Facebook Like button visibility control

hide Like button if visitor is not a Facebook member

[nimonogi]

Hello,

I have successfully embed a Facebook Like button to my ecommerce website.
Visitors can click Like on each product and a link is posted on their facebook's profile page.

What i want is to control the visibility of the button...
For ex. If the visitor does not have a facebook cookie (i'm not sure which cookie determines that the visitors is a facebook member), i don't want the Like button to appear.

Any ideas on how to do that?

Thanks.

Hi there nimonogy,

You need a conditional clause, once you know the name of the cookie you just say something like:-
If(cookie is set){
//Show button
}

No need for an else clause as you only need the condition to evaluate true if cookie set.

If the visitor does not have a facebook cookie

Security policy of browsers will not allow you to read a cookie set by another site. This can't be done (and if there's a way, it's only a "black hat" way.) Imagine what would happen if I could read all the cookies in your browser from my web site. Well not me, but . . . yeah.

If it is possible at all, the place to find the answer would be the facebook developer forums.
