我正在研究一个 Drupal 6 模块,我想从我保存在数据库中的数据中生成一个表,每行中都有复选框。表格生成良好,但复选框未在表格中呈现,而是将其节点 ID 放在表格下方。请看下面的截图:
“21”是“Test Question 01”的节点id,“19”是“Test Question 02”的节点id。
我正在使用的代码(是的,它都在一个不理想的主题函数中。我计划在解决复选框问题后移动东西):
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;
}
