For those who aren't in the know, here's a handy way of doing an if and else. It's handy in JS when you want to change something according to a certain status, and also works in PHP:

Instead of this:

[code:1:4541484f83]<?php
$value=2;
if($value<2){$value=2;}
else{$value=$value;}
?>[/code:1:4541484f83]

Use this:

[code:1:4541484f83]<?php
$value=2;
$value=$value<2?2:$value;
?>[/code:1:4541484f83]

Or in JavaScript, with the aid of the magical grab function:

[b:4541484f83]Magical grab function:[/b:4541484f83]
[code:1:4541484f83]<script type="text/javascript"><!--
function grab(o){
return document.all?document.all[o]:document.getElementById?document.getElementById(o):"";
}
//--></script>[/code:1:4541484f83]

You can change the visibility of things like so:

[code:1:4541484f83]onclick="grab('section').style.display=grab('section').style.display=='block'?'none':'block';"[/code:1:4541484f83]

Works a treat.

Basically:
setThisThing=[i:4541484f83]condition[/i:4541484f83]?thisWhen[i:4541484f83]Condition[/i:4541484f83]Is[b:4541484f83]True[/b:4541484f83]:thisWhen[i:4541484f83]Condition[/i:4541484f83]Is[b:4541484f83]False[/b:4541484f83];
Example: value = [i:4541484f83]is value less than 2[/i:4541484f83] ? make it a 2, otherwise : keep it as value

You can stack them up, too:

[code:1:4541484f83]$value=$value<2?$value>5?5:2:$value;[/code:1:4541484f83]

Instead of:

[code:1:4541484f83]
if($value<2){$value=2;}
else if($value>5:$value=5;}
[/code:1:4541484f83]

Hmm, useful. I'm guessing this is a refinement of existing code?
