A dialog box will appear with OAuth client details, note the Client ID and Client secret for later use in the script. This Client ID and Client secret allow you to access the Google Drive API.<\/p>\n
![\"google-api-console-project-oauth-api-key-client-id-secret-codexworld\"](\"https:\/\/www.codexworld.com\/wp-content\/uploads\/2022\/01\/google-api-console-project-oauth-api-key-client-id-secret-codexworld-1024x551.png\")
<\/div>\n
Note that:<\/span> The Client ID<\/b> and Client secret<\/b> need to be specified at the time of the Google Drive API call. Also, the Authorized redirect URIs must be matched with the Redirect URL specified in the script.<\/p>\nCreate Database Table<\/h2>\n
A table is required in the database to store file information on the local server. The following SQL creates a drive_files<\/code> table with some basic fields in the MySQL database.<\/p>\nCREATE<\/span> TABLE<\/span> `drive_files`<\/span> (\r\n `id`<\/span> int<\/span>(11<\/span>) NOT<\/span> NULL<\/span> AUTO_INCREMENT,\r\n `file_name`<\/span> varchar<\/span>(255<\/span>) COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `google_drive_file_id`<\/span> varchar<\/span>(255<\/span>) COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `created`<\/span> datetime NOT<\/span> NULL<\/span> DEFAULT<\/span> current_timestamp<\/span>(),\r\n PRIMARY KEY<\/span> (`id`<\/span>)\r\n) ENGINE<\/span>=InnoDB<\/span> DEFAULT<\/span> CHARSET<\/span>=utf8 COLLATE<\/span>=utf8_unicode_ci;<\/pre>\nGoogle Drive API PHP Library<\/h2>\n
Google provides a PHP client library to make Drive API calls, but it contains many additional services that come with a huge number of files and are large in size. To make the process simple, we will build a custom library to handle the Google Drive API calls with PHP.<\/p>\n
Our Google API Library<\/b> helps to authenticate with Google account and access the Drive API with REST API using PHP cURL. This custom PHP library will use Google Drive v3 API<\/b> to handle the file upload process.<\/p>\n\n- GetAccessToken()<\/b> – Fetch the access token from Google OAuth 2 API using authentication code.<\/li>\n
- UploadFileToDrive()<\/b> – Send file to Google Drive for upload using REST API.<\/li>\n
- UpdateFileMeta()<\/b> – Update metadata of the uploaded file in Google Drive.<\/li>\n<\/ul>\n
