我正在努力教自己Drupal,我发现了一些我找不到任何教程的东西。
我正在尝试使用动态数量的文本字段生成表单,以填充和编辑自定义表的内容。在常规PHP中,我将通过以下方式实现此目的:
$count = '0';
while ($row = mysql_fetch_array ($result) {
echo "<input type='text' name='title_row".$count."' value='".$row['title']."'>"
$count = $count +1;
}
有人能指出我会告诉我如何在Drupal中执行此操作(并处理提交的数据)吗?
谢谢

检查forms API reference和Form API Quickstart Guide。
您示例的简单版本如下所示:
/**
* Form builder function - creates definition of form
*/
function yourModule_table_edit_form($form_state) {
$form = array();
// TODO: Add code/query to populate $result, using the
// Drupal DAL functions, e.g.:
$result = db_query('SELECT * FROM {your_table}');
while ($row = db_fetch_array($result) {
// Create one textfield per row
// NOTE: assumes content of title column can be used as an array index
$form[$row['title']] = array(
'#type' => 'textfield',
'#title' => $row['title'],
'#default_value' => $row['value'], // NOTE: Just assumed the column name
'#size' => 60, // Adjust as needed
'#maxlength' => 60, // Adjust as needed
// NOTE: more options for input element definition available - check the API docs
);
}
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Save'),
);
return $form;
}
/**
* Form submit function
*/
function yourModule_table_edit_form_submit($form, &$form_state) {
foreach ($form_state['values'] as $row_title => $value) {
// TODO: Do something with the submitted values
}
}
(注意:未经测试的代码,谨防拼写错误和其他错误)
要准备输出表单,请拨打drupal_get_form('yourModule_table_edit_form')
