I didn't scroll all the way to the end of the page, apologies for that.

The duplicate usernames are a fairly easy fix: on line 21 of register.php (as copied form the help page) find
'&username'
near the end and of the line change to
'$username'
This line tells the database to check if the username already exists in the database.

I'll upload the code to my site later or tomorrow to try and debug some of the other issues.

kingjackIVV,

OK, here is a link to some fixes that I have done so far. I put it in a format similar to yours and included a some explanation. For the most part, the code was correct. Except for the cosmetic fixes to the forms, the fixes I made were not big.

Login Code Fixes

I can put everything in a ZIP file that you can download, if you like. If there are other issues, let us know and we will see if we can help.

thanks for the help but i found 3 errors 1:the activation link for some reason doesn`t work it says error 404 file not found when i have the activation file
2:i cant get the question marks to work that apear on the registration page
and 3:when i manualy changed the acivatiion to 1 and logged in it sayed that i had succesfully logged in but when i click the link to go to the member page it says i have to log in even though i did already

and one more question how do i get the persons session to time out after 2 hours if they stop doing anything when there logged in?

thanks in advance for any answers

I'll leave the first three points to Philo, or until I have more time, but the session timeout is relatively simple.

You just need to set a timestamp into a session variable when the user logs in. Any time the user visits a page when logged in, even ones that don't require a login you check the timestamp.

If it was set less than two hours in the past then you update it to the current time, otherwise you remove it.

If you do this before any login check then you can simply check for the existence of the timestamp when checking for a login.

Sample code is here, let me know if you have any issues with it.

Okay, I got some time this evening, and I went over the other few problems. I found some more along the way.

First create a folder called 'css' and one called 'js'. The .css file goes into the css folder, and the .js file goes in the js folder. This will fix the question-mark helpers on the register.php page.

As for the rest, make the following changes:

To fix the activation link 404 change register.php line 76. "http://localhost/login/activate.php" changes to "activate.php"
This will need to be replaced with a full url if you want it to work via email.

In activate.php change "if ($id&&$code) {" to "if (isset($id,$code)) {" because, for me at least, this failed when id=0.

To give access to the members area (and other member pages) on login.php change line 27 "$_SESSION['username']==$dbusername;" to "$_SESSION['username']=$dbusername;"
The == checks if a condition is true, while = sets a variable.

To allow successful changing of passwords in changepassword.php change line 22 "WHERE='$user'" to "WHERE username='$user'"
The column to check was missing.

thanks ile try it out

Browser: IE 7

thanks everything is now working except that when i click the activation link to activate the new account it says data missing also it isnt suppose to let you use the same username and password but it does

please tell me how to fix these last 2 problems and then the php login logout register change password and activate account system will be perfect in my eyes

Browser: IE 7

It lets you use the same password again, but the username must be unique. Check that you're using the code linked to by Philo Kvetch and that the username query (around line 26 or 27) in register.php uses $username rather than &username.

The activation link must contain an id and a code parameter. The link sent by register.php should look something like "activate.php?id=4&code=25552321". If not, find where the link is output from register.php (line 76 on my copy) and make sure the line reads: echo "<a href='activate.php?id=$lastid&code=$random'> activate.php?id=$lastid&code=$random </a> </p>";
