tweaking Efficient Related Posts, a WordPress plugin

There are so many plugins for WordPress that it's easy to get carried away and install more than necessary. I hope I've avoided that. I try to limit myself to plugins that can really improve the reader's experience. The other day, I installed Efficient Related Posts [http://wordpress.org/extend/plugins/efficient-related-posts/] (0.3.6). It's a great tool to generate a list of hopefully related posts on my blog. There should even be some listed below this post. ;) Under the settings, you can alter what the header says and even have it auto-generate related posts for every blog post. For example, I changed the header "Related Posts" to "Related Content". But one thing I didn't see the settings offer is a way to hide that header in cases where no related content was generated. In other words, when no related content was generated it was displaying something like "Related Content: no related posts found." I don't want people to see that so I tweaked the code in the main plugin script using WordPress' plugin editor. Here's the code below. It's only a minor change for the "if" block that starts at around line 307. if ( !empty($settings['title']) && !empty($relatedPosts)) { $output = "--------------<h4 class='related_post_title'>{$settings['title']}</h4>{$output}"; /* Nitin Arora modified the code above on 20101219 to display differently. By adding the "&& !empty($relatedPosts)" condition, only posts/pages with related content will show the related content header. A few "-"s were added to offset the related content header for readability. Also, the <h4> tag was originally an <h3>. */ }
