Step 4: Creating a Form
Form rendering and validation:
<?php
/* Load libraries. */
require_once MOPPLE_BASE . '/lib/base.php';
require_once MOPPLE_BASE . '/lib/MP3Form.php';
require_once 'Horde/Variables.php';
/* Initialize variables. */
$variables = &Variables::getDefaultVariables();
$id = $variables->get('id');
$edit = !empty($id);
$title = $edit ? _("Edit MP3") : _("Add MP3");
/* Create form instance. */
$form = &new MP3_Form($variables, $title);
/* Validate form submission. */
if ($form->validate($variables)) {
/* The form was submitted and had valid data. */
require_once MOPPLE_BASE . '/lib/Driver.php';
$driver = &Mopple_Driver::singleton($conf['storage']['driver']);
$id = $driver->add($variables->get('song_title'),
$variables->get('song_artist'),
$variables->get('song_album'));
if (is_a($id, 'PEAR_Error')) {
$notification->push($id, 'horde.error');
} else {
$message = $edit ? _("The MP3 \"%s\" has been updated sucessfully.") :
_("The MP3 \"%s\" has been added successfully.");
$notification->push(sprintf($message, $variables->get('song_title')), 'horde.success');
header('Location: ' . Horde::applicationUrl('list.php', true));
exit;
}
}
/* Output HTML. */
require MOPPLE_TEMPLATES . '/common-header.inc';
require MOPPLE_TEMPLATES . '/menu.inc';
$renderer = &$form->getRenderer();
$form->renderActive($renderer, $variables, Horde::selfUrl(), 'post');
require $registry->get('templates', 'horde') . '/common-footer.inc';
?>
