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 the CSS file. The first chapter would have the name of the post, and wouldn't be shown at the beggining of the content. The first occurrence of [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 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, and 3) tho 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´.

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 your wp-config file. This is my personal configuration, modify it as you require it.

• 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");

To get the list of chapters use chap_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(). I use it in single.php in my personal theme.

Screenshots are in spanish because it's my native language. As you should know yet I spe'k english, and the plugin use it by default.
