如何在 PHP 中上传视频文件并通过数据库集成对其进行分类？

如何通过 PHP 上传视频文件并将其保存在带有数据库条目的适当文件夹中

问题：

用户需要能够将视频文件上传到网站，并将其存储在指定的文件夹中，并具有相应的数据库条目以供用户识别。

解决方案：

HTML 表单

定义用户选择要上传的视频文件的 HTML 表单。确保表单包含用于文件选择和提交的适当属性。

<code class="html"><form method="post" enctype="multipart/form-data">
    <input type="file" accept="video/*" id="fileSelect" name="filename">
    <select name="course">
        <option value="select" selected>Select</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>
    <input type="submit" value="Upload" name="submit">
</form></code>

PHP 处理程序

使用 PHP 处理上传的视频文件：

<code class="php">// Define destination folder based on selected course
$folder  = isset($_POST["course"]);

// Destination folder path
$destination_folder = '/' . $folder;

// Maximum file size (in bytes)
$max_file_size = 0;

// Success URL for redirection after upload
$success_url = 'learn.learnbrix.com';

// Upload success log database connection details (optional)
define('DB_HOST',''); // host, usually localhost
define('DB_DATABASE',''); // database name
define('DB_USERNAME',''); // username
define('DB_PASSWORD',''); // password

// Check for upload errors
$error_code = $_FILES['filename']['error'];
if ($error_code !== UPLOAD_ERR_OK) {
    // Handle upload errors as needed
}

// Process the uploaded file
$filename = $_FILES['filename']['name'];
$tmp_filename = $_FILES['filename']['tmp_name'];
$file_ext = strtolower(pathinfo($filename, PATHINFO_EXTENSION));
$filesize = filesize($tmp_filename);

// Check file size and type
if ($filesize > $max_file_size) {
    // Handle file size error
}
if (!in_array($file_ext, array('mp4', 'avi', 'mov'))) {
    // Handle file type error
}

// Save the file in the destination folder
$dest_filename = md5(uniqid(rand(), true)) . '.' . $file_ext;
move_uploaded_file($tmp_filename, $destination_folder . '/' . $dest_filename);

// Log the upload (optional)
if (DO_LOG) {
    // Connect to the database and execute the query to log the upload
}

// Redirect to the success URL
header('Location: ' . $success_url);</code>

其他功能

要添加接受用户姓名和电子邮件地址的功能，请相应修改 HTML 表单和 PHP 处理程序：

HTML 表单

<code class="html"><form method="post" enctype="multipart/form-data">
    <label for="name">Name:</label>
    <input type="text" name="name">

    <label for="email">Email:</label>
    <input type="email" name="email">

    <input type="file" accept="video/*" id="fileSelect" name="filename">
    <select name="course">
        <option value="select" selected>Select</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>
    <input type="submit" value="Upload" name="submit">
</form></code>

PHP 处理程序

<code class="php">// Get the user's name and email from the form
$name = $_POST['name'];
$email = $_POST['email'];

// Use $name and $email to create a database entry or perform any other necessary action</code>
