The quickest way to get a password protection system up and running is to use a Prompt box in JavaScript that has a title like "Enter your Email Address". Only you and the relevant users know what the password should be, could even be one each, that can be sorted out at the next page

then pass the "input" directly through the url by changing the .href, like http://www.iSource.net.nz/users/?leTmeIn=
The page that then processes this should also check for the referring page, and three fails from an IP if you like

the php (the next page):
CODE
<?php
// processdownloads.php
if (!isset($_POST['leTmeIn'])) {
?>
<script language=JavaScript>
location.href=document.referrer;
</script>
<?php
} else {
?>
put all your download stuff here
<?php
}
?>


the javascript (the first page):
CODE
<a href="" onclick="return(doOpen());" >downloads</a>

<script language=JavaScript>
function doOpen(){
    pw = prompt('Enter your Email Address','');
    if (pw){
        location.href='processdownloads.php?'+pw+'='
        return(false);
        }
    }else{
        return(false);
    }
</script>


This is a cheats way of dealing with hackers, crackers or anyone else who shouldn't be where you dont want them to be. leTmeIn is the password here

This is quick and simple, but leaves an ugly url and therefore would not be ideal for anywhere that someone could look over your shoulder, or go through you history, but can be hidden in frames

a simple PHP only version would be:
CODE
<?php
if (!isset($_POST['submit'])) {
?>
<form action="" method="post"><input type="password" name="email">
<input type="submit" name="submit" value="Submit"></form>
<?php
} else {
  $pass = $_POST['email'];
  if ($pass!="leTmeIn") {
?>
<script language=JavaScript>location.href=document.referrer;</script>
<?php
  }else {
?>
put the rest of the page here
<?php
  }
}
?>


I hope it helps someone.

ya this is not a secure way of stopping hackers, crackers, etc. go to any legal hack site, like hackthissite.org for example and the number one noob test for hackers would be something like what you just posted. all someone has to do is view the source code and they would get the password.

go to this website here
http://codingforums.com/showthread.php?t=10114

this is a way more secure javascript password and username login.

Notice from rvalkass:

Corrected BBCode.

It is indeed a good method for beginners (like me).
And I would also like to say that your first post was very good as well.

But if you ask me, I would say that using a simple MySql database along with php or asp would do the work and offer more security. In this way viewing the source to find the password will also be in vain.

May not be the most secure, like you said, but it's still pretty nifty! Especially if you're in a bind and need something quick and simple to work with. Thanks smile.gif
