尝试将日期插入MySQL时出现Flex服务调用问题

标签： php mysql flex datetime flash-builder

我正在尝试为录音室构建一个CRUD应用程序，使我们的客户能够在线预订会话。我有我的数据库设置，我使用Flash Builder 4.6创建一个服务调用，创建一个工作室会话并将信息发布到数据库。我可以将数据从MySQL提取到数据网格，但是当我使用创建会话服务时，我得到一个我似乎无法弄清楚的错误.....＆gt;＆gt;＆gt;在我的php脚本的第123行访问未定义的属性Session_Date。它还说我试图将非对象传递给我的Session_Date-＆gt; toString（'YYYY-MM-DD hh：mm：ss'）。为什么会发生这种情况，有人可以帮助!!!!!我搜索了论坛，但我找不到直接答案。

这是我的PHP类：

class SessionsService {

var $username = "root";
var $password = "bossman1";
var $server = "localhost";
var $port = "3306";
var $databasename = "mydb";
var $tablename = "sessions";

var $connection;

 * received by Zend AMF, an instance of the service class is created and then the

                            $this->password, 
                            $this->databasename,
                            $this->port

答案 0 :(得分：0)

要解决此问题，请打开PHP ini并更改

error_reporting = E_ALL

该声明中可能有E_STRICT。 Zend并不严格遵守:)

祝你好运......

刚刚发现在php 5.4中，e_strict默认启用，所以error_reporting应该是这样的： error_reporting = E_ALL＆amp; 〜E_STRICT
