Classipress: create a button to share in facebook after creating an ad
Hi,
is there an easy way to add a button to share in facebook, without installing any plugin?
I just want to place a fb share button at the end of the process of creating an ad, so the user can promote his ad.
I can see that the way to share in fb is with the link "https://www.facebook.com/sharer.php?u=" plus the url of the ad just created, but I don't know how to create a buttón that on click, loads that url + the url of the ad. This must be super simple, but I don't have the knowledge to do it...
Can anybody help??
Thanks!!
