  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!
