Users Online Footer

[bigmtnskier]

Well, Here is my new footer:hugegrin: What it does is loads the html of the index page of the forum and gets the users online. Then, it picks a random user and displays it with GD.

http://frozenpeak.com/kirupa/beetypesig.php

Just to let you know.. I did not use any reference from nokrev's code :P

@a mod: Is it fine to do this, or do you not want the script loading a page from the forum? It could potentially take up some bandwidth, couldn't it? I won't apply it until I hear from one of you...

:sc:

I would imagine that it wouldn't be too taxing on the forums assuming the traffic this place gets. I'd wait for kirupa's take on the situation though. That's a sweet footer though, one of my favorite's I've seen in all the years I've been here. Very smart. (Make my name bold :P )

[TheCanadian]

That is really neat :thumb:

[3d Nirvana]

cool, have it choose from the users viewing the thread it's in a the bottom.... that would be cool!

[bigmtnskier]

Thanks! :beam:


(Make my name bold :P ) :lol: I don't think its possible in GD :P

Edit:


cool, have it choose from the users viewing the thread it's in a the bottom.... that would be cool!
I would if I could, but to my knowledge that is not possible :(

[Jeff Wheeler]

Good idea. Once I tried getting some data from the specific user, but profile pages require you to be logged in. You may notice that I have an account called something like nokrev-script or similar.

I suggest you look at my code and see how I make it so that if there are more characters than will fit, it'll size it down. ;)

Oh, and you really should be using cURL rather than file_get_contents().

[bigmtnskier]

Why cURL instead of file_get_contents?

[kirupa]

Feel free to use it big ;) I doubt a few extra queries will cause any problems.

:thumb:

[kdd]

ahh, finally it said "Hi kdd!" great work! :thumb:
so, basically you're taking whatever is in between <!--logged> and <!-end> and then finding out a way to get each member name, and then making an image file using the php, right?

[kirupa]

There might be an easier way by getting the appropriate data from global.php (http://www.kirupa.com/forum/global.php) I don't fully know all of the methods in it, but I read data from that file in order to display the log-in/register thing on the left columns on the site.

[nobody]

He won't have access to that file, kirupa. If people could see your php files we'd have major security issues :)

[Seb Hughes]

Very Nice Brian :D

[kdd]

yeah kirupa, i can't see it, as xxviii said. otherwise, you guys would be in a huge trouble.

[bigmtnskier]

Thanks kirupa! I have added it up :hugegrin:

If it takes too much bandwidth or queries just delete it. I don't have a problem with that. ;)


He won't have access to that file, kirupa. If people could see your php files we'd have major security issues :) Agreed :P

-bigmtnskier

[kirupa]

Oh, I meant that there are some functions in global.php that could make this easier. I'll try to see if I can go through and provide the code needed to easily retrieve a list of users currently online as an array.

For example, this is the PHP code used to display your log-in status on the site:
<?php
//Change chdir to fit where your forum is.
$real_path = realpath("index.php");
$real_path = dirname($real_path);
chdir("$real_path/");
require('./global.php');
require('./includes/functions_user.php');
chdir("$real_path/");

echo "<body bgcolor=#D2E9FF>";

if ($vbulletin->userinfo['userid'] != 0)
{
echo "<p align=\"left\"><font size=\"1\" face=\"Verdana\">";
echo "Welcome back ";
echo "<br><strong> ";
echo $vbulletin->userinfo['username'];
echo "</strong>";
echo "<br>";
echo "<a target=\"_parent\" href=http://www.kirupa.com/forum/search.php?do=getnew";
echo ">";
echo "New Posts";
echo "</a>";
echo "<font face=\"Verdana\" size=\"3\">&nbsp;</font>";
echo "| ";
echo "<a target=\"_parent\" href=http://www.kirupa.com/forum/usercp.php";
echo ">";
echo "User CP";
echo "</a>";
echo " ";
echo "</font></p>";

}

if ($vbulletin->userinfo['userid'] == 0)
{
echo "

<p><font size=\"1\" face=\"Verdana\">Welcome, <strong>Guest</strong>.<br>
Please log-in.<br>
[<a target=\"_parent\" href=\"http://www.kirupa.com/forum/register.php\"><font color=\"#0000CC\">Register</font></a>]</font><font face=\"Verdana\">
</font><font size=\"1\" face=\"Verdana\">[<a target=\"_parent\" href=\"http://www.kirupa.com/forum/login.php\"><font color=\"#0000CC\">Login</font></a>]</font><font size=\"1\"> </font></p>

";
}

?>
:goatee:

[bigmtnskier]

Although, that will not work unless the footer script is on the same server :(

[Seb Hughes]

Brian nice job. Can i use it as my footer?

