Inline Validation for Symphony
------------------------------
@version	1.0
@release	10th September 2009
@jquery		1.3.2

Allows you attach inline Ajax validation to your forms.

The validation appears on inputs and textareas after the user
has filled them out (why validate on nothing..). The error

A Meta Keys field allows you to add arbitrary pieces of information to entries identified by a user generated key. The interface resembles the section editor in that any number of keyed information could be added to an entry (interface possibly provided by the Stage extension).

The values would always be text (at least initially).

For instance, a Meta Keys field could be added to a Products entry and then filled with this data:

• Colour: Red
• Size: 500ml

A datasource could then filter on the keys (in a yet to be determined syntax), eg. color=red.

Overview

The inner workings of the magical $this->_Parent have always been a bit of an unknown to Symphony developers and therefore, several ways have cropped up of doing the same things. Starting with Symphony 2.2, there is now a recommendation of how extensions should correctly use this variable.

In the early Symphony 2 days, $this->_Parent was used to manage a catalogue of all the available Managers and other objects such as Configuration and Database so extensions could use these instead of creating their own. Efforts were made in Symphony 2.0.6 to help cleanup this catalogue structure (which is memory intensive) by introducing static accessors to Symphony::Database() and Symphony::Configuration(). These allow extensions to reference these objects regardless of the instance Symphony is operating in (Frontend or Administration).

A typical Field extension works in both instances, functions such as displayPublishPanel work in Administration, others, such as `appendFormattedElement

Watch & Learn

• Watch the Think Vitamin videos
• Watch Paul Irish's "Things I've learnt from the jQuery source code"
• Learn to use SimpleTest, or any other Unit Testing library, that may help speed up Symphony development (CW: Rowan would probably have some ideas, or may have some experience in this already)
• Read about UX in general
• Read some Graffle tutorials to get more productive

Forms have been an integral part of any interactive site since the dawn of time, they promote interactivity and are usually the most common way users interact with a site. It's commonplace that when a form is submitted, the website will take 'action' and do something with the data and then provide a user with the result. Symphony provides this logic layer via Events.

This tutorial assumes you have a basic understanding of how Events work in Symphony (if not, this may be a good introduction) and are semi comfortable writing some PHP code. I'll be showing you some of the lesser known features of Symphony Events, including event priority, event chaining and a brief demonstration of how to write a custom Event. The difficulty level progresses as we go through, but with any luck you'll be able to learn a thing or two :)
