If you ever needed to work with post meta fields and did not want to mess around with validation and all this stuff around it check out http://wordpress.org/extend/plugins/easy-custom-fields/ for a simple set of classes to build on.
<?php
/**
* Automatically insert meta description tag into posts/pages.
* - can be configured to use either first X chars/words of the post content or post excerpt if available
* - can use category description for category archive pages if available
* - can use tag description for tag archive pages if available
* - can use blog description for everything else
* - can use a default description if no suitable value is found
* - can use the value of a custom field as description
*
* @usage
* // add a custom configuration via filter
* function set_meta_desc_settings( $settings ) {
* return array( 'length' => 10, 'length_unit' => 'char|word', 'use_excerpt' => true, 'add_category_desc' => true, 'add_tag_desc' => true, 'add_other_desc' => true, 'default_description' => '', 'custom_field_key' => '' );
* }
* add_filter( 'meta_desc_settings', 'set_meta_desc_settings' );

// as on this page i wanted to have comment threads only collapsed // on category/frontpage and search views but expanded on views with is_single() // to do so open the file in/js.php in your p2 theme and search for p2_toggle_threads // and replace $hide_threads = get_option( 'p2_hide_threads' ); ?> with if ( !is_single() ) $hide_threads = get_option( 'p2_hide_threads' ); else $hide_threads = 0; ?>
Always expand threads in single views with p2theme (http://bit.ly/4oe4xb) #WordPress
