Question

I am making use of dynamic queries in mongoDB, by using them this way:

$query['clicks'] = array('$gt' => 6);
$query['lang'] = "de";

$cursor = $collection->find($query);

The question is pretty simple and straightforward: how can one add ‘OR’ conditionals? for example to have both ‘lang’ to be “de” OR “fr”;

Because right now, Mongo implies that there is an AND between “clicks” and “lang”. So how can i structure clicks > 6 && ( lang == ‘de’ || lang == ‘fr’ )

Answer 1

You can give try as below

$query['clicks'] = array('$gt' => 6);
$query['$or'] = array(array('lang' => 'de'), array('lang' => 'fr'));
$cursor = $collection->find($query);

How to add $in operator

$query['clicks'] = array('$gt' => 6);
$query['$or'] = array(array('lang' => 'de'), array('lang' => 'fr'));
$query['_id'] = array('$in' => array(new mongoId('506d95bc5c73952c14000002'), new mongoId('506d95bc5c73952c14000003')));

$cursor = $collection->find($query);
