{
header("Location: insert.php?alert=1");
die;
}
include "./connect.php";
$sql = "INSERT INTO telematici (nome,gen,feb,mar,apr,mag,giu,lug,ago) VALUES ('$_POST[nome]','$_POST[gen]','$_POST[feb]','$_POST[mar]','$_POST[apr]','$_POST[mag]','$_POST[giu]','$_POST[lug]','$_POST[ago]')";
mysql_query($sql, $conn);
header("Location: insert.php?alert=0");
?>
Codice PHP:
<?php include './page.php';
HtmlHeader();
Navigation();
$message = "";
if (isset($_GET['alert']))
{
if ($_GET['alert'] == 0)
{
$message = "Dati scritti correttamente nel database";
}
if ($_GET['alert'] == 1)
{
$message = "ERRORE: Nessun dato scritto nel database.
Campo NOME deve essere compilato!";

e questo e' il file insert.php
iserisci un
echo $sql;

così vedi cosa ti restituisce

per me l'errore è nella sintassi che viene creata

ciao
