PHP Mysql-MySQL_Query命令未运行

Question

Not sure why, but this line does not even give an error, it simply does not run, and also stops any code after it running. I have checked with die("check") either side of the statement, and only runs before.

mysql_query("UPDATE rounds 
             SET `active`='0', `winnerusername`='$WinnerUsername', `winnerid`='$WinnerID', `pot`='$PreviousPot', `paid`='1' 
             WHERE `round`='$CurrentRound' ") or die(mysql_error());

Any idea why it will not run?

Answer 1

Change it as

mysql_query(
  "UPDATE rounds SET `active`='0',
       `winnerusername`='".$WinnerUsername."', 
       `winnerid`='".$WinnerID."', 
       `pot`='".$PreviousPot."', 
       `paid`='1' 
   WHERE `round`='".$CurrentRound."' "
) or die(mysql_error());

Answer 2

try this:

$sql="UPDATE rounds SET active='0', winnerusername='".$WinnerUsername."', winnerid='".$WinnerID."', pot='".$PreviousPot."', paid='1' WHERE round='".$CurrentRound."' ";
$rs=mysql_query($sql,$Your_Connection_String);

with $Your_Connection_String being something like:

$Your_Connection_String=mysql_connect("localhost","username","password");
mysql_select_db("db_name",$Your_Connection_String);

try to echo $sql; below the query and then paste this into a query in PHPMyAdmin or a MySQL Connection program and see what output you get
