How to get all tags for a node

💻 Development

Hello!

I want to get all tags from a node programmatically.

What is the correct way to do this?

There is ISystemTagObjectMapper::getTagIdsForObjects. Do i have to use this function or is there a better way to get the tags for a node?

Thank you very much!

Hello!

So here is my solution to the problem.
Using ISystemTagObjectMapper::getTagIdsForObjects didn’t work for me so i wrote my on function using the IDBConnection interface.

Here it is:

	public function getSystemTagsForNode(int $nodeId): array {
		$query = $this->connection->getQueryBuilder();
		$query->select("*")
			->from(SystemTagObjectMapper::RELATION_TABLE, "m")
			->innerJoin("m", SystemTagManager::TAG_TABLE, "s", "m.systemtagid = s.id")
			->where($query->expr()->eq('m.objectid', $query->createParameter('oId')))
			->setParameter('oId', $nodeId);

		$systemTagIds = [];
		$result = $query->execute();
		while ($row = $result->fetch()) {
			$systemTag = $this->createSystemTagFromRow($row);
			array_push($systemTagIds, $systemTag);
		}
		$result->closeCursor();

		return $systemTagIds;
	}
