insert query & upload of pics

[nuttynibbles]

hi, i got a webpage where it will insert user profile into database and upload their photos into server..

$addQuery="INSERT into user_tbl(userID,....)VALUES('".$userID."',...)";

mysql_query($addQuery)or die('Error, update query failed');

/*******************************
Upload img to folder uploaded_image
*******************************/
$imgName = $_SESSION['imgName'];

if(file_exists("temp/$imgTitle"))
{
rename ("temp/$imgName", "uploaded_image/$imgName") or die ("Could
not copy file");
}

..

how do i ensure that the addQuery or upload of pics do not occur if either one of them has error??

$addQuery="INSERT into user_tbl(userID,....)VALUES('".$userID."',...)";

$sql = mysql_query($addQuery);

if($sql){
[INDENT]/*******************************
Upload img to folder uploaded_image
*******************************/
$imgName = $_SESSION['imgName'];

if(file_exists("temp/$imgTitle"))
{
rename ("temp/$imgName", "uploaded_image/$imgName") or die ("Could
not copy file");
}[/INDENT]
}
