Dear Kevin,
Thanks for using our plugin and for the suggestion.
You are very correct. By using just “https://www.tumblr.com/share” in the url works well allowing users to share not just title but also photos, videos and many more. We will definitely make this change in the upcoming version of our plugin.
But we would also like to add that the current url for Tumblr share button in the plugin is working fine. We have tested it on our development server.
Below is the PHP code for sharing link generated from the official button generator page of tumblr(https://www.tumblr.com/buttons)
<a href="https://www.tumblr.com/share/link?url=<?php echo urlencode(INSERT_URL_HERE) ?>&name=<?php echo urlencode(INSERT_NAME_HERE) ?>&description=<?php echo urlencode(INSERT_DESCRIPTION_HERE) ?>" title="Share on Tumblr" style="display:inline-block; text-indent:-9999px; overflow:hidden; width:81px; height:20px; background:url('https://platform.tumblr.com/v1/share_1.png') top left no-repeat transparent;">Share on Tumblr</a>
If you remove the inline styling, description parameter and title attribute the above code simplifies as below
<a href="https://www.tumblr.com/share/link?url=<?php echo urlencode(INSERT_URL_HERE) ?>&name=<?php echo urlencode(INSERT_NAME_HERE) ?> >Share on Tumblr</a>
This is how our plugin uses the share button link.
Thanking you once again for your suggestions,
Perials Team.
