Question

I’m editing a WordPress plugin that provides a suggestion for related blog posts.

Here is a screenshot of how it looks now:

I want it to look exactly like the screenshot, but without the “Gratefulness, Happiness” links … which are just links to categories. Keep the “Recommended for You” and the link to the article, but remove the link to the categories.

If I remove the “foreach ( $siblings as $url => $name )” snippet from the code below, then it gets rid of the categories, but messes up the link to the recommended article.

How should I edit it? To remove the categories but keep everything else?

Note: I’m not sure if this matters for the code below, but the plugin chooses the recommended article based on the previous article in the same category.

       ob_start();
    do_action( 'iworks_upprev_box_before' );
    $value .= ob_get_flush();
    if ( $iworks_upprev_options->get_option( 'header_show' ) ) {
        $value .= '<h6>';
        if ( count( $siblings ) ) {
            $value .= sprintf ( '%s ', __('Recommended for You' ) );
            $a = array(); 
            foreach ( $siblings as $url => $name ) {
            $a[] = sprintf( '<a href="%s" rel="%s">%s</a>', $url, $current_post_title, $name );
            }
            $value .= implode( ', ', $a);
        } else if ( $compare == 'random' ) {
            $value .= __('Read more:', 'upprev' );
        } else {
            $value .= __('Read previous post:', 'upprev' );
        }
        $value .= '</h6>';
    }

It looks like all you need to do is comment out this line or remove it:

$value .= implode( ', ', $a);

You can also comment / remove the following lines of code:

$a = array(); 
foreach ( $siblings as $url => $name ) {
   $a[] = sprintf( '<a href="%s" rel="%s">%s</a>', $url, $current_post_title, $name );
}
