How to Handle Video Uploads with Folder Organization and Database Entry in PHP and MySQL?

How to Upload Video Files via PHP and Save Them in Appropriate Folders with Database Entry

Introduction

To manage video uploads on your website effectively, you need to implement a system that allows users to upload videos, stores them in organized folders, and tracks their metadata in a database. This guide will provide a comprehensive solution for achieving this using PHP and MySQL.

HTML Form

Create an HTML form that allows users to select and upload video files:

<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 Handler

Now, let's write the PHP script to handle file uploads and database entry:

<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>

This code will automatically organize video files into subfolders based on the selected course and add a database entry with the file details.
