Creating PHP Login screens

sagat

Hi, i have a quick question. I am trying to build and easy login screen with username and password using PHP. The login screen should contain client side checking written in javascript and it should be able to perform server side checking. Do you know how i can do this? I am using Dreamweaver which has PHP functionality built in.

Thanks

Hi,

Yeah, I think most of us can get that working. (There is actually a lot of info on this on the forum. ).
Give it a try, and let us know where you get stuck.

What you'd need is a form to submit, a file / database with valid users and some if / then / else statements.
For the client-side authentication you'd need to have a search for javascript on google.

(I recently did it, and found complete scripts in minutes).

Enjoy!

If you are a complete newbie, I suggest you have a read in some manuals (books or the internet) and do a little trial and error first, before making a user-authentication program.

This website has some good articles. But also on internet are some tutorials.

Create a form in dreamweaver, two input boxes, username and password. Also have a submit button. Point the form to wards a file to do the processing, an example filename is login.php.

Login.php should take the vars $GET["userid"] and $GET["password"]. Compare these with a database of members and use
if ($_GET["password"] == "password") (or whatever)
then redirect when the password is OK. As leatherback said search, this will be the easiest and most comprehensive way to find out more. Just press search at the top of the page and look for login script. You may also want to have a look at a tutorial or two if you say you are a complete novice, I would recommend webmonkey, they are where I gained my footing with PHP, I highly recommend them, the address is:

If you don't know HTML i would recommend looking through the tutorials concerning that as well, it is very useful knowledge to have when working with PHP.

well, being a login form i would suggest using POST so your password doesnt just show up in the URL

<form method="post" action="process.php">
<input type="text" name="user" /><br />
<input type="password" name="pass" /><br />
<input type="submit" name="submit" value="Login" />
</form>

is your form

on process.php

<?
//get variables from form
$user = $_GET['user'];
$pass = $_GET['pass'];
.
.
.
?>

on process.php you will want to connect to a database that has usernames and passwords and do a Select password from table WHERE user = $user.. and then compare the 2 passwords ,if its a match, redirect them to wherever, else tell them that it was an invalid user/pass match
