在 drupal 中获取更改后的表单值

我以 drupal 名称创建了一个模块作为 newmodule。我使用 form alter 来更改用户注册表单以添加一个字段位置。当我提交表单时，我如何获取我创建的新字段的值。

为了详细说明前面的答案，在您的 hook_form_alter 函数中的某处，您想要告诉表单运行您自己的 #submit 处理程序，例如：

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  $form['new_field'] = array( ... ); // You already did this, right?
  $form['#submit'][] = 'mymodule_submit_handler'; // Add this
}

注意：您应该在此处附加 #submit，而不是替换它。然后在您的提交处理程序中，您可以轻松获取该值，例如：

function mymodule_submit_handler($form, &$form_state) {
  $value = $form_state['values']['new_field'];
}

To elaborate on the previous answers, somewhere in your hook_form_alter function, you want to tell the form to run your own #submit handler, e.g.:

function mymodule_form_alter(&$form, &$form_state, $form_id) {
  $form['new_field'] = array( ... ); // You already did this, right?
  $form['#submit'][] = 'mymodule_submit_handler'; // Add this
}

Note: you should be appending on #submit here, not replacing it. Then in your submit handler, you can get the value easily, e.g.:

function mymodule_submit_handler($form, &$form_state) {
  $value = $form_state['values']['new_field'];
}

表单值

$form_state['values']['field_name']

默认存储在中。如果将 #tree 设置为 TRUE，此行为将会改变，并且值将位于嵌套数组中，而不是平面数组中。

将调用两种类型的函数，您可以在其中访问 $form_state 变量。

验证函数用于验证表单数据，检查用户输入的数据是否可接受，例如有效的电子邮件地址等。要添加验证函数，请将其添加到表单更改实现中：
```
$form['#validate'][] = 'name_of_your_validate_handler';
```
提交函数用于对包含有效数据的表单进行操作。通常，您将数据插入数据库，在此处设置重定向等，以添加提交功能，将其添加到您的表单更改实现中：
```
$form['#submit'][] = 'name_of_your_submit_handler';
```

验证和提交函数都采用相同的参数：

function validate_or_submit_func(&$form, &$form_state) {
  // $form is the form array created by drupal_get_form
  // $form_state contains valuable info like, the submitted values and other options.
}

The form value is stored in

$form_state['values']['field_name']

By default. If you set #tree to TRUE this behavior will change, and the values will be in a nested array instead of a flat one.

Two type of functions will be called, where you have access to the $form_state variable.

Validation functions is used validate the form data, to check if the user inputted data is acceptable, like a valid email address etc. To add a validation function add this in your form alter implementation:
```
$form['#validate'][] = 'name_of_your_validate_handler';
```
Submit functions is used to act upon a form with valid data. Typically you insert data into the database, set redirects and such here, to add a submit function add this in your form alter implementation:
```
$form['#submit'][] = 'name_of_your_submit_handler';
```

Both validation and submit functions take the same args:

function validate_or_submit_func(&$form, &$form_state) {
  // $form is the form array created by drupal_get_form
  // $form_state contains valuable info like, the submitted values and other options.
}
