Creating a Facebook share button with customized url, title and image

问题

Facebook used to allow custom parameters in the Facebook share button, but it is not working now. What I need is to create a Facebook share button which will have a custom title, url, image, description, etc. It cannot be done using meta tags because there are multiple share buttons on a single page. Each should have a different title, urls, images etc. I heard it can be done using the Facebook app - using app id or something.

I tried this but it's not working:

<a title="send to Facebook" 
  href="http://www.facebook.com/sharer.php?s=100&p[title]=YOUR_TITLE&p[summary]=YOUR_SUMMARY&p[url]=YOUR_URL&p[images][0]=YOUR_IMAGE_TO_SHARE_OBJECT"
  target="_blank">

Unfortunately, it appears that we can't post shares for individual topics or articles within a page. It appears Facebook just wants us to share entire pages (based on url only).

There's also their new share dialog, but even though they claim it can do all of what the old sharer.php could do, that doesn't appear to be true.

And here's Facebooks 'best practices' for sharing.

Use facebook feed dialog instead of share dialog.

Example:

https://www.facebook.com/dialog/feed?app_id=1389892087910588 &redirect_uri=https://scotch.io &link=https://scotch.io &picture=http://placekitten.com/500/500 &caption=This%20is%20the%20caption &description=This%20is%20the%20description

This is the code as 2017:

<i class="fa fa-facebook-square"></i>
<a href="#" onclick="window.open('https://www.facebook.com/sharer/sharer.php?u='+encodeURIComponent(location.href),'facebook-share-dialog','width=626,height=436');return false;">Share on Facebook</a>

Facebook now takes all data from OG metatags.

NOTE: This code assumes you have OG metatags on in site's code.

Crude, but it works on our system:

<div class="block-share spread-share p-t-md">
  <a href="http://www.facebook.com/share.php?u=http://www.voteleavetakecontrol.org/our_affiliates&title=Farmers+for+Britain+have+made+the+sensible+decision+to+Vote+Leave.+Be+part+of+a+better+future+for+us+all.+Please+share!" 
     target="_blank">
    <button class="btn btn-social btn-facebook">
      <span class="icon icon-facebook">
      </span> 
      Share on Facebook
    </button>
  </a>

  <a href="https://www.facebook.com/FarmersForBritain" target="_blank">
    <button class="btn btn-social btn-facebook">
      <span class="icon icon-facebook">
      </span>
      Like  on Facebook
    </button>
  </a>
</div>
