ThemeShaper Forums Topic: using more tags preferentially with excerpt fallback http://themeshaper.com/forums/ Help In Shaping WordPress Themes en Tue, 21 May 2013 14:50:59 +0000 D.Lo on "using more tags preferentially with excerpt fallback" http://themeshaper.com/forums/topic/using-more-tags-preferentially-with-excerpt-fallback#post-23658 Mon, 31 Oct 2011 16:23:16 +0000 D.Lo 23658@http://themeshaper.com/forums/ 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 <code> <?php //Automatic use of teaser or excerpt for home/category pages.

'" 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 $post variable there and all will be well (as far as i can tell) } add_filter('thematic_post', 'childtheme_excerpts');</code></pre> i've tweaked it out a little for my own needs, but the above is the heart of what i was going for. if there is a more tag present it will display the full content up to said tag... if there is no more tag it will present the standard thematic excerpt. enjoy! helgatheviking on "using more tags preferentially with excerpt fallback" http://themeshaper.com/forums/topic/using-more-tags-preferentially-with-excerpt-fallback#post-19818 Thu, 17 Mar 2011 21:46:01 +0000 helgatheviking 19818@http://themeshaper.com/forums/ thematic_content defines the way that full content pages and excerpts look in thematic. has anybody ever created a different type? i've done that before, but this time i am specifically looking to create a type that first looks for full content before a <more> tag and then failing that autogenerate an excerpt. any thoughts? so for example, i'd first define that i want to use this new 'type' on category pages <pre><code>function childtheme_content($content) { if (is_category()) { $content= 'more'; } return $content; } add_filter('thematic_content', 'childtheme_content');</code></pre> and then hypothetically something like ` function childtheme_more($post){ /* if (has  tag) { $post = content up until more tag; } else { $post = get_the_excerpt(); } */ return $post; } add_filter('thematic_content','childtheme_more');
