If you are a plugin developer, you should be aware of the new update system that is being integrated into GetSimple 3.1. Starting with this release, the GetSimple installation will now notify a user when a new version of that particular plugin is available for download within Extend. These steps will help you as a developer to ensure that your plugin is compatible with this new process.

Определение версии GetSimple – не такая простая задача, так как единственная доступная функция return_site_ver(), выводящая на экран номер версии в GS 2.03 и возвращающая результат в версии 3.0b уже устарела (прим. переводчика – пометка о том, что данная функция устарела в списке тэгов англоязычной Вики отсутствует). Самый простой способ определить, установлен ли плагин под GetSimple 2.03 или 3.0+, пожалуй, следующий:

$isV3 = function_exists('get_site_version');

Самый правильный способ определения версии – следующий (используйте его только внутри функций, чтобы не засорять глобальное пространство имен!):

include(GSADMININCPATH.'configuration.php');
$version = GSVERSION;

To trigger a function myplugin_function on page deletes in GetSimple 2.03 and 3.0+ use the following code:

// GetSimple 3.0+
add_action('page-delete', 'myplugin_function'); 

// GetSimple 2.03
if (!function_exists('get_site_version') && basename($_SERVER['PHP_SELF']) == 'deletefile.php') {
  myplugin_function();
}

This describes how to display messages in back-end plugin pages. Assume you have 3 variables, $isSuccess, $canUndo and $msg holding the message. To display the message for your plugin myplugin, add the following code to your plugin:

<?php 
  if (isset($msg)) {
    if ($canUndo) $msg .= ' <a href="load.php?id=myplugin&undo">' . i18n_r('UNDO') . '</a>' 
?>
<script type="text/javascript">
  $(function() {
    $('div.bodycontent').before('<div class="<?php echo $isSuccess ? 'updated' : 'error'; ?>" style="display:block;">'+
            <?php echo json_encode($msg); ?>+'</div>');
    $(".updated, .error").fadeOut(500).fadeIn(500);
  });
</script>
<?php 
  } 
?>

The publication date in the page XML files is stored in an english text format, which can be converted to a UNIX timestamp with

$timestamp = strtotime($data->pubDate);

GetSimple itself uses the date function to display dates, which will work with other languages only when no weekday or month names are displayed, as these will always be in english.

To display a truly localized date, use:

$dateLocale = 'de_DE,de,ger,deu';      // or use $LANG or a setting in your plugin, 
                                       // for OS compatibility multiple locales should be possible
$dateFormat = "%A, %d.%m.%Y - %H:%M";  // should be a entry in the i18n language file of your plugin
                                       // for the format see PHP function strftime
$oldlocale = setLocale(LC_TIME, '0');  // save old locale
setlocale(LC_TIME, preg_split('/s*,s*/', $dateLocale))
echo strftime($dateFormat, $date);     // $date is a UNIX timestamp
setLocale(LC_TIME, $oldlocale);        // restore old locale

The important cookie is only valid for path /admin. There is no (easy?) way to correct the problem for the frontend. However, if you need it for the backend, e.g. linking to a php somewhere in the plugins folder, you can add the following code to your plugin (e.g. directly after setting up the hooks):

if (!myplugin_is_frontend() && myplugin_gsversion() == '3.0') {
  // workaround for GetSimple 3.0:
  if (isset($_COOKIE['GS_ADMIN_USERNAME'])) setcookie('GS_ADMIN_USERNAME', $_COOKIE['GS_ADMIN_USERNAME'], 0, '/');
}

function myplugin_is_frontend() {
  return function_exists('get_site_url');
}

function myplugin_gsversion() {
  @include(GSADMININCPATH.'configuration.php');
  return GSVERSION;
}
