Tag print is called from wp_tag_cloud('smallest=8&largest=16'). One example would be by inserting that function in this part of header.php of the corresponding theme:

1

3

7
8
9
10

	<div class="header">
        	<?php if (is_home()) : ?>
        		<h1><?php bloginfo('name'); ?>
				<span><?php bloginfo('description'); ?></span></h1>
				<?php wp_tag_cloud('smallest=8&largest=16'); ?>
        	<?php else : ?>
		        <h1><a href="<?php echo get_settings('home'); ?>/"><?php bloginfo('name'); ?></a>
				<span><?php bloginfo('description'); ?></span></h1>
	        <?php endif; ?>
	</div>

Another embedding option is to use the famous wp-cumulus plugin.

I found similarity of embedding this kind of file in flash-video-player plugins (I used version 3.1.8). So, I tried to reverse engineer by mind-mapping how it works first and how to hook plugins to WordPress. Here is version 1.1 of the fremind-wp-browser. The final mind-map and plugin in-use in this post looks crowded, but you can find highlighted pointers below the mind-map.

Embedding with SWFObject

The *.mm file is projected over visorFreemind.swf player with the help of javascript.

Using javascript from SWFObject, the idea of flash embedding is to create an SWFObject and then write() that inside certain part of page body, i.e. div.

<script type="text/javascript"> 
   var s0 = new SWFObject("visorFreemind.swf","n0","800","400","7");
   s0.write("video0") ;
</script>

Parsing a Post

In general, the plugins will parse a post content to find [freemind file="path-to.mm" /] shortcode that will finally be replaced by the above javascript with respect to *.mm file that will be played over visorFreemind.swf.

Hooking the Plugins to WordPress

The above javascript needs to be loaded in every head part of each WordPress page, this action will call a function that will insert that script

163

add_action('wp_head', 'FreemindMap_head');

Hence, we get

<script type="text/javascript" src="http://lakm.us/logit/wp-content/plugins/freemind-wp-browser/swfobject.js"></script>

on the header source of every page.

To deal with content parsing looking for the shortcode, add the following filter

166

add_filter('the_content', 'FreemindMap_Parse');

Activation/deactivation of the plugin is via the hook registration where it also create an option panel when activated by adding

99

add_options_page('Freemind Options', 'Freemind', '8', 'freemind-wp-browser.php', 'FreemindOptions');

This initial version has limited options though; enough to set the width and height of the mind-map projection.
