My form, lets call it organize_issue, is a form in a custom module being called from the menu using the page callback drupal_get_form function. The form works perfectly well.

I'm trying to implement some AHAH type functionality now, and need to get the page from cache using form_get_cache($form_build_id, $form_state) but, oddly enough, my form isn't being cached. Ever. Other forms on the site are, just not this one. As I said the form works fine, and submits and validates and whatnot... it just never caches. Is their something simple I'm missing?

我的表，我们叫它organize_issue，在自定义的模块被称为从使用页面回调菜单形式drupal_get_form功能。非常好的形式。

我试图实施某些类型的功能和效果，现在，需要把页面缓存使用form_get_cache($form_build_id, $form_state)但是，奇怪的是，我没有被缓存。曾经。网站上的其他形式的，不是这一个。正如我所说的形式，做工精细，并提出和验证和诸如此类的东西…它只是没有缓存。是他们的简单的东西我失踪？

In your function that builds the form you should have a value setting the form to cache...

Should look some thing like '#cache' => TRUE, if you don't see it that might be why your form isn't caching...you should be building your form on a way that the array of the form sets it to cache:

<?php
  function _organize_issue_form($node) {
    global $user;

 $form = array(
   '#theme' => 'organize_issue',
   '#cache' => TRUE,
 );
?>

HTH

在你的函数，建立了你应该有一个值设置窗体缓存形式…

看起来一样'#cache' => TRUE，如果你没有看到它，可能是为什么你不能缓存……你应该的方式形成阵列设置缓存建立你的形式：

<?php
  function _organize_issue_form($node) {
    global $user;

 $form = array(
   '#theme' => 'organize_issue',
   '#cache' => TRUE,
 );
?>
