Magento 2 - Get Collection using custom product Ids and also sort them as the same order as product Ids passed

Question

I need to get the collection using custom product Ids but it should sort the collection based on the sequence product Ids given

Here is what I am doing now, but it is not sorting in sequence

$collection->addAttributeToFilter('entity_id', array('in' => $productIdsarray));

Any help would be appreciated

Answer 1

You just need to add order along with your addAttributeToFilter

$collection->addAttributeToFilter('entity_id', array('in' => $productIdsarray ));
$collection->getSelect()->order(new \Zend_Db_Expr("FIELD(e.entity_id, ".implode(",",$productIdsarray).")"));
