Set destination folder and allowed file extensions define('DESTINATION_FOLDER', 'videos/'); $allowedExtensions = ['mp4', 'webm', 'avi', 'mov']; // Database settings $host = 'localhost'; $database = 'video_database'; $username = 'user'; $password = 'password'; // Connect to database $conn = new mysqli($host, $username, $password, $database); if ($conn->connect_error) { die("Connection failed: " . $conn->connect_error); } // Process file upload if (isset($_POST['submit'])) { // Get file details and validate extension $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileExtension = pathinfo($fileName, PATHINFO_EXTENSION); if (!in_array($fileExtension, $allowedExtensions)) { echo "Invalid file format. Please upload a valid video file."; exit; } // Check if there are any upload errors if ($_FILES['file']['error'] > 0) { echo "Error uploading file."; exit; } // Move file to destination folder $fileDestination = DESTINATION_FOLDER . $fileName; if (move_uploaded_file($_FILES['file']['tmp_name'], $fileDestination)) { // Insert file details into database $course = $_POST['course']; $uploadDate = date("Y-m-d H:i:s"); $sql = "INSERT INTO video_uploads (video_name, course, upload_date) VALUES ('$fileName', '$course', '$uploadDate')"; if ($conn->query($sql)) { echo "File uploaded successfully. Database entry added."; } else { echo "Error adding database entry."; } } else { echo "Error moving file to destination."; } } $conn->close();</code>
此代码将自动根据所选课程将视频文件组织到子文件夹中,并添加包含文件详细信息的数据库条目。
