URL to add to cart multiple products

Hey @calduchoweb,

Out of the box, this isn’t possible. Only one product can be added to the cart at a time with the add-to-cart URL feature.

There is a Stack Overflow post that shows how some users have made this work for them.

https://stackoverflow.com/questions/42570982/adding-multiple-items-to-woocommerce-cart-at-once

I’d take a look at that and see if it will work for you. It appears this answer is more up to date.

Hopefully, that’ll get you pointed in the right direction.

Cheers

Hello @3sonsdevelopment

Many thanks! It is just what I was looking for.
In case someone else helps, the code that has worked for me is the following:

add_action( 'wp_loaded', 'add_multiple_to_cart_action', 20 );

function add_multiple_to_cart_action() {
    if ( ! isset( $_REQUEST['multiple-item-to-cart'] ) || false === strpos( wp_unslash( $_REQUEST['multiple-item-to-cart'] ), '|' ) ) { // phpcs:ignore WordPress.Security.NonceVerification.NoNonceVerification, WordPress.Security.ValidatedSanitizedInput.InputNotSanitized
            return;
        }

    wc_nocache_headers();

    $product_ids        = apply_filters( 'woocommerce_add_to_cart_product_id', wp_unslash( $_REQUEST['multiple-item-to-cart'] ) ); // phpcs:ignore WordPress.Security.NonceVerification.NoNonceVerification
    $product_ids = explode( '|', $product_ids );
    if( ! is_array( $product_ids ) ) return;

    $product_ids = array_map( 'absint', $product_ids );
    $was_added_to_cart = false;
    $last_product_id = end($product_ids);
    //stop re-direction
    add_filter( 'woocommerce_add_to_cart_redirect', '__return_false' );
    foreach ($product_ids as $index => $product_id ) {
        $product_id = absint(  $product_id  );
        if( empty( $product_id ) ) continue;
        $_REQUEST['add-to-cart'] = $product_id;
        if( $product_id === $last_product_id ) {

            add_filter( 'option_woocommerce_cart_redirect_after_add', function() { 
                return 'yes'; 
            } );
        } else {
            add_filter( 'option_woocommerce_cart_redirect_after_add', function() { 
                return 'no'; 
            } );
        }

        WC_Form_Handler::add_to_cart_action();
    }
}

A greeting!
