Grab number from URL and use it as variable in PHP

Question

I'm working from a Wordpress website, and I need to be able to create a template for a real quick-and-simple custom order page.

The plan is to create pages so that the URL of said page will be http://www.website.com/order-1234

And then, the template being used for that page will have PHP in it that will try and grab the "1234" portion of the URL, and use it as a variable.

$url = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];
$order_id = intval(substr($url, strrpos($url, '/order-') + 4));
echo $order_id;

But the above code is returning a zero "0"

Try +7 - $order_id = intval(substr($url, strrpos($url, '/order-') + 7)); see phpFiddle - phpfiddle.org/main/code/tse-vbr — Sean

actually shouldn't it be +7? Regardless, it should still return "r-1234" -- ahh, the zero is false as it's not a value that can be an int when using "intval()". Try removing that function and see what result you get. — dmayo

even substr($url,-4); but you still need to do some checking — user557846

@Dagon wouldn't that limit orders to 4 digits, as it would not work for order-123 or order-12345 — Sean

try by using www.website.com/order?id=1234

and use

 $getid = $_GET['id']

also when you want to use the get to show the page use the request function

 if ($_REQUEST['id'] == $getid) {
 // do something here
}

something like that :)

This works, although some would say that http://www.website.com/order-1234 looks cleaner/nicer than http://www.website.com/order?id=1234

@Sean you probably right but its the easiest and the fastest way to do it as i know about php so far :P

Unfortunately, Wordpress won't allow me to manually append "?id=1234" to the permalink url when creating a new page. It takes out the question mark. I could modify the mod_rewrite rules, but this needs to be as simple and quick as possible.
