I think I’m having this problem as well. It’s really wierd.
I’m building a custom WooCommerce-action that does a bunch of stuff for the given order. I initiate the action, by adding this to the functions.php-file:
function custom_add_order_action( $actions ){
global $theorder;
$actions['custom_thing'] = 'My own custom action';
return $actions;
}
add_action( 'woocommerce_order_actions', 'custom_add_order_action' );
add_action( 'woocommerce_order_action_custom_thing', 'custom_action_content' );
function custom_action_content( $order ){
$my_class = new WcActionCustomActionClass( $order );
}
… and inside WcActionCustomActionClass a bunch of things happen.
One of which should be to update the ACF-fields for the WooCommerce order. Let’s say that the order_id is 12345.
Regardless of what I do, then I can’t get it to update _any_ of the fields, when I run update_field() inside my class, _unless_ if I write die()' afterwards(?!).
So if I do this:
update_field( 'test', 'some value', 12345 );
and run the action, then the value of the test-field hasn’t changed.
But if do this:
update_field( 'test', 'some value', 12345 );
die();
… and then check it in another browser-window, then the value _does_ change. Really wierd!

### Solution attempts
**1. New field**
I tried creating a new field and trying to update that. Exactly the same bug as described above.
**2. Updating the field elsewhere**
I tried updating the field in the init-hook, ensuring that my code actually works:
function test_init(){
update_field( 'test', 'another test value', 12345 );
}
add_action( 'init', 'test_init' );
This updates the field (as it should).
**3. Updating the field before my class is initialized**
I tried changing my code, so it looks like this instead:
...
function custom_action_content( $order ){
update_field( 'test', 'another another test value', 12345 );
$my_class = new WcActionCustomActionClass( $order );
}
**4. Using the field_key**
I tried using the field key, like this:
...
function custom_action_content( $order ){
update_field( 'field_603f667437ba9', 'another another another test value', 12345 );
$my_class = new WcActionCustomActionClass( $order );
}
… Same thing. No change.
And again. If I do this:
...
function custom_action_content( $order ){
update_field( 'field_603f667437ba9', 'another another another test value', 12345 );
die();
$my_class = new WcActionCustomActionClass( $order );
}
… and open the order in a new window, then the value updates(?!). Omg…
**5. get_the_object**
Inside my class, I tried getting the field object, ensuring that it was accessible. So I did this:
$field = get_field_object( 'field_603f667437ba9' );
vardump( $field );
die();
and it returns an array of the field:
array (
"ID" => 48617
"key" => "field_603f667437ba9"
"label" => "Test"
"name" => "test"
"prefix" => "acf"
"type" => "text"
...
So it _is_ accessible! Hmm…
**6. Moving the function up to fire earlier**
I figured, that maybe something ‘got in the way’ of the ACF-function firing, so by moving it up to be the first thing that runs during that action, then maybe that could make a change.
… But it was the same result: No change, unless I made it die() just after.
**7. Moving the function, making it fire later**
So that means doing this:
...
function custom_action_content( $order ){
$my_class = new WcActionCustomActionClass( $order );
update_field( 'field_603f667437ba9', 'another another another test value', 12345 );
}
… Same thing. Doesn’t change, unless I write die(); after.
**8. Clear cache and restart Apache/Nginx**
Didn’t change anything.
**9. Try using update_post_meta() instead**
Same result.
This doesn’t change anything:
update_post_meta( 12345, 'test', 'Another another another... value' );
This make the value change:
update_post_meta( 12345, 'test', 'Another another another... value' );
die();
