   thematic_content defines the way that full content pages and excerpts look in thematic. has anybody ever created a different type? i've done that before, but this time i am specifically looking to create a type that first looks for full content before a <more> tag and then failing that autogenerate an excerpt. any thoughts?

   so for example, i'd first define that i want to use this new 'type' on category pages

   function childtheme_content($content) {
   	if (is_category()) {
   		$content= 'more';
   	}
   	return $content;
   }
   
   add_filter('thematic_content', 'childtheme_content');

   and then hypothetically something like

   `
   function childtheme_more($post){

   /* if (has <!--more--> tag) {
   $post = content up until more tag;
   } else {
   $post = get_the_excerpt();
   }
   */

   return $post;
   }
   add_filter('thematic_content','childtheme_more');

   solved this for anyone who cares to know. the first part above is correct... you must filter thematic_content and tell it where to use this new "type". and now to filter thematic_post

   function childtheme_excerpts($content) { //normally i'd call $post here as that is what thematic uses,  but that caused problems with the next line
   	global $thematic_content_length, $post; //needed to declare the standard $post object
   
   		if ( strtolower($thematic_content_length) == 'more' ) {
   
   			if ( preg_match('/<!--more(.*?)?-->/', $post->post_content ) ) {  //here's where i needed to the $post object. didn't seem to work at all with get_the_content()
   				$content = get_the_content(more_text());
   				$content = apply_filters('the_content', $content);
   				$content = str_replace(']]>', ']]>', $content);
   
   			} else {
   				$content = '';
   				$content .= get_the_excerpt();
   				$content = apply_filters('the_excerpt',$content);
   				if ( apply_filters( 'thematic_post_thumbs', TRUE) ) {
   					$content_title = get_the_title();
   					$size = apply_filters( 'thematic_post_thumb_size' , array(100,100) );
   					$attr = apply_filters( 'thematic_post_thumb_attr', array('title'	=> 'Permalink to ' . $post_title) );
   					if ( has_post_thumbnail() ) {
   						$content = '<a class="entry-thumb" href="' . get_permalink() . '" title="Permalink to ' . get_the_title() . '" >' . get_the_post_thumbnail(get_the_ID(), $size, $attr) . '</a>' . $content;
   					}
   				}
   			}
   
   		} 
   
   	return $content; //send it back to the function. by using $content here i don't monkey with the $post object which was breaking the 'excerpt' and 'full' types. thematic_post will take this variable as the $post variable there and all will be well (as far as i can tell)
   
   }
   
   add_filter('thematic_post', 'childtheme_excerpts');

   i've tweaked it out a little for my own needs, but the above is the heart of what i was going for. if there is a more tag present it will display the full content up to said tag... if there is no more tag it will present the standard thematic excerpt.

   enjoy!

   I found this incredibly helpful and wanted to give you props. I've looked through the forum for days and this code ended up being the basis for how I customized my child theme. The result is home/category pages that show the teaser (i.e. up to the more tag if present), and then an automatic excerpt if there is no teaser. I also added a second customization to replace the ellipsis after an auto-excerpt with a "read more" link.

   Here's my code in functions.php

   
<?php //Automatic use of teaser or excerpt for home/category pages. Logic from http://themeshaper.com/forums/topic/using-more-tags-preferentially-with-excerpt-fallback
function childtheme_excerpts($content) { //normally i'd call $post here as that is what thematic uses, but that caused problems with the next line
global $thematic_content_length, $post; //needed to declare the standard $post object
if (is_home() || is_front_page()|| is_category()) {
if ( preg_match('/<!--more(.*?)?-->/', $post->post_content ) ) { //here's where i needed to the $post object. didn't seem to work at all with get_the_content()
$content = get_the_content(more_text());
$content = apply_filters('the_content', $content);
$content = str_replace(']]>', ']]>', $content);

   } else {
$content = '';
$content .= get_the_excerpt();
$content = apply_filters('the_excerpt',$content);
}
}
return $content; //send it back to the function. by using $content here i don't monkey with the $post object which was breaking the 'excerpt' and 'full' types. thematic_post will take this variable as the $post variable there and all will be well (as far as i can tell)
}
add_filter('thematic_post', 'childtheme_excerpts');
?>
<?php //If the WordPress automatic "excerpt" is displayed, replace the elipsis with a Read More link
function excerpt_ellipse($text) {
return str_replace('[...]', '...<p>Read More »</p>', $text); }
add_filter('get_the_excerpt', 'excerpt_ellipse');
?>


   Thanks for putting this out there Helga!
