Altering text in Drupal 7 is quite simple thanks to things like string overrides that allow you to replace all instances of a string throughout a site. If you want to change a single element on a single form then string overrides don't quite work, but using hook_form_alter() or hook_form_form-id_alter() allows you to manipulate any form in a Drupal site.

Changing the text of a submit button when clicked can be useful if you are writing an AJAX application or you know that there will be some sort of delay. Providing the user with some form of feedback is a useful way of letting them know they they have done something.

First, we need a form to work with, so I built a quick one here. Notice that the submit button has an onclick action associated with it, this will be used later to enable us to alter the text of the button.

Building your projects into directories is nice, but distributing these projects is difficult if you have to build the compressed files yourself. Phing has the ability to create zip and tar files using simple commands.

The most convenient way of using the tar and zip commands is by using a fileset. But rather than use the fileset that was used to copy the files into the build directory it is best to create a separate fileset that is used to compress the contents of the build directory.

Following on from my previous blog post about installing Flex on Windows I thought I would go through how to create an interface using mxml. When you create a Flex 3 project the first file you are given is called Main.mxml, which has the following content.

Creating a simple highlight effect is quite easy when you use the JavaScript framework mootools.

The first thing to do is grab the mootools library from the site and link it in your web page. You can select different components with mootools, but if you grab the whole thing you can start to play with whatever you want. Put this line of code in the head section of your web page.
