In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of usecases of submodules:
- Separate big codebases into multiple repositories.
// check for clear-cart get param to clear the cart, append ?clear-cart to any site url to trigger this | |
add_action( 'init', 'woocommerce_clear_cart_url' ); | |
function woocommerce_clear_cart_url() { | |
if ( isset( $_GET['clear-cart'] ) ) { | |
global $woocommerce; | |
$woocommerce->cart->empty_cart(); | |
} | |
