我有一些对我来说很好的代码,但我一直收到以下错误:
“解析错误:语法错误,意外$结尾 第21行/home/txclanco/public_html/hotmuze/addSong.php“
这是一个脚本,它接受来自表单的输入,检查重复项,如果有重复,它将不会创建一个新行,而只是添加1到'rating'行,其中songname是歌曲类型如果没有重复,脚本会将数据添加为新行。数据类型是:
脚本如下,mysql数据消失:
<?
mysql_connect("localhost", "***", "***") or die(mysql_error());
mysql_select_db("***") or die(mysql_error());
$songname = $_POST['songname'];
$artist = $_POST['by'];
$ratenum = 1;
$chkquery = "SELECT * FROM hotmuze WHERE songname='$songname'";
$plusOneQuery = "SELECT * FROM hotmuze WHERE songname='$songname'";
$updateQuery = "UPDATE hotmuze SET rating='$rating2' WHERE songname='$songname'";
$checkdata = mysql_query($chkquery);
$checkrows = mysql_num_rows($checkdata);
if($checkrows==0)
{
$insquery = "INSERT INTO hotmuze (id, songname, artist, rating) VALUES('', '$songname', '$artist', '$ratenum'";
$insdata = mysql_query($insquery);
}
if($checkrows!=0)
{
$plusData = mysql_query($plusOneQuery);
}
if(mysql_num_rows($plusData)!=0)
{
$result = mysql_fetch_assoc($plusData);
$rating = $result['ratng'];
$rating2 = $rating + 1;
mysql_query($updateQuery);
echo "Data Inserted";
}
?>
第21行:
if($checkrows!=0)
{
// The brace is on line 21
$plusData = mysql_query($plusOneQuery);
}
任何想法脚本可能出错?我知道意外的$ end错误通常意味着有一个支架不合适,但这次,它没关系?

更改此
$insquery = "INSERT INTO hotmuze (id, songname, artist, rating) VALUES('', '$songname', '$artist', '$ratenum'";
到
$insquery = "INSERT INTO hotmuze (id, songname, artist, rating) VALUES('', '$songname', '$artist', '$ratenum')";

VALUES打开和关闭'()'需要
$insquery = "INSERT INTO hotmuze (id, songname, artist, rating)
VALUES('', '$songname', '$artist', '$ratenum')";
答案 2 :(得分:0)
根据右括号数计算左括号的数量。
$ insquery =“INSERT INTO hotmuze(id,songname,artist,rating)VALUES('','$ songname','$ artist','$ ratenum')”;
