$this->localdb->createCommand()
->update(
$this->MYTable,
[
'name' => $el['new'],
'data' => $el['data'],
],
[
'userId', $this->user,
'product_id', $this->productId,
'name', $el['old'],
'created', $el['date'],
'category', $el['cat'],
]
);
I tried to use the following command to update a row using multiple where conditions, but it doesn't work for some reason. The documentation doesn't seem to cover this case and doesn't seem to be updated, because the update() method seems to match the updateAll method instead of the update method for some reason (maybe it was updated?). So I was wondering what was the correct way to do this.

You have a syntax error. Try following:
$this->localdb->createCommand()
->update(
$this->MYTable,
[
'name' => $el['new'],
'data' => $el['data'],
],
[
'userId' => $this->user,
'product_id' => $this->productId,
'name' => $el['old'],
'created' => $el['date'],
'category' => $el['cat'],
]
);
