如何单独显示更改密码表单？

我需要将用户的密码重置表单放置在用户编辑页面上下文之外的区域中。

这个“ 更改密码”模块看起来很有希望。但是，它仅适用于drupal 6，并且仅提供开发快照。

我可以使用hook_form_alter来隐藏编辑用户表单上与用户密码无关的字段，但是如果可能的话，我不希望这样做。

我希望此功能已经存在。

提前致谢。

我现在还找不到任何东西，这听起来很方便，所以这里有一个小模块，提供了一个带有更改密码形式的块：

文件：change_password.info

name = Change Password
description = Provides a block containing a form for the current user to change their password.
core = 7.x

文件：change_password.module

<?php

/**
 * Implements hook_block_info().
 */
function change_password_block_info() {
  return array(
    'change_password_form' => array(
      'info' => t('Change Password Form')
    )
  );
}

/**
 * Implements hook_block_view().
 */
function change_password_block_view($delta = '') {
  $block = array();
  // Only show the block for a logged-in user.
  if ($delta == 'change_password_form' && user_is_logged_in()) {
    $block['subject'] = t('Change Password');
    $block['content'] = drupal_get_form('change_password_form');
  }
  return $block;
}

/**
 * Password change form.
 */
function change_password_form($form, &$form_state) {
  // Sanity check
  if (user_is_anonymous()) {
    return $form; // Or drupal_access_denied()?
  }

  // Get the currently logged in user object.
  $form['#account'] = $GLOBALS['user'];

  // Textfield cor current password confirmation.
  $form['current_pass'] = array(
    '#type' => 'password',
    '#title' => t('Current password'),
    '#size' => 25,
    '#required' => TRUE
  );

  // Password confirm field.
  $form['account']['pass'] = array(
    '#type' => 'password_confirm',
    '#size' => 25,
    '#title' => t('New Password'),
    '#required' => TRUE
  );

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Submit')
  );

  return $form;
}

/**
 * Validate handler for change_password_form().
 */
function change_password_form_validate(&$form, &$form_state) {  
  // Make sure the password functions are present.
  require_once DRUPAL_ROOT . '/' . variable_get('password_inc', 'includes/password.inc');

  // Make sure the provided current password is valid for this account.
  if (!user_check_password($form_state['values']['current_pass'], $form['#account'])) {
    form_set_error('current_pass', t('The current password you provided is incorrect.'));
  }
}

 /**
 * Submit handler for change_password_form().
 */
function change_password_form_submit(&$form, &$form_state) {
  // Set up the edit array to pass to user_save()
  $edit = array('pass' => $form_state['values']['pass']);

  // Save the account with the new password.
  user_save($form['#account'], $edit);

  // Inform the user.
  drupal_set_message(t('Your password has been changed.'));
}

它（经过了轻微的测试）可以正常工作，但是您可能想要一次让自己安心使用。

更新我已经把它作为一个沙箱项目，以防万一有人感兴趣。

这是另一种方法。

在我的示例中，我渲染了内置的user_profile_form()，并简单地取消设置了不必要的字段。很好，因为这样可以调用Drupal自己的验证函数，还可以呈现基于JavaScript的密码强度和密码匹配指示器，并且字段标签和描述与用户编辑表单上的相同（除了这里我取出了e -mail更改文本），但也可以根据需要进行更改。

结果将如下所示：

这种形式将在example.com/change-password路径上可见（当然，example.com应替换为您的域），并且我还将为其定义一个块。

/**
 * Implements hook_menu().
 */
function YOURMODULENAME_menu() {
    $items = array();

    $items['change-password'] = array(
      'title' => t('Change password'),
      'description' => t('You can change your password here.'),
      'page callback' => 'YOURMODULENAME_render_user_pass_change_form',
      'access arguments' => array('access content'),
    );

    return $items;
}

/**
 * Render the password changing form with the usage of Drupal's built-in user_profile_form
 * 
 * @global type $user
 * @return array The rendered form array for changing password
 */
function YOURMODULENAME_render_user_pass_change_form() {

    global $user;

    if (!user_is_logged_in()) {
        drupal_access_denied();
    }

    module_load_include('inc', 'user', 'user.pages');
    $form = drupal_get_form('user_profile_form', $user);

    $request_new = l(t('Request new password'), 'user/password', array('attributes' => array('title' => t('Request new password via e-mail.'))));
    $current_pass_description = t('Enter your current password to change the %pass. !request_new.', array('%pass' => t('Password'), '!request_new' => $request_new));

    $form['account']['current_pass']['#description'] = $current_pass_description;    

    unset(
      $form['account']['name'],
      $form['account']['mail'],
      $form['account']['status'],
      $form['account']['roles'],
      $form['locale'],
      $form['l10n_client'],
      $form['picture'],
      $form['overlay_control'],
      $form['contact'],
      $form['timezone'],
      $form['ckeditor'],
      $form['metatags'],
      $form['redirect']
      );

    return $form;
}

define('PASSWORD_CHANGING_BLOCK', 'password_changing_block');

/**
 * Implements hook_block_info().
 */
function YOURMODULENAME_block_info() {

    $blocks = array();

    $blocks[PASSWORD_CHANGING_BLOCK] = array(
      'info' => t('Block for changing password'), //The name that will appear in the block list.
      'cache' => DRUPAL_CACHE_GLOBAL, // The block is the same for every user on every page where it is visible.
    );

    return $blocks;
}

/**
 * Implements hook_block_view().
 * 
 * Prepares the contents of the block.
 */
function YOURMODULENAME_block_view($delta = '') {

    switch ($delta) {
        case PASSWORD_CHANGING_BLOCK :
            if(user_is_logged_in()){
                $block['subject'] = t('Change Password');
                $block['content'] = drupal_get_form('YOURMODULENAME_render_user_pass_change_form');                
            }
            break;
    }
    return $block;
}

当然，请YOURMODULENAME用您自己的模块名称替换（甚至'page callback'在调用时drupal_get_form）。您也可以根据需要取消设置其他字段（例如，通过其他模块渲染更多字段）。
将缓存放入代码后，将其清除。

之后，您只需调用即可呈现此表单drupal_get_form('YOURMODULENAME_render_user_pass_change_form');。
