Drupal 6，FAPI表单提交两次，为什么？
使用此代码：
drupal_set_message('form id: ' .$form_id. ' send with '. $delta . ' and field: '. $field);
我注意到每次单击 £send" 按钮时，表单都会提交两次，所以我看到如下内容：
表单 ID：formname2 发送 3 和 字段 xxx 表单 id: formname2 发送方式 4、字段xxx
$delta 发生变化，是 cck 多组字段的增量（我正在将一个新字段插入到 cck 内容中）。这是提交函数：
function IngredientsForm_submit($form, &$form_state){
global $user;
$ls_id = $user->ls_id;
$current_ls = node_load($ls_id);
$delta = $form_state['values']['delta'];
$field = $form_state['values']['field_name'];
$form_id = $form_state['values']['form_id'];
$current_ls->field_descrizione_ingrediente[$delta]['value'] = $field;
drupal_set_message('form id: ' .$form_id. ' send with delta: '. $delta . ' and field: '. $field);
node_save($current_ls);
}
奇怪，只有第一次提交的东西似乎保存在数据库中，所以保存的数据是正确的......
知道为什么会有双重提交吗？
using this code:
drupal_set_message('form id: ' .$form_id. ' send with '. $delta . ' and field: '. $field);
I notice that every time I click the £send" button, the form is submitted twice, so I see something like this:
form id: formname2 send with 3 and
field xxx form id: formname2 send with
4 and field xxx
the $delta, that one which change, is the delta of a cck multigroup field (i'm inserting a new field into a cck content). Here's the submit function:
function IngredientsForm_submit($form, &$form_state){
global $user;
$ls_id = $user->ls_id;
$current_ls = node_load($ls_id);
$delta = $form_state['values']['delta'];
$field = $form_state['values']['field_name'];
$form_id = $form_state['values']['form_id'];
$current_ls->field_descrizione_ingrediente[$delta]['value'] = $field;
drupal_set_message('form id: ' .$form_id. ' send with delta: '. $delta . ' and field: '. $field);
node_save($current_ls);
}
Strange, thing only the first submission seems to be saved in the database, so the saved data is correct...
Any idea why there is a double submition?

我会检查表单变量并查看提交函数是否列出多次。这可能位于 $form['#submit'] 或 $form['buttons']['submit']['#submit'] 中，具体取决于这是自定义表单还是默认节点表单。
看来提交函数被调用了两次，但 node_save 正在执行更新而不是插入，因此数据库显示正确。
如果您没有看到重复的提交处理程序被调用，那么也许可以发布构建/更改表单的代码。
I would examine the form variable and see if the submit function is listed more than once. This might be in $form['#submit'] or $form['buttons']['submit']['#submit'] depending on if this is a custom form or a default node form.
It appears the submit function is being called twice but the node_save is doing an update rather than an insert so the database appears correct.
If you do not see a duplicate submit handler being called, then perhaps post your code that builds/alters the form.
我遇到了同样类型的问题，我认为这是 drupal 流程形成的方式。 以下行移动到提交函数中，您会发现该消息只会显示一次。
如果在保存数据后将
I was having the same type of problem, I think it is the way drupal processes forms. If you move the following line
into your submit function after you have saved your data, you will find that the message will only show up once.
