Drupal：如何在表格的相同页面上渲染表单的结果 [英] Drupal: How to Render Results of Form on Same Page as Form

问题描述

相关的hook_menu：

$ b如何在表单本身的同一页面上打印表单提交的结果？ $ b

  $ items ['admin / content / ncbi_subsites / paths'] = array（
'title'=>'Paths'，
'description '=>'特定子网站的路径'，
'页面回调'=>'ncbi_subsites_show_path_page'，
'访问参数'=>数组（'管理站点配置'），
'type'=> MENU_LOCAL_TASK，
）; 
  

页面回调：

 函数ncbi_subsites_show_path_page（）{
 $ f = drupal_get_form（'_ nc​​bi_subsites_show_paths_form'）; 
 return $ f; 
} 
  

表单建立功能：

 函数_ncbi_subsites_show_paths_form（）{
 //这里的一堆代码
 
 $ form ['subsite'] = array（
' #title'=> t（'Subsites'），
'#type'=>'select'，
'#description'=>'选择子网站以获取路径'，
'#default_value'=>'选择子网站'，
'#options'=> $ tmp，
）; 
 
 $ form ['showthem'] = array（
'#type'=>'submit'，
'#value'=>'显示路径'，
'#submit'=> array（'ncbi_subsites_show_paths_submit'），
）; 
 
 return $ form; 
} 
  

提交功能（略过跳过验证功能）

  function ncbi_subsites_show_paths_submit（& $ form，& $ form_state）{
 // dpm（$ form_state）; 
 $ subsite_name = $ form_state ['values'] ['subsite']; 
 $ subsite = new Subsite（$ subsite_name）; //我在本模块内部使用的类
 $ paths = $ subsite-> normalized_pa​​ths; 
 
 //构建列表
 $ list = theme_item_list（$ paths）; 
} 
  

如果我打印$ list变量，那就是我想要的，但是我不知道如何使用从ncbi_subsites_show_path_page构建的原始表单页面进入页面。任何帮助非常感谢！

解决方案

Nikit发布的链接中的关键信息是$ form_state ['rebuild']。以下是Drupal 7文档中的一些信息，我相信对于Drupal 6应用相同的方法。

$ form_state ['rebuild']：通常整个
表单处理完成后，
提交处理程序运行，一个表单是
，被认为是要完成的，
drupal_redirect_form（）将把
重定向到一个新页面使用GET
请求（因此浏览器刷新不会
重新提交表单）。但是，如果
'rebuild'设置为TRUE，则
新的表单副本立即被
内置并发送到浏览器;而是
的重定向。这用于
多步骤表单，例如向导和
确认表单。另外，如果一个表单
验证处理程序将'rebuild'
设置为TRUE，并且发生验证错误
，那么该表单在被返回之前被重新生成
，使能窗体
要更改的元素，适当的
到特定的验证错误。

How would I print the results of a form submission on the same page as the form itself?

Relevant hook_menu:

    $items['admin/content/ncbi_subsites/paths'] = array(
        'title' => 'Paths',
        'description' => 'Paths for a particular subsite',
        'page callback' => 'ncbi_subsites_show_path_page',
        'access arguments' => array( 'administer site configuration' ),
        'type' => MENU_LOCAL_TASK,
    );

page callback:

function ncbi_subsites_show_path_page() {
  $f = drupal_get_form('_ncbi_subsites_show_paths_form');
  return $f;
}

Form building function:

   function _ncbi_subsites_show_paths_form() {
      // bunch of code here

      $form['subsite'] = array(
        '#title' => t('Subsites'),
        '#type' => 'select',
        '#description' => 'Choose a subsite to get its paths',
        '#default_value' => 'Choose a subsite',
        '#options'=> $tmp,
      );

      $form['showthem'] = array(
        '#type' => 'submit',
        '#value' => 'Show paths',
        '#submit' => array( 'ncbi_subsites_show_paths_submit'),    
      );

      return $form;
    }

Submit function (skipped validate function for brevity)

function ncbi_subsites_show_paths_submit( &$form, &$form_state ) {
  //dpm ( $form_state );
  $subsite_name = $form_state['values']['subsite'];
  $subsite = new Subsite( $subsite_name ); //y own class that I use internally in this module
  $paths = $subsite->normalized_paths;

  // build list
  $list = theme_item_list( $paths );
}

If I print that $list variable, it is exactly what I want, but I am not sure how to get it into the page with the original form page built from 'ncbi_subsites_show_path_page'. Any help is much appreciated!

解决方案

The key information in the link Nikit posted is $form_state['rebuild']. Here's some info from Drupal 7 documentation that I believe applies the same for Drupal 6...

$form_state['rebuild']: Normally, after the entire form processing is completed and submit handlers ran, a form is considered to be done and drupal_redirect_form() will redirect the user to a new page using a GET request (so a browser refresh does not re-submit the form). However, if 'rebuild' has been set to TRUE, then a new copy of the form is immediately built and sent to the browser; instead of a redirect. This is used for multi-step forms, such as wizards and confirmation forms. Also, if a form validation handler has set 'rebuild' to TRUE and a validation error occurred, then the form is rebuilt prior to being returned, enabling form elements to be altered, as appropriate to the particular validation error.
