PHP has a very shallow learning curve, it's free and anyone can have a go at making a website by following a few tutorials and implementing their experience with other languages. However, coding for the web can be a risky business, especially with dynamic websites that take some kind of user (or external) input and use that to get data from a database.

Wouldn't it be easy to have a single environment configuration for all your SilverStripe sites without having to reconfigure each one individually? Wouldn't it be great not to have to change environment settings when you push your site from development to live servers? This is easy to achieve using the SilverStripe "ConfigureFromEnv" script.

By default SilverStripe uses bulky and sometimes unwanted JavaScript libraries to handle form validation and AJAX page commenting features.

SilverStripes comment system is great when you don't need anything more than the standard feilds, but as soon as you need some extra functionality, things get a little complicated. In this tutorial we will be adding an Email field to the comment form.

When I develop SilverStripe sites, I usually get functionality working in the default theme blackcandy before getting it working in the final templates. This way, authors can start adding content and seeing how it looks on the page, and I can get early feedback about the functionality. Also, as a developer I get to see real content in the browser early in the process. So does the designer.

With all the translatable, i18n and other translation related stuff in silverstripe, I think more than one is wondering how to achieve something simple as using dates in a foreign language... Actually, it's ultra easy if you add this 2 lines in your silverstripe powered website.

TutorialsUsing jQuery for form validation

As you may have noticed, SilverStripes built in form validation is based on Prototype and is pretty limited. It also means that even though you might be using jQuery for other things on your site, you will still need to load prototype.js and all the associated files that SilverStripe requires for it's built in JavaScript form validation.

I have attached a fully working zip-package, but let's run through some of the code nonetheless.

SnippetsOverriding Silverstripes language files with your own

In my most recent project I've had to run a site in another language (Swedish) and run into some issues which I thought I'd share with all of you. Now Silverstripe probably comes with a translation for your language but even if it does, you probably want to change the wording of some of the phrases, so what to do? You could of course hit up the language files for the relevant module or the ones in cms and sapphire but you really don't want to touch these files if you can help it.

As some of you might have noticed, as soon as you step outside of the standard SiteTree structure you're pretty much on your own. Today I had to make a menu that mixed normal SiteTree pages and controller actions.

TutorialsMaking a hierarchy aware templating system

Something that has been bothering me when building larger sites with SilverStripe is that I often find myself creating new classes not to add functionality, but to just get a new template.

You can set separate templates for different actions manually but that's not what I want in this case, I want different templates for the same action on the same class.

After thinking about this for awhile I came up with a two part solution and the first part is to make the template choosing aware of the Sitetree hierarchy.
