I am using WP Job manager with Woo Subscriptions.
Now:
I tried this Woocommerce Delete all products from cart and add current product to cart but did not help.
Updated (2 different alternatives):
You should try the following:
add_filter( 'woocommerce_add_to_cart_validation', 'remove_cart_item_before_add_to_cart', 20, 3 );
function remove_cart_item_before_add_to_cart( $passed, $product_id, $quantity ) {
if( ! WC()->cart->is_empty() )
WC()->cart->empty_cart();
return $passed;
}
Code goes in functions.php file of your active child theme (or theme). Tested and works with both ajax-add-to-cart and normal add-to-cart…
Or you can use this different one that will keep in cart the last added item:
// Keep only last cart item
add_action( 'woocommerce_before_calculate_totals', 'keep_only_last_cart_item', 30, 1 );
function keep_only_last_cart_item( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
$cart_items = $cart->get_cart();
if( count( $cart_items ) > 1 ){
$cart_item_keys = array_keys( $cart_items );
$cart->remove_cart_item( reset($cart_item_keys) );
}
}
Code goes in function.php file of your active child theme (or theme). Tested and works
