Ahora resulta que tengo otro problema:
Código PHP:
<?php
$link = mysql_connect('localhost','root','administrator310005030605');
mysql_select_db('cesfa_invoice',$link);
$sql = "UPDATE invoice SET
DateInvoice = '" . $_POST['DateInvoice'] . "',
LoggedUser = '" . $_POST['LoggedUser'] . "',
CustomerInvoice = '" . $_POST['CustomerInvoice'] . "',
AddressInvoice = '" . $_POST['AddressInvoice'] . "',
PhoneInvoice = '" . $_POST['PhoneInvoice'] . "',
QuantityInvoice = '" . $_POST['QuantityInvoice'] . "',
DescriptionInvoice = '" . $_POST['DescriptionInvoice'] . "',
PriceUnitInvoice = '" . $_POST['PriceUnitInvoice'] . "',
PriceTotalInvoice = '" . $_POST['PriceTotalInvoice'] . "'
WHERE IdInvoice = '" . $_GET['IdInvoice'] . "'";
$result = mysql_query($sql,$link) or die(mysql_error());
header("Location: edit_invoice.php");
?>
Hasta ahora me pongo en la tarea de intentar actualizar registros en la db y nada, no lo hace, actua como cuando guarda un nuevo registro (INSERT).
Ayuda!!
