From b2evolution manual

This manual page is outdated. NEW PAGE: Widgets in b2evolution v5+.

b2evolution skins 2.x now have the ability to handle widgets.

Widgets can be just anything. Think of a widget as a little block of text or HTML that is dynamically generated (or not) and inserted somewhere on your skin (typically the sidebar). Typical examples of a widgets would be the Calendar, the list of categories, etc. But widgets can also be provided by plugins and display weather forecasts for example.

A blog owner can put any widget anywhere he wants it on the skin, provided there is a widget container in that place of the skin. A typical widget container would be the Sidebar. But you will most likely also find a widget container for the Header containing widgets such as the blog title and the blog tagline (you could add a logo widget, etc.).

Skin designers only add widget containers into their skins. The actual widgets are then placed into the containers by each blog owner using that skin. (Note: when creating a new blog, b2evolution populates common containers such as the Header and the Sidebar with some common widgets).

To add a widget container into a skin, a skin designer would use the skin_container() template tag.

To add, remove or reorder widgets in a container, the blog owner would use the admin interface > Blog Settings > Widgets. There is also a shortcut in the evobar under Customize.

Sample Code For Widget for blog title and blog tab

<?php
// ------------------------- "Header" CONTAINER EMBEDDED HERE --------------------------
// Display container and contents:
		
// ----------------------- Blog Title Widget called here -----------------------
skin_widget( array(
        'widget' = > 'coll_title',
        'block_start'       = > '',
        'block_end'         = > '',
        'block_title_start' = > '<h1>',
        'block_title_end'   = > '</h1>',
    ) );
// ------------------------- End of Blog Title Widget --------------------------

// ---------------------- Blog Tagline Widget called here ----------------------
skin_widget( array(
        'widget' = > 'coll_tagline',
        'block_start'       = > '<h2>',
        'block_end'         = > '</h2>',
        'block_title_start' = > '',
        'block_title_end'   = > '',
    ) );
// ------------------------ End of Blog Tagline Widget -------------------------
// ----------------------------- END OF "Header" CONTAINER -----------------------------
?>
