 In WordPress 3.3-aortic-dissection and 3.2.1

 get_post_meta is case sensitive on the meta-key

 BUT

 update_post_meta is NOT case sensitive

 Thus If there is a pre-existing meta record with a key in say UPPERCASE,
 then one can issue an update for a lowercase key that one can not then
 fetch as it does not exist - only the uppercase key exists.


 Example Code

 {{{

         $meta = get_post_meta ($post->ID, '_allday');
         if ($meta ) { echo '<br />got lower: '; var_dump($meta);
         }
         $meta = get_post_meta ($post->ID, '_ALLDAY');
         if ($meta ) { echo '<br />got upper: '; var_dump($meta);
         }
         update_post_meta (21, '_allday','Tried to update lowercase');
         $meta = get_post_meta ($post->ID, '_allday');
         if ($meta ) { echo '<br />got lower: '; var_dump($meta);
         }
         else { echo '<br />Tried to get lower but no go';
         }
         $meta = get_post_meta ($post->ID, '_ALLDAY');
         if ($meta ) { echo '<br />Still have upper: '; var_dump($meta);
         }


 }}}



 Output of above:



 got upper: array(1) { [0]=> string(14) "tis the upper." }
 Tried to get lower but no go
 Still have upper: array(1) { [0]=> string(25) "Tried to update lowercase"
 }
