Drupal Form API - 从数据库填充字段
我希望用数据库中的记录填充 drupals 表单 api 字段。
with：
function mytopfive() {
$form['mytop_header'] = array(
'#type' => 'markup',
'#value' => t('<h2>Your favourite Jobs</h2>'),
);
$result = mysql_query('SELECT * FROM topfive WHERE uid = 1 ORDER BY order_value ASC');
while ($node = db_fetch_object($result)) {
$rid = $node->rid;
$order = $node->order_value;
$title= $node->title;
$form['rid'][$node->rid] = array(
'#type' => 'textfield',
'#size' => 2,
'#maxlength' => 1,
'#default_value' => $rid,
);
$form['job_name'][$node->rid] = array(
'#type' => 'textfield',
'#title' => t('To'),
'#size' => 40,
'#maxlength' => 42,
'#value' => $title,
);
$form['job_order'][$node->rid] = array(
'#type' => 'textfield',
'#size' => 2,
'#maxlength' => 1,
'#default_value' => $order,
);
}
$form['submit'] = array('#type' => 'submit', '#value' => t('Submit'));
return $form;
}
它返回数组。
我觉得答案是 foreach 循环。
非常感谢任何帮助。
Im looking to populate drupals form api fields with records from the database.

);
$result = mysql_query('SELECT * FROM topfive WHERE uid = 1 ORDER BY order_value ASC');
while ($node = db_fetch_object($result)) {
$rid = $node->rid;
$order = $node->order_value;
$title= $node->title;
$form['rid'][$node->rid] = array(
'#type' => 'textfield',
'#size' => 2,
'#maxlength' => 1,
'#default_value' => $rid,
);
$form['job_name'][$node->rid] = array(
'#type' => 'textfield',
'#title' => t('To'),
'#size' => 40,
'#maxlength' => 42,
'#value' => $title,
);
$form['job_order'][$node->rid] = array(
'#type' => 'textfield',
'#size' => 2,
'#maxlength' => 1,
'#default_value' => $order,
);
}
$form['submit'] = array('#type' => 'submit', '#value' => t('Submit'));
return $form;
}
it returns Array.
I feel the answer is a foreach loop.
any help much appreciated.

当你说：
“it returns Array”...是Echo的输出，还是drupal页面的输出？如果是后者，您需要从 drupal_get_form 调用此函数才能正确呈现表单。因此，在您的情况下，您需要一个带有
'pagecallback' => 的菜单项'drupal_get_form'和'页面参数' =>数组（'mytop Five'）。如果这没有意义，请告诉我:)
When you say:
"it returns Array"... is that the output from an Echo, or the output to the drupal page?if its the latter, you need to be calling this function from
drupal_get_formin order to have the form rendered correctly. so in your case you need a menu item with'page callback' => 'drupal_get_form'and'page arguments' => array('mytopfive').Let me know if that makes no sense :)
