Real dynamic DQL with doctrine in symfony 3.4 - symfony

Question

I'm trying to achieve a dynamic query with DQL in doctrine. I've checked several post about this subject but all the solutions are static. I want to achieve somethin like this:
$qb->where(
$qb->expr()->orX(
$qb->expr()->like('e.cliente', ':cliente_tag'),
$qb->expr()->like('e.cliente', ':cliente_tag2'),
$qb->expr()->like('e.cliente', ':cliente_tag3')
),
$qb->expr()->orX(
$qb->expr()->like('e.apoderado', ':apoderado_tag'),
$qb->expr()->like('e.apoderado', ':apoderado_tag2'),
$qb->expr()->like('e.apoderado', ':apoderado_tag3')
)
);
but inside a loop like this:
foreach ($options['camposTexto'] as $i => $campoTexto) {
switch ($campoTexto['appliedTo']) {
case 'apoderado': {
$exp = [];
foreach ($campoTexto['tags'] as $tag) {
$exp[] = $qb->expr()->like('e.apoderado', ':apoderado_tag' . $i);
$parameters['apoderado_tag' . $i] = '%' . $tag . '%';
}
if ($isFirst) {
$isFirst = false;
$qb->where($qb->expr()->orX($exp));
} else {
$qb->andWhere($qb->expr()->orX($exp));
}
break;
}
case 'cliente': {
$exp = [];
foreach ($campoTexto['tags'] as $tag) {
$expresiones[] = $qb->expr()->like('e.cliente', ':cliente_tag' . $i);
$parameters['cliente_tag' . $i] = '%' . $tag . '%';
}
if ($isFirst) {
$isFirst = false;
$qb->where($qb->expr()->orX($exp));
} else {
$qb->andWhere($qb->expr()->orX($exp));
}
break;
}
}
}
tags is an array of strings. As you see I passed the array of expresions but doctrine throws me an Exception.
So far so now I have not found any solution to my problem.
Any Idea?
Thanks in advance!

Answer 1

Looking at this post I figured out the solution. It would be something like this:
case 'apoderado': {
$orX = $qb->expr()->orX();
foreach ($campoTexto['tags'] as $y => $tag) {
$orX->add($qb->expr()->like('e.apoderado', $qb->expr()->literal('%' . $tag . '%'))); //<= with literal because I can't set the parameters later in the qb
}
$expresiones[] = $orX;
break;
}
after all the case/break
$andX = $qb->expr()->andX();
$qb->where($andX->addMultiple($expresiones));
return $qb->getQuery()->getResult();
