Minimum cart item quantity for specific product categories in WooCommerce

Question

In WooCommerce, I need to set up a minimum quantity for each item of a product category. I searched the forum and found some code that works fine except it only counts the Q

Answer 1

To make it work for a certain product category item counts in total use this code instead:

add_action( 'woocommerce_check_cart_items', 'wc_min_item_required_qty' );
function wc_min_item_required_qty() {
    $categories    = '30'; // The targeted product category slug or ID
    $max_item_qty  = 10; // Minimum Qty required (for each item)
    $display_error = false; // Initializing

    // Loop through cart items
    foreach(WC()->cart->get_cart() as $cart_item ) {
        
        $product_id    = $cart_item['product_id']; // The product ID
        
    if( has_term( $categories, 'product_cat', $product_id )) {
        $item_quantity += $cart_item['quantity']; // Cart item quantity
    }
        // For cart items remaining to "Pizza" product category
        if( has_term( $categories, 'product_cat', $product_id ) && $item_quantity > $max_item_qty ) {
            
            wc_clear_notices(); // Clear all other notices
            
            // Add an error notice (and avoid checkout).
            wc_add_notice( sprintf( 'We can only take orders of up to 10 burgers per customer', $max_item_qty , $item_quantity ), 'error' );
            break; // Stop the loop
        }
    }
}
