Laravel how to auto get array id - php

Question

I know the title isn't that understanding but I will try to explain here my problem.
So I have a form that auto generates input fields by jquery and I'm trying to store that data in the db
the blade:
<div>
<input type="text" placeholder="ID" name="myproduct[]"/>
<input type="text" placeholder="Șansa" name="mychance[]"/>
Delete
</div>
My Controller:
class SomeController extends BaseController {
public function someMethod(Request $request) {
...
$items = '{"'.$request->myproduct[0].'":"'.$request->mychance[0].'", "'.$request->myproduct[1].'":"'.$request->mychance[1].'"}';
$case = Cases::create([
'items' => $items
]);
$case->save();
...
}
}
It is kinda working but I want to know how to get all data in $items without creating new variables like $variable[0], $variable[1],2 ,3 for every input I generate

Answer 1

If you can guarantee that you always have the same amount of products and choices you can use array_combine
$myproduct = [1,2,3];
$mychance = ['test1', 'test2', 'test3'];
$items = array_combine($myproduct, $mychance);
// result: [1 => "test1", 2 => "test2", 3 => "test3"]
// encode it to a string with json_encode
// result: "{"1":"test1","2":"test2","3":"test3"}"
$case = Cases::create(['items' => json_encode($items)]);
Additionaly you can cast your items column to an array
In your Cases model add
protected $casts = [
'items' => 'array',
];
Laravel will then automatically serialize it when storing and deserialize it when accessing giving you an array.
then you could just do
$myproduct = [1,2,3];
$mychance = ['test1', 'test2', 'test3'];
$case = Cases::create(['items' => array_combine($myproduct, $mychance)]);
Array & JSON Casting
The array cast type is particularly useful when working with columns
that are stored as serialized JSON. For example, if your database has
a JSON or TEXT field type that contains serialized JSON, adding the
array cast to that attribute will automatically deserialize the
attribute to a PHP array when you access it on your Eloquent model

You maybe want to do this:
class SomeController extends BaseController {
public function someMethod(Request $request) {
...
$items = [];
foreach($request->myproduct as $i => $myProductSingle) {
$items[$myProductSingle] = $request->mychance[$i];
}
$case = Cases::create([
'items' => json_encode($items)
]);
$case->save();
...
}
}

Hope it helps..
$items = [];
foreach($request->myproduct as $key => $myProduct) {
$items[$myProduct] = $request->mychance[$key];
}
