WordPress Plugin: Promotion Tool

April 2nd, 2010 by Keith from shrewdies | No Comments | Filed in Form, Function
Many of you looking for a WordPress plugin promotion tool have stumbled across my Happiness Today plugin.

You seem disappointed that the next version is where the real promotion potential lies, but the good news is that you do not need to wait.

If you have downloaded and activated Happiness Today, then you already have a tool for displaying random (or selected) promotion messages in your WordPress posts, pages or sidebar.

The main appeal of Pods is the way it makes extending the WordPress database so easy. But stored data is of little use if you cannot present it to your visitors. My first release of Happiness Today was just to prove that, like Hello Dolly does for standard WordPress, it is very easy to build a basic plugin. That basic plugin instantly demonstrates how Pods stores and displays data. In keeping with the Hello Dolly tradition, I displayed random lyrics in the Admin area – but the real life potential was always to be able to produce something simple yet useful, that can display random promotion messages to visitors.

Those promotional features are included in the current release, just not obvious. Here’s how to use Pods inbuilt features to get more from the Happiness Today plugin. Start your marketing campaign now. (more…)

WordPress Pods: Food For Thought

March 18th, 2010 by Keith from shrewdies | No Comments | Filed in Form, Function
The data-presentation link is vital. To get the best out of WordPress Pods, it pays to study the sample that is packaged with the Pods CMS plugin, and the more advanced examples in the Pods Packages directory.

It is also vital to have a clear plan of the presentation outcomes that you need.

When describing the data aspect of my first plugin, I wrote of the importance of thoroughly analyzing the relationship between the presentation of content required, and the structure of data needed to support it. Recently, I saw a question on the Pods Support Forum that seemed to relate to this area. I was particularly interested in it because the issues seemed to be similar to matters I had encountered with my shrewdBar WordPress menu bar plugin.

The difficulty with forum discussions is fully understanding what the issues are. If one is sat with a client, or even on a video link, it is easy to mock up a quick display and discuss what the presentation should actually look like. Difficulties are compounded with cultural and time-zone differences. But, “All is one in their own way,” and the power of the Internet allows the following attempt at understanding the problem and suggesting a solution.

I hope it solves the problem it tries to address, but even if it doesn’t, I’ve learned a neat CSS trick that I’ll be using again.

WordPress Pods Projects Going For A Song

March 9th, 2010 by Keith from shrewdies | No Comments | Filed in Function
When I introduced my WordPress Pods Plugin Builder yesterday, I hinted at an example project to test the builder with.

I can reveal that this will be an homage to the ubiquitous Hello Dolly plugin – with some extras, and some Pods magic.

Just to remind you. I love Pods as it is intended to be used – a Content Management System that extends WordPress Pages and Posts to allow developers to provide new content styles. This is extremely important to me as I develop new tools for webmasters, and new web applications to extend my health sites.

But for the moment, I’m hooked (pun intended) on using Pods to hook rapidly developed packages into WordPress as plugins. This series of articles explains the Pods features used to create WordPress plugin files complete with readme.txt. WordPress explains what a plugin is by way of the Hello Dolly example. In a similar way, I needed a very simple plugin application to test and demonstrate my WordPress Pods Plugin Builder.

Enter Soft Charisma, the music company run by Scott Kingsley Clark, one of Pods lead developers. Scott has written the perfect song to complement Hello Dolly – Think Of Happiness Today.

WordPress Pods Plugin Builder Taking Shape

March 8th, 2010 by Keith from shrewdies | No Comments | Filed in Function
WordPress Pods CMS plugin is fantastic for adding new content to websites that do not easily fit the standard Page or Post styles.

With it’s easy to use interface, it is good for novice writers, but it also stands on a very powerful data management platform.

This makes it a real candidate for Rapid Application Development, but how to package and distribute those applications?

Before I present my latest project for building structured WordPress plugins, packaged with properly formatted readme file, straight from the Pods interface let me explain what Pods is.

WordPress Database Extension

February 9th, 2010 by Keith from shrewdies | No Comments | Filed in Function
Extending the WordPress database is the first step in developing my menu bar.

In most WordPress extensions, a lot of data is hidden in the code.

The massive advantage of Pods is that we can easily store additional data, and manage it very efficiently.

In the first installment of this series, I introduced shrewdBar, explaining it was based on a WordPress plugin that creates a menu by outputting data in the form of a CSS LIst driven menu. This type of menu is quite common – you style a nested list to have hidden items that reveal themselves when the mouse hovers over them. The added attraction of this type of menu is that without the styling, you simply have a nested list of items that search engines can follow.

The CSS issues are for another time. What I need you to realize is that these menus are usually built in code, with a lot of hard-coded links. True, the original menubar, DashBar, on which shrewdBar is roughly based, does have some items that are extracted from WordPress database tables. In my first version of the menu bar, I extended this to extract messages and topics from the Simple:Press forum.

Pods allowed me to put all the menu items into WordPress database tables, and I explain in this article, how I achieved this.

shrewdBar Database

In its current release, I have limited the menu to two tiers, so we have a Pod for the top tier, that you see across the top of the page. Optionally, each of these top level records can have a variable number of child items.

The schematic is:

shrewdies_bar    link    shrewdies_bar_item
name (txt) name (txt)
slug (slug) slug (slug)
bartext (txt) itemtext (txt)
bartitle (txt) itemtitle (txt)
barurl (txt) itemurl (txt)
baritems (pick shrewdies_bar_item)  ¹——∞ itembar (pick shrewdies_bar)
bardisplay (code)
barhold (bool)

Pods automatically creates the name and slug fields when we create a new pod. name identifies the record, and I also use it as a sort order. slug is very useful in many Pods packages, and I’ll cover it in depth later, but it is not really required in the current version of shrewdBar.

