WooCommerce - Hide shipping rates when free shipping is available.

functions.php

<?php
/**
 * Hide shipping rates when free shipping is available.
 * Updated to support WooCommerce 2.6 Shipping Zones.
 *
 * @param array $rates Array of rates found for the package.
 * @return array
 */
function my_hide_shipping_when_free_is_available( $rates ) {
	$free = array();

	foreach ( $rates as $rate_id => $rate ) {
		if ( 'free_shipping' === $rate->method_id ) {
			$free[ $rate_id ] = $rate;
			break;
		}
	}

	return ! empty( $free ) ? $free : $rates;
}

add_filter( 'woocommerce_package_rates', 'my_hide_shipping_when_free_is_available', 100 );

@jamiet @pasztig: I've expanded on the provided function to hide all shipping options, except a custom shipping option I've added through a plugin.
function v161_woocommerce_hide_shipping_method( $rates ) {
$free = array();
$free_shipping = false;

    foreach ( $rates as $rate_id => $rate ) {

        if ( 'free_shipping' === $rate->method_id ) {

            $free[ $rate_id ] = $rate;
            $free_shipping = true;

        }

        if ( $free_shipping == true && 'my_custom_shipping_method' === $rate->method_id ) {
            $free[ $rate_id ] = $rate;
        }

    }

    return ! empty( $free ) ? $free : $rates;
}

Ofcourse you should be able replace the part
'my_custom_shipping_method' === $rate->method_id
with
'flat_rate:5' === $rate->id
or
'My custom shipping option name' === $rate->label

I've not tested the last 2 suggestions, but it should at least set you on the right track

Hello, good afternoon, I need to know how the exact code would be to incorporate, since I have two free shipping limits that I need at the time to display one or the other, depending on the minimum amount of purchase. Thank you so much

Hello,

I would like to use the original code to display free shipping when I don't need to show flat rate anymore : it doesn't work.
I've tried on my local site to remove every other things from my functions.php : it still does not work.

What could be wrong ? I've tried to write my own filter before finding this one, and I couldn't understand what could be wrong.

Still my site is running normally offline and online, with all the other functions and plugins.

The code for free shipping + local pickup didn't work for me, but I found a solution in the WooCommerce docs. Might be helpful for some.

You have saved me out of a 1-week headache, I am grateful

What code to use if you want the shipping price to appear only for class specific and not based on amount spent?

I used the php coding and this is what happen to my Wordpress account = Parse error: syntax error, unexpected '*', expecting end of file in /home/customer/www/nrgispower.com/public_html/wp-content/themes/flatsome-child/functions.php on line 3

Fatal error: Exception thrown without a stack frame in Unknown on line 0

I am unable to login or see my account or website. HELP HELP HELP
