I had a very hard time getting post formats to function in my child theme. Finally got them working thanks to my post on WPAnswers - I hope this helps anyone who is having the same/similar issues!
In sum, it seems that the Thematic body class does not include the .format-$format selectors even when post formats have been enabled. I tried child_theme_override_post_class() to remove thematic_post_class but to no avail - although the post_class echoed instead of thematic_post_class and did contain the .format class, the style in the selectors was not read. So, the selector had to be manually added to post_class in functions.php like this:
function my_thematic_post_format_class( $classes = array() ) {
$format = get_post_format();
if ( '' == $format )
$format = 'standard';
$classes[] = 'format-' . $format;
return $classes;
}
add_filter( 'post_class', 'my_thematic_post_format_class' );From what I gathered, Twenty-Ten does it something like this which did not work for me:
function my_add_format_support() {
add_theme_support( 'post-formats', array( 'aside', 'gallery', 'link', 'image') );
}
add_action('after_setup_theme', 'my_add_format_support', 11);Perhaps the .format class should be added to thematic_post_class? And @anyone more experienced than me, is there a better way to do this?
