Adding 'sort by' drop down on custom page using woocommerce short code

问题

I have created a custom page using woocommerce short code for product categories. At the moment, it's pretty sparse as I've only just started on the new site.

I just need the default 'sort by' drop down element adding but have no idea how to do it.

I found some code here >>Woocommerce, sort dropdown on shortcode based product lists

and it certainly placed the drop down I need on the site (although I'd like it aligned left).

The only problem now, is that it's displaying the products with enormous images and all in a single vertical column.

I'm not a PHP programmer and am wondering if I've deleted some important code in the php file I modified. (thank god I took a copy of the original!).

Can anyone help? Is there a better way to add the sort by drop down onto my custom pages?

This is one of the pages I've created >> http://www.sdmtest1.co.uk/notebooks-journals/

Here is the code I added.

/**
 * List products in a category shortcode
 *
 * @param array $atts
 * @return string
 */
public static function product_category( $atts ) {
    $atts = shortcode_atts( array(
        'per_page' => '12',
        'columns'  => '4',
        'orderby'  => 'title',
        'order'    => 'desc',
        'category' => '',  // Slugs
        'operator' => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
    ), $atts );

    if ( ! $atts['category'] ) {
        return '';
    }

    // Default ordering args
    $ordering_args = WC()->query->get_catalog_ordering_args( $atts['orderby'],    
$atts['order'] );
$orderby = 'title';
$order = 'asc';
if ( isset( $_GET['orderby'] ) ) {
    $getorderby = $_GET['orderby'];
}
if ($getorderby == 'popularity') {
    $orderby = 'meta_value_num';
    $order = 'desc';
    $meta_key = 'total_sales';
} elseif ($getorderby == 'rating') {

    $fields .= ", AVG( $wpdb->commentmeta.meta_value ) as average_rating ";

    $where .= " AND ( $wpdb->commentmeta.meta_key = 'rating' OR $wpdb->commentmeta.meta_key IS null ) ";

    $join .= "
        LEFT OUTER JOIN $wpdb->comments ON($wpdb->posts.ID = $wpdb->comments.comment_post_ID)
        LEFT JOIN $wpdb->commentmeta ON($wpdb->comments.comment_ID = $wpdb->commentmeta.comment_id)
    ";

    $orderby = "average_rating DESC, $wpdb->posts.post_date DESC";

    $groupby = "$wpdb->posts.ID";   

} elseif ($getorderby == 'date') {
    $orderby = 'date';
    $order = 'desc';
} elseif ($getorderby == 'price') {
    $orderby = 'meta_value_num';
    $order = 'asc';
    $meta_key = '_price';
} elseif ($getorderby == 'price-desc') {
    $orderby = 'meta_value_num';
    $order = 'desc';
    $meta_key = '_price';
}
$args = array(

}

I edited in dreamweaver and it flagged a syntax error. I wasn't sure where the code I pasted was to begin and end and I kinda lost this bit in the process.

        // Remove ordering query arguments
    WC()->query->remove_ordering_args();

    return $return;
}

Thanks, Loren
