Script to display SU Card balance

joeKel73 · 18-07-2012 2:26pm #1

I know there's a good few IT heads here that might find this handy.

Thanks to a bit of procrastination I put together a PHP script to easily pull up the balance of free teas and coffees from your SU Card on the mobile.

I could link to the script that accepts login details through the URL but couldn't really prove I'm not storing passwords, so here it is instead!

Instructions

Copy PHP code from below and paste into new php file on your own hosting. You'll need cURL enabled hosting.
Enter your login details at the top of the file and save.
Create a cookie.txt file in the same folder and make it writeable (CHMOD 777).
Bookmark the page URL on your mobile - done!

I added a NFC tag to my SU Card so it'll load the webpage directly when swiped. :cool: :cool:

Excuse the messy HTML, feel free to tidy. Cash balance and points appear to be broken on the SU site at the moment, easy update to include them when they're back.

[PHP]<?php

//Replace with your student ID and password
$id = '12345678';
$password = 'yourpassword';

login('http://www.su.nuigalway.ie/users/login','data[UserSecurityKey][student_username]=' . $id . '&data%5BUserSecurityKey%5D%5Bstudent_password%5D=' . $password . '');

$raw_data = grab_page("http://www.su.nuigalway.ie/loyalty/account/");
$raw_data = str_replace(";", "", $raw_data);
$snippet = get_string_between($raw_data, '<tr>
<td>&euro</td>', '</tr>');
$teas = get_string_between($snippet, '<td>', '</td>');
$dinners = get_string_between($snippet, '</td>
<td>','</td>');

echo '<html>
<head>
<meta name="viewport" content="width=device-width" />
</head>
<body>
<center>
<img src="http://omg.wthax.org/sulogo.jpg">
<br>
<table>
<tr><td><strong style="font-size: 700%;">' . (int)$teas . '</style> </td><td> <img src="http://omg.wthax.org/coffee.png"></td><tr>
<tr><td><strong style="font-size: 700%;">' .(int)$dinners . '</strong></td><td> <img src="http://omg.wthax.org/food.png"></td></tr>
</table>
<br>
<h3>' . 10*($teas-((int)$teas)) . '/10 next free drink.
<br>' . 10*($dinners-((int)$dinners)) .'/10 next free dinner.
</h3>
</center>
</body>
</html>';

function get_string_between($string, $start, $end){
$string = " ".$string;
$ini = strpos($string,$start);
if ($ini == 0) return "";
$ini += strlen($start);
$len = strpos($string,$end,$ini) - $ini;
return substr($string,$ini,$len);
}

//Upload a blank cookie.txt to the same directory as this file with a CHMOD/Permission to 777
function login($url,$data){
$fp = fopen("cookie.txt", "w");
fclose($fp);
$login = curl_init();
curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($login, CURLOPT_TIMEOUT, 40000);
curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($login, CURLOPT_URL, $url);
curl_setopt($login, CURLOPT_USERAGENT, $_SERVER);
curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($login, CURLOPT_POST, TRUE);
curl_setopt($login, CURLOPT_POSTFIELDS, $data);
ob_start();
return curl_exec ($login);
ob_end_clean();
curl_close ($login);
unset($login);
}

function grab_page($site){
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER);
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_URL, $site);
ob_start();
return curl_exec ($ch);
ob_end_clean();
curl_close ($ch);
}

?>[/PHP]

Almost completely useless, yet I find myself impressed nonetheless...

And if only I had a mobile with internet...ta all the same

Though when did the points/cash balance go down? I've got a good few saved up and hate to lose their priceless value!

I'm sure it's still on your account, just not showing up on the SU site at the moment.
