how do i password protect files on web page

[AARON Carter]

I am making a small project on php and want some help in it. How do i exactly password protect the files i upload. I mean i want to upload some content and want it to be accessible to users of the site, but they should not be able to download if they are not registered, that is they must have password to download.

On click to download the file, direct it to a function which will check for password. The function should look somewhat like this;

function check(){
var realPassword = 'check';
var password = prompt('Enter the password','');

if(password !=' ' && password !=null)
{
  if(password != realPassword)
  {
		alert("Download not accessible");
  }
}
else{
	alert("Enter the password");
        return false;
      }
}

You may still have to do some work on this, but it might just prevent the user from downloading, if password is wrong. Post if you still have any querry.

well i tried doing what you said, with the html redirect to a page with a validation check by the code you gave, but this is not much help. I am wondering,. is there any way by which i could just password protect my file itself?

I was thinking of just that, so to password protect the file itself, what you can do is use the .htaccess. First make a file named htpasswd and store the username and password there like this; username:12querry34. Keep this file in the folder that is accesible on web. Now make a htaccess file which will be something like this;

AuthUserFile /usr/local/safe/protect/.htpasswd
AuthGroupFile /dev/null
AuthName PasswordProtect
AuthType Basic
require user username

In the first line give the directory location of the htpasswd file, and the last line give the users you want to give access.
