10724,Cannot change excerpt_length using codex example,jsherk,,"Putting this code below (per codex) in the themes functions.php file does not make any difference to excerpt length (stays at 55 no matter what):
function new_excerpt_length($length) {
  return 20;
}
add_filter('excerpt_length', 'new_excerpt_length');

Looking at the changes made in formatting.php, this line:
$excerpt_length = apply_filters('excerpt_length', 55);
appears that it will ALWAYS return 55 no matter what you set your add_filter too... this line is essentially the same as:
$excerpt_length = 55;
so you cannot modify it even with an add_filter call.",defect (bug),closed,normal,2.8.5,General,2.8.4,normal,invalid,"excerpt_length, excerpt length",sorich87
