Change Password

Hi i have created a login script using the tutorial follwing:
http://www.phpfreaks.com/tutorials/40/0.php

it send a generated password to the user via email but does not inlude a script to change the password after activation of the email address and username. Take a look at the link so you can see how the code works. I have got some code but get the follwing error:

Parse error: parse error, unexpected T_STRING in /changepw.php on line 10

Code: this code is called from a form on a html page
-----------------------------------------------changepw.php--------------------------------------

<?
function change_pass($old_pass1, $new_pass1, $new_pass2, $user) {
$oldpass = md5($old_pass1);
$queryoldpass = mysql_query("SELECT PASSWORD FROM users WHERE username = ".$user." AND password = ".$oldpass."");
if($new_pass1 == $new_pass2) {
if($queryoldpass) {
$newpass = md5($new_pass1);
$updatepass = mysql_query("UPDATE PASSWORD FROM users WHERE PASSWORD = ".$oldpass." VALUES ('".$newpass."')";
if(!$updatepass="") {
echo "Error!";
exit;
} else {
echo "Password Updated!";
}
} else {
echo "Paswords DO NOT Match!";
}
}
?>

exit is a function, and should therefore be written exit(). But that's line 11, so try it and post again if you get the same error.

Are you calling the function?

from where?

and how?

Someplace you have a form that prompts the user for their user name, old password, and new password, perhaps in a file called getnewpassword.html. Then you submit that form to some page, perhaps called changepassword.php, which includes the function we're writing in this post. Then you have to call the function with the variables from the form, something like

extract($HTTP_POST_VARS);
change_pass($old_pass, $new_pass1, $new_pass2, $user);

where old_pass, new_pass1, new_pass2, and user are the names of the form elements from the previous page (e.g., you have <input type="password" name="old_pass">)

Hi i found out why it keeps displaying wrong username/password. I changed the password in the DB so it is not encrypted and it successfully changed the password. it doesn't match the old password with the encrypted password. how do i do that?

web_dev

ASKER

Dont worry now i worked it out...what i done was to put

$oldpass = md5($old_pass1);

before the

$queryoldpass = mysql_query("SELECT username FROM users WHERE username = '$username' AND PASSWORD = '$oldpass'") or die(mysql_error());

Thanks for your help...
