[Plugin: Simple Facebook Connect] shortcodes running twice per page

  • When the simple facebook connect plugin is enabled, shortcodes are being run twice per page (once in the header, once in the body). Here’s why it’s happening:

    • add_action(‘wp_head’,’sfc_base_meta’);
    • sfc_base_meta() calls apply_filters(‘sfc_base_meta’,$fbmeta, $post);
    • add_filter(‘sfc_base_meta’,’sfc_media_handler’, 10, 2);
    • sfc_media_handler() calls apply_filters(‘the_content’, $post->post_content);
      which runs shortcodes if found

    I was able to avoid this by adding my shortcode “later” during the ‘wp_head’ hook (after the sfc plugin ran it’s filter), but I doubt this is an acceptable solution for all other plugins.

    The shortcode is supposed to run twice per page. Maybe three times. Or more. That is by design.

    If your shortcode cannot run twice per page, then you’ve either written it incorrectly or shouldn’t be making it into a shortcode.

    See https://ottopress.com/2011/actions-and-filters-are-not-the-same-thing/ for more information, and be aware that shortcodes are a form of filter.

    I see your point. This is actually for Cart66 not my own plugin, which uses a [checkout] shortcode. Strange things happen when it runs twice on the same page. This will serve as a good reference for others than encounter it.
