set selected value(s) for select fields

Using load_field I can set the value for a text field and other fields, but I’m having problems trying to set the value for a select2 field (single & multiple) after they’ve had an array of values already added.

I’ve tried a whole myriad of combinations in both load_field and load_value but can’t get anything to work.

Essentially I’m after something like this:

First, this runs to load a list of countries & languages into the fields – this works fine:

add_filter('acf/load_field', 'load_country_language_field', 10);
function load_country_language_field( $field ) {
	// languages & countries are loaded into the fields
}

Then I want to run something like this code to set the default single value for a country and the default values for languages. This doesn’t work:

add_filter('acf/load_field', 'load_default_values', 20);
function load_default_values( $field ) {
	// put in a single country
	if ( $field['key'] == 'field_5eca5ca92515d' ) {
		$field['value'] = 'France';
		return $field;
	}
	// put in multiple languages
	if ( $field['key'] == 'field_5eca5ca925318' ) {
		$field['value'] = 'English';
		$field['value'] = 'German';
		$field['value'] = 'Italian';
		return $field;
	}
}

Any help appreciated!

A select field stores an array and your values always need to be arrays

$field['value'] = array('France');
// or 
$field['value'] = array('English', 'German', 'Italian');

ensure that you are using the value and not the label.
