- The code below demonstrates how to implement OAuth authentication on a PHP-based website.
- As soon as the first line is executed, an array named $config is created to hold all configuration information.
- "base_url" specifies where the user will be redirected after successfully completing authentication in the $config array.
- As part of the "providers" array, a variety of OAuth providers such as Google, Facebook, and Twitter are listed, along with the configurations of each of their services.
- An authentication process is enabled by setting the "enabled" key-value pair to true for every OAuth provider.
- The client ID & client secret you acquired from your OAuth provider's developer dashboard can be found in the "keys" key.
- Debug logging is disabled by setting the "debug_mode" key to false, and enabled by setting it to true.
- When logging is enabled, "debug_file" specifies the file path to which the logs will be written.
- Following that, we have the following HTML file, which displays the logos of Facebook, Twitter, and Google for logging in. There is a title displayed in the browser tab, "Login With Facebook Twitter and Google using PHP - TalkersCode".
- Inside the body, a div element has the align attribute set to "center" so that the inside content will be aligned in the center.
- There is a heading and a subheading within the h1 element: "Facebook, Twitter, and Google integration using PHP".
- The next set of elements consists of three links (a elements) surrounded by images of the Facebook, Twitter, and Google logos. There are several links that point to the same login.php file, but each one has different parameters associated with it. Parameters indicating the social media provider that a user would like to log in with are listed here.
- For example, the Facebook login link includes "?provider=Facebook" at the end of the login.php file path. Additionally, the Twitter link has the "?provider=Twitter" and the Google link has the "?provider=Google" parameters.
- If a user clicks on any of these links, they will be redirected to the login.php file with the appropriate provider parameter passed along. A link will be provided in this file that will handle the login process with the selected social media platform and direct the user to the appropriate page once they have logged in.
