How Do I Carry $from Over?	View Content

Heres my code:

<?php
include_once("db_connect.php");

if(isset($_COOKIE['user']))
{

//get who to steal from

$from = mysql_real_escape_string($_GET['from']);

//check if they selected someone

if(!$from)

{

echo "You haven't selected a user to steal from!";

}

else

{

if(!$_POST['amount'])

{

echo "Amount to steal from ". $from .": <form action='steal.php' method='POST'>

<input type='text' name='amount'><input type='submit' value='Steal'></form>";

}

else

{

//grab the other users money

$grab_other = mysql_query("SELECT money FROM users WHERE username = '$from'");

//extract

$extract = mysql_fetch_assoc($grab_other);

//check if the user is valid

if(mysql_num_rows($grab_other) == 0)

{

}

elseif($extract['money'] == $_POST['amount'])

{

$one = rand(1, $_POST['amount']);

$two = rand(1, $_POST['amount']);

//if they successfully stole

if($one == $two)

{

echo "You've successfully stole from ". $from ."! $". $_POST['amount'] ." has been added to your account!";

}

else

{

echo "They don't have enough money!";

}

}
}
else
{

echo "You must be logged in before you can do this! <a href='index.php'>Home</a>";
}

?>

$from (which is a GET) is who the user wish to steal from. How do I carry that over? If they go he http://composedscripts.zxq.net/money_game/steal.php?from=Justin - And they enter in an amount, it will forget $from and say they haven't entered in a user to steal from. How do I stop this from happening?

Login To Carry The User_id

Hello,

I've been racking my brains (and spending sleepless nights) trying to get a login system to work by where the member will insert their email address as [username] and password (already stored in the DB) - then the page to divert to an administration panel with their User_id for them to only edit their information.

The Code I have so far.....

The login_form.php
Code: [Select]
<?php

//Start session

session_start();

//Unset the variables stored in session

unset($_SESSION['SESS_CLIENT_EMAIL']);
unset($_SESSION['SESS_MAIN_ID']);

?>

//Create query
