Back to PHP and Web-based Programming
by FrosT
Introduction
Well due to certain circumstances I have decided to start programming again. If you or someone you know needs a program created please contact me at frost [-at-] aeonity [-dot-] com or david [-at-] aeonity [-dot-] com or using the Contact Form. Let's go into what I can do.
Programming Background
I started programming when I was 13 (currently 21). I am a self-taught individual who loves to think outside the box when it comes to a job. I have a 2-year associate's degree in computer programming. While taking all programming classes in college I received a 4.0 in every class, really I was smarter than the teacher so I opted out to just take online classes and never had to read any of the lessons.
I can currently program PHP, Java, JavaScript, AJAX, ASP, ASP .NET, VB .NET, C#, C++ and just about any other language that gets thrown at me. PHP and JavaScript are the ones I am most fluent in.
Database Integration
Ever wanted a website where users can login and be notified of new services, discounts or pay their balance due? Well with my knowledge of database programming and the use of PHP this can be a very real solution to you. I love working with MySQL databases and creating database schemes. All my databases are created in the 3NF (3rd Normal Form) and created for highest optimization.
Creating and working with a database has to be my favorite part about a project, if you get the database just right than everything else will fall into place.
Object Oriented Programming (OOP)
Object Oriented Programming can prove to be very efficient when coding to resolve errors and easily add/remove certain features that are wanted and needed. Coding in OOP or Object Oriented Programming has been very successful for me in creating fast and efficient websites, such as Aeonity.com and various other projects that I have done over the years. My standards for when I program are to make the code so if you decide to go with someone else to modify the code after the project is said and done anyone who knows OOP can easily step in and do whatever they need to do without having to shift through messy code.
PHP Programming
PHP Programming is definitely my favorite language to program in. With enough power and an open help directory at PHP.net it’s the most logical choice for programming on the web. I have created many different with PHP including web-fetching movie listings, blog websites, content management system, articles, and many others. Soon I will have an example of the movie listings web-fetched I created as it will be open source in a couple of days. Check back for a link on how to download that code, I guarantee it is worth a look.
JavaScript Programming
JavaScript programming ties right into AJAX. I love playing with AJAX as that idea came to me years ago and I could never figure out how to make a call back to the server without refreshing the page. AJAX has provided me with the functionality I have been wanting for a long time. Aeonity is currently using AJAX for certain parts of the website, such as the chatbox and online users. I am hoping to expand the AJAX functionality further for Latest Entries, Newest Users and hopefully in the aspect of creating a blog with automatically saving drafts in intervals for those little mis-haps that can happen.
AJAX is paving the path for the future of web based programming and is setting a high standard. Google.com has implemented AJAX and made its name popular to many with its GMail and Google Maps technology. For truly dynamic content and less page reloads for the end user AJAX is the key.
Ending Notes
If anyone is interested I will bill on a project to project basis. Contact me through email or the contact form and I will talk with you and get a feel for what needs to be done and quote you my price for creating that project. I always get half down up front and than the other half after the project has finished.
Come on; let's spruce up your website with database integration for your end-users. I guarantee that will love that functionality on your website.

Form Real Time Data Checks Using AJAX
by FrosT
Introduction
Filling out forms has always been a pain in the butt throughout the history of the internet. I always hated filling out a form to figure out when I hit the "submit" button I had an error and whoops! The form was erased. Than you beat your computer for 5 minutes and than go back to filling out the form hopefully right this time. Well I ask you this, why do a Postback to check data when you can check it as the user fills out the form.
In this article I will be describing ways to use AJAX for error checking purposes and putting this technology of Javascript and XML to good use.
What Needs to be Checked?
Before we go anywhere we need to ask ourselves, what form fields need to be checked? We may want to check all fields, including optional, or we may want to just check the required and do nothing with the optional fields. First you need to figure out what needs to be checked before being entered into a DB. For example, a date field would probably need to be checked for correct formatting and making sure it is a valid date.
