我无法从多步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。

这是代码：

  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';
 }
 }

使其进入数据库的唯一值是“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传递，它们是，我只是不知道如何让它们插入到数据库中。有什么帮助吗？

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

但是在您的最终提交处理中，您尝试在 下访问它们$form_state['values'][...]，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，因此您不会在那里找到任何东西。

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

例如：

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

需要是

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

对于其他值，依此类推。
