ModX PDO SQL returns empty array - pdo

Question

I pretty much copy/pasted this from the ModX RTFM:
$results = $modx->query("SELECT * FROM `saved_jobs` WHERE `job_id` = $job_id AND `user_id` = $user");
if (!is_object($results)) {
return 'No result!';
}
else {
$r = $results->fetchAll(PDO::FETCH_ASSOC);
echo $r;
echo "<br>count " . count($r);
print_r($r);
}
But even though there are no records in the database I still get the 'else' occurring. The line echo "count " . count($r); produces the output: count 0
Does anyone know whats going on and how to fix it?

Answer 1

If your query is successful, you still create an object with your first statement.
take a peek [also from the docs]:
$result = $modx->query("SELECT * FROM modx_users WHERE id='blah'");
echo '<pre>'; var_dump($result); echo '</pre>';
if (!is_object($result)) {
return 'No result!';
}
else {
$row = $result->fetch(PDO::FETCH_ASSOC);
return 'Result:' .print_r($row,true);
}
What you want to do is find out if the object actually contains a result set:
$result = $modx->query("SELECT * FROM modx_users WHERE id='1'");
echo '<pre>'; var_dump($result); echo '</pre>';
if (!is_object($result)) {
return FALSE;
}
if(sizeof($result) > 0){
while($row = $result->fetch(PDO::FETCH_ASSOC)){
echo'Result:' .print_r($row,true);
}
}
so you can either test the size of the $result variable or just run the while loop & test if it has any data as well.
