How to do an AJAX search with jQTouch, Part 2

In the last installment of How to do an AJAX search with jQTouch we looked at how to setup a jQTouch interface with the goal of performing an AJAX search. In this article, we will write the necessary JavaScript to perform that AJAX search, as well as a PHP script to respond to those calls.

This article assumes you have read the first part of this series.

How to query posts by template in WordPress

Ever wanted to filter a query_posts call by template? If you’re reading this post, you probably have or need to right now. You probably went to the query_posts documentation and scanned for something like “template=foo” and were deeply disappointed. Then maybe, in an act of desperation, you started to trudge around the plugin library. Stop! Stop right there! You don’t need a plugin to do this. Everything you need is already in WordPress.

PHP interfaces and optional parameters

Interfaces in object-oriented languages like Java, C# and PHP are useful language constructs for ensuring that objects will respond to certain methods. However, unlike Java and C# (until recently), PHP has optional parameters. As it turns out, this feature has an interesting (and a little bit unexpected) effect on how we can implement interfaces in PHP.

Adding Extension Methods to PHP

If you’ve ever used the .NET Framework version 3.5 of later, you’ll probably have encountered extension methods. Microsoft describes extension methods as:

Extension methods enable you to “add” methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type.

In this article, I will show you how to write a base class that will allow you to add methods to any PHP class that inherits from it at runtime. You will be able to call these methods transparently, without any special syntax.

How to do an AJAX search with jQTouch, Part 1

jQTouch is a pretty nifty little jQuery plugin for making websites look like native iPhone apps. Unfortunately, beyond a bunch of examples included with the distribution, there’s not a whole lot of online documentation written for jQTouch. Having started to use jQTouch for a professional project, I thought I’d help remedy this deficiency by posting what I learned along the way.

We’ll start with something fairly straightforward by making a jQTouch app that makes an AJAX call to a PHP script to search a database. It then displays the results of that search in the jQTouch app. This article is split up into two parts. The first part deals with the jQTouch UI and the second part deals with the PHP script and the supporting JavaScript.

This is part 1 of a two part series.

Convert PHP date format string to .NET DateTime format string

I recently had to convert some JavaScript code I’d written that used a PHP-style date format string to a .NET DateTime-style date format string.

It would’ve been a helluva lot faster to have had some sort of conversation table. After a little searching on Google, I found nothing so I decided to make one myself. Behold, the fruits of my labour!

Consuming a J2EE Web Service with PHP SOAP

I recently had to do some work for a company which involved using PHP to consume a J2EE-based WSDL web service. The project was fairly straightforward, involving only a one-way call to the web service, i.e. no result needed to be collected.
