rwmb_autocomplete_field

This filter changes the settings of an autocomplete field before the field shows the selected values in the admin.

apply_filters( 'rwmb_autocomplete_field', $field, $meta );

It has 2 parameters:

Name	Description
`$field`	Field settings
`$meta`	Array of the selected values

The plugin uses $field['options'] to get the labels of the selected values. If the field gets its options from a remote URL, options is a string (the URL). In that case, use this filter to set options to an array of value => label for the selected values.

A related filter, rwmb_autocomplete_result_label, changes the label of each selected value when options is not an array:

apply_filters( 'rwmb_autocomplete_result_label', $value, $field );

Example

Show the city names for the values that come from a remote URL:

add_filter( 'rwmb_autocomplete_result_label', function ( $value, $field ) {
    if ( 'city' !== $field['id'] ) {
        return $value;
    }
    $city = my_get_city( $value ); // Your function to get the city by its code.
    return $city ? $city['name'] : $value;
}, 10, 2 );
