Is this plugin error related to the Habari version?

[mmynsted]

When attempting to activate the plugin I see only a blank page and plugin does not get activated.

SITE INFORMATION
Habari Version: 0.9-alpha
Habari API Version: 4956
Habari DB Version: 5101

The following is from the php_error.log

It's a very old plugin that hasn't been updated since about 0.6 was released. You can try just removing the info() function in share.plugin.php.

[mmynsted]

So I forked this to mmynsted/share, then removed the info() function. This permits the plugin to be activated.
I updated my theme to include the following in the head

<?php if ($request->display_entry && isset($post)) 
{
    $theme->show_share_metadata($post);
 } ?>

However the actual content for the provided share_metadata.php is never shown. The

$theme->show_share_metadata($post); 

method is called but nothing is displayed.

Now I never setup any facebook admins (was not sure what this was all about) from the configuration dialog, but it does not look required.

I was really just looking for the Open Graph Protocol parts of the share_metadata.php.
It looks like this plugin should be working...

I'm not sure where you're putting this, but presumably it should be along with the post in your post.php template file (if you have one). Otherwise, the only thing I see missing is that you need to echo the contents: echo $theme->show_share_metadata( $post )

[mmynsted]

oh. I just cut and pasted the code from the help in the share.plugin.xml.
That makes sense. I will try it.

[mmynsted]

Adding the echo worked! The description is not populated but the other fields that I would expect to be populated are populated.

Looks like the description is populated via:

  public function theme_get_post_description($theme, $post) {                                                                                                                                                                                                             
                $content = explode('. ', strip_tags($post->content));                                                                                                                                                                                                           
                return $content[0] . '.';                                                                                                                                                                                                                                       
        }  

I am not sure exactly what that does.
