When you extract that zip you will see a folder named Classes and inside that a folder named XMLRPC, drag the XMLRPC folder into your project. You will also need to grab NSString+XMLExtensions.h and NSString+XMLExtensions.m and drag them into your project.

That’s all the required files for the XML-RPC framework and now implementing is fairly straight forward. You need to put the following to your header file:

#import "XMLRPCResponse.h"
#import "XMLRPCRequest.h"
#import "XMLRPCConnection.h"

and to your .m file you need to add something like:

- (NSString *)loginToServer {
	NSArray *args = [NSArray arrayWithObjects:@"test",nil];   // the param(s)
	NSString *server = @"http://example.com/xmlrpc";         // the server
	NSString *method = @"loginUser";                        // the method
	XMLRPCRequest *request = [[XMLRPCRequest alloc] initWithHost:[NSURL URLWithString:server]];
	[request setMethod:method withObjects:args];
	id response = [self executeXMLRPCRequest:request];
	[request release];

	if( [response isKindOfClass:[NSError class]] ) {
		return nil;
	}
	else {
		return [response valueForKey:@"key"];          // the response key
	}
	return nil;
}

- (id)executeXMLRPCRequest:(XMLRPCRequest *)req {
	XMLRPCResponse *userInfoResponse = [XMLRPCConnection sendSynchronousXMLRPCRequest:req];
	return [userInfoResponse object];
}

You need to enter the appropriate values where I’ve commented, but this bare bones example should get you started. You can see more examples by sifting through BlogDataManager.m file in the WordPress for iPhone project.

… and was surprised I couldn’t find one out there on the internet. So, with a *sigh* I rolled up my sleeves and created one. You can check it out it after the break. Merry Christmas :)

Update 22/8/2009: I had to remove the country list because it was messing with my xml feed. You can still get the list here: countries.html

The form worked as expected in Firefox, Safari and Opera (I develop on a mac), but when I tested in IE 6 & 7 nothing happened – you’d click the submit button but the form would not be processed… a rather serious usability issue you might say.

Turns out the issue was to do with the image input type:

In PHP, I had set my form up to start processing on a $_POST['submit'], however IE will append _x and _y onto the image input giving $_POST['submit_x'] and $_POST['submit_y']. A small change to the PHP code and everything was working fine across all browsers:

// start processing on submit or submit_x
if (isset($_POST['submit']) || isset($_POST['submit_x'])) {
	// run code here
}

It is a little embarrassing to admit that I hadn’t noticed this difference before now, but in my defence I will say that I rarely use the image input type for styling my submit buttons. For sites that contain more than one button, a much better solution is to separate the style from the content. I prefer to use the <button> tag in combination with the <a> tag, eg:

Submit
Submit

which can then be styled with something like:

button, a.button {
	background: url(path/to/image.gif) no-repeat top left;
	width: 100px;
	height: 40px;
	display: block;
}

#!/usr/bin/perl
# You may need to change this path to /usr/local/bin/perl

print "\nRunning postwwwacct...";

# set up variables
my $user 	= $ARGV[0];
($name, $pass, $uid, $gid, $quota, $comment, $gcos, $dir, $shell, $expire) = getpwnam($user);
$statsdir 	= "/home/".$user."/public_html/stats";
$webalizer 	= "/home/".$user."/tmp/webalizer";
$tmpdir 	= "/home/".$user."/tmp";

if(eval 'symlink("","");', $@ eq '') {
	mkdir($webalizer, 0755) unless -d $webalizer;
	symlink($webalizer, $statsdir);
	chown($uid, $gid, $webalizer);
	chmod(0755, $tmpdir);
	chmod(0755, $webalizer);
	print "\nPublic stats added for ".$user;
}
else {
	print "\nPublic stats not added for ".$user;
}

exit;

You can then update existing accounts through the command line using:

/scripts/postwwwacctuser username

Where username is the account username you wish to update.

Please note: My knowledge of Perl is pretty basic, so use this script at your own risk. Please post any questions/improvements in the comments.
