Should we put $content .=$social_content; on line 25 instead of $content .=$new_content; ?

Is there an error in a code example of how to append sharing content?

I see this is an old question, but this small error still exists in the project files.
Please see 6:59 in the video.
$social_content is the variable with the content to add, but $new_content is used, which isn't defined.

Hi, I don't think so, are you noticing an error?

There's no error, but once you add a plugin header and activate the code on WP 4.2.2, the plugin has no effect until you match up the variable names:

            $social_content = 'Insert in the social sharing code here';
            $content .= $social_content;

shouldnt this error be fixed after this long time? or when its not an error explained?

Just seen this, totally agree - this is an error surely? Concatenating $content with an empty $new_content would do nothing, and $social_content is left alone.

I'm assuming this is a couple of years old now, but this should be fixed, even just in the project download files with a quick note commented out in the PHP.
