Help with a script which loads next item

[ryanwood4]

I have a script which displays an image, but I now need a script which loads the next image.

 

It simply needs to load a url with an id at the end which is one higher than the current, i.e.

 

Current page: www.example.com/12 Then when you click 'next' it loads www.example.com/13 so it always needs to load +1.

 

Not sure if this makes much sense tbh.

 

Any help is appreciated.

Ok, I have figured it out, it was very simple.

 

I just echoed the current URL and added +1.

Sure, thats pretty easy.

 

First, you'll need to retrieve the current number from the URL with something like this;

 

<?php
//retrieve current number
$currentnumber = parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
// then you redirect
header("Location: http://www.mydomain.com/".($currentnumber+1));
?>

 

The parse_url function is explained here:http://php.net/manual/en/function.parse-url.php

 

EDIT: beat me to it
