I am working on a CiviCRM plugin that will act as a unified solution for social media login.

Once someone clicks the Login button which this plugin adds (eg to an event page), he or she is redirected to a new page for further data exchange (eg login on Twitter, Google+ etc).

Is there a way I can get to know from which the button was clicked?

One way is to store the same while clicking the button or send it to the new page as a GET or POST variable. I just wanted to check if we already storing/getting it up somewhere in CiviCRM.

  • Can you tell a little more about what you are trying to accomplish with knowing where you come from? That might help us all to provide you with options? Jul 7, 2015 at 10:53
  • Sid - it might help to add documentation to the README on Github which illustrates your intended flow, as well as the features you're aiming to implement. Did we discuss that a few weeks back? Maybe it's in email or something instead of on Github? Jul 7, 2015 at 21:33

This sounds similar to a payment processor flow (especially the "button" style processors). In those, you typically pass a "return URL" to the remote site, and they would in turn direct your visitor back to the specified URL.

If the return URL needs to be a separate callback (eg an IPN URL), then you might add additional parameters (&return=civicrm%2Fevent%3Fid%3D1%26reset%3D1) to the IPN URL, and the IPN can in turn decode that (civicrm/event?id=1&reset=1) and perform a final redirect to land the user on the page they originated from.

Can you use the superglobal? That is, $_SERVER['HTTP_REFERER']?
