Query Builder "OR" in dynamic query - symfony

Question

I would like to build a query with clause "OR" and the query receive an array parameter and doesn't know how elements it contains.
The query has to return a list of contents that have the category "1" or "2"(if $categ array contain [1,2]) etc.
Category is a foreign key in the content entity.
My repository:
public function getContentOfSomeCategories($categs)
{
$query = $this->createQueryBuilder('c');
$conditions = [];
foreach($categs as $value){
$conditions[] = 'c.contentCategory = '.$value;
}
$orX = $query->expr()->orX();
foreach ($conditions as $condition) {
$orX->add($condition);
}
$query->add('where', $orX);
I obtain the error message "Too many parameters: the query defines 1 parameters and you bound 2".

Answer 1

From PHP 5.6 onward, you can probably use PHP splat ... to expand an array to arguments.
$query = $this->createQueryBuilder('c');
$expr = $query->expr();
$conditions = [];
$valueNo = 0;
foreach ($categs as $value) {
$conditions[] = $expr->eq('c.contentCategory', 'value'.$valueNo);
$query->setParameter('value'.$valueNo, $value);
$valueNo++;
}
$query->andWhere($expr->orX(...$conditions));
Disclaimer: I've not tested this.
See: https://www.php.net/manual/en/functions.arguments.php
You can also use ... when calling functions to unpack an array or Traversable variable or literal into the argument list:
Edit:
If your query is simple, you could just use orWhere instead.
$query = $this->createQueryBuilder('c');
$expr = $query->expr();
$valueNo = 0;
foreach ($categs as $value) {
$query->orWhere($expr->eq('c.contentCategory', 'value'.$valueNo));
$query->setParameter('value'.$valueNo, $value);
$valueNo++;
}
Edit 2:
You might even want to just use an in clause instead.
$query->where($expr->in('c.contentCategory', ':values'));
$query->setParameter('values', $categs);`

You can achieve this quite easily, below utilises the query builder expression builder:
$queryBuilder = $this->createQueryBuilder('c');
$conditions = [];
$i = 0;
foreach ($categs as $value) {
$i++;
$conditions[] = $queryBuilder->expr()->eq('c.contentCategory', $i);
$queryBuilder->setParameter($i, $value);
}
$queryBuilder->andWhere(
$queryBuilder->expr()->orX()->addMultiple($conditions)
);
If you parameter applies to all then you can just add
$queryBuilder->setParameter();
