shortcode / username greeting

Add this to the end of wsl.auth.widget.php

// --------------------------------------------------------------------

function wsl_get_username(){

	global $current_user;

		get_currentuserinfo();

		$user_id = $current_user->ID;

	$display_wsl_username = wsl_get_user_data_by_user_id( "display_name", $user_id );

	return $display_wsl_username;

	 }

add_shortcode ( 'wsl_username', 'wsl_get_username' );

And add [wsl_username] is cool

Hey thank you for your help, but I can’t find that file anywhere when I’m in the edit section of WordPress-Social-Login? There are only 5 *.php files:
wordpress-social-login/wp-social-login.php
wordpress-social-login/hybridauth/index.php
wordpress-social-login/services/siteinfo.php
wordpress-social-login/services/diagnostics.php
wordpress-social-login/services/index.php

Am I looking in the wrong dir/ ?

https://github.com/hybridauth/WordPress-Social-Login/blob/master/includes/widgets/wsl.auth.widget.php

/includes/widgets/wsl.auth.widget.php

Thank you for your help Mel, and thanks for your quick response. I figured it out and that worked great!

How would I be able to get their FB (or any social site) avatar to show as well when they are logged in?

add that on WSLs options page
wp-admin/options-general.php?page=wordpress-social-login&wslp=login-widget Basic > User Avatars > “Display user avatars from social networks when available”
