Adding multiple products to cart at once

Please add function.php

function woocommerce_maybe_add_multiple_products_to_cart() {
// Make sure WC is installed, and add-to-cart qauery arg exists, and contains at least one comma.
if ( ! class_exists( 'WC_Form_Handler' ) || empty( $_REQUEST['add-to-cart'] ) || false === strpos( $_REQUEST['add-to-cart'], ',' ) ) {
    return;
}

// Remove WooCommerce's hook, as it's useless (doesn't handle multiple products).
remove_action( 'wp_loaded', array( 'WC_Form_Handler', 'add_to_cart_action' ), 20 );

$product_ids = explode( ',', $_REQUEST['add-to-cart'] );
$count       = count( $product_ids );
$number      = 0;

foreach ( $product_ids as $product_id ) {
    if ( ++$number === $count ) {
        // Ok, final item, let's send it back to woocommerce's add_to_cart_action method for handling.
        $_REQUEST['add-to-cart'] = $product_id;

        return WC_Form_Handler::add_to_cart_action();
    }

    $product_id        = apply_filters( 'woocommerce_add_to_cart_product_id', absint( $product_id ) );
    $was_added_to_cart = false;
    $adding_to_cart    = wc_get_product( $product_id );

    if ( ! $adding_to_cart ) {
        continue;
    }

    $add_to_cart_handler = apply_filters( 'woocommerce_add_to_cart_handler', $adding_to_cart->product_type, $adding_to_cart );

    /*
     * Sorry.. if you want non-simple products, you're on your own.

     *
     * Why you gotta be like that WooCommerce?
     */
    if ( 'simple' !== $add_to_cart_handler ) {
        continue;
    }

    // For now, quantity applies to all products.. This could be changed easily enough, but I didn't need this feature.
    $quantity          = empty( $_REQUEST['quantity'] ) ? 1 : wc_stock_amount( $_REQUEST['quantity'] );
    $passed_validation = apply_filters( 'woocommerce_add_to_cart_validation', true, $product_id, $quantity );

}
}

 // Fire before the WC_Form_Handler::add_to_cart_action callback.
 add_action( 'wp_loaded',        'woocommerce_maybe_add_multiple_products_to_cart', 15 );

Hi Logicrays,

My site broke after adding this. Do you know why by any chance?

Thanks!

Hi

Please check below link

Thanks

Hi Logicrays,

Thanks for your fast reply! Unfortunately it does not work.

Hi @clingendael

Did you get a solution for this? What is the general set up that you’re looking to achieve with this?

@logicrays – posting random snippets to functions.php is never a good idea unless the person knows what is happening.
I’ve seen you’ve contributed a few times to the forums saying very similar “put this in your functions.php file.
Please do help out but if offering a custom code solution, either use the code syntax or link to a Gist or similar service and comment about what is happening in the code.

Thanks,

Hi Doug,

Thanks for your reply!

Unfortunately I am still looking for a solution. The general set up that I am looking for is to select multiple products in my store and adding all selected to the cart at once. Maybe with a checkbox next to the item’s name or something with a similar kind of idea.

I was wondering if this is possible with Woocommerce.

Here is a link to my schoolproject:

Thanks.

Hey @clingendael

Maybe with a checkbox next to the item’s name or something with a similar kind of idea.

Ah! So we have a page on our docs site which might be of help to you – How to Bundle Products.

If you are looking for a more generic option or customized, then I’d recommend reaching out to one of the services on our Customizations page (https://woocommerce.com/customizations/).

Thanks,

We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
