我爲一個新聞社門戶做一個author_create_post.php並將數據條目插入到mysql數據庫中。 PHP腳本和表單依賴於相同的頁面。表單也使用了驗證規則。當我點擊提交後最終填寫所有表單條目後，我沒有任何錯誤，但是當我檢查我的數據庫時沒有插入條目，問題是什麼？如何解決它？這是我的完整代碼...爲什麼數據沒有插入到mysql數據庫中沒有錯誤出現在屏幕上？

請破壞你的代碼到更多的塊和寫你已經嘗試過https://stackoverflow.com/help/how-爲了進行調試，請詢問 – Indra
嘗試回顯查詢並手動將其插入到數據庫中。你會發現你的錯誤 – Indra
是'$ tbl_post'實際上是一個爲表定義的變量？ –
