在drupal提交后更改表格数据 [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。

为此，我创建了一个自定义模块（my_module.module）：

  function my_module_form_alter（& $ form，& $ form_state）{
 // ... 
 $ form ['＃ submit'] [] ='my_module_form_alter_submit'; 
} 
 
函数my_module_form_alter_submit（$ form_id，$ form_values）{
 drupal_set_message（t（'Submit Function Executed！'））; 
} 
  

我该如何告诉本模块仅提及某个包含的形式类型？在提交数据时如何删除数据？

解决方案

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（在你的hook_form_alter中）：

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

或者，您可以在类似的回调中检查$ form参数

你缺少hook_form_alter的第三个参数，它应该是$ form_id，你的submit回调应该采用如下参数：

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

另请参见：

http://api.drupal.org/api/drupal/developer%21topics%21forms_api.html/6

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

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!'));
}

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?

解决方案

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';
}

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

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) { ... }
