Laravel - Get Data from Table where clause in other table - laravel

Question

I have this following 2 tables:
Table: Products
+----+---------+-------------+
| id | fn_id | created_at |
+----+---------+-------------+
| 1 | 4 | SOME TIME |
| 2 | 5 | SOME TIME |
| 3 | 6 | SOME TIME |
| 4 | 10 | SOME TIME |
| 5 | 10 | SOME TIME |
+----+---------+-------------+
Table Fn
+----+---------+-------------+
| id | fn_id | created_at |
+----+---------+-------------+
| 1 | 10 | SOME TIME |
| 2 | 11 | SOME TIME |
| 3 | 12 | SOME TIME |
| 4 | 14 | SOME TIME |
+----+---------+-------------+
And a User Input which is giving me a timestamp ($user_timestamp).
Now I need to get all produtcs, where
products.fn_id is 10
fn.fn_id is 10
fn.created == $user_timestamp
The products model has this relation:
public function fn() {
return $this->hasMany('App\FN', 'fn_id', 'fn_id');
}
Now I've tried multiple things like a where query where I want to check if the fn_id on both are "10" and the created_at value of the fn table is equal to $user_timestamp.
However, I wasn't able to do it.
$products = Products::with('fn')->where('fn.fn_id', function ($query) use ($user_timestamp) {
$query->where([['fn_id', 10],['created_at', $user_timestamp]]);
})->get();

Answer 1

You would have to use whereHas to constrain Products based on fn.
$products = Products::with('fn')->whereHas('fn', function($q) use($user_timestamp){
$q->where('fn_id', 10)->where('created_at', $user_timestamp);
})->get();

Answer 2

try this
$id_to_search=10;
$products = Products::with('fn')->where('fbn_id',$id_to_search)->whereHas('fn', function($q) use($user_timestamp,$id_to_search){
$q->where('fn_id', $id_to_search)->where('created_at', $user_timestamp);
})->get();
