WooCommerce: Sort Shipping Costs from Low to High

A client had several shipping rated on the cart page, automatically generated from FedEx, USPS, UPS and similar plugins via their API. Problem was, he wanted to sort them by price as opposed to grouping them by provider.

function businessbloomer_sort_shipping_methods( $rates, $package ) {
  
    if ( empty( $rates ) ) return;
 
    if ( ! is_array( $rates ) ) return;
  
    uasort( $rates, function ( $a, $b ) { 
	if ( $a == $b ) return 0;
	return ( $a->cost < $b->cost ) ? -1 : 1; 
    } );
  
    return $rates;

}

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.

  1. Hi… this code that worked great at first but we have 2 different types of free shipping and it’s only sorting one of them to the top… any idea on how to fix that? Here is an example of what I mean…. if you add any nappies to the basket that total over $99 free shipping is listed and is shown first just as should be – Green Kids Free Shipping.
    BUT… if you add drytimes incontinence products to the basket that total over $29 (free shipping threshold for that product line – make sure no nappies are in the cart or free shipping doesn’t turn on) and the Dry Times Free Shipping does not appear first but gets pushed back to last again. Any ideas why??

    1. Hello Amanda, thanks for your comment ๐Ÿ™‚ Are you using a custom plugin for free shipping?

  2. Even with your January 10 comment and update, my error log is still full of this error as a result of this code:

    [12-Mar-2019 22:54:34 UTC] PHP Warning: array_keys() expects parameter 1 to be array, null given in /home/account/public_html/wp-content/plugins/woocommerce/includes/wc-cart-functions.php on line 468

    Any ideas?

    1. Hey Nathan, I’ve revised the snippet. Can you try this version please?

    2. I tried that revised snippet and unfortunately there’s no difference.

      1. Sure it’s my snippet? Those 2 functions are not “directly” inside it, unless they are called from somewhere else

  3. It breaks some stores because it resets the indexes

    replace with

    uasort($rates, function ($a, $b) { return $a->cost – $b->cost; });
    return $rates;

    1. Thanks for that Chris, much appreciated!

    2. @Chris Awesome you’re the man. This was problem on my store when sorting shipping options. You’d select shipping option from /cart page, it would appear to make ajax call and then it would deselect option & total would not get updated. uasort did the trick. Thank you!

  4. Hi Rodolfo,

    Your snippet does what it is supposed to. However, in the cart, I get these warnings:

    Warning: array_keys() expects parameter 1 to be array, null given in /home/ballsnba/public_html/wp-content/plugins/woocommerce/includes/wc-cart-functions.php on line 465

    Warning: current() expects parameter 1 to be array, null given in /home/ballsnba/public_html/wp-content/plugins/woocommerce/includes/wc-cart-functions.php on line 437

    Warning: array_keys() expects parameter 1 to be array, null given in /home/ballsnba/public_html/wp-content/plugins/woocommerce/includes/wc-cart-functions.php on line 465

    Warning: current() expects parameter 1 to be array, null given in /home/ballsnba/public_html/wp-content/plugins/woocommerce/includes/wc-cart-functions.php on line 437

    This doesn’t bother me except I don’t want my customers to see this! Any ideas? (Caveat: I know nothing about coding; I just paste what I am given into relevant files.)

    Thanks for your help.

    1. Hello Richard, thanks for your comment! First of all, those error messages should be hidden – please use this instead: https://codex.wordpress.org/Debugging_in_WordPress#Example_wp-config.php_for_Debugging

      In regard to the errors themselves, it could be you only have one shipping method in certain cases, and therefore you have no array. I’ve now added a new line to the snippet (is_array) to avoid this – let me know if those errors go away ๐Ÿ™‚

  5. Thanks for the snippet. I tried yours and several other people’s snippets. I could not get my shipping to sort from low to high.

    Then I saw this and did it. Now it works! Great! and thanks for the snippet. ๐Ÿ™‚

    1. Excellent ๐Ÿ™‚

  6. Hi Rodolfo,

    It works now. Just cleared the cache and cart items. Thanks and Sorry

  7. Hello Rodolfo,

    Thanks for the hook. I added this function into my theme’s functions.php but its not showing the price from low to high. I am using WooCommerce 3.2.6. Any idea?

    Rams

  8. Heads up… this seems to break “WooCommerce Advanced Shipping” with WP 4.9.4 (and possibly earlier)

    Not sure why but developer informed.

    1. Hi Martin, thanks for that! My snippets work for default WooCommerce and might not be compatible with third party plugins, so not sure there I’m afraid. I just retested this snippet in Woo 3.3.3 and it still works ๐Ÿ™‚
