我的MySQL更新查询出了什么问题？

Question

I started learning php, I'm having some problems with this mysql query

  mysql_query( "UPDATE boardinfo SET totalPostCount = '" . $GLOBALS['postCount'] + 1 . "' WHERE boardName = '" . $_POST['board'] )

Error: near '1' WHERE boardName = 'Site' at line 1
All I need to do here is to update the value of totalPostCount if it's boardName matches value from $_POST['board']
Please, go easy on me, I've only started this yesterday...

In your statement, quotes are not closed in last.

 mysql_query( "UPDATE boardinfo SET totalPostCount = '" .$GLOBALS['postCount'] + 1 . "' WHERE boardName = '" . $_POST['board']."'" )

If it doesn't solve your issue,try one more thing.

$val = $GLOBALS['postCount'] + 1;
mysql_query( "UPDATE boardinfo SET totalPostCount = '" .$val . "' WHERE boardName = '" . $_POST['board']."'" )

Hope it will solve your problem
