I'm using a little plugin that allows me to add source link to every article. I found the code in this thread: Article source link for posts

It's almost perfect, but I need to make 2 little modifications:

  1. When there's no source link, the word "Source:" is still showing up (here's how it looks like: https://i.sstatic.net/qOt5T.png), but I need to get rid of it if no source link is added. Does anyone have any idea how to do it?

  2. Source link shows on every page of a post. I have some posts splitted into multiple pages, but the link still shows on each one of them. I need to change this - the link has to show up only on the last page of a splitted post. Any ideas how to achieve that?

Here's the code I'm using (pasted in functions.php): Article source link for posts - the first one

And here's what I have in my single.php (single post):

<div class="source-link">Source: <?php echo esc_url( get_post_meta( $post->ID, '_source_link', true ) ); ?></div>

Thanks in advance. Im desperate for help.

You can do it like so: (use this in place of the one in the question)

global $post, $pages, $page;

$total = count( $pages );
// Show if there's only one page, or that we're on the last page.
if ( $total < 2 || $page === $total ) :
    // Show if the source link was specified.
    if ( $url = get_post_meta( $post->ID, '_source_link', true ) ) :
        <div class="source-link">
            Source: <?php echo esc_url( $url ); ?>
    <?php endif; // end $url
endif; // end last page check
  • Thank you! Can you just tell me where should I paste it? I don't wanna to break the site (I'm a beginner)
