Question

我无法从多步骤表单中获取值以插入数据库。我得到的只是每个字段的空值。

以下是代码：

  function multistep_profile_menu() {
  $items['multistep_profile'] = array(
 'title' => t('Multistep Profile'),
 'page callback' => 'drupal_get_form',
 'page arguments' => array('multistep_profile'),
 'type' => MENU_NORMAL_ITEM,
 'access arguments' => array('access content'),
 );
 return $items;
 }



 function multistep_profile(&$form_state) {
 // $form_state['storage']['step'] keeps track of what page we're on.
 if (!isset($form_state['storage']['step'])) {
 $form_state['storage']['step'] = 1;
 }

 //stores form data and carries it between steps
 $default_value = '';
 if (isset($form_state['storage']['values'][$form_state['storage']['step']])) {
  $default_value = $form_state['storage']['values'][$form_state['storage']['step']];
 }

 switch ($form_state['storage']['step']) {
 // Step 1 of Form
 case 1:
  $form['step_one'] = array(
    '#title' => t('Step 1'),
    '#type' => 'fieldset',
    '#description' => t('Just getting started.'),

  );
  // Full Name
  $form['step_one']['full_name'] = array(
    '#title' => t('Full Name'),
    '#type' => 'textfield',
    '#description' => t('Please enter your name.'),
    '#required' => TRUE,
    '#default_value' => isset($default_value['full_name']) ? $default_value['full_name'] :       '',

  );

  // College/University/Organization
  $form['step_one']['college'] = array(
    '#type' => 'textfield',
    '#title' => t('College/University/Organization'),
    '#default_value' => isset($default_value['college']) ? $default_value['college'] : '',
  );

  // Academic Disciplines
  $form['step_one']['academic'] = array(
    '#type' => 'textfield',
    '#title' => t('Academic Disciplines'),
    '#default_value' => isset($default_value['academic']) ? $default_value['academic'] : '',
    );
  break;

// Step 2 of Form
case 2:
  $form['step_two'] = array(
    '#title' => t('Step 2'),
    '#type' => 'fieldset',
    '#description' => t('Almost done.'),
  );

  // Job Title
  $form['step_two']['job_title'] = array(
    '#title' => t('Job Title'),
    '#type' => 'textfield',
    '#description' => t('Please enter your job title.'),
    '#default_value' => isset($default_value['job_title']) ? $default_value['job_title'] : '',
  );

  // Department
  $form['step_two']['department'] = array(
    '#type' => 'textfield',
    '#title' => t('Department'),
    '#default_value' => isset($default_value['department']) ? $default_value['department'] : '',
  );
  break;
// Step 3 of Form  
case 3:
  $form['step_three'] = array(
    '#title' => t('Step 3'),
    '#type' => 'fieldset',
    '#description' => t('Almost done, part 3.')
  );
  // Q1
  $form['step_three']['q1'] = array(
    '#title' => t('Why do you want to develop a globally networked course?'),
    '#type' => 'textarea',
    '#description' => t(''),

  );
  break;
//Confirmation  
case 4:
  $form['thanks'] = array(
    '#value' => '<p>'. t('Your Profile is complete.') .'</p>',
  );
  break;
  }

  //programmatically display buttons
 if ($form_state['storage']['step'] > 1) {
  $form['previous'] = array(
  '#type' => 'submit',
  '#value' => t('<< Previous'),
  );
 }
 if ($form_state['storage']['step'] != 4) {
 $form['next'] = array(
  '#type' => 'submit',
  '#value' => t('Continue >>'),
 );
 }
 else {
 $form['finish'] = array(
  '#type' => 'submit',
  '#value' => t('Finish'),
 );
 }
  return $form;
  }


 function multistep_profile_submit($form, &$form_state) {
 //Save the values for the current step into the storage array.
 $form_state['storage']['values'][$form_state['storage']['step']] = $form_state['values'];

 //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.


 dpm($form_state);
 // INSERT into DB

 $full_name = $form_state['values']['full_name'];
 $college = $form_state['values']['college']; 
 $academic = $form_state['values']['academic']; 
 $job_title = $form_state['values']['job_title'];
 $department = $form_state['values']['department'];
 $q1 = $form_state['values']['q1'];

 db_query("INSERT INTO {multistep_profile} (full_name, college, academic, job_title,    department, q1, created) VALUES
    ('%s', '%s', '%s', '%s', '%s', '%s', %d)", $full_name, $college, $academic, $job_title, $department, $q1, time());
  drupal_set_message(t('Your profile has been saved.'));


unset($form_state['storage']);

//Go to this page after completing the form.
//$form_state['redirect'] = 'node';
 }
 }

进入数据库的唯一值是“已创建”日期时间戳。

我运行了一个DPM来检查这些值是否在表单步骤之间进行，并且它们是，我只是无法弄清楚如何将它们插入到数据库中。有什么帮助吗？

查看您的提交功能，您（正确）存储在$form_state['storage']['values'][<step_number>]下的不同步骤上收集的值。这与您发布的DPM输出相匹配，即值显示在$form_state['storage']['values'][1]...，$form_state['storage']['values'][2]...等下。

但是在最终的提交处理中，您尝试在$form_state['values'][...]下访问它们，就像这是一个单步表单一样。由于您的最后一步没有发布任何值，因此您将找不到任何值。

所以看起来你只需要改变你的最终值集合逻辑来从你之前放置它们的存储（子）数组中获取值：）

E.g：

$full_name = $form_state['values']['full_name'];

需要

$full_name = $form_state['storage']['values'][1]['full_name'];

等等其他值。
