Laravel迭代数组并写入带关系的模型

Question

I think about dynamic model creation or updating an model.
Let's assume i have an array like this:

$data = array(
'first_name' => 'Max',
'last_name' => 'Power',
'invoiceAddress.city' => 'Berlin',
'invoiceAddress.country_code' => 'DE',
'user.status_code' => 'invited'
);

Now i would like to iterate that array, and write the data to an model, where the dot notation tells me that i must write to an relation.

Normal code:

$model->first_name = $data['first_name'];
$model->last_name = $data['last_name'];
$model->invoiceAddress->city = $data['invoiceAddress.city'];

and so on.

I would prefer a more dynamic way:

foreach($data as $key => $value){
  $properties = explode('.',$key);
  //Now the difficult part
  $model[$properties[0]][$properties[1]] = $value;
  //Would work for invoiceAddress.city,
  //but not for first_name
}

Here is the problem, that i don't know how many properties the explode will create. Is there a way to solve such problem in a dynamic way?

Answer 1

You could use the Illuminate\Support\Arr helper from Laravel like this:

foreach($data as $key => $value) {
    Arr::set($model, $key, $value);
}

It works because the Arr class uses dot notation to access the properties like:

Arr::get($model, 'invoiceAddress.country_code');

Is equivalent to:

$model['invoiceAddress']['country_code'];

If you prefer to use cleaner helper:

foreach($data as $key => $value) {
    array_set($model, $key, $value);
}
