Laravel how to use $request except on nested array - php

Question

Is it possible to use $request->except on a nested array? This is the request data:
[▼
"id" => 1
"products" => array:1 [▼
0 => array:4 [▼
"id" => 1
"name" => "sample product"
"date" => "07/04/2022"
"frequency" => array:1 [ …1]
]
]
]
My goal is to remove some key value pairs e.g. removing id, date and frequency. My desired result would be:
[▼
"id" => 1
"products" => array:1 [▼
0 => array:1 [▼
"name" => "sample product"
]
]
]
What I've tried so far is to use Arr:except function:
$request->products = Arr::except($request->products['0'], ['id', 'date', 'frequency']);
But this should be applied on all items. Let's say I have two item products, the desired result would be:
[▼
"id" => 1
"products" => array:2 [▼
0 => array:1 [▼
"name" => "sample product"
]
1 => array:1 [▼
"name" => "sample product 2"
]
]
]
Need your inputs on what's the best approach for this. Thank you!

Answer 1

Unless I am missing something obvious, could you not just iterate over the products in your $request object?
$filtered = [];
foreach ($request->products as $product) {
$filtered[] = Arr::except($product, ['id', 'date', 'frequency']);
}
dd($filtered);
Resulting in $filtered containing:
^ array:2 [▼
"id" => 1
"products" => array:2 [▼
0 => array:1 [▼
"name" => "sample product"
]
1 => array:1 [▼
"name" => "sample product 2"
]
]
]
Update 1
I can see that the $request except only works on the top level
Not sure what you mean by this as the above principle works for me.
$filtered = [];
foreach ($request->products as $product) {
$filtered[] = Arr::except($product, ['id', 'date', 'frequency']);
}
$request->merge(['products' => $filtered]);
If I supply the above with the following:
{
"id": 1,
"products": [
{
"id": 1,
"name": "sample product",
"date": "07/04/2022",
"frequency": []
},
{
"id": 2,
"name": "sample product 2",
"date": "07/04/2022",
"frequency": []
}
]
}
Then do a dd($request->products); I get:
^ array:2 [▼
0 => array:1 [▼
"name" => "sample product"
]
1 => array:1 [▼
"name" => "sample product 2"
]
]
