我正在使用laravel .i已经打印print_r($data->toArray());，因为它产生了以下数组
Array
(
[id] => 1
[album_name] => asfasfsaf
[album_release_date] => 2017-02-08
[album_produced_by] => safasfasfas
[music_director_name] => fasfasfsafas
[music_singer_name] => fasfas
[album_featured_image] => 3.JPG
[album_description] => sfsa
[created_at] => 2017-02-08 05:39:10
[updated_at] => 2017-02-08 05:39:10
[album_images] => Array
(
[0] => Array
(
[id] => 20
[album_id] => 1
[album_image_name] => 1486549223.JPG
[album_image_description] =>
[created_at] => 2017-02-08 10:20:23
[updated_at] => 2017-02-08 10:20:23
)
[1] => Array
(
[id] => 21
[album_id] => 1
[album_image_name] => dsgsdds
[album_image_description] => sdgsdg
[created_at] => 2017-02-14 00:00:00
[updated_at] => 2017-02-21 00:00:00
)
[2] => Array
(
[id] => 22
[album_id] => 1
[album_image_name] => fasf.jpg
[album_image_description] => safsaf
[created_at] => 2017-02-21 00:00:00
[updated_at] => 2017-02-21 00:00:00
)
)
)
我正在尝试打印输出album_images数据但其返回空
print_r($data->album_images);
print_r($data['album_images']);
如果我打印print_r($data->album_name);其返回结果
都返回空
即使我在返回视图之前已在控制器中打印
$data= Album::where('id', $id)->with('AlbumImages')->first();
echo "<pre>";
print_r($data->toArray());
print_r($data->album_images);
没有结果 任何人都可以帮助我在哪里做错了
控制器
$data= Album::where('id', $id)->with('AlbumImages')->first();

答案 0 :(得分：1)
为什么不首先将$data转换为数组$data = $data->toArray();，然后尝试从中$data['album-images']获取数据。
如果那对您有用，请告诉我。
答案 1 :(得分：0)
我试过这样：
在控制器：
$ data =专辑:: where（＆＃39; id＆＃39;，$ id） - ＆gt; with（＆＃39; AlbumImages＆＃39;） - ＆gt; first（）;
返回View :: make（＆＃39; new＆＃39;，compact（＆＃39; data＆＃39;））;
在视图：
{{的print_r（$用户＆GT; album_images）}}
请尝试这样，让我知道结果。
