Multiform data send to server using iPhone sdk - xcode

Question

I’ve been trying to follow some examples for uploading data to a website. I want to save the message as a .txt file. Any ideas what to do here?
- (IBAction)sendSerializedGreeting:(id)sender;
{
NSString *message;
message =#"Here we go for a test message.";
// Show a loading indicator
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
NSString *greetingURL = [NSString stringWithFormat:#"http://www.site.com/upload.php"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:greetingURL]
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSDictionary *headerFieldsDict = [NSDictionary dictionaryWithObjectsAndKeys:#"text/xml; charset=utf-8", #"Content-Type", nil];
[theRequest setHTTPBody:[message dataUsingEncoding:NSUTF8StringEncoding]];
[theRequest setAllHTTPHeaderFields:headerFieldsDict];
[theRequest setHTTPMethod:#"POST"];
// create the connection with the request and start loading the data
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if (theConnection == nil)
{
NSLog(#"Failed to create the connection");
}
}
Here is the upload.php file. I’m assuming the issue is with this but not sure. I don’t know where the filename gets set in the example above. This code was used from somewhere else.
<?php
$uploaddir = './'; //Uploading to same directory as PHP file
$file = basename($_FILES['userfile']['name']);
$uploadFile = $file;
$randomNumber = rand(0, 99999);
$newName = $uploadDir . $randomNumber . $uploadFile;
if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
echo "Temp file uploaded.";
} else {
echo "Temp file not uploaded.";
}
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) {
}
?>

I am sending a image to server through this code .... use for your text file or any type of multiform data
NSString *strUrl=#"http://www.site.com/upload.php";
NSLog(#"%#",strUrl);
NSURL *url=[NSURL URLWithString:strUrl];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
cachePolicy:NSURLRequestUseProtocolCachePolicy
timeoutInterval:130.0];
// file name of user picture
// I am sending a image to server
NSString *fileName=[[eMailTxtField.text stringByReplacingOccurrencesOfString:#"#" withString:#"-"] stringByAppendingString:#".jpg"];
//image data
UIImage *userImage=imgUser.image;
NSData *imageData =UIImageJPEGRepresentation(userImage, 90);
NSMutableData *myRequestData = [[NSMutableData alloc] init];
[myRequestData appendData:[NSData dataWithBytes:[postData UTF8String] length:[postData length]]];
NSString *boundary = [NSString stringWithString:#"--"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
[myRequestData appendData:[[NSString stringWithFormat:#"\r\n--%#\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[myRequestData appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"uploadfile\"; filename=\"%#\"\r\n", fileName] dataUsingEncoding:NSUTF8StringEncoding]];
[myRequestData appendData:[[NSString stringWithString:#"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[myRequestData appendData:[NSData dataWithData:imageData]];
[myRequestData appendData:[[NSString stringWithFormat:#"\r\n--%#--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[ request setHTTPMethod: #"POST" ];
[ request setHTTPBody: myRequestData ];
NSURLResponse *response;
NSError *error;
NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse:&response error:&error];
if (!error && returnData) {
NSString *content = [NSString stringWithUTF8String:[returnData bytes]];
[self registerWithJsonString:content];
}
else{
[self showServerNotFoundError];
}
