Dynamically change z-index on Google Maps markers

As many have noticed Google Maps API does not include a setIndex() method on the marker. You can set the z-index when adding a marker to the map. But it is not possible to change this afterwards.
I didn’t find a good solution to the problem when searching and had to resort to my own, hacking [...]

International PHP conference in Frankfurt 2007

Yesterday was the first day of the International PHP Conference. I listened to Lars Jankowfsky in his session “Practising Agile Development”. Although different methodologies were mentioned it was mainly a one day session on how Extreme programming works. The session had a good mix of fun och seriousness. One of the reasons I wanted to [...]

Reordering nested sets using PHP and Javascript

The adjancency method
Representing a tree of nodes, for example product categories, in a relational database is not hard. The most common way of doing it is to store a parentid with each node.

PHP 5.2 ajaxified

PHP 5.2.0 was released a few weeks ago. Apart from the usual bigger, better badder there are two small additions that I think are worth mentioning.

A new extension for JSON decoding and encoding enabled by default.
Hooks for tracking file uploads.

These features aren’t competing for the heavy weight title in the release notes. Still, having these [...]

Cross site scripting

While looking around for cross site scripting resources I stumbled upon this “ha.ckers.org” site which is an excellent source for ideas on how to check for XSS vulnerabilities. I have seen it before but I obviously forgot to bookmark it. Now I saw the site listed in the top of  del.icio.us/tag/xss as well. Another good [...]

Aspect Oriented Programming and javascript

After investigating AOP a bit more I am convinced that the concept is well worth the effort. I really like object oriented architectures as I think it is a good way of modelling applications. I don’t like to overdo it though. In PHP projects I often end up with a few classes and a lot [...]

Announcing Toxic – an Ajax toolkit

The project is no longer available. Might be so in the future.
Recently I have been working hard on my SRSS (whatever) project. The result is nearly finished and has been dubbed Toxic.
Toxic is an AJAX toolkit, or framework, for creating rich web applications. It handles the tedious and repetetive tasks involved in integrating a client [...]

Google Web Accelerator

Recently the Google Web Accelerator (GWA)has received a lot of attention from web application developers. Rightly so. When installing GWA for use in your browser it speeds up surfing by prefetching pages. This can be very useful but also extremely dangerous as it has very bad side effects on many (badly designed) web applications. Why? [...]
