objective-c json php

Question

I'm looking to call a HTTP_POST from the iPhone SDK to a php file on my server. If I call this below:

 NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://*****/api2/index.php"]];

[request setHTTPMethod:@"POST"];
[request addValue:@"postValues" forHTTPHeaderField:@"METHOD"];

//create data that will be sent in the post
NSMutableDictionary *dictionary = [[NSMutableDictionary alloc] init];
[dictionary setValue:@2 forKey:@"value1"];
[dictionary setValue:@"This was sent from ios to server" forKey:@"value2"];

//serialize the dictionary data as json
NSData *data = [[dictionary copy] JSONValue];

[request setHTTPBody:data]; //set the data as the post body
[request addValue:[NSString stringWithFormat:@"%d",data.length] forHTTPHeaderField:@"Content-Length"];

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if(!connection){
    NSLog(@"Connection Failed");
}

php code on server

if ($_SERVER['HTTP_METHOD'] == 'postValues'){ 
$body = $_POST; 
$id;// value1 from dictionary 
$name; // value2 from dictionary
}

Please help with $id and $name

First, the method of this request is POST, not postValues. All you did is add a header with the name METHOD and the value postValues, so, if you want to check for that, you need to look into the interface between whatever server you're using and PHP. For Apache, that's apache_request_headers().

Then, if you're setting the JSON object to be the body of the request, then you need to read the body to get to it. To do that, you need to read php://input. So, your example becomes:

$body = json_decode(file_get_contents('php://input'), true);
$id = $body['value1'];// value1 from dictionary 
$name = $body['value2']; // value2 from dictionary
