Bookmarklet

I would like to create a bookmarklet feature similar to the PIN It feature on Pinterest and a small php script to accompany it: - users must be logged into my site - when they click the button, the URL of the page they are visiting will be submitted to my site as a link using a personalized URL created using htaccess and then the link is shared on a Facebook or Twitter For example: - If user is at [login to view URL], they will click the bookmarklet. - (1) if user is logged into my site, the script will create an url like: [login to view URL], which will take the title from [login to view URL] website and create an entry in the db for this member and this URL (google,com) (2) if user is NOT logged into my site, the script will create an url like: [login to view URL] - In a 2nd step, they will then be asked to authorize a share on fb or twitter and once they do, the script will share [login to view URL] with the title and description taken form the page ([login to view URL]) - When someone clicks that link, they are taken to a template ( I will provide) that will simply show the link [login to view URL] on it so I will need the shared url to be added to the template as a dynamic variable
