Question

I’m sorry but this is my first question on here. I’m doing my school project of making an app and is having difficulties with the sql php connection.

It’s posting blanks into the database.

I’m sorry for the format. I did not include the whole code, only the areas that I think affects my results.

Here’s my code:

Booking.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"

Answer 1

In server side (PHP) you using $_GET global variable, but in xcode you set POST method

[request setHTTPMethod:@"POST"];

Change in php file

$_GET to $_POST or to $_REQUEST.
