   I need to access some custom field info before doing get_header() in my various templates (e.g., home.php, page.php, archive.php, etc.), so I've set up the following in functions.php:

   function F_custom_fields() {
   	if (have_posts()) : while (have_posts()) : the_post();
   		$custom_fields = get_post_custom();
   		$page_icon = $custom_fields['eva_page_icon'][0];
   		$div_id = $custom_fields['eva_div_id'][0];
   	endwhile; endif;
   }

   Since this is not working, I figure there is a variable/array/other that I need to set with global $var as the first thing in the function. I just can't figure out what it is.

   I ended up having to go about this another (better) way.

   In functions.php:
   

   function F_custom_fields($need)
   {
           // The Loop all on one line
       if (have_posts()) : while (have_posts()) : the_post(); endwhile; endif;
           // Get all of the custom items from the wp_postmeta table for this post/page
       $custom_fields = get_post_custom();
           // Return the needed custom item, if it exists
       if ($need == 'page_icon')
       {
           $page_icon = $custom_fields['eva_page_icon'][0];
           if (!empty($page_icon))
           {
               return $page_icon;
           }
           else
           {
               return FALSE;
           }
       }
       else if ($need == 'div_id')
       {
           $div_id = $custom_fields['eva_div_id'][0];
           if (!empty($div_id))
           {
               return $div_id;
           }
           else
           {
               return FALSE;
           }
       }
   }

   In header.php:
   

   $begin_div_id = F_custom_fields('div_id');
   if ($begin_div_id)
   {
       echo '<div id="'.$begin_div_id.'">'."\n";
   }

   And in footer.php (to close the div tag started in header.php:
   

   $end_div_id = F_custom_fields('div_id');
   if ($end_div_id)
   {
       echo '</div>';
   }
