i'm using EntityFieldQuery to retrieve some nodes according to some conditions.

foreach (array("important", "normal") as $type) {
  $query = new EntityFieldQuery();
  $query->entityCondition("entity_type", "node")
    ->entityCondition("bundle", "Announce")
    ->fieldCondition("field_ann_cat", "value", array($nid))
    ->fieldCondition("field_ann_type", "value", array($type));
  $result = $query->execute();
  var_dump($result);
  // Some actions
}

The first time it loops, i have my announces marked as "important" (field_ann_type). The second time it loops, i dont have any announces marked as "normal".

I've tried to intervert them, and when i have array("normal", "important") instead of array("important", "normal") in my foreach, i can see my announces marked as "normal", but not my announces marked as "important".

Does anyone knows why? Thanks.

There's no need to use a loop, if you pass an array as the 3rd argument to fieldCondition it will create an IN() statement for you in MySQL.

As far as I can tell your query should just look like this:

$types = array("important", "normal");
$query = new EntityFieldQuery();
$query->entityCondition("entity_type", "node")
  ->entityCondition("bundle", "Announce")
  ->fieldCondition("field_ann_cat", "value", $nid)
  ->fieldCondition("field_ann_type", "value", $types);

$result = $query->execute();

If you want to go one step further and ensure the IN operator is used you can pass it (but it's not necessary):

$query->fieldCondition("field_ann_type", "value", $types, 'IN');

As NenadP has already mentioned, there's no need to explicitly use an array as the 3rd argument unless you're putting the value in inline, e.g.

$query->fieldCondition("field_ann_type", "value", array("important", "normal"));`
  • In fact, i wanted them to be in multiple array (what was done in some actions commentary). By the way, i found another way to solve my problem. Thanks for the answer, i'll take a look at this later. – Lght Sep 6 '12 at 15:33
  • Gotcha. It's quite expensive to put db queries in a loop, if you can get away with grabbing all of the data in one go then using PHP to build up the local structures it's probably advisable – Clive Sep 6 '12 at 15:57

It may be because you are doing this:

->fieldCondition("field_ann_type", "value", array($type));

try just check it against $type like this:

->fieldCondition("field_ann_type", "value", $type);
  • Thinking about it there's actually no difference at all between those 2 methods...if you wrap the argument in an array the SQL statement will just convert to an IN() which is equally valid and will produce exactly the same results. – Clive Sep 6 '12 at 17:34
