I have a custom post type and I need one of its custom fields to automatically have the post id of that post. How can I do this?

I’m not sure the field type, but you can populate a select field like this. Place the following in your functions.php file.

function acf_load_field_choices( $field ) {

  	// Create an empty array
	$field['choices'] = array();

	// Populate field with the current post id
	$field['choices'][0] = get_the_ID();

  	// Return the result
	return $field;

}

add_filter('acf/load_field/name=test', 'acf_load_field_choices');
