Question

我知道这听起来很疯狂，但我知道“BasicNameValuePair”实际上已被弃用！但我的老板告诉我出于某种原因使用它。我有多个复选框，用户需要选择他们的兴趣，这些数据被发送并保存在mysql数据库中。我的问题是一切正常，但我只获得了被点击保存在数据库中的最后一个值。尽管如此，我还尝试了"interests[]"，但这也没有帮助。

我选择兴趣的活动

}

我已经从我的php“interestPage.php”文件成功建立了与数据库的连接。以及如何在PHP脚本中执行“兴趣”数组。我基本上使用"switch ( $_POST['userInterests'] ) {......."

Answer 1

您是否设置了onCheckedChangedListener或OnClickListener？

Answer 2

我认为，因为您在storeUserCheckBox中致电onCreate并且每次都向服务器发送数据 - ＆gt;如果用户点击一次复选框，他们的共同作用NameValuePair将一直退出。

我认为你应该在发送到服务器之前清除dataToSend：

user = userLocalStore.getLoggedInUser();
dataToSend.clear();
dataToSend.add(new BasicNameValuePair("userID", user.userID + ""));

//Method to store the click checkbox to the "Data to Send" array
storeUserCheckBox();

将数组传递给BasicNameValuePair？
