I have been trying to create a greeting after a user logs in that says “Welcome, first name (dynamic).” so when the user logs in they are greeted with their name. For some reasont it has not been working out. I am new at php so this may be a simple error. Any assist or advice would be useful. Thanks.
main code
session_start();
$mysql_hostname = 'localhost';
$mysql_user = 'username';
$mysql_password = 'password';
$mysql_database = 'db_users2015';
$connect = mysql_connect($mysql_hostname, $mysql_user, $mysql_password)
or die ("Couldn't connect");
echo "<BR>Connection Successful";
//to put data into database
//select database
$db_selected= mysql_select_db($mysql_database, $connect)
or die ("Couldn't connect to the database");
//frontend and backend data processing
$email= $_POST['email'];
$password= $_POST['password'];
//To see if email is registered
$sql = "SELECT COUNT(*) FROM users WHERE email= '{$_POST['email']}'";
$sql_result = mysql_query($sql);
if (mysql_result($sql_result, 0)<1)
{
die("<BR>Email address not found");
}
else{
echo "Login Successful!";
}
//To check if email and password match
$sql = "SELECT count(*) FROM users WHERE email = '$email' AND
password ='$password' LIMIT 1";
$result = mysql_query($sql) or die(mysql_error());
$firstname = $_SESSION['firstname'];
$_SESSION['firstname']= $_POST['firstname'];
if (mysql_result($result, 0) > 0){
echo "<BR>Login Successful, welcome";
echo $_SESSION['firstname'];
}
if (mysql_result($result, 0) < 1){
echo 'wrong password/username combo';
}
?>

Problem is Been here
You are Trying to get First Name from login page html form. but i don’t remember if any login page ever have First name field. so you should get first name from database and put it in
$_SESSION['firstname']
Hope to be clear enough. 🙂
To get data out of database
Change this
To This
This will do the trick
under
//To check if email and password match
put this:
the place where you set your firstname should be changed with this
set firstname by fetching results from database because $_POST[‘firstname’] does not exists in your page.
Thanks.
