所以我有一个if-else函数，它会检查表单中应该是什么，所以当我提交表单时，控制器中的函数会执行if-else函数。所以它的类似，如果隐藏的输入字段中没有值，那么它会将用户重定向回到表单，但是当它这样做时，其他文本输入的所有值都会丢失，用户必须键入所有值再次。我不希望这种情况发生。相反，我希望保留所有其他文本输入。我怎么能这样做？

所以主要的重定向就在这里：
if(!$inputTravel_data['from_country']){
return redirect()->back();
答案 0 :(得分：0)
有时您可能希望将用户重定向到之前的位置，例如提交的表单无效时。您可以使用全局后退辅助函数来完成此操作。由于此功能使用会话，因此请确保调用后退功能的路由正在使用Web中间件组或已应用所有会话中间件：
Route::post('user/profile', function () {
return back()->withInput();
});
