Creating a google plus / digg like social bookmark button
<p>For a client of ours we need to create a share button for his site so that the users of his site can add this button to their blogs / sites and others can click on it and it will just open up a popup asking the user to login (if already logged in, the link bookmark page appears) to the clients site and bookmark it. Can somebody guide me on how to do it with php and javascript?</p>
