Questions regarding 3rd party plugins are considered off-topic here so you’lle need to dig into the plugins documentation or use its support forum to get an exact answer for you question.


I would recommend you to var_dump() all of the post’s meta to see, if the data is actually saved with the wiki_test_select key or has the plugin added some sort of prefix / suffix to it or used some other structure to store the data. If so, update your code accordingly.

// Using empty key returns all meta fields
var_dump( get_post_meta( get_the_ID(), '', true ) );
