“尝试获取非对象的属性”错误控制器
“尝试获取非对象的属性”错误控制器
提问于 2018-10-09 03:37:43
如何解决(试图获取非对象的属性)错误，但相同的函数在另一个函数中运行良好
这个控制器的错误之处在于，当更新顺序“尝试获取非对象的属性”时，我总是得到这个错误，(请注意，我正在使用相同的函数来存储，它工作得很好。
我的数据库中有4个表(user_type_id、users、products和orders，orders表包含4列(id、product_id、user_id和qty)，user_id和product_id =用户和产品表的外键。
我也想要一些我不知道如何正确书写的东西，我想当一个客户删除一个订单时，它只有一个订单(数量= 1)，被永久删除，如果他输入了相同的数量，也被永久删除，因为当我测试这个功能时，我发现它一直在删除，直到-1 -2 -3等。
我想如果产品数量是0，隐藏所有用户的产品，除了管理员和卖家谁出售它，或至少隐藏所有的添加到购物车按钮，或用死按钮取代它与缺货而不是添加到购物车，如果用户已经订购了此产品的一部分，他不能更新数量，但可以取消它，然后它将被添加到产品。
我希望如果有人告诉我如何使用注释跨度，因为我也不知道怎么做:D谢谢

this line $product->inv = $product->inv - $order->qty; (it works in store)

$product->save();
return redirect('/myorders');

Route::get('/myorders', 'OrderController@myorders');
Route::get('/add_order', 'OrderController@buy');
Route::get('/add_order/{id}', 'OrderController@store');

Route::get('/update_order/{id}', 'OrderController@update');

Route::get('/delete_order/{id}', 'OrderController@destroy');这是我的观点，我正在使用它
