Add parameters for the wp_get_archive function that allows to filter the archive for particular years and months.

[sh4lin]

Right now there is no way to get the monthly archive for particular year

<?php

        // This is what will separate dates on weekly archive links.
        $archive_week_separator = '&#8211;';

        $sql_where = $wpdb->prepare( "WHERE post_type = %s AND post_status = 'publish'", $parsed_args['post_type'] );

In order to do that we have to use the filter to change the where clause as below.

<?php
if ( ! empty( $parsed_args['in_year'] ) ) {
                $year       = absint( $parsed_args['in_year'] );
                $sql_where .= sprintf( ' AND YEAR(post_date) = %1$d', $year );
        }
        return $sql_where;

I am suggesting here to add optional argument that can filter the months for a particular year and weeks for particular month likewise.
