A Laravel package to get row(s) with the group-wise maximum or minimum.

(This is for Laravel 5+. For Laravel 4.2)

Installation

Execute composer command.

composer require sukohi/group-wise-filter:2.*

In your model, set GroupWiseFilterTrait.

use Sukohi\GroupWiseFilter\GroupWiseFilterTrait;

class Item extends model
{
    use GroupWiseFilterTrait;
}

Now you can call groupMax() and groupMin().

Simplest Way

$column = 'amount';
$group_by = 'area_id';
$items = \App\Item::groupMax($column, $group_by)->get();

with select(), where() and so on..

You should add table name like this.

$items = \App\Item::select(
                'items.id',
                'items.title'
                'items.area_id'
            );

Order by Group

\App\Item::orderByGroup('ASC');
\App\Item::orderByGroup('DESC');

Grouped table and Grouped table

You can use GROUP_TABLE and GROUP_VALUE like this.

	$items = \App\Item::select('GROUP_TABLE.GROUP_VALUE');
