Heres what ive learned so far. There are four wordpress functions that are key in making a smooth site registration work. First you must make use of the new site validation functions which are:

$username_exists = username_exists($user_name); // check sanitized username
$email_exists = email_exists($user_email);

if ($username_exists) die("username already $user_name in use.");
if ($email_exists) die("the email $user_email is already in use. ");

// get validation result for multi-site fields
$validation_result = wpmu_validate_blog_signup($site_address, $site_title);

$error_msg = (isset($validation_result['errors']->errors['blogname'][0])) ? $validation_result['errors']->errors['blogname'][0] : false;
if($error_msg != false) die($error_msg);

$error_msg = (isset($validation_result['errors']->errors['blog_title'][0])) ? $validation_result['errors']->errors['blog_title'][0] : false;
if($error_msg != false) die($error_msg);

Assuming your form has passed the necessary fields $user_name, $user_email, $site_address and $site_title. These functions will make sure the username or the site address doesn’t already exists. if it does it simply halts the script.. Obviously you may want to create a more graceful error notice to the user.

Once all the important information is validated, you can move on to create the username:

</span>
<pre>$user_id = wp_create_user( $user_name, $password, $user_email );
if(is_wp_error($user_id)) die($user_id->get_error_message());

// set user metadata
update_user_meta($user_id, 'first_name', $firstname);
update_user_meta($user_id, 'last_name', $lastname);
update_user_meta($user_id, 'phone', $phone);
update_user_meta($user_id, 'package', $package);

// set user role
if(!empty($role) || $role == 'subscriber') {
	$userobj = new WP_User($user_id);
	$userobj->set_role($role);
}

// send user/admin notifications
wp_new_user_notification($user_id, $password);

And finally create the site and assign the user we just created as administrator of that site:

create_new_multisite($user_id);

function create_new_multisite($user_id) {
    global $wpdb, $current_site, $base, $site_address, $site_title;

    $user = get_userdata($user_id);

    // get the domain name
    $domain = '';

    if(!preg_match( '/(--)/', $site_address) && preg_match('|^([a-zA-Z0-9-])+$|', $site_address) )
        $domain = strtolower($site_address);

    // get the site title and user email
    $email = $user->user_email;

    // final check to make sure our essentials are good to go
    if(empty($domain) || empty($email) || !is_email($email))
        die('no domain or email or invalid email');

    if(is_subdomain_install()){
        $newdomain = $domain . '.' . preg_replace( '|^www\.|', '', $current_site->domain );
        $path = $base;
    } else {
        $newdomain = $current_site->domain;
        $path = $base . $domain . '/';
    }

    // create the new site!
    $id = wpmu_create_blog($newdomain, $path, $site_title, $user_id , array( 'public' => 1 ), $current_site->id);

    if(is_wp_error($id)) { die($id->get_error_message()); }

    $dashboard_blog = get_dashboard_blog();
    if(!is_super_admin($user_id) && get_user_option('primary_blog', $user_id) == $dashboard_blog->blog_id)
        update_user_option( $user_id, 'primary_blog', $id, true );

    //send new site notifications
    $content_mail = sprintf(__( "New site created by %1s\n\nAddress: http://%2s\nName: %3s", "jummelreg"), $current_user->user_login , $newdomain . $path, stripslashes($site_title));
    wp_mail(get_site_option('admin_email'), sprintf(__('[%s] New Site Created', "jummelreg"), $current_site->site_name ), $content_mail, 'From: "Site Admin"     wpmu_welcome_notification($id, $user_id, $password, $site_title, array('public' => 1));

}

Instead of trying to assign event handlers to each button one by one, i setup a for loop like the following:

for (var i:int=1;i<=5;i++) {
	this["btn"+i].addEventListener(MouseEvent.CLICK, clickHandler);
	this["btn"+i].addEventListener(MouseEvent.MOUSE_OVER, overHandler);
	this["btn"+i].addEventListener(MouseEvent.MOUSE_OUT, outHandler);
}

