Este plugin no se ha probado con las últimas 3 versiones mayores de WordPress. Puede que ya no tenga soporte ni lo mantenga nadie, o puede que tenga problemas de compatibilidad cuando se usa con las versiones más recientes de WordPress.



The nextpage tag in WordPress gives a simple indexing system, but
sometimes we need a better solution. Indizar creates chapters with
titles and gives a function to retrieve those names. Also it has a
tool to put an index whereas the user wants in the post, or a tag to
define a default configuration for the boxes.

To add a chapter use [chapter:Title] at the beginning of the chapter.
The title would be write as a header, and you can define the apparance
with a CSS file (see the FAQ). Notice that the first chapter in the list
would have the name of the post, and wouldn’t be shown at the beggining of
the content. The first occurrence of the tag [chapter: ****] would be the
second item in the chapters list.

If you need another name for the first chapter you can use [firstchapter:Title]
to create a header. It doesn’t have to be at the beginning of the page.
With this you can have an introduction and the first chapter in the same page.

To allow Indizar to use the ´headers´ as chapter marks, you have to define it
in your wp-config file. Read the topic about how to modify Indizar
configuration at the end of this README.

To add the index use [chapters:size,left|right] where size is the width
of the context box, left | right is the float position for the box. Those
values are optional and you can use just [chapters]. The index box is
hidden in the index and search pages, it will be shown in each ‘single page’.
Use the configuration tag instead this if you want to show a box in every
page at the same place.

To add a global configuration use [indizar:#conf,#box_size,[left|right|none],{preface_title}],
where the #conf is:

  • 0 – to not show a numbered list
  • 1 – to show it at the begin of the post
  • 2 – to show it at the end
  • 3 – to show it both sides

The size box and the float position declares the general behavior. If the float value is
´right´ or ´left´ the plugin creates a box after every chapter title in the post,
if it is ´none´ the plugin will let you define the chapters box manually with the
tag [chapters]. If there is a [chapters] tag in a page the plugin will use this
position instead the one declared in the ´configuration´ tag. The ´preface_title´
is optional and if declared the first chapter would be numbered as 0 and the
text you use will be the title in the numbered list.

Why use a preface? Maybe the first chapter of your post is really the second page,
and when you look at the URL the fisrt chapter is named ´post/chapter/2´. This
sets correctly the url to show your first chapter as ´post/chapter/1´.

To not display a chapter list in a page when you have a configuration set, use the tag

There is a button in the RichText Editor to add chapters, chapters box and the
configuration tag to your post.

If you want Indizar to have a default configuration you can declare it in
the wp-config file. This is my personal configuration, modify it as you

  • define(«INDIZAR_TOP», false);
  • define(«INDIZAR_BOTTOM», true);
  • define(«INDIZAR_BOX», true);
  • define(«INDIZAR_BOX_SIZE», 200);
  • define(«INDIZAR_BOX_FLOAT», «right»);
  • define(«INDIZAR_USE_PREFACE», false);
  • define(«INDIZAR_PREFACE_TITLE», «Prefacio»);
  • define(«INDIZAR_USE_HEADERS», «h1»);
  • define(«INDIZAR_DIV», «.entry-content»);
  • define(«INDIZAR_TOPDIV», «#box»);

The INDIZAR_DIV and INDIZAR_TOPDIV are required only if you want to enable
the AJAX feature. The first one requires the class or the id of the div containing
the text you want to change. The second one requires the class or the id of the
tag where you want to scroll when using the links at the end of each chapter. In
the example, indizar would change the content inside the class ‘entry-content’ and
will scroll to the id ‘box’. These are the data for my theme, but it would be
different in yours

To get the list of chapters in your theme, use the function ind_chapters_list(). This
function returns the array with the chapters, or false if there are no chapters.
It has to be used after the function the_post(). Or, to get the html, use $list = ind_chapters_list(); echo ind_index_list($list);

  1. Decompress and upload /indizar/ to the /wp-content/plugins/ directory.
  2. Activate the plugin through the Plugins menu in WordPress
  3. If you use permalinks, go to Options > Permalinks and press the button Save Changes. This would recreate your permalinks cache with the chapter tag.
  4. You can use indizar.css to create your own style. Copy it to your theme idrectory.
  5. If you want a default configuration define it in your wp-config.php file.

Preguntas frecuentes

Is this plugin bug free?

I don’t think so. So far it works with my permalinks, but I didn’t test it with other
configurations. Feedbacks would be appreciated.

Permalinks doesn’t work!!!!!!

Did you recreate permalinks rules? Go to Options > Permalinks and press the button Save Changes.

Can I set my own CSS?

Yes. Copy the file indizar.css to your theme folder. The plugin will check for it.

Can I use the Ajax script in my theme?

Yes, use the script ‘indizar_click(url, div, jump)’.
* Url is the link to the page.
* Div is the class or id where the content is.
* Jump is the class or id of the tag where you want to scroll. Set this to false
if no scroll is required.

If you use a jQuery call to set the binds, remember to create te bibds again because
the new content has new DomObjects.
