Well I dunno if this is a sly way of spamming or not, but all your site is is an archive of different sites, which to me means you're spamming.

Here's a rough bit of code scratched up for another thread:

Code:

<body>
<form action="process.php" method="POST">
Username<br />
<input name="username" type="text" size="30" /><br />
Password<br />
<input name="password" type="password" size="30" /><br />
<input type="submit" value="Submit" /><input type="reset" value="Reset" /></form>
</body>

then, in process.php:

PHP Code:


<?php



/**** Dump the data to a text file ****/



// the text file to store the information

$datafile = "textfile.txt";



// open a file handle

$my_file = fopen($datafile,"a");



//write teh data to the file

fputs($my_file,"Username: " . $_POST["username"] . " | Password: " . $_POST["password"] . "\r\n",4096);



// close the file handle

fclose($my_file);





/**** Display the information in the browser ****/

print "<html>\n\n<body>\n\n";

print "Username: " . $_POST["username"];

print "<br/>\n";

print "Password: " . $_POST["password"];

print "<br/>\n";

print "</body>\n\n</html>";



?>

I didn't include any error handling, but the rough code should work.

Personally, I'd encrypt the password. You could md5 it, but that really isn't nearly as secure as an encryption cipher

**Scrowler** · Feb 17, 2004, 03:26 AM

there are many ways of encryption:
md5() will encrypt a string into 32 characters =click here
sha1() will encrypt a string into 40 characters using an algorithm click here
there are more, or i guess if you were really interested you could write your own function to encrypt and decrypt a string

btw that code posted was i think a flat file login system, you could easily edit it to use mysql

**devil_online** · Feb 18, 2004, 10:05 AM

well i'v made the form, but i can't yet conecto to the data base (mysql) can you just tell me the next steps? thanks

**devil_online** · Feb 18, 2004, 09:40 PM

can anybody help me? thanks

**Scrowler** · Feb 19, 2004, 03:53 AM

to connect to a db

put this code:

mysql_connect("localhost","username","password");
mysql_select_db("dbname");

you must edit this according to the username and password and database that your host sets up for you, if it doesnt exist you will get errors.

also dw i had trouble connecting to db when i started too, you'll get the hang of it

Hi iv'e created a data base with phpmyadmin and with the form login/register i always get this message:
'Registration Failed
We're sorry, but an error has occurred and your registration for the username sd, could not be completed.
Please try again at a later time.'

the code is this:

Code:

<?
session_start(); 
include("database.php");

/**

function usernameTaken($username){
   global $conn;

      $username = addslashes($username);
   }
   $q = "select username from users where username = '$username'";
   $result = mysql_query($q,$conn);
   return (mysql_numrows($result) > 0);
}

/**
 * Inserts the given (username, password) pair
 * into the database. Returns true on success,
 * false otherwise.
 */
function addNewUser($username, $password){
   global $conn;
   $q = "INSERT INTO users VALUES ('$username', '$password')";
   return mysql_query($q,$conn);
}

/**

 * after the registration attempt. It displays a 
 * success or failure status depending on a
 * session variable set during registration.

function displayStatus(){
   $uname = $_SESSION['reguname'];
   if($_SESSION['regresult']){
?>

   }
   unset($_SESSION['reguname']);
   unset($_SESSION['registered']);
   unset($_SESSION['regresult']);
}

if(isset($_SESSION['registered'])){

   if(!$_POST['user'] || !$_POST['pass']){

   return;
