I have started work with lithium framework + mongoDB recently. I want to do a really simple query which contains multiple or statements. I have articles in the DB with publish_up and publish_down fields. I want to fetch only those records/documents which pulbis_down field is highert than now OR null AND publish_up field lower than now OR null.
$items = $article::find('all', array(
'conditions' => array(
'$or' => array(
'$gt' => array('publish_down', $mongoDateNow),
'publish_down' => $mongDateNull
),
'$or' => array(
'$lt' => array('publish_up', $mongoDateNow),
'publish_up' => $mongDateNull
),
)
));
Of course this snippet is wrong hence the second or statement overwrites the first one (because the same array key). I tried to wrap them into an individual array but gives error. Any idea?
This query will fetch articles with (publish_down > now OR publish_down = null) AND (publish_up < now OR publish_up = null)
$items = Articles::find('all', array(
'conditions' => array(
'$or' => array(
array('publish_down' => array('$gt' => $mongoDateNow)),
array('publish_down' => null)
),
'$or' => array(
array('publish_up' => array('$lt' => $mongoDateNow)),
array('publish_up' => null)
),
)
));
I don't know about lithium but in PHP you can use multiple $OR as below
$items = $article::find('all', array(
'conditions' => array(
'$or' => array(
array(
'$gt' => array('publish_down', $mongoDateNow),
'publish_down' => $mongDateNull
),
array(
'$lt' => array('publish_up', $mongoDateNow),
'publish_up' => $mongDateNull
)
),
)
));
I think the correct answer is:
'$and' => array(
array(
'$or'=>array(
array('publish_up' => null),
array('publish_up' => array('$lt' => $mongoDateNow))
)
),
array(
'$or'=>array(
array('publish_down' => null),
array('publish_down' => array('$gt' => $mongoDateNow))
)
)
)
