Question

I use a point system plugin for WordPress. By adding this code to the author.php page:

<?php cp_displayPoints($authordata->ID); ?>

It will echo X Points. This is the points of that respective author. When I add the same code to single.php (post page), it echos the logged in user’s points, and if not logged in, it returns blank.

How can I alter this code so that it will function properly on the single.php page too? This would mean that it would echo the points of the author of that post.

Answer 1

Just call get_the_author_meta from within the loop.

So, you just need to test if you have a currently signed in user, if not use the post author instead. Something like this.

<?php
if(!$authordata->ID)
  cp_displayPoints(get_the_author_meta('ID'));
else
  cp_displayPoints($authordata->ID);
?>

EDIT:

To display only the post author’s ID, just use

<?php cp_displayPoints(get_the_author_meta('ID')); ?>
