How to add new value in collection laravel?

Question

I have the following loop where I try to add a new value:

 foreach ($pro->sig()->get() as $key => $sig) {
            $sig->val = 2;
        }

When I print the output of $pro->sig() I don't have the new value $sig->val

Answer 1

If you have a collection you can use push or put method.

Example with put:

$collection = collect(['product_id' => 1, 'name' => 'Desk']);

$collection->put('test', 'test');

$collection->all();

The output will be:

['product_id' => 1, 'name' => 'Desk', 'test' => 'test']

Example with push:

$collection = collect([1, 2, 3, 4]);

$collection->push(5);

$collection->all();

Output:

[1, 2, 3, 4, 5]

Answer 2

In my example, I tried like the below

foreach ($user->emails as $key => $email) {
   $email->test = "test";
}
return $user->emails;

It outputs like,

  {
    "id": 76,
    "user_id": 5,
    "additional_email": "test@test.com",
    "test": "test"
  }

Please try like this.

Answer 3

$users = User::find(1);

$user->objectName = " Value ";

that works fine if you just need to push another object in the collection by eloquent.
