我正在开发一个Drupal6模块,我想根据保存在数据库中的数据生成一个表,其中每行都有复选框。表格生成得很好,但是复选框并没有在表格中呈现,而是将它们的节点id放在表格下面。如下截图所示:

"21“是”测试题01“的节点id,"19”是“测试题02”的节点id。
我正在使用的代码(是的,它都在一个主题函数中,这不是很理想。我计划在复选框问题解决后移动东西):
function theme_qt_assignment_questions_table($form) {
// Get the questions from the database
$db_results = db_query('SELECT {qt_questions}.nid, title, lesson, unit FROM node INNER JOIN {qt_questions} on {node}.nid = {qt_questions}.nid WHERE lesson = %d AND unit = %d',
$form['#lesson'], $form['#unit']);
// Define the headers for the table
$headers = array(
theme('table_select_header_cell'),
array('data' => t('Title'), 'field' => 'title'/*, 'sort' => 'asc'*/),
array('data' => t('Lesson'), 'field' => 'lesson'),
array('data' => t('Unit'), 'field' => 'unit'),
);
while($row = db_fetch_object($db_results)) {
$checkboxes[$row->nid] = '';
$form['nid'][$row->nid] = array(
'#value' => $row->nid
);
$form['title'][$row->nid] = array(
'#value' => $row->title
);
$form['lesson'][$row->nid] = array(
'#value' => $row->lesson
);
$form['unit'][$row->nid] = array(
'#value' => $row->unit
);
}
$form['checkboxes'] = array(
'#type' => 'checkboxes',
'#options' => $checkboxes,
);
// Add the questions to the table
if(!empty($form['checkboxes']['#options'])) {
foreach(element_children($form['nid']) as $nid) {
$questions[] = array(
drupal_render($form['checkboxes'][$nid]),
drupal_render($form['title'][$nid]),
drupal_render($form['lesson'][$nid]),
drupal_render($form['unit'][$nid]),
);
}
} else {
// If no query results, show as such in the table
$questions[] = array(array('data' => '<div class="error">No questions available for selected lesson and unit.</div>', 'colspan' => 4));
}
// Render the table and return the result
$output = theme('table', $headers, $questions);
$output .= drupal_render($form);
return $output;

事实证明,我试图简化这个问题,实际上就是这个问题。也就是说,用hook_theme做所有的事情都是不正确的。相反,我定义了一个函数,它从数据库中提取信息,创建checkboxes数组并在hook_form中调用它,如下所示:
$form['questions_wrapper']['questions'] = _qt_get_questions_table($node->lesson, $node->unit);在此函数(_qt_get_questions_table())的末尾,我指定了主题函数,该函数将所有内容放入表中:
$form['#theme'] = 'qt_assignment_questions_table'; 我仍然是Drupal的新手,所以对于有同样问题的人来说,这个解释可能不是最好的,但希望它能有所帮助。
