no rates displaying

Hi @lewiswolk,

I believe these two snippets should do the job. If you add them to the functions.php file of theme/child-theme your shop is currently using or insert them via e.g. the Code Snippets plugin, the first one:

add_filter( 'woocommerce_package_rates' , 'sort_woocommerce_available_shipping_methods', 10, 2 );
function sort_woocommerce_available_shipping_methods( $rates, $package ) {

	//  if there are no rates don't do anything
	if ( ! $rates ) {
		return;
	}
	
	// get an array of prices
	$prices = array();
	foreach( $rates as $rate ) {
		$prices[] = $rate->cost;
	}
	
	// use the prices to sort the rates
	array_multisort( $prices, $rates );
	
	// return the rates
	return $rates;

}

should result in sorting all the available shipping methods starting from the cheapest one, and the second:

function default_cheapest_shipping_method( $current_chosen_method, $available_methods ) {

		$selection_priority = get_option( 'woocommerce_shipping_method_selection_priority', array() );

		if ( ! empty( $available_methods ) ) {

			// Is a method already chosen?
			if ( ! empty( $current_chosen_method ) && ! isset( $available_methods[ $current_chosen_method ] ) ) {
				foreach ( $available_methods as $method_key => $method ) {
					if ( strpos( $method->id, $current_chosen_method ) === 0 ) {
						return $method->id;
					}
				}
			}

			// Order by priorities and costs
			$prioritized_methods = array();

			foreach ( $available_methods as $method_key => $method ) {
				// Some IDs contain : if they have multiple rates so use $method->method_id
				$priority  = isset( $selection_priority[ $method->method_id ] ) ? absint( $selection_priority[ $method->method_id ] ): 1;

				if ( empty( $prioritized_methods[ $priority ] ) ) {
					$prioritized_methods[ $priority ] = array();
				}

				$prioritized_methods[ $priority ][ $method_key ] = $method->cost;
			}

			ksort( $prioritized_methods );
			$prioritized_methods = current( $prioritized_methods );
			asort( $prioritized_methods );

			return current( array_keys( $prioritized_methods ) );
		}

		return false;  
}

add_filter('woocommerce_shipping_chosen_method', 'default_cheapest_shipping_method', 10, 2);

will make the cheapest one selected by default.

I hope the solution I suggested above helped. Please also mind that if you own an active PRO plugin subscription you can contact us directly with all your questions and doubts at https://flexibleshipping.com/support/
