Hackadelic Series PlugIn, Arrr

Jan 31, 2009   //   by Hackadelic   //   WordPress  //  12 Comments

shake your tail featherAye, me hearties, here’s my third WordPress plug-in: Hackadelic Series.

It is the consummation of an idea I gave a quick shot to back in December 2008, when I first had the need for something to support authoring series of posts, and my search revealed no functional lightweight solution for it.

Here is the history of the plug-in.

Sliding Notes Lessons – Beware of HTML Tags In Title

Jan 28, 2009   //   by Hackadelic   //   WordPress  //  5 Comments

<span class=Since I published Sliding Notes, I’ve repeatedly seen people formatting their slider button title italic, and thereby effectively inserting HTML tags into it, like so

[slider title=”some title“]…[/slider]

resulting in: some title»

This is not a practice I’d recommend.

TOC Boxes 1.1 Support Hyperlinks In Headings

Jan 20, 2009   //   by Hackadelic   //   WordPress  //  No Comments

/approveMy first version of Table Of Conten Boxes did not support hyperlinks in headings. That is, a hyperlink in a heading would mess up the TOC entry.1

Version 1.1 adds support for this.

Download the plug-in, or visit the plug-in homepage to find out more about it.

  1. Technically speaking, it would result in a nested anchor element, which is not valid (X)HTML, so that the browser would render only rubbish. []

Sliding Galleries thank to the “Presidential Release”

Jan 19, 2009   //   by Hackadelic   //   WordPress  //  No Comments

lecce [salento]. santa rosa by nightI’m proud to announce that Sliding Notes 1.3.1 successfully cooperates with the Lightbox2 WordPress plug-in. The two plug-ins together provide for a “Sliding Gallery”, as impressively demonstrated by Gage Parker’s portfolio page.

This definitely goes into the Sliding Notes Showcase. 🙂

More interesting use-cases to share? Anybody?

Sliding Notes 1.3.1 Bugfix Release

Jan 18, 2009   //   by Hackadelic   //   WordPress  //  6 Comments

Unfortunately, a small glitch had slipped into the 1.3.0 release that caused sliding notes to be “dead” (not expandable) on the front page. I just released a fixed version, 1.3.1 – a “Presidential Bugfix Release”, if your want 😉

I’m sorry for the inconvenience.

Sliding Notes 1.3 – Hot New “Presidential Oath” Release

Jan 18, 2009   //   by Hackadelic   //   WordPress  //  10 Comments

/approveI haven’t posted anything to my blog in the last week, and I had a good reason: I’ve been preparing a brand new release of Sliding Notes.

Since I published Sliding Notes the first time, I repeatedly had the chance to witness and help with its integration into existing, real world designs. One essential insight I gained from this was that Sliding Notes are being used (or their usage envisioned) in a much wider variety of contexts, than I initially imagined: In the side bar, the content, floating with the text, or stacked, initially collapsed or expanded…[toc class=toc-right/]

As a result of that experience, and just in time for Obama’s upcoming Presidential Oath of Office, I’m releasing a brand new version of the plug-in, packed with features that greatly ease the integration into existing website styles and concepts, as well as the combination of different usage patterns on the same site.

Getting Started With Sliding Notes And MyCSS In 4 Super-Easy Steps

Jan 11, 2009   //   by Hackadelic   //   Featured, WordPress  //  No Comments

[toc class=toc-right style=”max-width:50%”]Since I published my Sliding Notes plug-in, I’ve got several emails from people new to HTML and CSS, or blogging as such, who asked me for guidance to get them started with Sliding Notes (and the MyCSS plug-in for styling).

So I decided to write this simple manual. (Which doesn’t mean I’m unhappy with you folks contacting me 😉 )


To TinyMCE Or Not To TinyMCE

Jan 5, 2009   //   by Hackadelic   //   WordPress  //  No Comments

Woody HamletSome time ago, Mark expressed a wish for sliding notes editor support in form of a button in the visual editor toolbar.

That is, we’re talking about extending TinyMCE here.

Now, I’ve never done that, and I suspect it’d be quite some extra work, but unexplored territories and a rough terrain have never stopped me from trying things out. On the other hand, I naturally ask myself if all that will be worth the effort. Why?

Check it out on the plug-in homepage,1 and have fun with it.

This is the home of the WordPress SEO Table Of Contents plugin: A freely positionable, AJAX-ishly collapsible, CSS styleable, fancy table of contents box for WordPress posts and pages.

[toc style=”margin: 1em 12em”]

WordPress SEO Table Of Contents Features

  • Multiple table of contents boxes embeddable, through multiple shortcodes in the post. Useful for long posts.

WordPress SEO Table Of Contents Usage

The WordPress SEO Table of Contents plug-in automatically recognizes the headings3 in your post, so there’s no need to specifically mark up the table of contents entries.

To position the table of contents box on the page, place the toc shortcode where you want the box to appear. Use the class or style shortcode parameter to make the table of contents box float to the left or right (it’s similar to positioning an image). Use the hint parameter to specify the text shown when the mouse hovers over the table of contents box header.


Note: A WordPress table of contents is never shown on the blog front page, only in single posts and pages. And of course: No headings – no table of contents. (That is, the table of contents shortcode will be ignored if there are no headings in the post.)


Parameter Description
title The title of the table of contents box
hint Hint shown when the mouse is hovered over the table of contents header. Particularly useful when the table of contents box is collapsed.
class Extra CSS classes for positioning and styling the table of contents in addition to its default CSS class, toc.
style Inline CSS style. To specify the width of an individual box, use for ex. style="width: 50%"
auto Should be set to off to suppress auto-insertion on individual posts. Has no effect when auto-insertion is turned off in the settings page.

All parameters except auto have default values supplied via plugin settings from the dashboard. (Note: In the dashboard page, don’t use quotes around the values.)

Predefined CSS classes

The main CSS class of a WordPress SEO Table of Contents box. Most CSS styling is bound to this class.
toc-left, toc-right
table of contents box styling for floating alignments. These are in addition to the above class. For example, to make the table of contents box float to the right, pass the shortcode parameter class=toc-right.

WordPress SEO Table Of Contents Tips And Tricks

RaftaMan reported that some themes (like iNove) contain CSS padding definitions in a way that interferes with the table of contents CSS styling. A workaround is to redefine padding-left in the table of contents CSS for all levels. There is an example is in his comment.

The Story Behind WordPress SEO Table Of Contents

I wanted a WordPress table of contents box similar to the one in MediaWiki, but to my surprize there seemed to be no WordPress plug-in for that.4 Besides, as I tend to prefer a short intro to precede the table of contents, I wanted one that’s freely positionable in the post, and “traditional” table of contents solutions seemed to have implicit positioning at the top only.

So there I was, engineering yet another WordPress plug-in of own, of which I hope it would be to the benefit and liking of a wider audience, too.

If you use this plug-in, please consider making a donation to support the further development. Donate whatever you feel appropriate. Any amount is appreciated.
Thank you.

  1. The maximum heading level to include is configurable. []
  2. Headings are formatted with “Heading x” from the drop-down box in “Kitchen Sink Toolbar” of the visual editor, or wrapped in <Hx>...<Hx/> tags in HTML mode (where x is a number denoting the heading level). []
  3. The maximum heading level to include is configurable. []
  4. At least, not one that does only that. Some series plug-ins include a sort of a table of contents, but I consider it overkill to install a series manager plug-in to get a table of contents, in particular when I don’t quite like the way it’s done. []
