WooCommerce Wordpress can't find total order after checkout/pyament - php

Question

I use a custom payment, which I display in an iframe and pass on variables into a form.
I need to pass the total order without currency sign after checkout/payment.
I've found a way to pass the cart total before checkout/payment using
echo WC()->cart->total
On the checkout after payment page (thankyou.php) I've found
echo $order->get_formatted_order_total();
This will display the total order with a currency sign only on the thankyou.php page and will not pass onto any other page no matter what i tried (which isn't important as I can work with ether thankyou.php page or actual checkout page)
Full code looks like this inside a list
<?php _e( 'Total:', 'woocommerce' ); ?>
<strong><?php echo $order->get_formatted_order_total(); ?>
I've tried testing to see how wordpress stores order total both on thankyou.php page and on a seperate page to see if I can call the order total from the array after checkout/payment but I ether get a value of 0.00 or my page breaks
Code I tried so far:
echo $order->get_order_total();
this breaks the page
echo WC()->$order->get_order_total();
this breaks the page
echo $order->get_total();
this also breaks the page
calling total cart echo WC()->cart->total after checkout/payment will display 0 (which makes sense)

Answer 1

If it's the thank you page, then it's simple enough - you just need to use this and it should work without breaking the page.
In your templates/checkout/thankyou.php file, add this code:
if ( ! $order) {
echo 'No order object!';
} else if ($order->has_status( 'failed' ) {
echo 'Order failed for some reason.';
} else {
echo $order->get_total();
}
If you don't have the $order object, you can get it from the order id:
$order = wc_get_order( $order_id );
$order->get_total();
If you don't have the order id OR the $order object available, then we need more information to be able to help.
