I am completely new to this field and stackoverflow, so bear with me.
I have created a site in muse (designed not coded, of course),
This is my problem... just stuck in creating a "Fb share button"
But I got an idea
Step 1, when user clicks a button, loads up a lightbox with fb login or share menu
Step 2, when user enter necessary information it is posted on their wall
Step 3, redirect them to another page.
Please help me...
Muse already has in-built features for this kinds, just look into social behind widgets.
Instead of setting up your pages using php this is much more easier.
Also Go to Facebook SDK docs and read more about how to redirect your links.
Its more easier if you follow those instructions instead of creating everything using php, which is much more complicated.
