If your interested in setting up a custom thank you page after someone makes a purchase from your store, (bypassing the standard ‘order received’ page. Simply place the following snippet in your child theme functions php section.
// Redirect custom thank you
add_action( 'woocommerce_thankyou', 'redirectcustom');
function redirectcustom( $order_id ){
$order = new WC_Order( $order_id );
$url = 'http://yoursite.com/my-cool-thank-you-page';
if ( $order->status != 'failed' ) {
echo "<script type='text/javascript'>window.location = '" . $url . "'</script>";
}
}
