How do I make a website private by using dialog prompt box?

Question

I want to use a dialog prompt box to ask for a password before entering one of my private website. Can anyone help me out? Please provide me the HTML code or JS code.

Ok...according to the second answerer, combining HTML and JS is insecure for the password. So I should I use PHP. But I do not have any background of PHP. Could anyone provide a template (code) for me?

Answer 1

For php you need a web server that hosts with PHP and MySQL. A sample is listed below:

Note: You should get yourself familiar with PHP and MySQL

Create MySQL table:

create table logins (
id int unsigned auto_increment not null primary key,
username varchar(20) not null,
password varchar(20) not null,
session varchar(20) not null
)

Insert your logins into MySQL

First, connect to your database with the user and pass your host provider offers. This script should be its own file like connect.php and included in any page you need a db connection
$db=mysql_connect("localhost","mysqluser","mysqlpass");
mysql_select_db("yourdatabase",$db);

$sql="INSERT INTO logins (username, password) VALUES ('yourusername','yourpassword)";
$res=mysql_query($sql);

Login:

By using HTML and JS, the password would be insecure. The user could disable JS, view the source of the page, and get the password. If it is in another file, they could find a way to open up that file and get the password. Also, once they have the page source, they have the whole page. They just have to save that as an html file and open it up.

The best solution would be to read up on some server side languages (php, perl, etc.) That way, they have no way to get to the password info.

Answer 3

If you want to make it truely secure, you have to do it on the server side. Many hosting companies allow you to password protect some directories. Other than that you will need to set up a back end technology like PHP or ASP to check passwords entered against a database entry.
