If you want to include the fb like button by using the iFrame approach
you also may want to refer to the actual (current) page when a user
clicks on the button. In the following I present a simple solution to realize
this for php based sites. For sure it is possible to make this shorter but I
thinks it is better to read (p.s. in total this are three lines, had to wrap
cause of the length of the lines).

 
        

        

        

        '; ?>
