Hide shipping methods for specific shipping class in WooCommerce

Essentially I'm trying to make the flat rate method Id `flat_rate:7` **disabled** when there is cart items that have the shipping class "Roller" (ID `92`).

**This is the code I tried:**

add_filter('woocommerce_package_rates', 'wf_hide_shipping_method_based_on_shipping_class', 10, 2);

function wf_hide_shipping_method_based_on_shipping_class($available_shipping_methods, $package)
{
$hide_when_shipping_class_exist = array(
92 => array(
'flat_rate:7'
)
);

$shipping_class_in_cart = array();
foreach(WC()->cart->cart_contents as $key => $values) {
$shipping_class_in_cart[] = $values['data']->get_shipping_class_id();
}

foreach($hide_when_shipping_class_exist as $class_id => $methods) {
if(in_array($class_id, $shipping_class_in_cart)){
foreach($methods as & $current_method) {
unset($available_shipping_methods[$current_method]);
}
}
}

return $available_shipping_methods;
}

Shipping class ID **`92`** is the shipping class and I want to hide `flat_rate:7` for it.

My Site is this:

WordPress: 4.8.4
WooCommerce: 3.1.1

Any help will be greatly appreciated.

By tweaking LoicTheAztec's code (cheers), I was able to unset a shipping method for ***each package*** based on the shipping class of its contents, rather than the cart as a whole. Perhaps it will help someone else too:

// UNSET A SHIPPING METHOD FOR PACKAGE BASED ON THE SHIPPING CLASS(es) OF ITS CONTENTS
add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_shipping_class', 10, 2 );
function hide_shipping_method_based_on_shipping_class( $rates, $package )
{
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) {
return;
}

foreach( $package['contents'] as $package_item ){ // Look at the shipping class of each item in package

$product_id = $package_item['product_id']; // Grab product_id
$_product = wc_get_product( $product_id ); // Get product info using that id

if( $_product->get_shipping_class_id() != 371 ){ // If we DON'T find this shipping class ID
unset($rates['wbs:9:dae98e94_free_ups_ground']); // Then remove this shipping method
break; // Stop the loop, since we've already removed the shipping method from this package
}
}
return $rates;
}

This code allows me to unset my 'Free UPS Ground' shipping if the package contains anything but 'Standard' items (shipping_class_id 371 in my case).

The scenario from the original post (disable method ***x*** if shipping class ***y***) would work like this:

// UNSET A SHIPPING METHOD FOR PACKAGE BASED ON THE SHIPPING CLASS(es) OF ITS CONTENTS
add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_shipping_class', 10, 2 );
function hide_shipping_method_based_on_shipping_class( $rates, $package )
{
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) {
return;
}

foreach( $package['contents'] as $package_item ){ // Look at the shipping class of each item in package

$product_id = $package_item['product_id']; // Grab product_id
$_product = wc_get_product( $product_id ); // Get product info using that id

if( $_product->get_shipping_class_id() == 92 ){ // If we DO find this shipping class ID
unset($rates['flat_rate:7']); // Then remove this shipping method
break; // Stop the loop, since we've already removed the shipping method from this package
}
}
return $rates;
}

**Update 2019:** You should try instead this shorter, compact and effective way:

add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_shipping_class', 10, 2 );
function hide_shipping_method_based_on_shipping_class( $rates, $package )
{
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;

// HERE define your shipping class to find
$class = 92;

// HERE define the shipping method to hide
$method_key_id = 'flat_rate:7';

// Checking in cart items
foreach( $package['contents'] as $item ){
// If we find the shipping class
if( $item['data']->get_shipping_class_id() == $class ){
unset($rates[$method_key_id]); // Remove the targeted method
break; // Stop the loop
}
}
return $rates;
}

*Code goes in function.php file of your active child theme (or theme) or also in any plugin file.*

Tested and works.

>Sometimes, you should may be need to refresh shipping methods going to shipping areas, then disable / save and re-enable / save your "flat rates" shipping methods.

Update for many different shipping methods (related to your comments):

add_filter( 'woocommerce_package_rates', 'hide_shipping_method_based_on_shipping_class', 10, 2 );
function hide_shipping_method_based_on_shipping_class( $rates, $package )
{
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;

// HERE define your shipping class to find
$class = 92;

// HERE define the shipping methods you want to hide
$method_key_ids = array('flat_rate:7', 'local_pickup:3');

// Checking in cart items
foreach( $package['contents'] as $item ) {
// If we find the shipping class
if( $item['data']->get_shipping_class_id() == $class ){
foreach( $method_key_ids as $method_key_id ){
unset($rates[$method_key_id]); // Remove the targeted methods
}
break; // Stop the loop
}
}
return $rates;
}

Tested and works…

-------

**Finding the shipping class ID.**

1) In the database under `wp_terms` table:

Search for a term name or a term slug and you will get the term ID (the shipping class ID).

2) On Woocommerce shipping settings editing a "Flat rate", with your browser html inspector tool, inspect a shipping Class rate field like:

In the imput name attribute you have `woocommerce_flat_rate_class_cost_64`. So 64 is the ID for the shipping class.

**Get the shipping method rate ID:**

>To get the related **shipping methods rate IDs**, something like **`flat_rate:12`**, inspect with your browser code inspector each related radio button attribute **`value`** like:
