When the user visits viewer.html, they should be prompted to enter a search term. Oncethey have entered the term and hit the submit button, an XHR request for getThumbs.phpshould occur that performs a cURL request of the Flickr API that returns 40 results forphotos that match the search term entered by the user as XML.-­‐ That XML response should be parsed using one of the following methods: OUTPUT 1 – XML to PHPo getThumbs.php should loop through the XML response and output a set of <img />elements that contain thumbnail URLs as the src attribute and the photo_id as the altattribute of each image ONLY for images that were taken on a Monday. OUTPUT 2 – XML from PHPo getThumbs.php should return an XML object to a2.js, and a2.js should loop throughthe XML response and dynamically generate a set of <img /> elements that containthumbnail URLs as the src attribute and the photo_id as the alt attribute of eachimage ONLY for images that were taken on a Monday. Main page (when you click submit loads the php file):

The php file that is loaded when submit is clicked:

<?php/*should contain a PHP script that performs a cURL request for datafrom Flickr using the flickr.photos.search REST API and should return an XMLresponse.*/print "hey";$ch = curl_init();$url = ' http://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=686c634ab46cfad9ea78f85912d7bc0e&text=%24searchText&content_type=1&media=photos&per_page=40&format=rest&api_sig=6c762eab06cf258c37735f5bc90a03fb';curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_URL, $url);$curl_response = curl_exec($ch);curl_close($ch);print "the response: " . $curl_response; /*$params = array('api_key' => '5aa2e3914789e3d69c436425697af6fb','method' => 'flickr.photosets.getPhotos',//'photoset_id' =>'extras' => 'original_format','format'=> 'php_serial');$encoded_params = array();foreach($params as $k => $v){$encoded_params[] = urlencode($k).'=' .urlencode($v);}*/?>

The professor's powerpoint had the above code (in php file) that is not commented out. But I saw a tutorial with the commented out code (incomplete). How do I use this darn flickr.photosets.getPhotos and retrieve its xml??

since the params are in an array, you need to loop through them to construct a query string (like the url example) to build up a URL that you can then use with cURL to make a request to the flickr api. If you put the URL you have now into a browser, you will get an API key invalid error. what you want to produce is a url that looks likes the one there, but uses the values in the commented our code.

but wait... there's more. according to the docs you need to use OAuth.... that's definitely not what one might call a picnichttp://www.flickr.com/services/api/auth.oauth.html

you had a mistake in your url. the format you were defining was rest. i changed it json and was able to get JSON. so this should get you to your next step... OAuth! Welcome to he big boys/girls club. :)
