Prezi Embedder Plugin

This plugin, like most things useful, grew out of a need. I had a Prezi
and I had a WordPress blog. I Googled for a few hours, trying to find a way to embed one within the other, and found some
dirty hacks that ended up not working, as well as a plugin or two that didn’t work, or only half worked. When I realized
that there were no good solutions for this issue, I decided to create one.

This plugin is based on simplicity, making it extremely robust. On the back end, it is actually only a few lines of code.
It takes the embed code that Prezi provides when clicking the share option through their site and simply inserts the
necessary values that are needed to render a working Prezi.

I hope that you all find this plugin as useful as I have!

1. Upload prezi-embedder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Place [prezi id="<Prezi ID>"] in any post or page were you want to embed a Prezi.

To find your Prezi ID, the easiest solution is to simply copy the URL of your Prezi, which should look something
like this: http://prezi.com/<Prezi ID>/<Prezi Slug>. If you paste that URL exactly as it is, the plugin is
now smart enough to extract the ID for you. Alternatively, if you would like to do it the hard way, you can
manually extract the <Prezi ID> from that same URL.

Prezi Embedder Options

In addition to a simple embed, you can also set some additional embed options:

1. align (default = none): Aligns the Prezi left, right, or center in your post.
2. width (default = 500): Width of viewer in pixels.
3. height (default = 400): Height of viewer in pixels.
4. lock_to_path (default = 0): Whether to constrain user navigation to Prezi path (1), or let them roam free (0).
5. autoplay (default = 0): Enables option at bottom of Prezi display to start autoplay.
6. html5 (default = 1): True (1) to use new HTML5 viewer, false (0) to use Flash-based viewer.

The following shortcode is equivalent to [prezi id="<Prezi ID>"], with default values explicitly set:

[prezi id="<Prezi ID>" width=500 height=400 lock_to_path=0 html5=1]
