我想創建一個登錄表單來在php中記錄系統。但我不能這樣做，下面我提到了我的代碼。我也有編碼註冊表格。它工作正常，但登錄表單無法正常工作。註冊表單代碼包含在索引頁面中。但登錄代碼包含在login.php頁面中。從表中檢索數據並使用該數據登錄
幫我解決這個問題。

這是一個簡單的錯字;你應該注意細節。 –
你可以調試並看到？ – Ravi
你能提供更多信息嗎？通常當你遇到像你這樣的錯誤時，你應該看到一個錯誤信息（[也許你需要啓用它們？]（http://stackoverflow.com/questions/1053424/how-do-i-get-php-errors-要顯示）），你有一個？你能給我們更多的信息來重現這一點嗎？ – HPierce
