Use Laravel Collection to get duplicate values

laravel collection->search
laravel collection remove duplicates
laravel add to collection
laravel query builder remove duplicates
laravel collection where like
laravel lazy collection
get data without duplicates laravel
get single value from collection laravel

I don´t want to remove the duplicate values, I want to get the articles_id duplicates and sum their quantity values, for example, this is my collection:

Collection {#306 ▼
  #items: array:3 [▼
    0 => CartLine {#294 ▼
      +quantity: 2
      +article_id: 1728
      +article_name: "TAZA CERAMICA"
    }
    1 => CartLine {#296 ▼
      +parent_line_id: null
      +quantity: 1
      +article_id: 1728
      +article_name: "TAZA CERAMICA"
    }
    2 => CartLine {#298 ▼
      +quantity: 1
      +article_id: 1378
      +article_name: "JARRA CERVEZA ALEMANA"

    }
  ]
}

And I want get this result:

Collection {#306 ▼
  #items: array:3 [▼
    0 => CartLine {#294 ▼
      +quantity: 3 //sum total quantity of the duplicates elements with same article_id
      +article_id: 1728
      +article_name: "TAZA CERAMICA"
    }
    1 => CartLine {#296 ▼
      +parent_line_id: null
      +quantity: 3
      +article_id: 1728
      +article_name: "TAZA CERAMICA"
    }
    2 => CartLine {#298 ▼
      +quantity: 1
      +article_id: 1378
      +article_name: "JARRA CERVEZA ALEMANA"

    }
  ]
}

I want sum the quantities of the duplicate elements and set the quantity property with the sum in these elements.

You could try something like:

$collection->groupBy('article_id')->flatMap(function ($items) {

    $quantity = $items->sum('quantity');

    return $items->map(function ($item) use ($quantity) {

        $item->quantity = $quantity;

        return $item;

    });

});

Obviously, change $collection to be whatever you've called the variable that holds your collection.

Hope this helps!

Removing duplicates from Collection, I have a search controller which is doing the following: LIKE query against Profile model to return Have you tried using the collection unique() method? https://​laravel.com/docs/master/collections#method-unique 'Apple' ]; $collection = collect($arr); $unique_data = $collection->unique()->values()->all();. Duplicate a Laravel collection for usage Posted 4 years ago by djave_co. I'm trying to give a copy of a collection of users to an eloquent model jobs. So I'd

I know this answer was already accepted, but I just found this StackOverflow post when I was searching for the same thing. What I ended up doing was the following.

$users = Users::all();
$usersUnique = $users->unique('id');
$usersDupes = $users->diff($usersUnique);

dd($users, $usersUnique, $usersDupes);

I only needed mine for a one time purpose so I am not sure how performant this would be if you need to use it on production page.

Finding Duplicate Data, I stuck somewhere in code where i want to find duplicate data using laravel 5. Let i have a table users and it have an ip field for ip address which store user ip Please tell me how to convert it into laravel 5 using eloquent. Since collect() is part of the Enumerable contract, you can safely use it to get a Collection instance. concat() The concat method appends the given array or collection values onto the end of the collection:

Another one solution to obtain grouped duplicates:

    $collection = collect([
        [
            'name' => 'aa',
            'value' => 22
        ],
        [
            'name' => 'bb',
            'value' => 22
        ],
        [
            'name' => 'cc',
            'value' => 11
        ],
        [
            'name' => 'bb',
            'value' => 33
        ],
        [
            'name' => 'bb',
            'value' => 33
        ],
        [
            'name' => 'bb',
            'value' => 33
        ],
    ]);

    $groupedByValue = $collection->groupBy('value');

    $dupes = $groupedByValue->filter(function (Collection $groups) {
        return $groups->count() > 1;
    });

Output:

array:2 [▼
  22 => array:2 [▼
    0 => array:2 [▼
      "name" => "aa"
      "value" => 22
    ]
    1 => array:2 [▼
      "name" => "bb"
      "value" => 22
    ]
  ]
  33 => array:3 [▼
    0 => array:2 [▼
      "name" => "bb"
      "value" => 33
    ]
    1 => array:2 [▼
      "name" => "bb"
      "value" => 33
    ]
    2 => array:2 [▼
      "name" => "bb"
      "value" => 33
    ]
  ]
