Spotlight script [SELECT ONLY VIA USERS IN DATABASE]

[Independent]

Right, I was bored and got "inspired" by Jack's thread.. This collects the image from Habbo still, but spotlights a random Habbo inserted into the database table.

<?php
// MySQL Connect code.

$grab = mysql_query("select * from `habbos`");
$amount = mysql_num_rows($grab);

$random = rand(1, $amount);

$getusers = mysql_query("SELECT * FROM `habbos` WHERE `id`='$random'");
$showuser = mysql_fetch_array($getusers);
$showusername = $showuser['username'];

echo '<img border="0" src="http://www.habbo.' . $showuser['habbohotel'] . '/habbo-imaging/avatarimage?user='. $showuser['habboname'] .'&action=&direction=4&head_direction=3&gesture=sml&size=l&img_format=png"><br />Hello, '.$showuser['habboname'] .' plays Habbo.' . $showuser['habbohotel'] . '</a>';

?>

MySQL Code:

CREATE TABLE IF NOT EXISTS `habbos` (
  `id` int(3) NOT NULL auto_increment,
  `habboname` varchar(30) NOT NULL,
  `habbohotel` varchar(30) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;

If you wish to insert users, here's the SQL code;

INSERT INTO `habbos` (`id`, `habboname`, `habbohotel`) VALUES
(1, 'Xedon', 'co.uk'),
(2, 'Nooblah', 'co.uk');

Like that..

Hope this helps, I'd have made a inserter as well but I'm not sure if people would have wanted that, this is best for staff pages, like "Random staff".

I'll make an inserter file if you request it.

I know this is badly coded, but I made it in 10mins.

Edit: This may show the same image twice, but after another refresh it shouldnt.

Theres only one problem with your random.

What if you have to delete an entry, that means the id's could be like:

id | habbo
1 | Habbo 1
2 | Habbo 2
4 | Habbo 3
5 | Habbo 4
7 | Habbo 5

So if the random picks up id 3, there's no entry for it.

You could use mysql_affected_rows() to check if it exists, then if it doesn't choose another random one.

Wouldn't it just be easier to have the query as:

$random = mysql_query("SELECT habbonames FROM habbos ORDER BY RAND() LIMIT 1");
$habbo = mysql_fetch_array($random); 

With the array variable $habbo[0] being the actual Habbo?

I was just about to post exactly the same thing ss.

Im not sure im right, but when you use rand it makes a seprate temp table, which can slow down the execution time of a script if there are too many rows in the table.

Yep, you seem to be correct. But then again you'd have to have quite a large table for it to make much of an difference and seeing as it's going to be to show the name off a staff member or something it shouldn't have that many entries anyway .

Looks like I may have to redo our random spotlight. We have 3,374 entries

I think this is much more appropriate for a spotlight script
