Laravel Carbon return me 0 results

问题

I need to grab this month data for user in database so I write:

 dd($user->products->where('paid',1)->where('created_at','>=', Carbon::now()->startOfMonth()->toDateString())->all());

and I got 0 results...

When I try Carbon::now()->subMonth() its works good but return me last 30 days ...

How I can solve this? How to get only this month data ?

回答1:

->toDateString() is causing the query to look for a string value, and not a date. There's two ways to solve this:

(...)->where('created_at', '>=', Carbon::now()->startOfMonth())
// OR
(...)->whereDate('created_at', '>=', Carbon::now()->startOfMonth()->toDateString())

If you just use a Carbon variable, Laravel knows to check for date logic. Alternatively, if you're using a string, you can override the where logic to treat it as a date by using ->whereDate()
