无法通过PHP将NSData上载到MySQL

我正在为我的iPhone应用程序进行服务器端工作，由于某些原因，imageData将不会上传。如果您能看看我的PHP代码，并告诉我是否有问题，我将不胜感激

addImage.php在调用addrecipie方法后调用

我上传图像的Obj-c代码是：

您已经在addImage.php SQL中拼写了配方“recipie”。除非您的表名拼写不正确，否则脚本将返回0行，并且不会运行后续查询。
尽管您在整个过程中似乎都在检查表名的命名方式。不过我要检查一下。是的，我知道。我把数据库命名错了。我搜索了我的代码，问题似乎是addrecipie.php脚本中没有回显id。我收到错误：
您的SQL语法有错误；查看与您的MySQL服务器版本对应的手册，了解要使用的正确语法：2964774和
shortDescription`=shortDescription:1988287``您需要用引号将字符串括起来。将
中的`Name`=$Name和`shortDescription`=$shortDescription
更改为其中的`Name`='$Name'和`shortDescription`='$shortDescription'`非常出色，工作非常完美。谢谢你，本！当您对请求调用
startAsynchronous
时，您是否意识到即使请求未完成，代码仍将继续超过该点？尝试使用
startSynchronous
（不确定这是否是正确的方法，现在无法检查）。是的，您是正确的。我对它进行了编辑，但php脚本返回所添加配方的id肯定是一个错误。
