如何通過Forms API將節點內容提交到節點

Question

我嘗試使用drupal 6.26在drupal數據庫中存儲自定義內容類型 - 節點 。 我已經創建的架構表已經， 但是當我米執行提交表單 的按鈕，我得到了跟隨着錯誤：

user warning: Duplicate entry '0-0' for key 'PRIMARY' query: service_form_submit /* admin : service_form_submit */ INSERT INTO service (nid, vid,uid, fallbackservice_ids , category , biblebasic , blocked , reason_blocked , created , begin , stop) VALUES (0, 0, 0, '', '', '', 0, '', 0, 0, 0) in /var/www/drupal/modules/service/service.module on line 261.

和至少沒有條目存儲在數據庫中，無論是NID， vid，uid和我輸入的其他值似乎都可用。

如何通過$節點是否正確？

function service_form(&$node) { 
function service_form_submit($node) { 

這裏是我如何使用$ node的完整代碼？

是否有任何特定的原因，你正在做這個自定義模塊？爲什麼不創建一個新的內容類型？

如果你真的想用你自己的模塊做到這一點，你看看examples module？ 你真正想看的代碼是here
