Thats the code below but everytime I try and register it says that the username is already registered but the datafile is empty. I'm stuck.

<?php
//php user script
//ben speakman


$datafile = 'data.txt';


if($_GET['action'] == 'signup') {

if(!isset($_POST['name']) || !isset($_POST['email']) || !isset($_POST['url']) || !isset($_POST['username']) || !isset($_POST['password'])){

error_message('One or more required fields were left blank!', $_POST['name'], $_POST['email'], $_POST['url'], $_POST['username'], $_POST['password']);
}

$file = file($datafile);
while(list(,$value)=each($file)){ //check if user exists
list($fname,$femail,$furl,$fuser,$fpass,$blank)=sp lit( "\|", $value);
if($username==$fuser){

error_message('Username is allready in use.', $_POST['name'], $_POST['email'], $_POST['url'], $_POST['username'], $_POST['password']);
}
}

$fp = fopen($datafile, 'a');
fwrite($fp, $_POST['name'] . '|' . $_POST['email'] . '|' . $_POST['url'] . '|' . $_POST['username'] . '|' . $_POST['password'] . "|\n");
fclose($fp);
//html for sucessfull signup

Go onto your ftp program, right click file, chmod/edit permissions, 777, OK

Did that but now there's an error, I'll post it in a min.

Ok now it just doesn't register, It stills says username is in use but the error is gone and data file is chmodded to 777
