The function get_the_author_meta(‘ID’) will return the ID of the author for the current post. That means this line should work. get_avatar( get_the_author_meta( ‘ID’ ), 120); This will not work get_avatar( get_the_author_meta( ‘4’ ), 120); Because you are trying to get a property named ‘4’ inside the user object and that property doesn’t exist. If you … Read more
Dunno if you looked at add_user_meta, but it takes an optional fourth parameter. function add_user_meta( $user_id, $meta_key, $meta_value, $unique = false ) Send “true” to the $unique value and it won’t insert it twice. https://developer.wordpress.org/reference/functions/add_user_meta/
Fastest way would be something like this: $fruit_id = get_user_meta($user_id, ‘fruit’, true); //returns 1 $display_fruit = some_fruits($fruit_id); //will return ‘Apple’

$wpdb->get_results() returns an array on success, so you can’t simply echo $result;. Instead, you can use foreach to loop through the results and display whatever the data that you want to display: $results = $wpdb->get_results( $q ); foreach ( $results as $row ) { echo $row->meta_value . ‘<br />’; } But I can see that … Read more
Short answer to “Which property am I supposed to use“: Use first_name and last_name. Longer answer: The properties first_name, user_firstname, last_name and user_lastname are defined in the WP_User class, and despite the different names (i.e. one with user_ and the other without that prefix): Both first_name and user_firstname use the value of the first_name meta. … Read more

Edit: to clarify, the answer to How can I merge them together for results? Is that you really can’t, not without a lot of custom SQL and using filters.
