form_cache

Tyny form cache handler module to turn off form submission while it is rendering to put then to i.e. an AJAX popup window.

Using: just call

form_cache_disable_cache_input($form_build_id);

        // It will prepare new form and put it into cache then.
        $build = entity_view($entity_type, $entities, $view_mode);
        $content = render($build);

        // Restore switcher position to enable form input processing.
        form_cache_enable_cache_input();

and add it to a form element by i.e. 'hook_form_BASE_FORM_ID_alter()'

    $form['#process'][] = 'form_cache_process_input_switch';
