Username password

[Anon]

I need to assign username and passwords from specific variables in a form using php.

$psswd = substr($fname, 0, 1);

$psswd = $psswd . $lname;

$psswd = substr($psswd, 0, 2);

$psswd = $psswd . substr($ssn, 5, 4);

$username = substr($fname, 0, 1);

$username = $username . $lname

Can anyone help?

Help with what? Looks like you've got something going there, what is your specific question?

From what you have there this person:
John Doe 555-55-5555
whould end up with:
Username: JDoe
Password: JD5555 (I dropped the - they were just for display).

While this isn't very secure and anyone could guess someone elses username/password if you are only going to be allowing them to use this password 1 and force them to change it on login it shouldn't be too much of a problem. The bigger problem comes from generating "first initial last name" usernames. There are a lot of people out there who have the same first initial and last name. I personally recommend using email addresses as user names this way you are guarenteed that it is unique, you should never run into duplicate email addresses.

I guess what I need is the proper way to plug it in.
Would this work?
<?
function genusername($username){

$username = substr($fname, 0, 1);

$username = $username . $lname

$username .= $username [substr($fname, 0, 1)] . $username [$username . $lname];

return substr($username);

}
?>
<?
function genpassword($password){

$psswd = substr($fname, 0, 1);

$psswd = $psswd . $lname;

$psswd = substr($psswd, 0, 2);

$psswd = $psswd . substr($ssn, 5, 4);


$password .= $psswd [substr($fname, 0, 1)] . $psswd [$psswd . $lname]; . $psswd [substr($psswd, 0, 2)] . $psswd [$psswd . substr($ssn, 5, 4)];


return substr($password);

}
?>

Those functions won't work because you aren't passing them the information that they need.

Your first function needs $fname, and $lname to generate the $username to be returned to the calling function. So your function declaration should look something like this:

function genusername($fname, $lname)

Your second function needst $fname, $lname, and $ssn to generate the password to be returned to the calling function. So your function declaration should look something like this:

function genpassword($fname, $lname, $ssn)

Finally you don't need to pass your returning variables through substr(), especially if you want to return the whole value.

So to use these functions you'd do something like this:

$username = genusername("John", "Doe");
$password = genpassword("John", "Doe", "5555555555");
