@Marc乙建議我用include_once（）的爲我的文件，而不是包含。這解決了我收到的錯誤。
然而，我仍然有我的驗證功能無法正常運行的問題。我發現它並沒有將我的變量傳遞給函數。
顯然，使用Drupal進行SOMETHING不允許通過簡單地在同一個函數中請求全局$變量來接收變量。我不得不聲明$變量是函數外的全局變量，其中$變量是我的數組。
原始的問題：其他
我有我創建的編輯公司的公司信息在我的數據庫的PHP文件。當我訪問drupal之外的頁面時，一切都很好用，但是當它包含在drupal頁面中時（甚至將代碼粘貼到drupal頁面中，我得到我的驗證錯誤，因爲它無法運行我的驗證功能（或者如果我刪除驗證，我的處理功能不工作），我可以註釋掉的功能，如果叫我處理腳本在一份聲明中像（isset（$ _ POST [「提交」]）），它的工作範圍內的Drupal，但我ð喜歡用我的功能
如果我去編輯在Drupal的網頁，我看到以下錯誤：
致命錯誤：不能重新聲明的validate（）（先前聲明的在/ home /內容/ 6649484分之84/ HTML /公/型材/ drupal_commons /自定義/ editcompany/editcompany.php：416）在/home/content/84/6649484/html/commons/profiles/drupal_commons/custom/editcompany/editcompany.php線452
（416就是我所說的第一件事在我的驗證功能，452是相同收盤）
包括在Drupal PHP頁面時，我爲什麼不能使用的功能？什麼是導致與我的功能掛斷，有沒有辦法解決這個問題？這裏是我的代碼：
