PHP MySQL的請求錯誤：解析錯誤：語法錯誤，意想不到的 '％'

Question

我有我的PHP代碼查詢：

$result = mysqli_query($con,"UPDATE operasyonkayitlari SET tarihgun=FROM_UNIXTIME(UNIX_TIMESTAMP(NOW())-28800, "%Y.%m.%d"), tezgah='".$_REQUEST['tezgah']."', operatoradi='".$_REQUEST['operator']."', ayarepoch=UNIX_TIMESTAMP(NOW()), durum='AYARDA' where isemri='".$_REQUEST['isemri']."' and operasyonno='".$_REQUEST['operasyonno']."'"); 

看這密切：

FROM_UNIXTIME(UNIX_TIMESTAMP(NOW())-28800, "%Y.%m.%d") 

用％字符符號給我這個語法錯誤：

Parse error: syntax error, unexpected '%' in C:\wamp\www\ayarabasla.php on line 4 

我是如何用％符號編寫查詢的？

Answer 1

語法高亮顯示您的錯誤。這是一個報價問題。逃生你內心的雙引號：

$result = mysqli_query($con,"UPDATE operasyonkayitlari SET tarihgun=FROM_UNIXTIME(UNIX_TIMESTAMP(NOW())-28800, \"%Y.%m.%d\"), tezgah='".$_REQUEST['tezgah']."', operatoradi='".$_REQUEST['operator']."', ayarepoch=UNIX_TIMESTAMP(NOW()), durum='AYARDA' where isemri='".$_REQUEST['isemri']."' and operasyonno='".$_REQUEST['operasyonno']."'"); 

您可以使用單引號，太：

$result = mysqli_query($con,"UPDATE operasyonkayitlari SET tarihgun=FROM_UNIXTIME(UNIX_TIMESTAMP(NOW())-28800, '%Y.%m.%d'), tezgah='".$_REQUEST['tezgah']."', operatoradi='".$_REQUEST['operator']."', ayarepoch=UNIX_TIMESTAMP(NOW()), durum='AYARDA' where isemri='".$_REQUEST['isemri']."' and operasyonno='".$_REQUEST['operasyonno']."'");
