NOTE: this article is about using LiveValidation in ChronoForms v3 - it does not apply to ChronoForms v4

In this article I will try to explain how you can dynamically change a TextBox field validation based on a value selected in a DropDown (select) field. Additionally we will create and use a custom validation.

This article will actually make you understand how things work and it only requires some basic knowledge of Joomla, ChronoForms, php, javascript and the LiveValidation class.

Please note this is a tested and working solution. However I'm not a javascript guru. So undoubtedly the javascript code provided can be optimized.

Joomla! 1.6 First Look PDF Print E-mail

Joomla! 1.6 First StepMy work with ChronoForms takes me into all kinds of gloomy nooks and crannies of Joomla!'s code trying to work out how our users can get the results they want.

In the last month or two we have had three major upheavals in quick succession: the MooTools Upgrade plug-in; the release of ChronoForms version 4; and the release of Joomla! 1.6. In effect this means that I am now supporting four different ChronoForms versions. And, of coures, the new releases have brought an influx of new users wanting help. Suddenly all my much valued time for learning about the new Joomla! 1.6 has been taken up.

Joomla! is complex and multi-featured and the new release is surprisingly poorly documented. There are overviews around but little that gets into the nitty-gritty of what is new and how it works.

Eric has taken a first significant step to close those gaps; his excellent 'First Look' is a guided tour to the changes that you can expect when you start to work with the new Joomla! version. In 200 pages he manages to show us what is new; what had been left (more or less) the same and, most importantly, where we need to pay more attention and discover exactly how a new feature functions.

Eric Tiggeler "Joomla! 1.6 First Look"

The eight Chapters are:

  1. Stepping up to Joomla! 1.6: this covers upgrading (difficult) and an oversight of what's new;
  2. Exploring your Enhanced Workspace: new features in the back-end;
  3. Organising and Managing Content: meet nested categories and the new article editor;
  4. Managing Menus and Menu Modules: new admin methods and improved layout;
  5. Managing Site Access with Access Control: by far the biggest change is the intoruduction of flexible user groups and access controls;
  6. New Flexibility in Using Templates: Farewell to tables and hello multiple templates;
  7. Unleashing the New Power of Extensions: New features and controls, and some familiar features removed;
  8. SEO Improvements: new features and a new - and much needed - URL/Redirect manager.

Eric writes smoothly and the book is an easy read - sometimes perhaps too easy: I found that I was hunting for the few words among the many illustrations. Yet it does the job and does it well. You can read this from cover to cover in a few hours; then keep it by your desk to remind yourself when you need a refresher on some topic or other.

Be warned though; this is a driver's manual not a mechanics handbook; you will find very little at all about what is happenning under the hood. There are still plenty of nooks and crannies in the code that have to be explored piece by piece.

How do I get the accent into my name? PDF Print E-mail

Q: How do I get the accent into my name? My name is Roisin, it should be pronounced 'Rozheen', I think it needs an acute accent on the 's' to show this.

A: The spelling with an 's acute' didn't ring quite true so I went digging a little - I hope this will help you!

As far as I can make out Róisín is the Irish word for Rose (possibly 'little rose'). In old Irish it was spelt with an s with a dot above it (not an acute accent), in modern Irish this is usually replaced by 'sh'.Hence you'll find the spelling Roishin is occasionally used (but gets 1,650 Google hits as opposed to 5 million for Roisin/Róisín). See

If you want to use the s+dot version then you can use the character provided that you have a Unicode font installed on your computer. The characters are Unicode 1E60 for the capital letter and 1E61 for the small s - to type them in Word type the code then Alt+x

Most fonts won't contain the characters but Unicode fonts are becoming more common - there's a list at which includes several that are included with Windows or Windows Office.

But there's a downside, Word documents contain the font names but not the fonts so you can't be sure that the recipient will have the same fonts installed and these special characters will show up as a little dot or box if they don't. PDFs will work if font embedding is turned on!

Here are a couple of samples in Tahoma - they look OK here (see the image attached) don't know if they will reach you or not! 1E61 alt+x = ṡ 1E60 alt+x = Ṡ


PS I'm in Brittany so I just looked to see what the Breton version is - Rozenn

My First Book PDF Print E-mail
Written by GreyHead

After nearly a year of hard work my first book is about to be published. The ChronoForms 3.1 for Joomla! site Cookbook is all uploaded to the Packt site and is now available to buy. The book has around 80 recipes for using ChronoForms covering all that you need to know to get forms up and running on your site.

My editors at Packt Publishing gave me a page limit to meet and - inevitably - not all of the material I wrote remained in the final version. Some of the more interesting recipes and the useful “There’s more … ” sections were left out to make sure that all of the important core material was well-covered.

These extra sections might be just what you need if you have an advanced requirement or a knotty problem. So I will be putting them up here as a series of ‘How-to’ documents that you can buy for a few dollars – or sometimes downlaod for free – when you need them.

Why do I see Skype icons on web pages? PDF Print E-mail
Written by GreyHead   
Wednesday, 19 November 2008 05:39

Q: I've noticed recently that a lot of pages I browse to have Skype icons where there are phone numbers. Where have these suddenly come from?

A: When you install or upgrade Skype one of the options is to let Skype install a browser add-on that does this. Sometimes it's useful sometimes it messes up the site. I uninstalled it after a couple of weeks. I Googled and found several sets of instructions for removing it One clear set for IE is at - it also shows you the plugin at work and says how it is installed.

Best wishes
