[help regarding IP address]

to expand on what samshell said, in your when you send your info from the form to the database just simply do this
$ip=$_SERVER['REMOTE_ADDR'];

and then just add it into the INSERT like the rest of the data :)

[Registration Form]

[code]if(!$page) { **your register bit** }
if($page == "registered") { echo "You have registered succesfully"; } [/code]

this assumes you are using ?page=
so register.php would display the register form
and register.php?page=registered will display the message :)

[login/message problem]

$_SESSION['username'] = $row['username'];
$_SESSION['email'] = $row['email'];

is from the sender right? well for that simply register $session_user with the session when they login and do a db query for their personal data like email and register them. that way you can just use $session_whatever instead of drawing them each time and causing problems

could be the cure, could not, its still some good advice for ya ;)

[displaying part of body as an acronym on a link, problems]

Ok at the moment I have a list of entries for articles, I want a quick preview when the person hovers over the link, this is the code I have at the moment

[code]$str=$a["body"];
              $newlength="60";              
              $a_body=substr($str, 0, $newlength);
              echo "&nbsp; ● <acronym title=". $a_body ."><a href=showarticle.php?id=". $id .">". $a_title ."</a></acronym> [posted ". $a_date ."]";[/code]

It works to an extent, it only displays the [b]first word[/b], what am I forgetting?

[Renaming a file whilst uploading, cant get the mime type to work]

I acutally decided (before reading your post) to inster $username at the start, so then it doesn't matter if they overwrite a file, because they are changing it for their avatar anyways. Thanks for the help folks

[Renaming a file whilst uploading, cant get the mime type to work]

nevermind i actually found it in the membership tutorial, well the command, then used it for my own diabolical ends :) if anyone wants to know

[code]$ext = strrchr($_FILES['avatar']['name'], ".");
if (move_uploaded_file($_FILES['avatar']['tmp_name'],$upload_dir.session_id() .".". $ext)) {
[/code]

[Renaming a file whilst uploading, cant get the mime type to work]

because its for user avatars, and session id's are unique. That's not important though, I cant get the mime type to add onto the end

[Renaming a file whilst uploading, cant get the mime type to work]

Hi again folks, I have an upload script for avatars/images, but I dont want them to retain their original name I want them to use the session id, now I can get the files to upload with the session ID but I cant get the extension to go on, any help?
I have currently:

[code]$ext = $_FILES['avatar']['type'];
if (move_uploaded_file($_FILES['avatar']['tmp_name'],$upload_dir.session_id() .".". $ext)) {
[/code]

[Welcome "username"]

If you are using sessions, when you first create it in login_process.php or whatever then put
[code]  $session_username=$_POST["username"];
    session_register("session_username");   [/code]

then you can display

[code]<? echo $session_username ?>  [/code]
anywhere on the page, if someone is logged in then it will display theirname you can expand on that by doing this
[code]<?
if(!$session_username) //if there is no session username do the following
{
echo "You are not logged in, please either <a href=login.php>login</a> or <a href=register.php>register</a>, its free!";
}
else //if there is a session username do the following
{
echo "Welcome Back $session_username";
}
?>[/code]
