Description
On October 14, 2015, LinkedIn converted all groups to private,
which has made the groups display functionality of this plug-in
impossible. However, the Sign in with Linked functionality still
works perfectly fine. The associated sign-in and registration hooks
offer great flexibility for utilizing user data in custom coding.
This plugin is deprecated. Please use RDP Linkedin Login.
RDP inGroups+ provides:
Login button shortcode – shows a Sign in with LinkedIn button when logged out
Member Count shortcode, with the ability to designate a link URL
Ability to register a visitor with the WordPress installaton
Logged-in session security using nonces and client IP address
OOP with hooks and filters for easy integration and customization
Ability to add a list of company IDs that a registered user will automatically follow
Warning About Caching
This plug-in will not work if caching is enabled on a web site.
Sponsor
This plug-in brought to you through the generous funding of Laboratory Informatics Institute, Inc.

Redirect Code Example
In this example, all links with class rdp_jb_must_sign_in are assigned an event listener that sets a cookie, with the cookie value derived from the link’s href attribute.
When the popup login window executes its close script, the cookie is read, and the parent window is redirected to the appropriate URL.
Code in custom sign-in JavaScript file
var $j=jQuery.noConflict();
// Use jQuery via $j(…)

$j(document).ready(rdp_sign_in_onLoad);

function rdp_sign_in_onLoad(){
$j(‘#rdp-jb-main’).on( “click”, ‘.title.rdp_jb_must_sign_in’ , function(event){
event.preventDefault();
var redirectURL = $j(this).attr(‘href’);
jQuery.cookie(‘rdp_lig_login_redirect’, redirectURL, { path: ‘/’ })
});
}//rdp_sign_in_onLoad
