facebook share via url like digg.com

What is the question?

Facebook share for external url in WordPress site, it’s showing the link title from external url; not showing the title which I entered.

But Twitter showing the exact title which I entered as a blog post. But Facebook showing only the external url title. How to solve?

Facebook url for share :
<a href=”
https://www.facebook.com/dialog/feed?
app_id=123456789123456
&display=popup&caption=Wordpress Help
&link=<?php echo urlencode(the_permalink()); ?>&t=<?php echo urlencode(the_title()); ?>
&redirect_uri=https://mywebsite.com
“>Facebook

Twitter code :
&url=<?php echo urlencode(the_permalink()); ?>&via=twitter&related=<?php echo urlencode(“wordpress: themes, plugin”); ?>” title=”Share on Twitter” rel=”nofollow” target=”_blank”>Tweet
