Hide national/international shipping on free shepping, but keep local pickup

The snippet unsets each method programmatically.

unset( $rates['flat_rate'] );

just don’t unset local pickup.

I use the code from https://docs.woothemes.com/document/hide-other-shipping-methods-when-free-shipping-is-available/

so i have to paste this snippet?

/**
 * woocommerce_package_rates is a 2.1+ hook
 */
add_filter( 'woocommerce_package_rates', 'hide_shipping_when_free_is_available', 10, 2 );

/**
 * Hide shipping rates when free shipping is available
 *
 * @param array $rates Array of rates found for the package
 * @param array $package The package array/object being shipped
 * @return array of modified rates
 */
function hide_shipping_when_free_is_available( $rates, $package ) {

 	// Only modify rates if free_shipping is present
  	if ( isset( $rates['free_shipping'] ) ) {

  		// To unset a single rate/method, do the following. This example unsets flat_rate shipping
  		unset( $rates['local_pickup'] );

	}

	return $rates;
}

You don’t want this line:

unset( $rates['local_pickup'] );

That removes it!

Ok thank you, i resolved with this:

/**
 * woocommerce_package_rates is a 2.1+ hook
 */
add_filter( 'woocommerce_package_rates', 'hide_shipping_when_free_is_available', 10, 2 );

/**
 * Hide shipping rates when free shipping is available
 *
 * @param array $rates Array of rates found for the package
 * @param array $package The package array/object being shipped
 * @return array of modified rates
 */
function hide_shipping_when_free_is_available( $rates, $package ) {

 	// Only modify rates if free_shipping is present
  	if ( isset( $rates['free_shipping'] ) ) {
 unset( $rates['local_delivery'] );
	}

	return $rates;
}
