为什么单击搜索按钮后出现分页错误？
为什么单击搜索按钮后出现分页错误？
提问于 2018-07-25 04:08:43
我有一个"https://proj.test/user/profile?user=2#myRegistrations“页面，其中我有两个选项卡，一个选项卡显示用户在会议中的过去注册，另一个选项卡显示用户在会议中的下一个注册。用户可以点击“过去的注册”来检查过去的注册，并点击“下一次注册”来检查他在会议中的下一次注册。而且它起作用了。
在这个相同的页面中，在选项卡上方，我有一个供用户搜索其注册的会议名称的表单。但是，当用户在表单搜索输入中输入一些文本，如“测试”并单击“搜索”时，它会显示为"Undefined property: Illuminate\Pagination\LengthAwarePaginator::$participants (View: /Users/john/projects/proj/resources/views/users/index.blade.php)“。你知道什么是问题所在吗？
