Redirect all Carts to a specific Shop Cart
Each of the Network Shops run their own cart page. This can be changed so the cart link redirects the user to a specific Shop Cart in the network, which is usually the Check-out Shop, when using Single Site Check-out type.
The feature can be achieved through a custom code. The WOOGC_REQUIRED_CART_URL value should be updated with the required shop cart URL:
<?php
define('WOOGC_REQUIRED_CART_URL', '--MainShopDomain--/cart/');
add_action('init', 'custom_init');
function custom_init()
{
ob_start( "custom_ob_callback");
}
function custom_ob_callback( $buffer )
{
$current_site_url = wc_get_cart_url();
$current_site_url = preg_replace('/:[0-9]+/', '', str_replace(array ("https://" , "http://"), "", $current_site_url ));
$current_site_url = trailingslashit( $current_site_url );
$buffer = str_ireplace( $current_site_url, WOOGC_REQUIRED_CART_URL, $buffer);
//jsonencoded replacements
$buffer = str_ireplace( trim( json_encode( $current_site_url ), '"' ) , trim( json_encode( WOOGC_REQUIRED_CART_URL ), '"' ) , $buffer );
return $buffer;
}
?>
*The code should be placed into a custom file on /wp-content/mu-plugins/ or theme functions.php
