I have a custom post type that I'm trying to retreive values from. The first custom field is a standard dropdown menu, and the second is a multi-select dropdown menu.
The first dropdown menu I can use the following for, which retrieves the value correctly:
simple_fields_get_post_value(get_the_id(),array(1, 2), true);
However I get the below error when I try and use the code to retrive the multi-select value:
Illegal offset type in simple-fields\functions.php on line 83
simple_fields_get_post_value(get_the_id(),array(1, 10), true);
What am I doing wrong?
