laravel5一对多的create问题

array:7 [▼

"_token" => "Y9szFJQYRcmHpyBB1McOE9tbUoZmshmJHzfV1hMG"

"title" => "1"

"image" => "2"

"itemimages" => array:2 [▼

0 => array:1 [▼

  "image" => "/editor/php/../attached/image/20151203/20151203071049_60053.png"

1 => array:1 [▼

  "image" => "/editor/php/../attached/image/20151203/20151203071049_32261.png"

"category_id" => "4"

"content" => "3"

"text" => "3"

一个表单传递过来一个商品的信息，并且这个商品

$data=$request->all();

    $data['text']=mb_substr($data['content'],0,64);

    $save=Item::create($data);

商品创建成功，然后需要往图片库里加图片$data['itemimages'],

$save->itemimages()->save($data['itemimages']);//报错

$save->itemimages()->saveMany($data['itemimages']);//报错

$save->itemimages()->create($data['itemimages']);//item_id有值，image为空

后来尝试格式换一下

"itemimages" => array:1 [▼

  "image" => "/editor/php/../attached/image/20151203/20151203071049_60053.png"

]



$save->itemimages()->create($data['itemimages']);//成功

那么多张图片怎么办

Item已经定义

public function itemimages(){

return $this->hasMany("App\Itemimage");

}
