[wp-hackers] Admin notices

[John 3:16 Media]

That is useful for turning 4 lines of code into one, but still a paint to
type for each message.  I make it easier with this function in each of my
plugins:

if (!function_exists('_adminmsg')) {
 // A function to hook into admin_notices and either display an updated or
error message.
  function _adminmsg($msg, $type = 'msg') {
  if (!isset($msg)) {
   // No message was set, no point in displaying an empty notice box
   return false;
  }

  if (($type === 'msg') || ($type === 'message')) {
   add_action('admin_notices', create_function('', 'echo \'<div id="message"
class="updated"><p>' . $msg . '</p></div>\';'));
   return true;
  }

  if (($type === 'err') || ($type === 'error')) {
   add_action('admin_notices', create_function('', 'echo \'<div id="message"
class="error"><p>' . $msg . '</p></div>\';'));
   return true;
  }

  // Not a valid type
  return false;
 }
}

Then I just call _adminmsg('my message here');

The purpose was to reallly make sure I wasn't reinventing someting core
already does, but apparantly not, though I think its useful and should be
part of the plugin API per scribu's comment it dosen't seem like such a
function would make it into core.
