试图仅在我的网站上获取非对象的属性'id'

Question

最近，我更新了我的网站，但仅在一个视图中发现了此错误，在我的本地主机上工作正常，我通过FTP上传了它。我快疯了！

[2020-01-30 03:32:39] local.ERROR: Trying to get property 'id' of non-object (View: /home/csinf298/resources/views/addEdit_promotion.blade.php) {"userId":3,"email":"[email protected]","exception":"[object] (ErrorException(code: 0): Trying to get property 'id' of non-object (View: /home/csinf298/resources/views/addEdit_promotion.blade.php) at /home/csinf298/storage/framework/views/a22f101b5a2d4fafaa9530cd13c1077aebc547ce.php:211, ErrorException(code: 0): Trying to get property 'id' of non-object at /home/csinf298/storage/framework/views/a22f101b5a2d4fafaa9530cd13c1077aebc547ce.php:211)

我的刀片

$promotion->id

我也尝试过这个

$ promotion-> ['id']

[2020-01-30 03:58:27] local.ERROR: Parse error: syntax error, unexpected '[', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' (View: /home/csinf298/resources/views/addEdit_promotion.blade.php) {"userId":3,"email":"[email protected]","exception":"[object] (ErrorException(code: 0): Parse error: syntax error, unexpected '[', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' (View: /home/csinf298/resources/views/addEdit_promotion.blade.php) at /home/csinf298/storage/framework/views/a22f101b5a2d4fafaa9530cd13c1077aebc547ce.php:176, Symfony\\Component\\Debug\\Exception\\FatalThrowableError(code: 0): Parse error: syntax error, unexpected '[', expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$' at /home/csinf298/storage/framework/views/a22f101b5a2d4fafaa9530cd13c1077aebc547ce.php:176)

Answer 1

首先，使用以下命令使用$promotion->id 清除缓存。>>

php artisan config:cache
php artisan view:clear
php artisan route:clear
如果仍然出现错误，请使用$promotion->userId，就像我在错误中看到的那样，对象包含userId，而不是id。

Answer 2

您的查询返回的是数组还是对象？如果将其转储出去，您可能会发现它是一个数组，而您所需要的只是数组访问（[]）而不是对象访问（->）。要么试试这个
