Laravel limit查询参数结果

我有一个根据用户输入过滤电影的查询，我需要添加一个

limit

作为查询参数，以限制返回的电影数量，我如何添加这个，我不熟悉编写雄辩的查询

查询

$films = Film
::when($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();

您可以使用

$query->limit（5）

或

$query->take（5）

如果要跳过前5个结果，请使用

$query->skip（5）

如果要添加分页，可以使用

$query->paginate（5）

请参阅更多信息：

您可以同时使用这两种方法

极限方法

$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();

$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();

采用方法

$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();

$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();

你不使用->限制（5）吗？例如bfore->limit（5）->get（）？使用

->take（10）->get…

查看其他问题：感谢url的外观，然后

/films？limit=10

在url中获取limit的值你是说你提供的这个解决方案将返回上述url还是我需要获取其他内容，在执行查询之前，您必须首先在url中获取limit的值，并将其初始化为一个变量。关于如何获取要通过的limit值，有两个选项，请访问本文。谢谢，url是这样的吗？limit=5与url无关。您需要更新url或手动从url获取值
