Gowalla API Class (php)

// April 14th, 2010 // Cuvedev, Development, api, gowalla, php

I just quickly made a class for accessing the Gowalla API because I needed it myself. I looked for an existing class on the internet but could only find some crappy stuff on Google Code.
So I decided to make one myself.

The use of the class is fairly simple. Include the class file (don’t forget to add you API-key), make an instance and do your calls.
The class internally uses CURL to do the requests to the server and returns the data as an associative array.
I tried to document the methods enough so it’s easy to use them.

Example:

<!--?php
include('./class.gowalla.php');
$gowalla = new GowallaAPI();
$events	 = $gowalla--->getSpotEvents(846403);
foreach ($events['activity'] as $event)
{ // do stuff }
?&gt;

Feel free to download and comment.

    If the foreach loop, could you use: “echo $event->$activity_url;” to get the url?

    I suppose that would be:

    echo $event['activity_url'];

    Because I make an associative array from the json data, not an object. If you’d rather have an object instead of an array, remove the “true” parameter from json_decode and use:

    echo $event->activity_url;

    note, without the dollar sign in before activity_url

    Hi.
    Could you add a few more examples how to use this class?
    The example code you posted above doesn’t seem to work properly on my server (even though I added my API key)…
    Thanks!

    This is the code I used to test all my methods:
    http://www.cuvedev.net/wp-content/uploads/2010/05/gowalla.php.txt

    It’s pretty dirty looping and doing trial-error with the arguments, but this was the fastest to test my methods. So I’m sure my methods work.

    Another example:

    I hope this helps you out.
    If you keep having problems, just let me know.

    thanks a lot for responding so quickly and providing more examples.

    i tried to implement the api class here: http://www.fishnation.de/bachelor/location-api/ajax/get-gowalla.php

    As soon as i create a new instance of the API class the script keeps seems to have connection problems (the script works fine before instantiating the API class). Right now, the code looks like this:

    Are there further requirements for the script to work? (the PHP version on my server is 5.2)

    And a requirement for the script is CURL, but that’s most of the time installed by default.
    Do you have error_reporting and display_errors on? So we can be sure there’s no error …

    Thanks again for helping me here…
    according to http://fishnation.de/info.php

    error_reporting = 6135 (E_ALL & ~E_NOTICE), display_errors = on, CURL is installed & enabled

    Do I have to make any changes to the class other than pasting in my API key?

    Weird that seems normal. It should work with only changing the apikey.
    You could send me your code (only relevant files) and I could take a look at it if you want.
    (I’m also intrigued why it doesn’t work for you)
