php - Add body class wordpress error -


i´m using code add class body depending on page:

    <?php      // add custom body class     add_action( 'body_class', 'ilwp_add_my_bodyclass');     function ilwp_add_my_bodyclass( $classes ) {         if ( is_page( '12' ))             {                 $classes[] = 'login';                 return $classes;             }         else if ( is_page( '9' ))             {                 $classes[] = 'homepage';                 return $classes;             }        }      ?>

it works when i´m navigating thru static pages, when go single post error:

warning: join() [function.join]: invalid arguments passed in /users/diego/sites/bb/wp-includes/post-template.php on line 389 class="">

any idea why happening?

you forgot 'else' statement. let 'return' out of if-else statement. maybe need this:

<?php add_action( 'body_class', 'ilwp_add_my_bodyclass'); function ilwp_add_my_bodyclass( $classes ) {     if ( is_page( '12' ))         {             $classes[] = 'login';          }     else if ( is_page( '9' ))         {             $classes[] = 'homepage';         }        return $classes } ?>

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
