Question

How can I upsert (update if not added) two fields at the same time?
It worked for a single field, but it doesn’t work for two anymore.

Am I doing something wrong?:

$db->url->update(   
      array("url" => $linkurlcache),
      array('$set' => array('url' => $linkurlcache, 'pos' => $rand_num)),
      array("upsert" => true),
      array("multi" => true)
);

Answer 1

I really hate having to answer my own question. I would have deleted it but I couldn’t find a solution on any website.

Anyhow, the array("multi" => true) made a lot of sense considering we are calling the update function, but it’s wrong.

The correct solution is without it!
Just:

$db->url->update(   
      array("field1" => $field1),
      array('$set' => array('field1' => $field1, 'field2' => $field2)),
      array("upsert" => true)
);

Because upsert actually makes an insert (if the query doesn’t match).
