if(isset($_POST["username"])&& isset($_POST["password"])){
include('config.php'); //this one connects to the database
$username = $_POST["username"];
$password = md5($_POST["password"]);
$sql2=mysql_query("SELECT * FROM clinic_staff WHERE username='$username' AND password='$password'");
$count2 = mysql_num_rows($sql2);
if($count2 == 1){
while($row2 = mysql_fetch_array($sql2)){
$id = $row2["staff_ID"];
$position = $row2["position"];
}
$_SESSION["id"] = $id;
$_SESSION["name"] = $username;
$_SESSION["password"] = $password;
$_SESSION["pos"] = $position;
header("location:index.php");
exit();
}
The problem is I can't echo the username in index.php
. I don't know if it is passed successfully. in index.php
i used echo $_SESSION["name"]
;
You need to look at session_start to start a session. Examples are here
I don't see session_start();
. You have to call that function at the top of every page you use session variables. (At least I have to do that on my server, somebody said to me you should actually be able to use Session variables without session_start();
, but everything that needed a session variable stopped working after I removed the calls to session_start();
)
put session_start(); at the beginning of your document with no white space above it.
