For each loop continious but doesn't fill array - php

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();
}
