i have post object tht needs to be set or updated based on the text i m using update_field for the same but it doesn’t update the selected value for the post object in the post
$allposts= get_posts(array('post_type' => 'genres', 'numberposts' => -1));
foreach ( $allposts as $post ) : setup_postdata($post);
What field type is ‘genrelist’?
If it is a post_object or relationship field, you can’t save “MYSTERY” as the value, you instead need to save a numeric value of the post’s ID.
If the field type is a text based field, your code should work.
If the field ‘genrelist’ is a new field and has not yet been saved on the fields, please read over the docs below to understand why you need to use the field_key instead of the field name
