   On my main index page, each post has a category link.

   My Categories are locations in Canada with provinces being the parents and cities being the children.

   Is there a way to make the category ALWAYS display like "$child, $parent" every time?

   Currently the order changes based on alphabetizing, for instance "Alberta, Lethbridge" ($parent, $child) and "Brandon, Manitoba" ($child, $parent)

   thanks

   OK I managed to figure it out on my own.

   First, in loop.php, the function get_the_category_list(); has to have the $parents parameter set to "multiple". (e.g. get_the_category_list(', ', multiple);

   Then in wp-includes/category-template.php I modified these lines in the function get_the_category_list();

   From:

   else {
   $i = 0;
   foreach ( $categories as $category ) {
   if ( 0 < $i )
   $thelist .= $separator;
   switch ( strtolower( $parents ) ) {
   case 'multiple':
   if ( $category->parent )
   $thelist .= get_category_parents( $category->parent, true, $separator );
   $thelist .= 'term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" ' . $rel . '>' . $category->name.'';
   break;
   case 'single':
   $thelist .= 'term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" ' . $rel . '>';
   if ( $category->parent )
   $thelist .= get_category_parents( $category->parent, false, $separator );
   $thelist .= "$category->name";
   break;
   case '':
   default:
   $thelist .= 'term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" ' . $rel . '>' . $category->name.'';
   }
   ++$i;
   }
   }

   To:

   else {
   $i = 0;
   foreach ( $categories as $category ) {
   if ( 0 < $i )
   $thelist .= $separator;
   switch ( strtolower( $parents ) ) {
   case 'multiple':
   if ( $category->parent )
   //changed by me
   $thelist .= 'term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" ' . $rel . '>' . $category->name.''.$separator;
   $thelist .= get_category_parents( $category->parent, true,'');
   //end change
   break;
   case 'single':
   $thelist .= 'term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" ' . $rel . '>';
   if ( $category->parent )
   $thelist .= get_category_parents( $category->parent, false, $separator );
   $thelist .= "$category->name";
   break;
   case '':
   default:
   $thelist .= 'term_id ) . '" title="' . esc_attr( sprintf( __( "View all posts in %s" ), $category->name ) ) . '" ' . $rel . '>' . $category->name.'';
   }
   ++$i;
   }
   }
