Laravel迭代数组并写入带关系的模型

问题描述：

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?

我认为动态模型创建或更新模型。
我假设我有一个这样的数组： p>

  $ data = array（
'first_name'=＆gt;'Max'，
'last_name'=＆gt;'Power'，
'invoiceAddress.city'  =＆gt;'Berlin'，
'invoiceAddress.country_code'=＆gt;'DE'，
'user.status_code'=＆gt;'invite'
）; 
  code>  pre> 
  
 现在我想迭代该数组，并将数据写入模型，其中点符号告诉我必须写入关系。 p> 
 
 
普通代码：   p> 
 
 
  $ model-＆gt; first_name = $ data ['first_name']; 
 $ model-＆gt; last_name = $ data ['last_name']; 
 $ model  - ＆gt; invoiceAddress-＆gt; city = $ data ['invoiceAddress.city']; 
  code>  pre> 
 
 依此类推。 p> 
 
 
我更喜欢更动态的方式： p> 
 
 
  foreach（$ data as $ key =＆gt; $ value）{
 $ properties = explode（'。'，$ key  ）; 
 //现在困难的部分
 $ model [$ properties [0]] [$ properties [1]] = $ value; 
 //适用于发票 Address.city，
 //但不是对于first_name 
} 
  code>  pre> 
 
 这是问题，我不知道爆炸会创建多少属性 。
有没有办法以动态的方式解决这个问题？ p>

答

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);
}
