WordPress meta description tag

WP-meta-description-tag.php

<?php // ** DESCRIPTION v.0.2 **
  if (is_single() || is_page() ) : if ( have_posts() ) : while ( have_posts() ) : the_post(); 
  ?><meta name="description" content="<?php  
  	$descr = get_the_excerpt();
  	$text = str_replace( "\r\n", ', ', trim($descr) ); 
  	echo esc_attr($text);
  ?>" />
  <?php endwhile; endif; elseif(is_home()) : 
  ?><meta name="description" content="<?php bloginfo('description'); ?>" />
  <?php endif; ?>

Problem with v.0.1: this won't filter out "a href" tags. We need to sanitize the content and remove links.

another method:

echo htmlentities(strip_tags(get_the_excerpt()));
