带有附加参数的表单提交处理程序

对于某些要求，我需要传递附加信息来表单提交处理程序。在表单 api 中，同时定义自定义提交处理程序，因为

$additional_args = array();
$form['#submit'][] = 'my_submit_handler'

我希望将处理程序提交为

function my_submit_handler($form, &$form_state, $additional_args){

原文

For some requirement I need to pass additional information to form submit handler. In form api, while defining custom submit handler as

$additional_args = array();
$form['#submit'][] = 'my_submit_handler'

I expect to submit handler as

function my_submit_handler($form, &$form_state, $additional_args){

提交处理程序由 drupal fapi 调用，因此您不能执行类似的操作。相反，您可以做的是将您需要的内容添加到 $form 或 $form_state 中。通常的做法是：

在表单中添加一个字段，输入 value 来存储该值。如果表单定义中有该值，请不要执行此操作。
```
$form['store'] = array(
  '#type'=> '价值'，
  '#value'=> $值
）；
```
这将在 $form_state['values']['store'] 中提供。

将值添加到 $form_state['storage']，如果您希望将验证句柄中的变量传输到提交处理程序，则完成：

// 验证。
$form_state['存储']['值'] = $值;

...

// 提交
$value = $form_state['存储']['值'];
// 当不再使用时需要取消设置存储的值。
取消设置($form_state['存储']['值']);

The submit handler is called by the drupal fapi, so you can't do something like that. Instead what you can do, is to add what you need, either to the $form, or to the $form_state. The usual approaches is to:

Added a field to the form, type value to store the value. Don't do this if you have the value in the form definition.
```
$form['store'] = array(
  '#type' => 'value',
  '#value' => $value
);
```
This will be available in $form_state['values']['store'].

Add the value to $form_state['storage'], done if you variables in your validation handle you want to transfer to your submit handler:

// Validation.
$form_state['storage']['value'] = $value;

...

// Submit
$value = $form_state['storage']['value'];
// Need to unset stored values when not used anymore.
unset($form_state['storage']['value']);

Drupal 7：自定义参数通过 $form_state['build_info']['args'] 自动传播
这是在 http://api.drupal.org/api/drupal/ 中说的include!form.inc/function/drupal_get_form/7

例如：

hook_form($form, &$form_state, $myAdditionnalArg) {...}

然后在

hook_form_submit($form, &$form_state) {

...
//$form_state['build_info']['args'] 是一个数组，在索引 0 处包含参数 $myAdditionnalArg 的值
...

Drupal 7: Custom arguments are automatically propagated troug $form_state['build_info']['args']
This is said in http://api.drupal.org/api/drupal/includes!form.inc/function/drupal_get_form/7

Ex:

hook_form($form, &$form_state, $myAdditionnalArg) {...}

Then in

hook_form_submit($form, &$form_state) {

...
//$form_state['build_info']['args'] is an array containing at index 0 the value of argument $myAdditionnalArg
...

正如 $form['#submit'] 和 $form['#validate'] 和 $ form['#process'] 不再支持自定义参数，将参数传递给提交处理程序集（如所示代码所示）的建议方法是使用类似于以下内容的代码：

$form['#first_paramater'] = $value;
$form['#submit'][] = 'my_submit_handler';

处理程序将检索值作为 <代码>$form['#first_paramater']。
需要注意的是，代码可以使用不同的字符串来代替 #first_paramater，但它必须以 # 开头。

通常不需要像代码那样设置提交处理程序，但在某些情况下是有必要的，例如更改另一个模块创建的表单，或者为表单中存在的每个提交按钮设置不同的提交处理程序。形式。

drupal_retrieve_form() 保存传递的参数到 $form['#parameters'] 中的表单构建处理程序，其中包含：

$form_id
$form_state参数
传递给表单构建器的

As reported in $form['#submit'] and $form['#validate'] and $form['#process'] no longer support custom parameters, the suggested way to pass parameters to a submission handler set as in the shown code is to use code similar to the following:

$form['#first_paramater'] = $value;
$form['#submit'][] = 'my_submit_handler';

The handler would retrieve the value as $form['#first_paramater'].
To notice that, instead of #first_paramater, the code can use a different string, but it must start with #.

Normally it's not necessary to set a submission handler like the code does, but there are some cases where it is necessary, like to alter a form created by another module, or to set a different submission handler for each of the submission buttons present in a form.

drupal_retrieve_form() saves the parameters passed to the form build handler in $form['#parameters'] which contains:
