У меня есть многостраничная форма.Перейдите на страницу 1, страницу 2, а затем на страницу 3. Нажмите «Обновить» (f5), и форма вернется на страницу 2.
Это с drupal-6.Проблема выглядит примерно так: http://drupal.org/node/1060290.
Раскрытие проблемы с помощью таблицы базы данных form_cache.Обе страницы 1 и 2 данные появляются там.В отладчике PHP выглядит так, как будто новый form_id был создан.то есть.storage_form-1add3819cbea88139679819935a69686 - это ключ в таблице кэша базы данных, а form-bcf9556f57f5352a57dfbba4c2120ee7 - это «form_id» при обновлении.
Как выглядит мой код формы?
Основная функция формы:
function myform_online(&$form_state) {
// $form_state['storage']['step'] keeps track of what page we're on.
// start at step 1 if no storage has been set
if (!isset($form_state['storage']['step'])) {
$form_state['storage']['step'] = 1;
}
// If we are saving the form data we should submit rather than display the details.
// At least look at saving the step.
// Don't lose our old data when returning to a page with data already typed in.
$default_values = array();
if (isset($form_state['storage']['values'][$form_state['storage']['step']])) {
$default_values = $form_state['storage']['values'][$form_state['storage']['step']];
}
switch ($form_state['storage']['step']) {
case 1:
// Your Details
module_load_include('inc', 'join_online', 'includes/step1');
И мы обрабатываем submit:
function join_online_submit($form, &$form_state) {
//Save the values for the current step into the storage array.
//dsm($form_state);
$form_state['storage']['values'][$form_state['storage']['step']] = $form_state['values'];
# ahah - bail.
if ($form_state['ahah_submission']) {
return;
}
// How do we work out if this was a refresh? It currently does start with 1 and think that the step is #2.
//Check the button that was clicked and change the step.
if ($form_state['clicked_button']['#id'] == 'edit-previous') {
$form_state['storage']['step']--;
} elseif ($form_state['clicked_button']['#id'] == 'edit-next') {
$form_state['storage']['step']++;
} elseif ($form_state['clicked_button']['#id'] == 'edit-finish') {
//You should store the values from the form in the database here.
//We must do this or the form will rebuild instead of refreshing.
unset($form_state['storage']);
//Go to this page after completing the form.
$form_state['redirect'] = 'join_online/form/thank-you';
}
}
