How to add social login function to WordPress plug-in

In today’s social media era, social login has become a standard feature of many websites. As a widely used content management system, WordPress naturally needs to provide social login functions to enhance user experience. This article will explain how to add social login functionality to a WordPress plugin and provide corresponding code examples.

Step One: Choose a Social Login Plug-in

Before starting to add the social login function, we need to choose a suitable plug-in to complete this task. There are many WordPress social login plug-ins on the market, such as WordPress Social Login, Super Socializer, etc. Choose the right plugin based on your needs and preferences, then install and activate it.

Step 2: Register a social media developer account

Every social media platform requires developers to register and create an application to implement social login functionality. Therefore, before proceeding, we need to go to each social media developer platform, such as Facebook Developer Platform, Twitter Developer Platform, etc., register and create an application.

Step 3: Obtain the API key and key password of the social media application

After successfully registering and creating the application, Social Media will provide us with an API key and Key password, this is important information for us to configure social login in WordPress plugin. We need to find the settings page of the just installed social login plug-in in the WordPress backend and enter this information.

Step 4: Add the social login button to the login page

After the social login plug-in is installed and configured, we need to modify the WordPress login page to add the social login button. Open the login page template of the WordPress theme (usually login.php or wp-login.php) and insert the following code at the required location:

<?php do_action( 'wordpress_social_login' ); ?>

This code snippet will automatically generate all configured social login buttons .

Step 5: Process social login callback

When the user chooses to log in using the social login button, the social media will call back to our website and provide the user's relevant information. We need to add the following code to the WordPress function file (usually functions.php) to handle these callbacks:

function custom_social_login_callback( $user_data ) {
   // 处理用户信息逻辑
}

add_action( 'wordpress_social_login', 'custom_social_login_callback' );

In the custom custom_social_login_callback function, we can handle users as needed Information logic, such as creating new users, updating user information, etc.

Step 6: Display social media avatar and username

After completing the social login, the user’s social media avatar and username are very useful information. We can use the following code to display this information on the user profile page or other appropriate locations:

$user_id = get_current_user_id();
$user_avatar = get_avatar( $user_id );
$user_display_name = get_user_meta( $user_id, 'display_name', true );

echo $user_avatar;
echo $user_display_name;

These codes will output the user's social media avatar and username.

Through the above steps, we can easily add social login functionality to WordPress plug-in. Of course, the specific implementation will vary depending on the plug-ins and social media platforms we choose, so adjustments and modifications will need to be made based on the specific situation. Hopefully this article has given you some help in understanding how to add social login functionality to your WordPress plugin.
