Suppressing the title in templates for all posts in the “blurb” category:
function suppress_if_blurb( $title, $id = null ) { if ( in_category(' blurb', $id ) ) { return ''; } return $title; } add_filter( 'the_title', 'suppress_if_blurb', 10, 2 );Note the addition of
nullas the default value for the$idvariable. This is because some instances of the usage of this filter did not supply a post ID. This inconsistency was introduced in version 3.1, and fixed in version 3.3 (see ticket #16688). If you want to be compatible with these older versions, you need to supply the default value as above, or you will end up with a PHP warning stating that you are missing an argument. If you don’t need to support 3.1 or 3.2, it isn’t necessary to specify a default value for$id.