The for loop will loop through all five of your btns and assign the mouse click, rollover and rollover events for each. Simple

Once you grasp that concept, then its time to inject metadata into the button itself so that each mouse event handler can use that data.

say we have an array of info for each button, which would contain a title, and description.

var buttonData:Array = new Array(["title 1","description 1"],
					["title 2","description 2"],
					["title 3","description 3"],
					["title 4","description 4"],
					["title 5","description 5"]);

now, in out loop we can target that data, and inject it into the button movieclip instance. like so:

for (var i:int=1;i<=5;i++) {
	this["btn"+i].addEventListener(MouseEvent.CLICK, clickHandler);
	this["btn"+i].addEventListener(MouseEvent.MOUSE_OVER, overHandler);
	this["btn"+i].addEventListener(MouseEvent.MOUSE_OUT, outHandler);
	this["btn"+i].title = buttonData[i][0];
	this["btn"+i].desc = buttonData[i][1];
}

once that data has been injected.. we can access it at any time, in any of our mouse events like so:

function clickHandler(e:MouseEvent):void {
	trace("title: "+e.currentTarget.title);
	trace("desc: "+e.currentTarget.desc);
}

the full script would look something like this (just make sure you have 5 buttons with the correct instance names on the stage):

var buttonData:Array = new Array(["title 1","description 1"],
					["title 2","description 2"],
					["title 3","description 3"],
					["title 4","description 4"],
					["title 5","description 5"]);

for (var i:int=1;i<=5;i++) {
	this["btn"+i].addEventListener(MouseEvent.CLICK, clickHandler);
	this["btn"+i].addEventListener(MouseEvent.MOUSE_OVER, overHandler);
	this["btn"+i].addEventListener(MouseEvent.MOUSE_OUT, outHandler);
	this["btn"+i].title = buttonData[i][0];
	this["btn"+i].desc = buttonData[i][1];
}

function clickHandler(e:MouseEvent):void {
	trace("title: "+e.currentTarget.title);
	trace("desc: "+e.currentTarget.desc);
}
function overHandler(e:MouseEvent):void {
	trace("over event: "+e.currentTarget)

}
function outHandler(e:MouseEvent):void {
	trace("out event: "+e.currentTarget)
}

What people don’t understand about developers is, even if Flash did die, It’s not like were out of a job. We, as developers, use whatever tools are available to us to get the job done. And in the process, we come up with new and clever ways to solve problems. People think that if our title is Flash Developer, than all we know is Flash. Wrong. To even get Flash running on a website you have to know a little bit of HTML CSS and why not JavaScript. We have a multifaceted skill-set that shouldn’t be underestimated.

I think a lot of developers are waiting for HTML5 to mature a bit more. One of the main reasons I’m not using HTML5 heavily yet is because there isn’t any support for protected video streams. Be it, DRM or streaming video through RTMP which flash is notorious for.

Do I believe Flash will die soon? Maybe, but I’m not holding my breath. So all you Flash is dead chanters can keep on chanting. Were not listening. We don’t need too. Were already three steps ahead.

Today we had the quick job of posting some data to Travel Click’s iHotelier application. We had a client that has a hotel (obviously) and needed their reservation form connected to ihotelier’s web based reservation application.

I figured it would help someone if i documented the steps it took to send data to them..

We placed the form action to ihotelier appication and you end up with a page like this:

The main thing to know is that the ihotelier application accepts $_GET data in a certain formation as follows:

• DateIn
• DateOut
• Adults
• Children
• Rooms
• HotelID
• LanguageID

The full url that we ended up posting to was something like:

https://reservations.ihotelier.com/istay.cfm?DateIn=9/1/2011&DateOut=9/7/2011&Adults=1&Children=0&Rooms=1&HotelID=13187&LanguageID=1

Its actually a pretty simple system once you know the variables it wants. We had to figure it from trial and error unfortunately.

Hope this helps.. See ya!

Hope you’re all as excited as we are.

We plan to post a lot of blog tutorials showing step by step procedure on a lot of the cool things we make here. Stay tuned.
