你可以安装lightbox2，借助 它，通过用lightbox2的lightmodal，实现弹出的表单。

这里顺便给出做表单的方法：

1，通过 hook_menu 创建地址

<?php
function MYMODULE_menu() {
  $items[] = array();

  $items['MY/URL'] = array(
    'page callback' => 'drupal_get_form',
    'page arguments' => array('MYCALLBACK_form'),
    'type' => MENU_CALLBACK,
    'title' => t('MY TITLE')
  );

  return $items;
}
?>

2，创建form

<?php
function MYCALLBACK_form($form_state) {
  $form = array();

  // add your form elements here. for example:
  $form['MYTEXTFIELD'] = array(
    '#type' => 'textfield',
    '#title' => t('MY TEXT FIELD'),
  );

  // add submit button
  $form['submit'] = array(
    '#value' => 'Submit',
    '#type' => 'button'
  );

  // add cancel button
  // NOTE: the cancel button simply closes the lightbox window
  $form['cancel'] = array(
    '#value' => 'Cancel',
    '#type' => 'button',
    '#attributes' => array(
      'onClick' => "Lightbox.end('forceClose'); return false;"
    )
  );

  return $form;
}
?>

3，使用lightbox

<?php
// NOTE: you should use the l() function here to properly generate your A tag
$page_contents .= '<a href="/MY/URL" rel="lightmodal">MY LINK TEXT</a>';
?>

Ajax返回

<?php
function MYCALLBACK_form($form_state) {
  // ...code...
  $form['#attributes'] = array(
    'onsubmit' => 'return my_js_submit_function(this);'
  );
  // ...code...
}
?>

定义一个javascript函数来验证和使用AJAX提交表单。

function my_js_submit_function(whichThis) {
  // validate your form here

  // define arguments to pass to ajax page callback
  // you'll actually want to collect the user submitted form data here
  var args = {
    myArg1: 'blah',
    myArg2: 'blah',
  };

  // submit the data using jQuery
  // in this case, I'm using the getJSON function which uses GET and expects a JSON object in return
  $.getJSON('/MY/URL/SUBMIT', args,
    function(json){
      // check for a return status, show a message, close the lightbox window, etc
      alert(json.message);
      if (json.status == true) {
        Lightbox.end('forceClose');
      }
    }
  );
}

需要一个最终页面的回调，并且增加义工菜单项来处理AJAX

<?php
function MYMODULE_menu() {
  // ...code...
  $items['MY/URL/SUBMIT'] = array(
    'page callback' => 'MYMODULE_CALLBACK_SUBMIT',
    'type' => MENU_CALLBACK,
  );
  // ...code...
}

function MYMODULE_CALLBACK_SUBMIT() {
  // 1. validate $_GET (not shown, use your imagination)
  // 2. process $_GET (not shown, use your imagination)
  // 3. return a JSON object

  // create return object
  $returnO = new StdClass();
  $returnO->status = true;
  $returnO->message = 'MY INFORMATIVE MESSAGE HERE';

  // output json result
  print drupal_json($returnO);

  // NOTE: if you don't die here, then the theme will be processed. we only want to return a JSON object
  die;
}
?>

最后,我们得到的是一个链接,打开了一个lightbox窗口,包含一个表单,是通过ajax提交。

<?php
if ($title) print "<h1>$title</h1>";
if ($messages) print $messages;
if ($help) print $help;
if ($content) print $content;
?>
