Short url script problem

This is a wordpress plugin that converts all urls in a post into sm00sh urls. Now I want to edit it and change to a different service so I replaced the api url and it doesn't work!

<?php

Code (markup):

 

You need to provide us with more information, we can't be expected to go though a 113 line script and find an otherwise unspecified problem. What specifically is not working and what error message do you get? Also, how do you know this script is even able to switch API urls?

 

randomly throwing in a completely different service is NOT GOING TO WORK.

 

You don't need soo much code, you can achieve what you want with 3 lines of code.

<?php
$url_to_short = "http://digitalpoint.com";
$shortened_url = file_get_contents("http://spiralurl.x10.mx/api?url=".$url_to_short);

echo $shortened_url;
?>

oh, and try this

<?php
class smsh {
	public function smsh_parse($content)

			$content = str_ireplace($url['bigurl'], $url['smsh'], $content);

		$dom = new DOMDocument();
		$dom->preserveWhiteSpace = FALSE;
		@$dom->loadHTML($content);

		$atags = $dom->getElementsByTagName('a');
		foreach ($atags as $atag) {
			$the_url = $atag->getAttribute('href');
			$new_url = $this->_smsh_process($the_url);
			$urls[] = array( 'bigurl' => $the_url, 'smsh' => $new_url );