The text, title and url fields are the menu links that are used to navigate to different pages. The pick fields are used to relate tables – in this case a one to many relationship.

The top level menu records have two additional fields. The boolean hold field allows menu items to be temporarily hidden, without deleting the record. This is not required for second level items, as it is a simple click to break or make the relationship to a top level menu. The display field allows us to enter PHP code which can programatically control the display giving us very powerful dynamic menus. I’ll be discussing this at length in the next installment.

shrewdBar Options

Like most plugins, shrewdBar needs options to control colors and positioning. Unlike most WordPress plugins, these options no longer have to live in the options table where they soon get lost. I put the shrewdBar options in its own table, which makes it very easy to manage. The options data could be managed using the standard Pods edit page, however I find it better to write a special page with information and instructions. I’ll be covering this in detail in a later installment.

In the next installment, I will explain how simple Pods procedures act on the data to produce the list output that forms the shrewdBar menu.

WordPress Plugin That Isn’t

February 2nd, 2010 by Keith from shrewdies | No Comments | Filed in Function
This is about the WordPress plugin that isn’t a plugin!

It might become one. It started life as one.

But, for now, it is a Pods package, and this is the first part in a series that explains what a Pods package is, how it improves WordPress functionality, and how you can apply it to your own site.

Before we start, I was reminded earlier about the crucial importance of purpose as your first step. When you set out to add functionality to WordPress, you must be clear about why you are doing it. If you employ assistants, or ask for help on the forums here, or elsewhere, you must communicate that purpose clearly.

Xarzu told me earlier that she wanted to write WordPress plugins and asked if I could recommend a comprehensive list of hooks, actions and filters. I subsequently found she’d asked this in just about every forum on the Internet, irrespective of it’s subject matter. That kind of spam is best ignored, but it does serve as a prime example of what goes wrong when you do not have a clear purpose.

Firstly, I noticed that Xarzu had received lots of positive help, despite the poor question. People want to help, but if the goals are not clear, if the question is too vague, if there is lack of purpose, then that help is often wasted. So before you even think of adding any functionality to WordPress, think long and hard about the purpose of your plugin, and who the typical user is.

My latest project started when I tried the Splix theme, and found the built-in menu bar. It certainly helped me use WordPress as an application, and is a welcome feature of WordPress.com sites. It struck me that as you add functionality to your website, e.g. with forums, polls, news etc, your website becomes an application for your visitors. So I started my WordPress menu bar plugin project.

The purpose of the plugin is to improve navigation efficiency for 3 groups of users:

WordPress Plugins – Developer’s Dream

February 1st, 2010 by Keith from shrewdies | No Comments | Filed in Function
I searched for WordPress Plugins that would help me apply structure to my own efforts.

A scary journey, but now the nightmare is over.

Now I can dream happily of a bright WordPress development future.

But, there is no time to dream. Not even time to hack together a pretty picture to decorate this article. I’m fired up for developing, but there is just enough time to let you know what the plan is.

When I finally decided on the SCB framework, I sat down to plan how to integrate my menu system, a hack of DashBar, into that structure. It looked like a project that might also suit Pods, as I would need somewhere to store menu item links.

What’s the first thing I notice in SCB? Routines to handle WordPress options and table data. But can’t I just use Pods for that?

Yes, I can!

Pods WordPress Plugin

January 30th, 2010 by Keith from shrewdies | No Comments | Filed in Function
The Pods WordPress plugin is driving me crazy.

Mad with admiration one minute, mad with frustration the next.

It’s like breaking your leg when you jump around to celebrate a lottery win. Fantastic find – frustrating failings.

Let me say first, that so far, I believe the potential of this plugin is tremendous. I’m just letting off a bit of steam here because the excitement of finding a truly great WordPress plugin is making me emotional about the rough edges. I am certain those rough edges can be easily smoothed. The proof of the pudding will come in a day or so, when I complete my replacement toolbar.

The developers describe it as:

WordPress evolved.
Pods is a CMS framework for WordPress.
It’s a plugin that sits on top of WordPress, allowing you to add and display your own content types.

I see it as a Rapid Application Development (RAD) tool that could change the way we look at plugins.

Why am I so pleased with this gem?

For months, I have been looking for an easy way to work with extra data tagged onto WordPress. With a background in relational database planning and management, it is frustrating to have to workround things like usermeta & WordPress options. Also, I like simple but comprehensive forms to manage linked data, and it is daunting to have to code a relational database application to integrate with WordPress.

I can see that it can be done. Simple:Press forum is a prime example of integrating a rich database application into WordPress, but it has a scary amount of code and complex field relationships, with little in the way of generic routines that can be adapted for other applications.

Other tools I have seen, only allow simple flat file manipulation, and would need a lot of adapting to tackle relationships. Enter Pods – an easy way to add relational tables as separate applications, or linked into WordPress users or posts. Amazing potential, and amazingly easy to use.

So what are the problems?

Not much if you are familiar with coding, and do not mind getting your hands dirty.

  • The user guide is very poor in examples, and I suspect some of it is out of date, as the plugin is still on a steep development curve.
  • The forum, and the guide, have been radically pruned recently, so just as you think you have found an answer to something – click – 404 not found!
  • Pods has a great way of attaching code to fields called helpers, but the names of these have been changed in the latest release, so many of the example packages do not work. However, it is very easy to find and replace on these, so very easy to fix – I’m just surprised it should be necessary.

So that’s a very brief introduction to Pods. I’ll go and finish the toolbar, then go through some code over the next few posts to show you just how easy it is to build an application. Early days yet, but I think this might be the answer to my nightmare about the lack of good, well-structured example plugins.
