这是我的html代码

因此功能类似于，如果我创建数据，则此后应该将其重定向到索引或视图页面，但是在我的情况下，提交/创建数据后它给了我这个错误，我不知道为什么

View Page

我具有与该页面相同的页面，但具有相同的功能，但事实证明这就是为什么，我想知道为什么，而且我在此处发布的此创建页面在更改样式后开始出现此错误，并且我添加了一些可填写的区域，例如母亲的年龄，姓名等

Answer 1

我认为您可以尝试一下。

在.env文件中将APP_DEBUG=false更改为APP_DEBUG=true，然后运行以下命令

php artisan config:clear

它将在页面上显示正确的错误如果无法正常工作，请告诉我

Laravel查看错误
