How to Beautifully Formatted Archives by Month Separated by Year

Are you looking for a way to display a beautifully formatted archives list of months separated by year? While there’s probably a plugin for this, we have created a quick code snippet that you can use to display formatted archives by month separated by year in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

functionwp_custom_archive($args= '') {
    global$wpdb, $wp_locale;
    $defaults= array(
        'limit'=> '',
        'format'=> 'html', 'before'=> '',
        'after'=> '', 'show_post_count'=> false,
        'echo'=> 1
    );
    $r= wp_parse_args( $args, $defaults);
    extract( $r, EXTR_SKIP );
    if( ''!= $limit) {
        $limit= absint($limit);
        $limit= ' LIMIT '.$limit;
    }
    // over-ride general date format ? 0 = no: use the date format set in Options, 1 = yes: over-ride
    $archive_date_format_over_ride= 0;
    // options for daily archive (only if you over-ride the general date format)
    $archive_day_date_format= 'Y/m/d';
    // options for weekly archive (only if you over-ride the general date format)
    $archive_week_start_date_format= 'Y/m/d';
    $archive_week_end_date_format= 'Y/m/d';
    if( !$archive_date_format_over_ride) {
        $archive_day_date_format= get_option('date_format');
        $archive_week_start_date_format= get_option('date_format');
        $archive_week_end_date_format= get_option('date_format');
    }
    //filters
    $where= apply_filters('customarchives_where', "WHERE post_type = 'post' AND post_status = 'publish'", $r);
    $join= apply_filters('customarchives_join', "", $r);

    $output= '

    • ‘

;

        $query= "SELECT YEAR(post_date) AS `year`, MONTH(post_date) AS `month`, count(ID) as posts FROM $wpdb->posts $join $where GROUP BY YEAR(post_date), MONTH(post_date) ORDER BY post_date DESC $limit";
        $key= md5($query);
        $cache= wp_cache_get( 'wp_custom_archive', 'general');
        if( !isset( $cache[ $key] ) ) {
            $arcresults= $wpdb->get_results($query);
            $cache[ $key] = $arcresults;
            wp_cache_set( 'wp_custom_archive', $cache, 'general');
        } else{
            $arcresults= $cache[ $key];
        }
        if( $arcresults) {
            $afterafter= $after;
            foreach( (array) $arcresultsas$arcresult) {
                $url= get_month_link( $arcresult->year, $arcresult->month );
                /* translators: 1: month name, 2: 4-digit year */
                $text= sprintf(__('%s'), $wp_locale->get_month($arcresult->month));

                $year_text= sprintf('

  • %d

‘, $arcresult->year);

                if( $show_post_count)
                    $after= ' ('.$arcresult->posts.')'. $afterafter;
                $output.= ( $arcresult->year != $temp_year) ? $year_text: '';
                $output.= get_archives_link($url, $text, $format, $before, $after);
                $temp_year= $arcresult->year;
            }
        }

    $output.= '‘

;

    if( $echo)
        echo$output;
    else
        return$output;
}
Add this snippet in your index.php file or any other template file where you want to display the formatted archives.
