php if statements with forms

[farril]

hi there. im new to this forum, iv just started trying to learning php and get my head around it.

 

ive got a website, with a simple login script (atm all it does is acknowledge you are logged in and display your username)

 

ive got a login form, but when you login i want that login form to disapear and have another form containing your user control panel.

 

im having real trouble doing this. how do i go about adding this feature?

Have you started using SESSIONS yet? They are used to store data between pages. So if you store something in a session, it will be available on the next page, etc.

 

Once you have validated their login, you will want to store something in the SESSION. For this example, let's user $_SESSION['user']:

$_SESSION['user'] = $user;

Now, you should redirect them to whatever page you need to. Finally, on that page, the code would look like:

if($_SESSION['user']){
  //Logged In
  //print User Control Panel
}else{
  //Not Logged In
  //print Login Form
}

 

Note: In every script that uses sessions, make sure you put the following function at the very beginning of the script:

session_start();

it'd be something like...

 

<?
if(isset($_SESSION['auth'])){
     //display links, etc. for people who are logged in...
}else{
     //display login form or whatever it is you want people to see who aren't logged in...
}

 

i mean, that's it in it's simplest form assuming you are using $_SESSION variables to keep track of the login process.

 

i have nothing else to work with in the way of any of your code .. but that's the general idea.
