A post can have multiple metadata set on it, using the same key. So setting $single to true tells WordPress that you want only the first entry to be returned. Leaving it false will return all the entries in an array. Since you want a list of users, it's better to set just one metadata entry, and save it as an array.

| Aug 3, 2019 at 23:34 | comment | added | Arg Geo | Also I do not get why $single is set to true since I am searching for the user's ID which will not necessarily be the first object in the array. Edit: I read this answer (wordpress.stackexchange.com/a/245505/15801) which explains it but still can't get it... | |
| Aug 3, 2019 at 23:29 | comment | added | Arg Geo | Thank you for the effort put in offering a solution to my problem. I can't try the code at this moment but will do later and let you know. Leaving $single unset was on purpose as I read in wordpress codex it has to be false (as is by default) otherwise the meta_key accepts only one value and replaces it with the latest, if one provided. Something else about $readers = array(); I had the impression, as I read on wordpress documentation that wordpress perceives $readers as an array by default so why declare it? | |
