在drupal中提交后更改表单数据 [英] Change form data after submit in drupal

问题描述

在某些内容类型表单中，我添加了一个复选框.选中此复选框后，我想删除一些提交的数据.

in some content type form I added a checkbox. When this checkbox is checked I want to remove some of the submitted data.

为此，我创建了一个自定义模块 (my_module.module):

To do so I created a custom module (my_module.module):

function my_module_form_alter(&$form, &$form_state) {
    // ...
    $form['#submit'][] = 'my_module_form_alter_submit';
}

function my_module_form_alter_submit($form_id, $form_values) {
    drupal_set_message(t('Submit Function Executed!'));
}

我怎样才能告诉这个模块只引用某个包含类型的表单?提交时如何删除数据?

How can I tell this module to refer only to the form of a certain containt type? And how can I remove data when it is submitted?

推荐答案

假设您正在更改节点编辑表单，您可以有条件地添加提交回调，例如(在您的 hook_form_alter 中):

Assuming you are altering a node edit form, you can either conditionally add the submit callback such as (in your hook_form_alter):

if(isset($form['#node']) && $form['type']['#value'] == 'page') {
    $form['#submit'][] = 'my_module_form_alter_submit';
}

或者，您可以以类似的方式检查提交回调中的 $form 参数.

or, you could check the $form argument in the submit callback in a similar fashion.

您缺少 hook_form_alter 的第三个参数，它应该是 $form_id，并且您的提交回调应该采用如下参数:

You are missing the third argument to the hook_form_alter which should be $form_id, and your submit callback should take the arguments such as:

function my_module_form_alter_submit($form, &$form_state) { ... }
