I'm trying to show the total amount of posts of my WordPress Multisite. For that I'm using the following code, which worked at the beginning. So I guess that there's something wrong with the set_site_transient which should cache the output for a time.

Maybe someone has an idea what my mistake is. I can't find the solution.

Cheers and thanks a lot!

    function posts_count_func( $args ){

    global $wpdb;
    $blogs = $wpdb->get_results( $wpdb->prepare(
            "SELECT * FROM {$wpdb->blogs} WHERE  spam = '0' 
            AND deleted = '0' AND archived = '0' 
            ORDER BY registered DESC, 2", ARRAY_A ) );

    $original_blog_id = get_current_blog_id();

     $args = array(
        'numberposts'     => -1,
        'post_type'       => 'post',
        'post_status'     => 'publish' );
    $total_network = $draft_network = 0;
    $total_sites = 0;

    foreach ($blogs as $blog)
        switch_to_blog( $blog->blog_id );
        $args['post_status'] = 'publish';
        if (count(get_posts($args))<2) { continue; }
        $total_posts = count( get_posts( $args ) );
        $total_network += $total_posts;
        $total_sites += 1;

        $args['post_status'] = 'draft';


        set_site_transient ( 'total_posts_cache', $total_network, 24 * HOUR_IN_SECONDS );

 switch_to_blog( $original_blog_id );

function posts_shortcode_count_func( $atts ){
 return get_site_transient( 'total_posts_cache' );
add_shortcode( 'posts', 'posts_shortcode_count_func' );

You don't seem to call posts_count_func() anywhere, so if your transient expires, it's not getting reset.

function posts_shortcode_count_func( $atts ){
    $post_count = get_site_transient( 'total_posts_cache' );
    if( ! $post_count ) {
        $post_count = get_site_transient( 'total_posts_cache' );
    return $post_count;
add_shortcode( 'posts', 'posts_shortcode_count_func' );

According to the docs for get_transient() (which is the non-network version of get_site_transient()), false is returned if the transient doesn't exist or has expired.

Also: You shouldn't need $args['post_status'] = 'publish'; in your foreach() loop, since you've already set that key=>value pair in your $args array up higher.

  • Ahhh! Yes! Thank you so much! Should I use get_transient() instead of get_site_transient()? – Philipp Jul 13 '13 at 10:29
  • No, for your case, use get_site_transient() -- I linked to get_transient() because the page for get_site_transient() essentially says "See get_transient() for details". – Pat J Jul 13 '13 at 15:51
  • @ Pat J: Thank you very much. I'm still struggeling and opened a new question. If it's possible to you it would be great if you could take another look here: wordpress.stackexchange.com/questions/107244/… – Philipp Jul 20 '13 at 9:15
