Product Search using geolocation of shops - laravel

Question

I am new to Laravel and I am trying to search for product using nearby shops
Here is my code
Shop::selectRaw(" id ,
( 6371 * acos( cos( radians(?) ) *
cos( radians( lat ) )
* cos( radians( lng ) - radians(?)
) + sin( radians(?) ) *
sin( radians( lat ) ) )
) AS distance", [$latitude, $longitude, $latitude])
->having("distance", "<", $radius)
->orderBy("distance",'asc')->products()->where('name', 'LIKE', '%' . $keyword . '%')->get();
But I am getting this error message:
"message": "Call to undefined method
Illuminate\Database\Eloquent\Builder::products()"
Note: The Relationship between shop and product is working in my other functions

Answer 1

I am really confused, why are you using products() after orderBy and all the other clauses ?
If you are trying to get products from a shop, you do not have to do products(), you have to use Product::...., but if you want to get shops related to products you have to use whereHas('products', ....), read more about it here.
Your code should be like this:
$shops = Shop::selectRaw(
"id, (6371 * acos(
cos(radians(?)) * cos(radians(lat)) * cos(radians(lng) - radians(?)) + sin(radians(?)) * sin(radians(lat))
)) AS distance",
[$latitude, $longitude, $latitude])
->having("distance", "<", $radius)
->orderBy("distance",'asc')
->whereHas('products', function ($query) use ($keyword) {
return $query->where('name', 'LIKE', '%' . $keyword . '%');
})
->with('products')
->get();
That code will give you shops, you can then do $shops->products.
But if you want directly to get the products you have to use the Product model:
$products = Product::where('name', 'LIKE', '%' . $keyword . '%')
->whereHas('shops', function ($query) use ($latitude, $longitude, $latitude, $radius) {
return $query->selectRaw(
"id, (6371 * acos(
cos(radians(?)) * cos(radians(lat)) * cos(radians(lng) - radians(?)) + sin(radians(?)) * sin(radians(lat))
)) AS distance",
[$latitude, $longitude, $latitude]
)
->having("distance", "<", $radius)
->orderBy("distance",'asc');
})
->get();
