php - xcode mysql php错误

Question

对不起，这是我在这里的第一个问题。我正在做一个制作应用程序的学校项目，并且在使用 sql php 连接时遇到了困难。

它将空白张贴到数据库中。

我很抱歉格式。我没有包含整个代码，只包含我认为会影响我的结果的区域。

这是我的代码：

预订.h

#define kPostURL @"http://XXX/app/quickbooking.php"
#define kFirstname @"firstname"
#define kLastname @"lastname"
#define kContactno @"contactno"
#define kEmail @"email"
#define kClub @"club"
#define kDatetime @"datetime"

在服务器端（PHP）您使用$_GET全局变量，但在xcode您设置 POST 方法

[request setHTTPMethod:@"POST"];

更改php文件

$_GET to $_POST or to $_REQUEST.
