Grouped Products are part of WooCommerce core and let you “add similar (think materials, design, etc.) products to a single grouped product. This allows the customer to add products […] to their cart on one page instead of navigating to several different pages to do so” (WooCommerce docs).
It may happen during your coding career that you need to know whether a given Product ID is part of a Grouped Product (so, it’s a “child” of a Grouped Product) – the snippet below will help with that. Enjoy!

// GET ALL GROUPED PRODUCTS
$args = array(
'type' => 'grouped',
'status' => 'publish',
'limit' => -1,
);
$products = wc_get_products( $args );
// LOOP THROUGH RESULTS
foreach ( $products as $product ) {
$children = array();
foreach ( $product->get_children() as $child_id ) {
$children[] = $child_id;
}
}
// CHECK IF PRODUCT 123 IS A CHILD
if ( in_array( 123, $children ) ) {
// DO SOMETHING
}
