问题描述
我在这个问题上找到了一些类似的主题，但对于我的情况没有:
i have found some similar topics on this issue, but nothing for my case:
我通过表单发送一些帖子数据，但 $_POST 数组始终为空(不为空).但是当我添加一个死；"或退出"；后 var_dump($_POST);我可以看到所有发送的数据.
i send some post data via form, but the $_POST array is always empty (not null). but when i add a "die;" or "exit;" after var_dump($_POST); i can see all data sent.
也许需要知道，这是在onPreDispatch"上调用的(shopware)插件中.
maybe its relevant to know, that this is inside a (shopware) plugin which is called on "onPreDispatch".
感谢您的帮助
推荐答案
问题是重定向，虽然是在我读取请求中的参数之后重置了帖子.
the problem was the redirect, which resetted the post although it was after i read the parameters in the request.
我不知道，shopware 将所需的数据(paymentID)保存在数据库中.所以我将我的插件切换回onPostDispatch"(这样它会在所有其他操作之后被调用，其中一个将数据保存在 db 中).现在我可以读取数据库并获得相同的数据，这些数据最初位于 post 数组中.
i did not know, that shopware saves the desired data (paymentID) in the database. so i switched my plugin back to "onPostDispatch" (this way it will be called after all other actions, one of them saves the data in db). now i can just read the db and get the same data, which was initially in the post array.
我试图成为阅读帖子的第一个"，但无法解决.现在我是最后一个阅读它的人，它运行良好.
i tried to be "the first" who reads the post, but could not work it out. now i am the last who reads it and it works fine.
感谢所有的回答！这里的线索是重定向".
thanks for all answers! the clue here was "redirect".
