This module allows you to populate a list field's options with the results of calling a custom function.
Once enabled, in the Field UI, add a new list (ex: List (text)). You will now see a box to enter a value for "Allowed values function". This should be a function name only (no parenthesis), which returns an associative array of values.
For example, on the Configure field screen:
Allowed values function: my_module_test
Then, in your module your function should look like so, including the expected arguments:
function my_module_test($field, $instance, $entity_type, $entity = NULL, $cacheable = FALSE) {
return ['a' => 'Apple', 'ban' => 'Banana'];
}
