For each loop continious but doesn't fill array

Question

Problem

Hey, my array $isActiefErr and $naamErr doesn't fill up after I throw an exception, but the foreach loop does continue to validate the values. I know the foreach loop keeps on looping, because the array which should have all the values is filled, but the error array stops after it encounters its first error.

What I have tried:

I've tried to print the array but it only pushes the first error into my array. It then stops validating. This also shows in my error log. I think the problem would be the try/catch, but I simply cannot confirm this, because of my lack of knowledge regarding try/catches.

Question

How can I get the array to push and display all the errors with a try/catch block surrounding it? Or am I simply missing something and isn't the problem related to the try/catch?

This is my code:

$validateOk = 0;
$setVar = new SetVariable();

$teller = 1;
$save = null;
$validateOk = 0;

$con->beginTransaction();
$weg = TypeQuery::create()->find();
$weg->delete();

try {
    foreach ($_POST as $key => $value) {
        if (isEven($teller)) {
            $validateOk += $setVar->nameval($key)
                ->onerror($isActiefErr[]) //errors aren't being pushed into this array, besides the first one.
                ->validator(v::numericVal())
                ->go();
            if ($validateOk == 0) {
                $save->setCode(substr($key, 1));
                $save->setIsActief($value);
                $save->save();
            } else {
                //ROLLBACK/CATCH
                throw new Exception($error);
            }
        } else {
            $validateOk += $setVar->nameval($key)
                ->onerror($naamErr[])
                ->validator(v::alpha('/()éá&.,   '))
                ->go();
            if ($validateOk == 0) {
                $save = new Type();
                $save->setCode(substr($key, 1));
                $save->setNaam($value);
            } else {
                //ROLLBACK/CATCH
                throw new Exception($error);
            }
        }
        $teller += 1;
    }
    $con->commit();
} catch (Exception $e) {
    $error = "Het opslaan is fout gegaan!";
} {
    $con->rollback();
}
