似乎無法得到這個簡單的PHP電子郵件/郵編表單提交工作

以下代碼供用戶通過此表單提交電子郵件和郵編。它不檢查數據或將數據插入到數據庫中，也不會正確顯示任何錯誤消息。似乎無法得到這個簡單的PHP電子郵件/郵編表單提交工作

我試着複製並粘貼你的腳本，註釋掉數據庫部分 - 所有的錯誤信息都對我完全出來。你有沒有得到任何輸出？或者它只是你看到的同一頁？我們需要更多的幫助。 – Repox

我沒有任何輸出，頁面只是刷新。 –

我相信我的db連接文件config.php是正確的。 –

「;」的力量... :)

改變這一行：

$email_check_query  = "SELECT email FROM datingshotgun WHERE email ='$email'";

到：

$email_check_query  = "SELECT email FROM datingshotgun WHERE email ='$email';";

同樣適用於：

$insert_email_query  = "INSERT INTO datingshotgun (email,zip) VALUES ('$email','$zip')";

到：

$insert_email_query  = "INSERT INTO datingshotgun (email,zip) VALUES ('$email','$zip');";

你知道嗎，我知道了......出於某種原因，我的數據庫中的id字段未設置爲自動遞增。愚蠢的我，這個伎倆。
