Medoo PHP db framework - select join - php

Question

Using Medoo PHP database framework and trying to make a join
$users = $db->select(
'users',
[
'[>] tournaments_users' =>
[
'tournaments_users.user_id' => 'users.uid'
]
], [
'users.uid',
'users.name',
'users.modifier',
'users.handicap',
'tournaments_users.tournament_id'
], [
'tournaments_users.tournament_id' => 1
'ORDER' => 'users.username ASC'
]
);
foreach( $users as $u) {
echo $u['name'].'<br>';
}
The selection results in an invalid argument supplied for foreach().
Removing 'tournaments_users.tournament_id' from the column- and where-section makes the query work, but does not show the correct data.
Why is the query invalid?

Answer 1

Changing the join-selection to
'[>]tournaments_users' =>
[
'uid' => 'user_id'
]
solved the issue with invalid argument.

Answer 2

Concatenation of logical expressions using AND/OR in join clause is currently not supported by the medoo library (medoo 0.9.6.2). You can only use the query($query) method given by medoo to directly execute sql queries. For your example the query looks like this:
$data = $db->query("SELECT u.user_id, s.shirt_id FROM `cvs_users` u
LEFT JOIN `shirts` s
ON user_id = shirt_owner_id AND shirt_being_worn = 1
WHERE user_id = 1")->fetchAll();
Note the call to fetchAll() at the end to get the queried data. I ran into the same problem and debugging the medoo.php code revealed that AND/OR conditions are only considered within where clause. Maybe they'll put this feature in a future update.
