Comment:

 Hi there

 The documentation for `post__not_in` is pretty clear:

 > An array of post IDs not to retrieve. Note: a string of comma-separated
 IDs will NOT work.

 `array(316,319,321)` is an array of integers, which are post IDs.

 In your example, `array($exclude_string)` is the same as writing `array(
 '316,319,321' )`. This is an array with one item, a string containing a
 comma-separated list of post IDs.

 To make your code work, just use `$query->set( 'post__not_in', array(
 implode( ',', $exclude_string ) ) );`.
