How do i use $inc using the object document mapper.
db.products.update(
{ sku: "abc123" },
{ $inc: { quantity: -2, "metrics.orders": 1 } }
)
Have you tried with something like
db.products.update(
[ sku => "abc123" ],
[ "$inc" => [ quantity => -2, "metrics.orders" => 1 ] ]
)or using array() instead of [] if using older PHP?
hmm, i am using the object document mapper. when i use ::update it says, function cannot be found
In the end i stick to the below. Any difference from using $inc? performance wise?
public function _incrementPageviews($id){
$page = Page::findById( $id );
$page->pageViews += 1;
$page->save();
}
