How to use Google Drive API to upload files in my Drive (PHP)?

I want to make a webpage in which there will be an file input box, and the files which user uploads, should be saved into my Google Drive.

How do I achieve it using PHP?

I don't want to use composer

I need refreance to a good article with some indications

I checked on Google but I found articles to write on other's Drive, but not my own. Also, I checked the Drive API documentation, but I think its too professional for me! Please tell me how to make a simple uploading PHP page.

Upload to Google Drive with the Google Drive API - without composer

What you need for integrating the feature with a Website:

  • Install the google-api-php-client
  • Install the Google_DriveService client
  • No matter how you upload files to Google Drive - you need some kind of credentials to show that you have access to the Drive in question (that is you need to authenticate as yourself).For this:
    • If not already done - set up (for free) the Google Cloud console.
    • Create a project.
    • Enable the Drive API.
    • Set up a consent screen.
    • Go to APIs & Services -> Credentials and +Create Credentials
    • There are several possibilities, in your case, it makes sense to create an OAuth client ID and chose Application type: Web Application
    • Specify the URL of your website with the form as Authorized JavaScript origins and Authorized redirect URIs
    • After creating the client - note down the client ID and client secret

Now, you can put together Google's sample for authentication with the OAuth2 client with the creation of the Google Drive service object and Uploading to Google Drive, then incorporate it into a PHP File Upload.

Patching those code snippets together could look like following:

form.html

<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
  Select image to upload:
  <input type="file" name="fileToUpload" id="fileToUpload">
  <input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>

upload.php

<?php
require_once 'google-api-php-client/src/Google_Client.php';
require_once 'google-api-php-client/src/contrib/Google_DriveService.php';
//create a Google OAuth client
$client = new Google_Client();
$client->setClientId('YOUR CLIENT ID');
$client->setClientSecret('YOUR CLIENT SECRET');
$redirect = filter_var('http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'],
    FILTER_SANITIZE_URL);
$client->setRedirectUri($redirect);
$client->setScopes(array('https://www.googleapis.com/auth/drive'));
if(empty($_GET['code']))
{
    $client->authenticate();
}

if(!empty($_FILES["fileToUpload"]["name"]))
{
  $target_file=$_FILES["fileToUpload"]["name"];
  // Create the Drive service object
  $accessToken = $client->authenticate($_GET['code']);
  $client->setAccessToken($accessToken);
  $service = new Google_DriveService($client);
  // Create the file on your Google Drive
  $fileMetadata = new Google_Service_Drive_DriveFile(array(
    'name' => 'My file'));
  $content = file_get_contents($target_file);
  $mimeType=mime_content_type($target_file);
  $file = $driveService->files->create($fileMetadata, array(
    'data' => $content,
    'mimeType' => $mimeType,
    'fields' => 'id'));
  printf("File ID: %s\n", $file->id);
}
?>
