web page loading

[BandanaChaudhury]

I am doing member login program,
i write the form code in one file(let login.php), and give its link to another file(let check.php) where it can check for validity.
if the user exist, then it will load a member page(let member.php).
I don't know how to do that.
Please help me.

I'm sorry, what part are you looking help for, redirecting to member.php, or getting their data to display on member page?

redirecting to member.php

[simplypixie]

Code: Select all

if ($user_authenticated) //use whatever you are using to check user is authenticated, this is just an example
{
header("location: member.php");
} else {
// Do something else here
}

<?php

include("common.php");
session_start();
$username = $_POST['username'];
$password = md5($_POST['password']);

if($username&&$password)
{
$connect = mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("travelpoint") or die(mysql_error());
$query = mysql_query("SELECT * FROM register WHERE username='$username'");
$numrows = mysql_num_rows($query);
if($numrows!=0)
{
//code to login
while($row = mysql_fetch_assoc($query))
{
$dbusername = $row['username'];
$dbpassword = $row['password'];
}
//check to see if they match
if($username==$dbusername&&$password==$dbpassword)
{
header("location: member.php");
1 //echo"You're in! <a href='member.php'>Click</a> here to enter the memeber page!";
$_SESSION['username']=$username;
}
else
die("Incorrect Password!");
}
else
{
echo "That user doesn't exist!";
echo "You have to register first, click the link below";
echo "<a href='../../Travelpoint.com/register.php'><img src='../../images/Register.gif'></a>";
}
}
else
die("Please enter username and password");

?>

If i write it in the place of 1 then it is showing a error msg like
"Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\Travelpoint.com\common.php:199)"
What to modify, i am not getting it.

You must ensure a header redirects happen before you output any html on a page so if you have anything above your php it will not work. If you want to use the echo statement with a link then just do that instead.
