Populate a select inside a flexible-field

Hi,
is it possibile to dinamically populate a select field inside a flexible-field, using a repeater field placed inside the option page?
I’ve followed your tutorial and look up to the support forum but cannot manage to find a solution to both my problems: the select field remains empty and I get a “Warning: trim() expects parameter 1 to be string, array given in” just above the empty select (and that’s very strange)

Here is my code:

function makerBot( $field )
{
	$field['choices'] = array();
 
	if(get_field('cta_makerbot', 'option'))
	{
		while(has_sub_field('cta_makerbot', 'option'))
		{
			$value = get_sub_field('class');
			$label = get_sub_field('nicename');
 
			$field['choices'][$value] = $label;
		}
	}
 
    return $field;
}
 
add_filter('acf/load_value/key=field_52f8f9253c9ca', 'makerBot');

thanks for your help!

[quick update post-debug]

this is my array before $field

Array
(
    [choices] => Array
        (
            [home] => Homepage
            [servizi] => Servizi
        )

)

(Results are correct)

Fixed! How? I don’t know. I simply erased/redo everything and it worked 🙂

Bottom line: thanks again for your incredible work with ACF, you’ve completely change the way I design websites and I owe you big time
cheers!
