My logon system doesn't seem to register.

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 Code:


<html> 
<head> 
<title>Register</title> 
</head> 
<body> 


<?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)=split( "\|", $value); 
        if($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

havent read ur code but is your flatfile chmodded too 777?

iAdam · 18-02-2008, 09:42 PM

No it isn't, sorry for being a noob but how do I do that?

<?PHP> · 19-02-2008, 07:00 AM

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

iAdam · 19-02-2008, 03:40 PM

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
