thank your for your response, spaceshiptrooper…
“adding your app…”
what do you mean exactly… what I need to do is add the domain… is this what you mean? I already have my FB app ID and everything… but it looks like for every domain you want to be able to share that domain has to somehow be “registered” with them…
now there are much simpler ways to share, which is what I had initially done… like this…
<a id="fb" href="https://www.facebook.com/sharer/sharer.php?u=<?php echo $encURL; ?>">share on Facebook</a>
however, this gives you no control as to how the shared pg shows on yr FB timeline… it included copy there I didn’t want, and it didn’t include the content in <h1>...</h1>
which I found pretty incredible…
so I researched this a bit and found there are other ways of doing this… albeit much more complicated, but well, I assumed I should be able to figure it out…
these are the two pages I looked at mostly…
(with what’s here I was able to share, but again, didn’t like how it displayed…)
with this one, FB.ui({.....});
I got the feeling I could get the most control (I looked into this and found, mostly looking @ SO threads, that there are a no. of params you can put there (title, description, etc…) for example
http://stackoverflow.com/questions/22377724/facebook-share-via-fb-ui
but this is the one where I run into the problem of adding the domain… here’s a test page www.fotoartepuertovaras.cl/share-test-2.php
if you hit “share on Facebook” here is where you get that alert about adding the domain… I don’t know where to add this domain (what url…)
sorry for longuish answer… but… am hoping for answers myself…;~)) my site is ready to roll now, but I haven’t “published it” yet (sent the urls to people, posted it on FB, etc…) b/c I want to have the social-media sharing stuff ready first (and I still have to do Twttter, Pinterest, Instagram… but I’ll be happy if I can get FB and TW to work… if I can get those two to work I’ll release it…)
thanks again, spaceshiptrooper…
