how i can do it.... i need the data(userid form login) to the next page(successful login) for query.

thanks.GBU

 

I dont really understand, but maybe you can save them in a $variable, and use them later on? ;s explain more please

 

sounds like you should do some php or whatever language your using in php you get variables by either
$_GET['varName']
or
$_POST['varName']

depending on if your using the post or get

 

thanks....
ok. i has 2 page.. one is a login page(page 1) and the other one is page(page 2) if the login success.

so... in a login page, i need to enter "user id" and "password" and send($_POST) it to it self page(login page) to validate the user id and password. if the validation success(true) it will go to the next page(page 2).

but my problem is.... i want the "user id" from page 1 send to page 2. in the page 2, i want to use the "user id" to query database. if login success and go to page 2... the database will be automatic appear(not need the button search).

 

sessions. after you have a successful login on the first page, set $_SESSION['data'] = 'whatever'; Then redirect to page 2. And at the top of both pages, you'll have to add session_start();

 

it still can not function.....
this is my code... please tell me where part i wrong...

page 1.
-------------------------------
<?php
session_start();
$_SESSION['userid']='userid';
$db = mysql_connect("localhost", "root", "gade") or die("Could not connect.");
if(!$db)
{
die("no db");
}
if(!mysql_select_db("gade",$db))
{
die("No database selected.");
}
if($_POST['userid']!='' && $_POST['password']!='')
{
$userid=mysql_real_escape_string($_POST['userid']);
$password=mysql_real_escape_string($_POST['password']);
$result=mysql_query("SELECT * FROM userhtl WHERE userid='$userid' AND password='$password'");

if(mysql_num_rows($result)==1)
{
$row = mysql_fetch_assoc($result);
$_POST['userid'] = $row['userid'];
header("Location: 7.php");

}
else
{
//Validation failed
$error = 'login error';
echo 'Wrong User ID or Password!!';
}
}
else
{
echo 'Please insert user id and password';
}
@mysql_close();
?>

----------------------------------------------------------

and this is the second page. (page 2).
------------------------------------------------

<?php
session_start();

$db = mysql_connect("localhost", "root", "gade") or die("Could not connect.");
if(!$db)
{
die("no db");
}
if(!mysql_select_db("gade",$db))
{
die("No database selected.");
}
$_SESSION['userid']='$userid';

$sql = "SELECT * FROM hotel WHERE userid='$userid'";
$result = mysql_query($sql);

echo '<strong>Hotel information</strong>';
echo "<table border='1'>
<tr>
<th>Hotel Id</th>
<th>Hotel Name</th>
<th>Information</th>
<th>Address</th>
<th>Contact Number</th>
<th>Email</th>
</tr>";
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['hotelid'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['info'] . "</td>";
echo "<td>" . $row['address'] . "</td>";
echo "<td>" . $row['contactno'] . "</td>";
echo "<td>" . $row['email'] . "</td>";
echo "</tr>";
$hotel=$row['hotelid'];
}
//}
echo "</table>";

$sql = mysql_query("select hotelid,room_type,full,available,star from booking where hotelid= '$hotel'");
echo '<strong>Booking Information</strong>';
echo "<table border='1'>
<tr>
<th>Hotelid</th>
<th>Room Type</th>
<th>Full</th>
<th>Rome Available</th>
<th>Room Rating</th>
</tr>";
while($row = mysql_fetch_array($sql))
{
echo "<tr>";
echo "<td>" . $row['hotelid'] . "</td>";
echo "<td>" . $row['room_type'] . "</td>";
echo "<td>" . $row['full'] . "</td>";
echo "<td>" . $row['available'] . "</td>";
echo "<td>" . $row['star'] . "</td>";
echo "</tr>";
}
echo "</table>";
