在 Drupal 中通过 AHAH 传递参数
Drupal 6.22
我有一个空页面,除了一个带有两个输入值的表单,并且在提交时必须显示基于该值的查询结果。结果可能会显示在新窗口或同一页面上,唯一的要求是表单仍然易于访问。我尝试使用 AHAH 来实现此目的,但我还没有找到发送输入的方法。
这就是我现在所拥有的:
function somemodule_menu()
{
$items['somemodule/js'] = array(
'page callback' => 'somemodule_js',
'access arguments' => array('access content'),
'type' => MENU_CALLBACK,
);
return $items;
}
function somemodule_form()
{
$form = array();
$format = 'd/m/Y';
$default = 'Y-m-d 00:00:00';
$form['from'] = array(
'#type' => 'date_popup',
'#title' => t('From'),
'#default_value' => date($default),
'#date_format' => $format,
'#required' => TRUE
);
$form['to'] = array(
'#type' => 'date_popup',
'#title' => t('To'),
'#default_value' => date($default, mktime(0, 0, 0, date('n') + 6)),
'#date_format' => $format,
'#required' => TRUE
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Send'),
'#ahah' => array(
'path' => 'somemodule/js',
'wrapper' => 'entry-wrapper',
'method' => 'replace',
'progress' => array(
'type' => 'bar',
'message' => t('Please wait...')
)
)
);
return $form;
}
function somemodule_js()
{
return drupal_json(array('status' => TRUE, 'data' => "some data"));
}
这会提交表单并将一些数据
正确插入到entry-wrapper
中。我知道我可以进行以下更改:
function somemodule_menu()
{
$items['somemodule/js/somevar'] = ...
}
function somemodule_form()
{
...
$form['submit'] = array(
'#ahah' => array(
'path' => 'somemodule/js/wharrgarbl',
...
}
function somemodule_js($string)
{
return drupal_json(array('status' => TRUE, 'data' => $string));
}
并且我会返回 wharrgarbl,但静态值反而违背了这一点。
有没有办法在第一次提交后从该函数内访问 somemodule_form
的表单状态,或者我是否以完全错误的方式处理这个问题?
Drupal 6.22
I have an empty page except for a form that takes two input values and, when submitted, must display the result of a query based on that. The result may be displayed in a new window or on the same page, the only requirement is that the form is still easily accessible. I've tried to use AHAH to achieve this but I haven't found a way to send along the input.
This is what I have now:
function somemodule_menu()
{
$items['somemodule/js'] = array(
'page callback' => 'somemodule_js',
'access arguments' => array('access content'),
'type' => MENU_CALLBACK,
);
return $items;
}
function somemodule_form()
{
$form = array();
$format = 'd/m/Y';
$default = 'Y-m-d 00:00:00';
$form['from'] = array(
'#type' => 'date_popup',
'#title' => t('From'),
'#default_value' => date($default),
'#date_format' => $format,
'#required' => TRUE
);
$form['to'] = array(
'#type' => 'date_popup',
'#title' => t('To'),
'#default_value' => date($default, mktime(0, 0, 0, date('n') + 6)),
'#date_format' => $format,
'#required' => TRUE
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Send'),
'#ahah' => array(
'path' => 'somemodule/js',
'wrapper' => 'entry-wrapper',
'method' => 'replace',
'progress' => array(
'type' => 'bar',
'message' => t('Please wait...')
)
)
);
return $form;
}
function somemodule_js()
{
return drupal_json(array('status' => TRUE, 'data' => "some data"));
}
This submits the form and correctly inserts some data
into entry-wrapper
. I know that I can make the following changes:
function somemodule_menu()
{
$items['somemodule/js/somevar'] = ...
}
function somemodule_form()
{
...
$form['submit'] = array(
'#ahah' => array(
'path' => 'somemodule/js/wharrgarbl',
...
}
function somemodule_js($string)
{
return drupal_json(array('status' => TRUE, 'data' => $string));
}
and I'll get wharrgarbl
back, but a static value rather defeats the point.
Is there a way to access the form state of somemodule_form
from within that function after the first submission or am I going about this entirely the wrong way?

我不知道我是如何错过它的,但钩子表单的签名是
hook_form(&$node, $form_state)
。 PHP 的宽恕有时可能是一种诅咒。不管怎样,出现了一个完全不相关的谷歌搜索 这个关于多步表单的问题,这就是我最终所做的。I don't know how I missed it but the signature for hook form is
hook_form(&$node, $form_state)
. PHP's forgiveness can be a curse sometimes. Anyway, a completely unrelated Google search turned up this question about multistep forms, which is what I ended up doing.
