   Hi,I'm converting a blog from Sandbox to thematic and wanting to use the subheading plug-in (http://wordpress.org/extend/plugins/subheading/) which requires this code in the template where the subheading goes:
   

   if (function_exists('the_subheading')) { the_subheading('<p>', '</p>'); }

   This was pretty straight forward in Sandbox by inserting in template.

   So I'm working towards filtering the thematic posttitle function but getting bogged down in the finer details.
   I have this so far:
   

   function childtheme_override_postheader_posttitle() {
   	    if (is_single() || is_page() && (function_exists('the_subheading'))) {
   	        $posttitle = '<h1 class="entry-title">' . get_the_title() . "</h1>\n";
                   $posttitle .= the_subheading('<p class="subh">', '</p>');
   	    } elseif (is_404()) {
   	        $posttitle = '<h1 class="entry-title">' . __('Not Found', 'thematic') . "</h1>\n";
   	    } else {
   	        $posttitle = '<h2 class="entry-title"><a href="';
   	        $posttitle .= apply_filters('the_permalink', get_permalink());
   	        $posttitle .= '" title="';
   	        $posttitle .= __('Permalink to ', 'thematic') . the_title_attribute('echo=0');
   	        $posttitle .= '" rel="bookmark">';
   	        $posttitle .= get_the_title();
   	        $posttitle .= "</a></h2>\n";
   	    }
   	    return $posttitle;
       	}
   add_filter('thematic_postheader_posttitle','childtheme_override_postheader_posttitle');

   which is not throwing up any errors, just not working.
   Tried previous filtering the postmeta with something like this:
   

   if(function_exists('the_subheading')) {
   	   $postmeta = '<div class="entry-meta">';
              $postmeta .= the_subheading('<p class="subh">', '</p>');
              $postmeta .= thematic_postmeta_entrydate();
   	   $postmeta .= thematic_postmeta_editlink();
   	   $postmeta .= "</div><!-- .entry-meta -->\n";
               }

   with some success but for some reason wasn't ending up in the div.

   Pretty sure I'm missing some basic stuff :|

   I'm quite keen to get my head around the workings of the code but not sure where to look for info.
   for instance what does this little baby do:
   

   \n

   ...and what is the difference between
   = and .=

   Can someone point me to a resource where I can nut out those kinds of things?
   Any comments on the filter are also welcome.

   Enjoying thematic & exploring the forum

   Thanks

   you are defo missing some "basics". your first block has you calling the override and then using add_filter... which is crossing your wires. you either use the override OR you add_filter, not both.

   but i think you were closer w/ your 2nd block of code (which i presume was in a function).
   i think filtering will be easiest. i'd prolly filter thematic_postheader.... BUT the issue i "think" (only think b/c i am not looking at the plugin's code) I see is that the plugin ONLY echos out the value when you call the the_subheading() function. to use it with filters you need to return the value instead and idk if the plugin has a get_subheading() function.

   btw- "\n" means that the php will print a new line character (essentially a carriage return). those little things are tough to google.

   Hey Thanks HtV - I'll have to hunt a little harder for an example to work from next time. Starting again! I'll report back when I have some success.
   cheers

   Solution from the plugin author:

   By default the_subheading() function will echo the value, but if you pass a third parameter of false, the value should be returned instead. Try changing it to the following:

   $postmeta = the_subheading('<p>', '</p>', false);

   Did the trick!
