hello there

i want to update multiple rows which comes from a dynamic table in Dreamweaver CS5 (a loop in php) here is my Mysql table :

CREATE TABLE `register`.`s_lessons` (
`lid` int( 5 ) NOT NULL ,
`sid` int( 9 ) NOT NULL ,
`term` int( 5 ) NOT NULL ,
`tid` int( 5 ) NOT NULL ,
`point` double NOT NULL DEFAULT '0',
PRIMARY KEY ( `lid` , `sid` , `term` ) ,
KEY `tid` ( `tid` ) ,
KEY `point` ( `point` )
) ENGINE = MYISAM DEFAULT CHARSET = utf8 COLLATE = utf8_persian_ci;

and this is my page source code:

<?php require_once('../Connections/register.php'); ?>
<?php
session_start();
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}

$colname1_rs1 = "-1";
if (isset($_GET['term'])) {
$colname1_rs1 = $_GET['term'];
}
$colname_rs1 = "-1";
if (isset($_GET['lid'])) {
$colname_rs1 = $_GET['lid'];
}
$colname2_rs1 = "-1";
if (isset($_SESSION['tid'])) {
$colname2_rs1 = $_SESSION['tid'];
}
mysql_select_db($database_register, $register);
$query_rs1 = sprintf("SELECT s_lessons.sid, s_lessons.lid, s_lessons.term, s_lessons.tid, s_lessons.point FROM s_lessons WHERE s_lessons.lid = %s AND s_lessons.term = %s AND s_lessons.tid = %s", GetSQLValueString($colname_rs1, "int"),GetSQLValueString($colname1_rs1, "int"),GetSQLValueString($colname2_rs1, "int"));
$rs1 = mysql_query($query_rs1, $register) or die(mysql_error());
$row_rs1 = mysql_fetch_assoc($rs1);
$totalRows_rs1 = mysql_num_rows($rs1);
$count=mysql_num_rows($rs1);



$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

for ($j = 0, $len = count($_POST['lid']); $j < $len; $j++) {
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
$updateSQL = sprintf("UPDATE s_lessons SET point=%s WHERE tid=%s, lid=%s, sid=%s, term=%s",
GetSQLValueString($_POST['point'] [$j], "double"),
GetSQLValueString($_SESSION['tid'] [$j], "int"),
GetSQLValueString($_POST['lid'] [$j], "int"),
GetSQLValueString($_POST['sid'] [$j], "int"),
GetSQLValueString($_POST['term'] [$j], "int"));

mysql_select_db($database_register, $register);
$Result1 = mysql_query($updateSQL, $register) or die(mysql_error());
}
$updateGoTo = "student_lists.php";
if (isset($_SERVER['QUERY_STRING'])) {
$updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
$updateGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $updateGoTo));
}

<?php
mysql_free_result($rs1);

All i want is that when users click on SUBMIT button values of point column in s_lessons(database table) be updated by new entries from user.

i did my best and result with that code is :

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' lid=888, sid=860935422, term=902' at line 1

I would appreciate any idea.

with prior thanks

I rarely help with Dreamweaver produced code but you could try...



UPDATE
s_lessons
SET
point='%s'
WHERE
tid='%s'
AND
lid='%s'
AND
sid='%s'
AND
term='%s'
