Get option labels without post/user ID

Hi!

I’m about to built a frontend navigation showing all possible values of a <select> field I added to the user profile page via ACF.

Now I’m looking for a way to get the field’s option labels by their values, f.e.:
Field name: ‘country’
Option 1 name: ‘fr’,
Option 1 label: ‘France’

if want to get ‘France’ by ‘fr’.

get_field_object( 'country' ) is returning null since it’s awaiting a post / user ID. But since I’m displaying the nav outside of a post / the loop there is no ID I can query with.

Any ideas?

get_field_object requires the field key if you are not referencing a saved value. The field key looks something like: field_53beaa2f69615

In the Edit Field Group screen:
Screen Options (window shade) > Show Field Key: Yes

One you have it:

$field = get_field_object($field_key);
echo $field['choices']['fr'];

foreach( $field['choices'] as $name => $label ) { ... }

Wouldn’t that mean hard coding these field keys into my code?

In the meantime I ended up querying the database like this:

function get_field_label( $field, $value ) {
    global $wpdb;

    $label = '';
    $field = $wpdb->get_col( $wpdb->prepare( "
        SELECT post_content FROM {$wpdb->posts}
        WHERE post_excerpt = '%s' 
        AND post_type = 'acf-field'
    ", $field ) );

    if( $field ) {
        $options = unserialize( $field[0] );
        $choices = $options['choices'];
        $label = $choices[$value];
    }

    return $label;   
}