[bigmtnskier]

Sure :)

Can you put a "Created by bigmtnskier" under it? Just kidding :P

[Jeff Wheeler]

@kirupa: Hey! You wouldn't do that for me! :(

[bigmtnskier]

@kirupa: Hey! You wouldn't do that for me! :( I guess mine is just cooler!

Just kidding with ya nokrev :P

[Jeff Wheeler]

I sure am jealous. ;)

[nobody]

It's the clash of the dynamic footer titans. Everyone run!

[Jeff Wheeler]

But mine's OOP. Therefore, mine's superior. ;)

-bigmtnskier :)

[Jeff Wheeler]

Blast! Too bad your Create method is !OOP. It's just all the work stuck in one big thing. ;)

Of course, mine is too…

[bigmtnskier]

Blast! Too bad your Create method is !OOP. It's just all the work stuck in one big thing. ;)

Of course, mine is too…
Ah, true indeed.

I just had an ingenious new idea :devious: I won't probably have time for it until after Feb 14th though... :(

[Jeff Wheeler]

Not another hit into my glory! :P

[bigmtnskier]

//Pick another if it is nokrev :P
$usr = ($usr == "nokrev") ? $matches[array_rand($matches)] : $usr; Touche :P btw.. this wasn't my new idea

Don't worry, I won't have user-submitted phases or the witty random funny ones... Like: "I don't eat rulers, and that's a good thing." You will indeed still have your glory. Your footers inspired me to create this thing. ;)

[Jeff Wheeler]

Ha, thanks. :)

And I was curious why I never saw mine. ;)

Oh, and what happens if either a) I'm the only person online, or b) it picks me twice? Then your little tertiary operator won't work correctly. You should use a while loop:


do { $usr = $users[array_rand($users)]; } while ($usr=="nokrev");

Although you may want to do some infinite loop check.

[bigmtnskier]

Yeah, you do have a point. It was just a joke regarding what xxviii said :P

It's the clash of the dynamic footer titans. Everyone run!
I took it out now :)

[kdd]

oh, i just found a bug... if the username is too long, "hi" gets cut off. you probably want to adjust the size of the text depending on the length of the username. :)

[bigmtnskier]

I knew about that :) I'll fix it as soon as I can ;)

[Jeff Wheeler]

Arg! I've returned your volley. :P

http://nokrev.com/dump/kirupa/bigmtskier-footer.jpg

Also added to my footer rotation.

(All in good fun, my friend.)

[freeskier89]

haha lol nokrev :P

This is getting good :D

[Jeff Wheeler]

:P

[bigmtnskier]

Arg! I've returned your volley. :P

http://nokrev.com/dump/kirupa/bigmtskier-footer.jpg

Also added to my footer rotation.

(All in good fun, my friend.) Haha ROFL! :lol: No offence taken :P

I guess I'll have to come up with something... hmm..
This shall be interesting! You shall wait and see....

This is war :gi:

[Jeff Wheeler]

War, it is indeed. :)

Edit: To start off and remind myself of the script, I changed the submitted image format. Hope you like it. (Yes, it is a rip of the one I designed for you.)

[bigmtnskier]

Nice :thumb: I like it a lot better than the old red configuration!

----

Hehe... beat this. :devious:

I made it so that the text is sized down until it fits. Also, I added "Today's Birthdays" You might have to refresh a couple times to see it...

-bigmtnskier :P

[Jeff Wheeler]

Impressive. I'm working on some cURL that you'll be impressed with. ;)

[bigmtnskier]

Cool. What are you creating? Don't worry I won't do it. I have never used cURL before :P

[Jeff Wheeler]

I'm trying to catch some user data through logging in… as a script. ;)

[bigmtnskier]

Hm.. Sounds interesting :) I guess I'll just have to wait and see!

Hacker Nokrev :P Just kidding

[Jeff Wheeler]

Very true. Sadly, when I asked K to host, he wouldn't even dignify me with a response. He's never been so low. :P

[bigmtnskier]

Very true. Sadly, when I asked K to host, he wouldn't even dignify me with a response. He's never been so low. :P :lol: Gee.. I wonder why... :P

[Jeff Wheeler]

Because he dropped something on the floor. He told me after he got up again. ;)

[Seb Hughes]

Sure :)

Can you put a "Created by bigmtnskier" under it? Just kidding :P
