Live Comment Preview (LCP) allows your users to see how their comment will
appear on the site as they type it.

Uses client-side Javascript only (no Ajax requests to the server) which means a
responsive, smooth, live comment preview.

== Installation ==

Use WordPress' built-in plugin installer, or do a manual install:

2. Unzip the archive
2. Upload the live-comment-preview folder to your wp-content/plugins directory
3. Activate the plugin through the WordPress admin interface


== Screenshots ==

1. Comment preview in WordPress' default theme Twenty Twelve

== Frequently Asked Questions ==

= Why isn't the comment preview showing up? =

First, check your theme's comments.php file. It must contain the code
<code>&lt;?php comment_form(); ?&gt;</code> or <code>&lt;?php
do_action('comment_form', $post->ID); ?&gt;</code>. If it doesn't, you will need
to add it in.

Second, if the comment form fields do not have the proper id values (same ones
as the default WordPress theme), the comment preview will not work.

= Can I make the preview display in another location? =

Yes, you can add the code &lt;?php live_preview(); ?&gt; in comments.php where
you want the preview to be show.

= Why doesn't the comment preview look like the rest of the comments? =

Most likely because your theme does not use the standard comment HTML used by
the WordPress default theme. Comments should be wrapped in
<code>&lt;ol class="commentlist"&gt;&lt;/ol&gt;</code>.

= Can I supply my own HTML for the comment preview? =

Yes, simply create a file called comment-preview.php in your theme folder and
insert the strings COMMENT_CONTENT, COMMENT_AUTHOR, and AVATAR_URL where you would
like the respective content to show up.
