Dynamically set the value of a field

How can I set the value of an ACF, dependent upon the woocommerce product type?

I have this currently:

function whatis_single_product_type( $field ) {
	$field['value'] = __('initialize', 'txtdomain');
	global $post;
    if( function_exists('get_product') ){
    	$product = get_product( $post->ID );
        if( $product->is_type( 'variable' ) ){
        	$field['value'] = __('variable', 'txtdomain'); 
        } elseif( $product->is_type( 'simple' ) ){
                    $field['value'] = __('simple', 'txtdomain'); 
        }
    }    
	return $field;
}
add_filter( 'acf/load_field/name=product_type_set', whatis_single_product_type );

Although this seems to work – saving the text, either ‘variable’ or ‘simple’ to the acf product_type_set (otherwise it stays set to ‘initialize’) – does anyone have a better way?

$field['value'] = $product->get_type();

So I’ve changed it to:

/* sets the acf to product type text */
add_filter('acf/load_field/name=product_type', function($field) {
	global $post;
	$field['value'] = get_product( $post->ID )->get_type();
	return $field;
 });

… which works, but I get an error (There has been a critical error on this website) when attempting to edit the field group for the acf. What can I do to avoid that (other than temporarily removing the filter above)?

Use acf/prepare_field instead

That did the trick – thank you so much!
