ok, that’s great – I’m knee deep in setting up a website for a client, or I’d cut some code for you.
I think the answer is to do it on registration, then they only do it once. Of course whatever method you choose will not stop someone having multiple usernames as long as they have an email address for each, but most will play the game.
So I think you’ll need a combination of the following
This code adds first and last name to the registration, so you should be able to alter it to be for adding the group
/add code for adding first and last name to registration
//1. Add a new form element...
add_action('register_form','myplugin_register_form');
function myplugin_register_form (){
$first_name = ( isset( $_POST['first_name'] ) ) ? $_POST['first_name']: '';
$last_name = ( isset( $_POST['last_name'] ) ) ? $_POST['last_name']: '';
?>
<p>
<label for="first_name"><?php _e('First Name as people call you eg Dave','mydomain') ?><br />
<input type="text" name="first_name" id="first_name" class="input" value="<?php echo esc_attr(stripslashes($first_name)); ?>" size="25" /></label>
</p>
<p>
<label for="last_name"><?php _e('Last Name','mydomain') ?><br />
<input type="text" name="last_name" id="last_name" class="input" value="<?php echo esc_attr(stripslashes($last_name)); ?>" size="25" /></label>
</p>
<?php
}
//2. Add validation. In this case, we make sure first_name is required.
add_filter('registration_errors', 'myplugin_registration_errors', 10, 3);
function myplugin_registration_errors ($errors, $sanitized_user_login, $user_email) {
if ( empty( $_POST['first_name'] ) )
$errors->add( 'first_name_error', __('<strong>ERROR</strong>: You must include a first name.','mydomain') );
if ( empty( $_POST['last_name'] ) )
$errors->add( 'last_name_error', __('<strong>ERROR</strong>: You must include a last name.','mydomain') );
return $errors;
}
//3. Finally, save our extra registration user meta.
add_action('user_register', 'myplugin_user_register');
function myplugin_user_register ($user_id) {
if ( isset( $_POST['first_name'] ) )
update_user_meta($user_id, 'first_name', $_POST['first_name']);
if ( isset( $_POST['last_name'] ) )
update_user_meta($user_id, 'last_name', $_POST['last_name']);
}
This code is the dropdown list from settings, so bits of this is what you’ll need to put in 1. above
global $rpg_groups ;
?>
<table class="form-table">
<tbody>
<tr>
<th><label for="bbp-private-groups"><?php esc_html_e( 'Group', 'private-groups' ); ?></label></th>
<td>
<select name="bbp-private-groups" id="group">
<?php global $rpg_groups ;
if (empty( $rpg_groups ) ) : ?>
<option value=""><?php esc_html_e( '— No groups yet set up —', 'private-groups' ); ?></option>
<?php else : ?>
<?php $private_group = get_user_meta($user_id, 'private_group', true); ?>
<option value="" selected="selected"><?php esc_html_e( '— No group —', 'bbpress' ); ?></option>
<?php endif; ?>
<?php foreach ( $rpg_groups as $group => $details ) : ?>
<option <?php selected( $private_group, $group ); ?> value="<?php echo esc_attr( $group ); ?>"><?php echo $group.' '.$details ; ?></option>
<?php endforeach; ?>
</select>
</td>
</tr>
</tbody>
</table>
<?php
}
Finally the save part that you’ll need to put in 3 above
function bbp_edit_user_rpg( $user_id ) {
$private_group = ( $_POST['bbp-private-groups'] ) ;
// Update town user meta
if ( !empty( $private_group ) )
update_user_meta( $user_id, 'private_group', $private_group);
// Delete town user meta
else
delete_user_meta( $user_id, 'private_group' );
So if you cobble together bits of that, you should be able to get it to work.
If you do, can I ask a big favour, and that is that you paste the results here, it would be useful code for others.
If you fail, come back to me in a week or so, and I’ll see if I can cut something for you
