Implementing Google Login system in your website is very easy, the Google API Client Library enables us to work with many Google services like Google+, Drive, or YouTube etc. We can also use the library to fetch user details required for registration and login. Today let’s learn how we can use Google API Client Library to make user login and registration system for the website.
Run SQL query below to create a new MySQL table called “google_users” using phpMyAdmin. As you can see we have 5 columns in the table, all are strings (varchar) except for primary field google_id, that’s because Google user IDs are unique numbers and very long ones (21 characters), so we use decimal for that field.
Before you begin, you need client id, secret key from Google API, go to Google API console, create an OAuth client for Web Application, next you will be presented with your Client ID and Secret, which will be required in code below. If you are unsure you can follow these steps.
The process is pretty straight forward, when user clicks Google login link, user is redirected to Google Authentication page, once user grants the basic permission to your application, user is redirected back to your website with Authentication code. The code is than used to obtain Access Token, using Access Token the application can access current user data from Google, which could be used to register and login the user.
That’s it, you can download sample files and look at demo I have created for you. I hope this will be helpful in creating Google connect system for your website. Good luck!
