[SOLVED] link problem

[thewooleymammoth]

I created a login page a while ago, and i decided to turn it into a two page process, however i cant get the login.php page to link back to whatever page linked to it... i hope that makes sence.

 

page user logs in from: (which i would like to be every page on the site)

<?php
$tp='index.php';
$user2=$_COOKIE['auth'];
if(isset($_COOKIE['auth']))
  {  
  echo "welcome $user2<br>";
  echo "<form method='post' action='login.php'><input type='submit' value='logout' name='logout'>"; 
  }
  
elseif (!isset($_COOKIE['auth']))
  {
  echo "<a>please login:</a><br>
  <table>
  <form method='post'  action='login.php'>
  <tr>
    <td>Username:</td>
    <td><input type='text' name='username'></td>
  </tr>
  <tr>
    <td>Password:</td>
    <td><input type='password' name='password'></td>
  </tr>
  <tr>
    <td><input type='hidden' name='pn' value=$tp>
  <input type='submit' name='loggedin' value='Log In'><br></td>
    <td><a href='resister.php'>Register here</a></td>
  </tr>
</table>";
  }

else
{
echo "error";
}
  ?>

login page:

<?php
$tp=$_post['pn'];
$username="root";
$password="";
$database="userlist";
$table="login";
$connectmysql=mysql_connect('localhost',$username,$password) or die(mysql_error());
$selectdb=mysql_select_db($database) or die(mysql_error());
$user2=$_COOKIE['auth'];


if(isset($_POST['logout']))
{
setcookie("auth", "$user2", time()-3600);
echo "you have logged out<br><a href='$tp'>return to your page</a>";
}

elseif(isset($_COOKIE['auth']))
  {  
  echo "You have already logged in<br>";
  echo "<a href='$tp'>return to your page</a>$tp"; 
  }
  
elseif (isset($_POST['loggedin']))
  {
  $user=$_POST['username'];
  $userpass=$_POST['password'];
  $query=mysql_query("SELECT*FROM $table WHERE username='$user'") or die(mysql_error());
  $result=mysql_fetch_assoc($query);
  $connectmysql;
  $selectdb;
    if($user == $result['username'] && $userpass == $result['password'])
      {
      
      setcookie ('auth', $user, time()+3600);
      echo "You have logged in succesfully.<br> <a href='$tp'>return to your page</a>";
      }
    elseif ($userpass != $result['password'])
      {
      echo "bad user/password combanation please try again.<br> <a href='$tp'>return to your page</a>";      
      }
    
    elseif ($user !== $result['username'])
    {
    echo "bad user/password combanation please try again.<br> <a href='$tp'>return to your page</a>";
    }
  }

else
{
echo "error";
}
  ?>

 

the login.php page just refers back to itself and no matter how i play with the "" '' it never makes a difference

Hi,

 

On your login page, change $_post to uppercase. As $_post['tp'] is undefined, $tp will not be set to the value you expected, so when an empty string is used in your links, they link back to the same page.

 

<?php
$tp=$_POST['pn'];
// ... rest of code here.

 

Cheers,

Darren.
