okay so I got the values to populate using the code below
function populate_phone($field) {
global $wpdb; //use wp database
$field['value'] = 'N/A'; //default value
$current_user_id = get_current_user_id(); //get logged in user's id
$wp_custom_user_info = $wpdb->get_results("
SELECT * FROM custom_table
WHERE wp_user=" . $current_user_id
);
$field['value'] = $wp_custom_user_info[0]->phone_numbers;
return $field;
}
add_filter('acf/load_field/name=phone', 'populate_phone');
My other question still stands: How do I update that value after pressing “Save/Update” button?
