MySQL PDO has no errors, but not pulling data - mysql

Question

Something funky is going on with my MySQL PDO query.
If I pass in an array of values, it does not.
If I don't pass in the arrays it works.
I know this because I get a PDO error 0000, but when I run
$num_events_months = $result_events_months->rowCount();
it only returns a value if the values are hard-coded into the query.
I'm just not sure what I'm doing wrong?
The following DOES NOT work:
$query_events_months = "SELECT DATE_FORMAT(event_date, '%Y-%m') AS event_month_year, DATE_FORMAT(event_date, '%M') AS event_month_name FROM Events WHERE event_date >= :current_date AND status = :status GROUP BY event_month_year";
$result_events_months = $conn->prepare($query_events_months);
$result_events_months->execute(array(':current_date'=>'2014-10-01',':status'=>'published'));
The following DOES work:
$query_events_months = "SELECT DATE_FORMAT(event_date, '%Y-%m') AS event_month_year, DATE_FORMAT(event_date, '%M') AS event_month_name FROM Events WHERE event_date >= '2014-10-01' AND status = 'published' GROUP BY event_month_year";
$result_events_months = $conn->prepare($query_events_months);
$result_events_months->execute(array(':current_date'=>'2014-10-01',
':status'=>'published'));

PDO ERROR 000 is the value returned when a query executed successfully.
You should only print when it fails, otherwise you should ignore.
In your case something along the lines:
if(!$result_events_months->execute(array(...))){
var_dump($result_events_months->errorInfo()); //not outside of the failure block
}else{
var_dump($result_events_months->fetchAll());
}
