我遇到此錯誤：無法運行查詢：SQLSTATE [23000]：完整性約束違規：1048'membersince'列不能be null無法運行查詢：SQLSTATE [23000]：完整性約束違規：1048'membersince'列不能爲空
這裏我試圖運行我的註冊頁面。
這裏是代碼。我錯過了什麼？我檢查了我的數據庫表/輸入名稱都正確命名爲「membersince」，那麼究竟是怎麼回事？ :(

那麼在猜測$ _POST ['membersince']爲null時，你設置插入語句的參數。 –
爲什麼在'membersince'輸入字段中的<？php'之後有一個右括號（'>'）？ – Shell
