Support » Plugin: WordPress Share Buttons Plugin – AddThis » PHP Notice: addthis_social_widget.php:1301 Undefined variable: below_excerpt fix

  • Resolved HongPong


    The latest version of the plugin is not causing any visual errors but it is throwing a notice on one of my custom post type templates. I was able to fix this notice by changing line 1300 to

    } elseif ( isset( $below_excerpt ) && $below_excerpt
    [as the $below_excerpt is apparently null and throwing the notice by being uncheckable]. this didn’t seem to effect the area where I do want the buttons to show – not even on the template w the error.

    NOTICE: wp-content/plugins/addthis/addthis_social_widget.php:1301 - Undefined variable: below_excerpt
    require('wp-blog-header.php'), require_once('wp-includes/template-loader.php'), include('/themes/mytheme/single-mycustomposttype.php'), the_content, apply_filters('the_content'), call_user_func_array, addthis_display_social_widget

    i used the filter to nix the appearance of this on the custom post type. Notice is not appearing on my other custom post types, BTW i narrowed down their display this way:

    function mytheme_addthis_post_exclude_filter($display)
        //_log('filter fires');
        if ( in_array(get_post_type(), array('project', 'bio','mycustomposttype')) )
                $display = false;
        return $display;
    add_filter('addthis_post_exclude', 'fp_callahan_addthis_post_exclude_filter');

  • Also on a search page with no results, this notice occurs :

    Notice: Trying to get property of non-object in /srv/www/callahan/htdocs/wp-content/plugins/addthis/addthis_settings_functions.php on line 430

    That is apparently
    } elseif (is_page($post->ID)) {
    seems like a condition for search pages that includes empty-result ones should be popped in above this line.

    I get the same Warning on my Search Results page.

    We released 5.2.0 earlier today, and these notices should no longer appear in it.

    Please feel free to reach out to us here or at if you still see this happening after upgrading to 5.2.0.
