[php] How to pass a parameter like title, summary and image in a Facebook sharer URL

Question:

I need to pass my content like title, summary and image in a Facebook sharer URL like this:

 <a id="button"
    href="http://www.facebook.com/sharer.php?
    s=100
    &p[url]=http://myurl.com/overview/sap-talent
    &p[images][0]=http://myurl/images/my_image.png
    &p[title]=mytitle
    &p[summary]=containsummary">

The problem is it's automatically getting some content from the above mentioned URL (http://myurl.com/overview/sap-talent), and I don't know where my title and summary data are gone. Is there another way to share my custom title, summary and image via facebooksharer.php?

This works at the moment (Oct. 2016), but I can't guarantee how long it will last:

https://www.facebook.com/sharer.php?caption=[caption]&description=[description]&u=[website]&picture=[image-url]

It seems that the only parameter that allows you to inject custom text is the "quote".

https://www.facebook.com/sharer/sharer.php?u=THE_URL&quote=THE_CUSTOM_TEXT

I've used the below before, and it has worked. It isn't very pretty, but you can alter it to suit your needs.

The following JavaScript function grabs the location.href & document.title for the sharer, and you can ultimately change these.

function fbs_click() {
        u=location.href;
        t=document.title;
window.open('http://www.facebook.com/sharer.php?u='+encodeURIComponent(u)+'&t='+encodeURIComponent(t),
                'sharer',
                'toolbar=0,status=0,width=626,height=436');

            return false;
        }

Usage:

<a rel="nofollow" href="http://www.facebook.com/share.php?u=<;url>" onclick="return fbs_click()" target="_blank">
    Share on Facebook
</a>

It looks like this is what you could possibly be looking for: Facebook sharer title / desc....

On the Developers bugs Facebook site, the last answer about that (parameters with sharer.php), makes me believe it was a bug that was going to be resolved. Am I right?

The only parameter you need right now is ?u=<YOUR_URL>. All other data will be fetched from page or (better) from your open graph meta tags:

<meta property="og:url"                content="http://www.nytimes.com/2015/02/19/arts/international/when-great-minds-dont-think-alike.html" />
<meta property="og:type"               content="article" />
<meta property="og:title"              content="When Great Minds Don’t Think Alike" />
<meta property="og:description"        content="How much does culture influence creative thinking?" />
<meta property="og:image"              content="http://static01.nyt.com/images/2015/02/19/arts/international/19iht-btnumbers19A/19iht-btnumbers19A-facebookJumbo-v2.jpg" />
