To implement Google sign-in on the website, we need to ensure that the Google API client library is loaded, the front-end includes the Google sign-in button and handles the sign-in process, and the back-end handles the OAuth callback, user session management, and user database updates.
Google_client.php
in application/libraries
.$autoload['libraries']
array.$autoload['libraries'] = array('template', 'database', 'session', 'email', 'table', 'form_validation', 'google_client');
login.js
.function initGoogleSignIn() {
gapi.load('auth2', function() {
gapi.auth2.init({
client_id: 'YOUR_CLIENT_ID.apps.googleusercontent.com'
});
});
}
$(document).ready(function() {
initGoogleSignIn();
});
function onSignIn(googleUser) {
var id_token = googleUser.getAuthResponse().id_token;
$.ajax({
url: base_url + "Login_Controller/google_login",
type: "POST",
data: { id_token: id_token },
success: function(response) {
console.log(response);
},
error: function(xhr, status, error) {
console.error(xhr.responseText);
}
});
}
function signOut() {
var auth2 = gapi.auth2.getAuthInstance();
auth2.signOut().then(function () {
console.log('User signed out.');
});
}
config.php
file.$config['google_client_id'] = 'your-google-client-id';
$config['google_client_secret'] = 'your-google-client-secret';
$config['google_redirect_uri'] = 'your-redirect-uri';
$config['google_scopes'] = array(
'https://www.googleapis.com/auth/userinfo.email',
'https://www.googleapis.com/auth/userinfo.profile',
);
$config['google_auth_endpoint'] = 'https://accounts.google.com/o/oauth2/auth';
$config['google_token_endpoint'] = 'https://accounts.google.com/o/oauth2/token';
$config['google_userinfo_endpoint'] = 'https://www.googleapis.com/oauth2/v3/userinfo';
google_oauth_callback
method to handle the OAuth callback.public function google_oauth_callback() {
$this->load->library('google_client');
$auth_code = $this->input->get('code');
$access_token = $this->google_client->fetchAccessTokenWithAuthCode($auth_code);
$google_profile = $this->google_client->getUserProfileInfo($access_token);
$user = $this->login_mdl->find_or_create_user($google_profile);
$_SESSION['logged_in'] = true;
$_SESSION['user_id'] = $user->id;
redirect('dashboard');
}
<!-- Google Sign-in Button -->
<div class="g-signin2" data-onsuccess="onSignIn" data-theme="dark"></div>
<script src="https://apis.google.com/js/platform.js" async defer></script>
<script>
// JavaScript code from assets/js/login.js
</script>
public function find_user_by_google_id($google_id) {
// Code to find user by Google ID
}
public function create_user_with_google($google_data) {
// Code to create a new user with Google data
}
public function update_user_with_google($user_id, $google_data) {
// Code to update an existing user with Google data
}
After implementing these changes, test the application to ensure that the Google sign-in process works correctly, including user authentication, session management, and database updates.

Hey @autopilot implement a Google sign-in on my website. Make changes to the front end and the back end of the application
To implement Google sign-in on your website, you'll need to make changes to both the front end and the back end. Here's a step-by-step guide to help you through the process:
Include the Google Platform Library in your HTML file:
<script src="https://apis.google.com/js/platform.js" async defer></script>
Add the Google sign-in button to your login page:
<div class="g-signin2" data-onsuccess="onSignIn" data-theme="dark"></div>
Create a JavaScript file (e.g., login.js
) to handle the sign-in process:
function onSignIn(googleUser) {
var id_token = googleUser.getAuthResponse().id_token;
// Send the ID token to your server with an AJAX call
$.ajax({
url: '/path/to/your/backend', // Replace with your server endpoint
type: 'POST',
data: { id_token: id_token },
success: function(response) {
// Handle the successful authentication here
},
error: function(xhr, status, error) {
// Handle errors here
}
});
}
function signOut() { var auth2 = gapi.auth2.getAuthInstance(); auth2.signOut().then(function () { // Handle sign out }); }
$(document).ready(function() { gapi.load('auth2', function() { gapi.auth2.init({ client_id: 'YOUR_CLIENT_ID.apps.googleusercontent.com' // Replace with your client ID }); }); });
4. **Include the JavaScript file** in your login page:
```html
<script src="/path/to/assets/js/login.js"></script>
Install the Google API Client Library for your server-side language (e.g., PHP, Node.js, Python).
Configure your server to handle the authentication with Google:
Store Google API credentials in your server configuration:
// Example for PHP
$config['google_client_id'] = 'your-google-client-id';
$config['google_client_secret'] = 'your-google-client-secret';
$config['google_redirect_uri'] = 'your-redirect-uri';
Handle the OAuth callback on your server:
// Example for PHP
public function google_oauth_callback() {
// Your code to handle the callback
}
Update your user model to handle Google account information:
// Example for PHP
public function find_or_create_user($google_profile) {
// Your code to find or create a user
}
After implementing these changes, test the entire flow to ensure that users can sign in using their Google account and that their sessions are being managed correctly. Remember to replace placeholders like YOUR_CLIENT_ID
with your actual Google client ID and adjust the paths and variable names to match your application's structure.
