Snippets by IsItWP

Are you looking for a way to limit the Easy Digital Downloads cart to a fixed quantity? This snippet limits the cart to one item, but you can adjust the limit to any specific number that you wish.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin. Optionally change the limit amount in line 2.

function pw_edd_one_item_checkout( $download_id, $options ) {
	if( edd_get_cart_quantity() >= 1 ) {
		edd_empty_cart();
	}
}
add_action( 'edd_pre_add_to_cart', 'pw_edd_one_item_checkout', 10, 2 );

To limit the cart to 9 items, use this snippet:

function pw_edd_one_item_checkout( $download_id, $options ) {
	if( edd_get_cart_quantity() >= 9 ) {
		edd_empty_cart();
	}
}
add_action( 'edd_pre_add_to_cart', 'pw_edd_one_item_checkout', 10, 2 );
