PHP Login problem

[Twist3d]

Hello, well i'm trying to create a simple Admin/Moderator login.

But it oddly enough doesn't work. And i'm usually blind and can't spot obvious things so thats what I think it is.

But can anyone help?

 

<?php
session_start();
if (isset($_SESSION['Mod'])){
echo "Mod";
}else{
if (isset($_SESSION['Admin'])){
echo "Admin";
}else{
echo "Login";
}
}
?>

 

This is just the test, but this is on a Navigation bar, this is supposed to changed it to what session is currently logged.

So if I use this PHP code to login:

 

case 'login2':
session_start();
$password = $_POST['password'];
$sql = "SELECT * FROM passwords WHERE Admin='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
session_register("Admin");
echo "<center>Logged in as Administrator</center>";
}else{
$sql2="SELECT * FROM passwords WHERE Moderator='$password'";
$result2 = mysql_query($sql2);
$count2 = mysql_num_rows($result2);
if($count2==1){
session_register("Mod");
echo "<center>Logged in as Moderator</center>";
}else{
echo "<center>Wrong password!</center>";
}
}
break;

 

Then this should log me in as a Mod or Admin, which will changed the Button on the Navbar to either Mod, Admin or Login depending on what session i'm logged in as.

But this doesn't work. I type in the password on the form page, it says on the login2 page (The code above) that i'm logged in as either an admin or mod, but on the page where the NavBar button is supposed to change it remains always "Login".

Any help?

session_register is no longer supported, you should use $_session['session_name'];

 

Try that and see what happens

So the new code is now:

 

<?php
session_start();
if (isset($_SESSION['Mod'])){
echo "Pie";
}else{
if (isset($_SESSION['Admin'])){
echo "Banana";
}else{
echo "Login";
}
}
?>

 

case 'login2':
session_start();
$password = $_POST['password'];
$sql = "SELECT * FROM passwords WHERE Admin='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
$_session['Admin'];
echo "<center>Logged in as Administrator</center>";
}else{
$sql2="SELECT * FROM passwords WHERE Moderator='$password'";
$result2 = mysql_query($sql2);
$count2 = mysql_num_rows($result2);
if($count2==1){
$_session['Mod'];
echo "<center>Logged in as Moderator</center>";
}else{
echo "<center>Wrong password!</center>";
}
}
break;

 

Still doesn't work.

Try This:

case 'login2':
session_start();
$password = $_POST['password'];
$sql = "SELECT * FROM passwords WHERE Admin='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
$_session['Admin'] = 'admin';
echo "<center>Logged in as Administrator</center>";
}else{
$sql2="SELECT * FROM passwords WHERE Moderator='$password'";
$result2 = mysql_query($sql2);
$count2 = mysql_num_rows($result2);
if($count2==1){
$_session['Mod'] = 'mod';
echo "<center>Logged in as Moderator</center>";
}else{
echo "<center>Wrong password!</center>";
}
}
break;

 

I take it your page is refreshing after the query is made? If you are using an ajax link then your navbar will not refresh unless you have it set too, and so the navbar will not recheck for the session

case 'login2':
session_start();
$password = $_POST['password'];
$sql = "SELECT * FROM passwords WHERE Admin='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
$_session['Admin'] = 'admin';
echo "<center>Logged in as Administrator</center>";
}else{
$sql2="SELECT * FROM passwords WHERE Moderator='$password'";
$result2 = mysql_query($sql2);
$count2 = mysql_num_rows($result2);
if($count2==1){
$_session['Mod'] = 'mod';
echo "<center>Logged in as Moderator</center>";
}else{
echo "<center>Wrong password!</center>";
}
}
break;

Nope, still doesn't work.

But I don't get exactly what you mean by the refreshing bit.

I don't have any ajax code in my project. And nothing refreshes, the code above is the login and the navbar feature.

Ok, imagine it like this:

 

Page loads, reads from top to bottom

You login - Does page redirect after this?

Does your redirect reload your navbar?

 

Basically your navbar has already been processed, the code will not be read again unless the navbar is refreshed, so it is basically seeing on 1st run  isset(sessioninfo) = no and continuing, to get it to read yes, it will have to run again, does that make sense?

 

[Twist3d]

No, after you login it doesn't redirect.

It just stays on the page "Logged in as Mod/Admin".

So fare i don't think anything redirects.

 

So after the user logs in, I will make it redirect to the home page?

[herghost]

Yup: something like

 

<?php

 

Header(Location: 'http://www.mysite.com/index.php');

 

?>

[Twist3d]

I tried your way and this way:

 

case 'login2':
session_start();
$password = $_POST['password'];
$sql = "SELECT * FROM passwords WHERE Admin='$password'";
$result = mysql_query($sql);
$count = mysql_num_rows($result);
if($count==1){
$_session['Admin'] = 'Admin';
echo "<center>Logged in as Administrator</center>";
?>
<meta http-equiv="REFRESH" content="0;url=index.php"></HEAD>
<?php
}else{
$sql2="SELECT * FROM passwords WHERE Moderator='$password'";
$result2 = mysql_query($sql2);
$count2 = mysql_num_rows($result2);
if($count2==1){
$_session['Mod'] = 'Mod';
echo "<center>Logged in as Moderator</center>"; 
?>
<meta http-equiv="REFRESH" content="0;url=index.php"></HEAD>
<?php
}else{
echo "<center>Wrong password!</center>";
}
}
break;

 

Both redirected, neither worked.

the superglobal variable is $_SESSION not $_session. As far as i know variable names are case sensitive. Thats most likely your problem
