问题
My app uploads an image and user/email/pass upon registration. iOS to php to mySQL. Email,user & pass & image name get saved to the db just fine. Its just the image that is not getting uploaded to the folder on the server. So its just that part of my code which is failing, but can anyone see where? I have this code on my server:
<?

//$image = $_POST['image'];
$photo=($_FILES['photo']['name']);
$password_hint=$_REQUEST['password_hint'];
$noERROR=1;
$udidposted = 9;
//---------------------------------------------------------------------------CHECK IF USERNAME IS LONG ENOUGH
$username = strip_tags(substr($_POST['username'],0,32));

?>
and my iOS code I'm pretty sure is working fine:
-(void)callASIHTTP{
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://www.myserver.com/learn/login/user_save2.php"]];
// Upload an NSData instance
NSData *imageData = UIImageJPEGRepresentation(self.pickedImage, 90);
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request addPostValue:self.userName.text forKey:@"username"];
[request addPostValue:self.userPass.text forKey:@"password"];
[request addPostValue:self.userEmail.text forKey:@"email"];
[request addData:imageData withFileName:self.userName.text andContentType:@"image/jpeg" forKey:@"photo"];
//check if passedData is nil
if (imageData == nil) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"title:iDnil" message:@"msg:iDnil" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];
[alertView release];
}
//completion blocks
[request setCompletionBlock:^{
NSString *responseString = [request responseString];
if (responseString == nil) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"title:rStrg" message:@"msg:rStrg" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertView show];
[alertView release];
}
}];
[request setFailedBlock:^{
NSError *error = [request error];
NSLog(@"Error: %@", error.localizedDescription);
}];
[request startAsynchronous];
}

I know your problem.. I have faced the smilar issue.. You have to give the path for the image.. The following code will get the image from the path.. if the image is in your directory index you have to get the path little different.. Try this and let me know..
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"photo.jpg"];
[request setFile:[NSURL URLWithString:dataPath] forKey:@"photo"];
//IF the photo is in directory index use the following code to get the url
NSString *filename = [[NSBundle mainBundle] pathForResource:@"photo" ofType:@"png"];
[request setFile:[NSURL URLWithString:filename] forKey:@"photo"];
Ok here is the code you have to write for UIImagePicker
- (void) imagePickerController:(UIImagePickerController *)thePicker didFinishPickingMediaWithInfo:(NSDictionary *)imageInfo
{
imagePicker = nil;
UIImage *image = [imageInfo objectForKey:@"UIImagePickerControllerEditedImage"];
image = [image roundedCornerImage:23.5 borderSize:1];
// Get the data for the image as a JPEG
NSData* imageData = UIImageJPEGRepresentation(image, 0.5);
// Give a name to the file
NSString* imageName = @"photo.png";
// Now, we have to find the documents directory so we can save it
// Note that you might want to save it elsewhere, like the cache directory, or something similar.
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
// Now we get the full path to the file
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:imageName];
[imageData writeToFile:fullPathToFile atomically:NO];
myPicture = imageData;
myPicturePath = fullPathToFile;
// Dismissing the image picker view
[self dismissModalViewControllerAnimated: YES];
}
While uploading the image use this code.. You will have the myPicture path set from the image picker..
Request setFile:myPicturePath forKey:@"photo"];
The following code is to get the image from the document directory and send it..
NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString* documentsDirectory = [paths objectAtIndex:0];
// Now we get the full path to the file
NSString* fullPathToFile = [documentsDirectory stringByAppendingPathComponent:@"photo.png"];
[imageData writeToFile:fullPathToFile atomically:NO];
[Request setFile:fullPathToFile forKey:@"photo"];

I know that it is silly, but I had a similar problem only to find it was folder permissions on the web server.
