estoy diseñando un panel donde solo se actualiza un dato, por lo cual no necesito hacer un campo en mi tabla con auto increment pues solo necesito dos campos
img1
img2
ambos de manera int
ahora bien solo deseo hacer un update mas nada e ingresar los id q provienen de mi tabla productos solo eso...
este es mi codigo
Código PHP:
<?php require_once('../Connections/alba.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($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;
}
}
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
$updateSQL = sprintf("UPDATE principales SET img2=%s WHERE img1=%s",
GetSQLValueString($_POST['img2'], "int"),
GetSQLValueString($_POST['img1'], "int"));
mysql_select_db($database_alba, $alba);
$Result1 = mysql_query($updateSQL, $alba) or die(mysql_error());
$updateGoTo = "act_princ_home.php";
if (isset($_SERVER['QUERY_STRING'])) {
$updateGoTo .= (strpos($updateGoTo, '?')) ? "&" : "?";
$updateGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $updateGoTo));
}
mysql_select_db($database_alba, $alba);
$query_Recordset1 = "SELECT * FROM principales";
$Recordset1 = mysql_query($query_Recordset1, $alba) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
mysql_select_db($database_alba, $alba);
