additional add to cart button with fixed quantity in woocommerce single product pages

Question

With woocommerce enabled, we sell wine on our e-shop.

I would like an additional button so that customer can buy a case of wine (12 bottles) rather than having to s

Answer 1

It can be done easily with a custom hooked function displaying an additional button that will add 12 products on 1 click on single product pages for simple products only:

add_action( 'woocommerce_after_add_to_cart_button', 'additional_simple_add_to_cart', 20 );
function additional_simple_add_to_cart() {
    global $product;

    // Only for simple product type
    if( ! $product->is_type('simple') ) return;

    $href = '?add-to-cart=' . esc_attr( $product->get_id() ) . '&quantity=12';
    $class = 'ingle_add_to_cart_button-12 button alt';
    $style = 'display: inline-block; margin-top: 12px;';
    $button_text = __( "Add a case of 12", "woocommerce" );

    // Output
    echo '<br><a rel="no-follow" href="'.$href.'" class="'.$class.'" style="'.$style.'">'.$button_text.'</a>';
}

Code goes in function.php file of your active child theme (active theme).

Tested and works.

Answer 2

this is a help site designed for coders that hit a wall, not really a substitute for using quick google search and the many free pages and tutorials on managing and tweaking such a popular third party platform.

For example, searching google for "woocommerce custom add to cart button" showed how to affect the urls and text, and a search for "woocommerce add custom button" showed how to add extra ui buttons in various pages.

And as others posted here, there also appears to be many plugins making that even simpler, a few of which show up in those searches i listed above, such as "min/max quantity"

Please see https://stackoverflow.com/help/how-to-ask if you try implementing those, hit a wall and cant find anything (after searching for a while) to work around it.

Hope that helps too
