Register Action


See also:
Documentation: RegisterActionInfo.
This is the development page for the Register action.
 


I've started working on a new version of an action for user registration. The motivation behind this is to replace the current usersetting action with three distinct actions:



The code


Save the following as ./actions/register.php and use it as {{register}}.

  1. <?php
  2. /**
  3.  * Display a form for user registration.
  4.  *
  5.  * This action allows new users to register an account, if user registration is enabled.
  6.  * All the required fields are validated before the new user is created.
  7.  *
  8.  * @package     Actions
  9.  * @name        Register
  10.  *
  11.  * @author      {@link http://wikka.jsnx.com/DarTar Dario Taraborelli}
  12.  * @version     0.1
  13.  * @since       Wikka 1.1.X.X
  14.  *
  15.  * @todo
  16.  *          - (optionally) drop WikiName restriction on usernames;
  17.  *          - use core functions to validate fields;
  18.  *          - add done/failed icons for each field after form is posted;
  19.  *          - use central error handler for printing error messages;
  20.  *          - define strategy to link hardcoded login/logout page;
  21.  *          - define welcome page where new users must be redirected;

Try to use SemanticMarkup if this is going to be rewritten anyway, instead of:
$form .= '<tr>';
$form .= '	<td align="right">Confirm password:</td>';
$form .= '	<td><input type="password" name="confpassword" size="40" title="Type again your password for confirmation" /></td>';
$form .= '</tr>';

use:
$form .= '<label>Confirm password:<input type="password" name="confpassword" size="40" title="Type again your password for confirmation" /></label>';


It is more elegant, semantically clean and frees some bytes to run free in forests! --IanAndolina
