Cookies

[ProbablyX]

Hello!

I'm trying to make a simple log-in system like this:

Welcome page with a user name and a password box and a "Log-in" button, when the user clicks log-in a cookie (or two, one for each?) is set with the username and password and then the user is moved to a "members only" page where the cookie is checked if the username/password is correct and if it is the page is showed else an error is returned.

Does anyone know how to do this?

Thanks!

Use setcookie() to set the cookie, and use

if(isset($_COOKIE['cookiename']) && !empty($_COOKIE['cookiename'])) {
 // all is good
}
else {
   die("You don't have the cookie. You're not welcome here".);
}

sorta thing to check for it.

yeh, I read some info, but the set cookie ting has to be "before any HTML" which means I have to send the user to a page like set_cookie.php?user=123&pass=456 but I don't want the pass&username to be showed on the set cookie page if you understand me 🙂

Not really. You have the form

<form name="blah" action="page2.php" method="post">
Username: <input type="text" name="username">
<br />
Password: <input type="password" name="password">
<br />
<input type="submit">
</form>

Then you have page2.php

<?php
if(!empty($_POST['username'])) {
   if(!empty($_POST['password'])) {
      // check to see if user is valid
      if(user_is_valid) {
         setcookie("blah");
      }
      else {
         echo "You are not a valid user");
      }
   }
   else {
      echo "You need to fill in the password field";
   }
}
else {
   echo "You need to fill in the username field";
}
