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";

}
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
if($_FILES['photoun']['photodeux']['phototrois']['photoquatre']['error']==0)
{
//copie de la photo dans le répertoire /photos/
copy($_FILES['photoun']['photodeux']['phototrois']['photoquatre']['tmp_name'],"../photos/".$_FILES['photoun']['photodeux']['phototrois']['photoquatre']['name']);
//enregistrement des informations AVEC le nom de la photo
$updateSQL = sprintf("UPDATE categories SET categorie=%s, nom=%s, accroche=%s, 'description'=%s, prix=%s, photoun=%s, photodeux=%s, phototrois=%s, photoquatre=%s WHERE reference=%s",

mysql_select_db($database_maConnexion, $maConnexion);
$Result1 = mysql_query($updateSQL, $maConnexion) or die(mysql_error());
$updateGoTo = "categoriesGestion.php";
if (isset($_SERVER['QUERY_STRING'])) {
$updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
$updateGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $updateGoTo));
}
mysql_select_db($database_maConnexion, $maConnexion);
$query_rscategories = "SELECT * FROM categories";
$rscategories = mysql_query($query_rscategories, $maConnexion) or die(mysql_error());
$row_rscategories = mysql_fetch_assoc($rscategories);
