Display "Country" + "State/County" + "City/Town" in single product page.

I vote for this as well.

it would be good to display the location in addition to the shop name on the product page

Hello,
You can use the following snippet (do changes as per your need)-

add_action('woocommerce_product_meta_end', function() {
    global $product;
    $vendor_id = wcfm_get_vendor_id_by_post($product->get_id());
    ?>
    <div class="vendor_singleline_address"><?php echo wcfm_get_vendor_store_address_by_vendor($vendor_id); ?></div>
    <?php
});

Add this code to your child theme’s functions.php
In case you do not have child theme then add code using this plugin – https://wordpress.org/plugins/code-snippets/
Let me know how this goes.
Thanks!

Kindly use this updated snippet-

add_action( 'woocommerce_product_meta_end', function() {
    global $product;
    $vendor_id = wcfm_get_vendor_id_by_post( $product->get_id() );
    $store_user = wcfmmp_get_store( $vendor_id );
    $store_info = $store_user->get_shop_info();
    if ( $store_info['store_hide_address'] == 'yes' || ! wcfm_vendor_has_capability( $vendor_id, 'vendor_address' ) )
        return;
    if ( ! empty( $store_info['address'] ) ) {
        $addr_arr = array();
        $all_countries = WC()->countries->get_countries();
        if ( ! empty( $store_info['address']['country'] ) && ! empty( $all_countries[$store_info['address']['country']] ) ) {
            array_push( $addr_arr, $all_countries[$store_info['address']['country']] );
            if ( ! empty( $store_info['address']['state'] ) )
                array_push( $addr_arr, $store_info['address']['state'] );
            if ( ! empty( $store_info['address']['city'] ) )
                array_push( $addr_arr, $store_info['address']['city'] );
            ?>
            <p class="vendor_singleline_address"><span>Country: </span><?php _e( implode( ", ", $addr_arr ) ); ?></p>
            <?php
        }
    }
} );

Country is not stored as an individual meta. You can get complete vendor setting fields using ‘wcfmmp_profile_settings’ meta like this-
$shop_info = get_user_meta( $vendor_id, 'wcfmmp_profile_settings', true );
It return an array with key name ‘address’, which is again an array stored in the following format-

[address] => Array (
    [street_1] => 
    [street_2] => 
    [city] => 
    [zip] => 
    [country] => IN
    [state] => WB
)

Hope it clarifies everything!
