Wordpress plugin to add link only

[simon]

Assuming you’re not using SSO, you could try adding something to your theme’s functions.php file that hooks into the WordPress the_content filter.

This works quite well with a theme based off the ‘Twenty Sixteen’ theme. You can change the link text in the function, and customize or remove the $discourse_link_instructions text.

// Your theme's functions.php file.

function your_site_prefix_discourse_link( $content ) {
    global $post;

    if ( is_single() && get_post_meta( $post->ID, 'publish_to_discourse', true ) ) {
        $discourse_permalink         = get_post_meta( $post->ID, 'discourse_permalink', true );
        $discourse_link_instructions = '<p>Leave a comment here, or join the discussion on our forum.</p>';

        return $content . '<div class="discourse-topic-link">' . $discourse_link_instructions . '<a href="' . esc_url( $discourse_permalink ) . '">Comment on our forum</a></div>';
    }

    return $content;
}

add_filter( 'the_content', 'your_site_prefix_discourse_link' );

/* style.css */

    padding-top: 1.75em;