Password Form Checking Logic
Alright here is an example, in words, on how to setup a data check using AJAX on a Password input box. First we need all the AJAX code, too bad I will not provide any. Do research. I will provide logic, you must do the code. Sorry folks. After that there are many different ways to setup the check. If JavaScript is powerful enough for you to verify a password than hey that works, simply use the onkeypress event to check it every step of the way. If that will not due for many reasons here is how AJAX would help you out.
Create the form with the password fields. Next apply the AJAX connect code. Now create a file and call it something like ajax_passwordchk.php. Inside this file will be your logic for checking a password. Now on the input box's for the password field do an onBlur. When they leave the text field the onBlur event will call up the javascript ajax and send the field data to the PHP file. The PHP file will do the checks you define and return a string, a value or something that you can than use to either alert the user that their password is too weak, or does not match the check password field and than send them back to the password box.
Using this logic you can create a pretty cool little check. If you wanted to you could do the onkeypress that updates a label to the side of the password box that tells the user in real-time if the password is too weak, ok, strong, or very strong. If you really go out of your way you can even make suggestions right there given the password they entered. For instance if they used "toilet" you could suggest "t0!l3T" to beef up the password.
Ending Notes
There is the logic that can be used to create a real-time password check on a form using AJAX and PHP. I am sorry no code is provided, there are reasons I will not provide code on blogs, the main reason is my blog is not for showing off code that is what a website is for. Sorry folks, no free code from this blog. If you would like custom code feel free to contact me for a price at frost [-at-] aeonity [-dot-] com.

Asynchronous Javascript and XML Introduction
by FrosT
Introduction
After thinking for a long time I have found a good topic to write about. AJAX or Asynchronous Javascript and XML. AJAX is a recently acknowledged language that combines Javascript and XML into one to provide us with truly dynamic content on a web page that was never though possible before. AJAX hit mainstream once Google.com the search engine giant and guru made use of AJAX inside of it's web applications. Well Aeonity.com has recently started using this technology to improve its website and allow users more ways for interaction with each other. Enough of that, lets go in to detail about how Aeonity.com uses AJAX, Asynchronous Javascript and XML.
Web based Chat
Web based chat has been an issue that many sites have wanted for a long time. It used to be you had to have Java, a Sun Microsystems program to run any type of chat. The Java chat would require the Java client and a connection to an IRC channel/server for the chat to be utilized by people. Well not everyone had the Java client and if they did their browser may not support the version they are using. This caused a problem with a lot of web masters wanting a chat that will work for almost anyone without having to download any extra software.
This is where AJAX comes into play. As you can tell on the index page of Aeonity.com AJAX makes it possible for a web page to connect to a database and provide us with a chat in real time without having a page refresh. How this works is there is a Javascript file with code on the back end. When someone hits the submit button, the button does not register on the page but it accesses this Javascript file. The Javascript file than sends a query string to a particular file which in return connects to a database and does error checking etc. Once that is done data is then sent back to the web page via an httprequest, this is where the XML comes into play, which is written to the page dynamically using javascript'swonderful features. Once that is done we format the data that was returned and than display it nicely and update the page to show us what was recently added to the chat.
Users Currently Online
AJAX is very versatile and powerful. In this sense we can show users currently online with little to no delay unlike before. When a user comes online we can send a signal to a file to retrieve the user information and display it on the page. This combined with session data and AJAX we can show users who are currently online. With a more in depth audit trail we can show more information about the user also if desired. Like the current web page they are viewing, how long they have been on the web page, and when they leave the page. Using this logic we can show when a user has logged off and update the current users online instead of having to time them out after a certain amount of time (usually 5 minutes). This can also be seen on Aeonity.com in the Web based chat area also.
Ending Notes
In short AJAX has brought on a new wave for the computer and Internet guru's. It allows for them to use fairly simple code and provide users with truly dynamic content that is generated at the click of a button without a refresh of a page, and is shown to an end user without any interaction at all. Keep in tune because there may be more AJAX tips and tricks to come of what I learn in my experience coding AJAX, Asynchronous Javascript and XML.
