Laravel limit query param results

Question

i have a query which filters films based upon the input by the user, i am needing to add a limit as a query parameter so it limits the amount of films that are returned, how do i add this in, i am new to writing eloquent queries.

query

$films = Film
::when($request->input('first'), function ($query, $first) {
    $query->whereHas('options', function ($query) use ($first) {
        $query->where('first', $main);
    });
})
->when($request->input('second'), function ($query, $second) {
    $query->whereHas('options', function ($query) use ($second) {
        $query->where('second', $second );
    });
})
->when($request->input('age'), function ($query, $age) {
    $query->whereHas('ageRatings', function ($query) use ($age) {
        $query->where('age', $age);
    });
})
->when($request->input('country'), function ($query, $country) {
    $query->whereHas('locations', function ($query) use ($country) {
        $query->where('country', $country);
    });
})
->when($request->input('city'), function ($query, $city) {
    $query->whereHas('locations', function ($query) use ($city) {
        $query->where('city', $city);
    });
})
->get();

Use `->take(10) -> get...` See other question: https://stackoverflow.com/questions/35643192/laravel-eloquent-limit-and-offset — Bert Maurau, Jan 21 '20 at 15:06

You can use $query->limit(5) or $query->take(5).

If you want to skip the first 5 results, use $query->skip(5)

If you want to add pagination, you can use $query->paginate(5)

thanks will the url look like this then `/films?limit=5` – lilnoobcoder Jan 21 '20 at 15:17
This has nothing to do with urls. You need to update your url or get the value from the url manually – Patrick Schocke Jan 21 '20 at 15:35

You can use both of these method

the Limit method

$limit = 10;
$films = Film
::when($request->input('first'), function ($query, $first) {
    $query->whereHas('options', function ($query) use ($first) {
        $query->where('first', $first);
    });
})
->when($request->input('second'), function ($query, $second) {
    $query->whereHas(‘options', function ($query) use ($second) {
        $query->where('second', $second);
    });
})
->when($request->input('age'), function ($query, $age) {
    $query->whereHas('ageRatings', function ($query) use ($age) {
        $query->where('age', $age);
    });
})
->when($request->input('country'), function ($query, $country) {
    $query->whereHas('locations', function ($query) use ($country) {
        $query->where('country', $country);
    });
})
->when($request->input('city'), function ($query, $city) {
    $query->whereHas('locations', function ($query) use ($city) {
        $query->where('city', $city);
    });
})
->limit($limit)
->get();

the Take method

$limit = 10;
    $films = Film
    ::when($request->input('first'), function ($query, $first) {
        $query->whereHas('options', function ($query) use ($first) {
            $query->where('first', $first);
        });
    })
    ->when($request->input('second'), function ($query, $second) {
        $query->whereHas('options', function ($query) use ($second) {
            $query->where('second', $second);
        });
    })
    ->when($request->input('age'), function ($query, $age) {
        $query->whereHas('ageRatings', function ($query) use ($age) {
            $query->where('age', $age);
        });
    })
    ->when($request->input('country'), function ($query, $country) {
        $query->whereHas('locations', function ($query) use ($country) {
            $query->where('country', $country);
        });
    })
    ->when($request->input('city'), function ($query, $city) {
        $query->whereHas('locations', function ($query) use ($city) {
            $query->where('city', $city);
        });
    })
    ->take($limit)
    ->get();

`get the value of limit in url` do you mean this solution you provided will return the above url or am i needing to get something else — lilnoobcoder, Jan 21 '20 at 15:29
no it does not, you have to get first the value of limit in your url and initialize it to a variable before you execute the query — Qonvex620, Jan 21 '20 at 15:33
btw there are two options on how you can get the value of limit you want to pass, just visit this article https://www.5balloons.info/how-to-get-url-parameters-into-controller-laravel/ — Qonvex620, Jan 21 '20 at 15:38
