15.4.1. Introduction to Searching Flickr

Zend_Service_Flickr is a simple API for using the Flickr REST Web Service. In order to use the Flickr web services, you must have an API key. To obtain a key and for more information about the Flickr REST Web Service, please visit the Flickr API Documentation.

In the following example, we use the tagSearch() method to search for photos having "php" in the tags.

Przykład 15.8. Simple Flickr Photo Search

require_once 'Zend/Service/Flickr.php';

$flickr = new Zend_Service_Flickr('MY_API_KEY');

$results = $flickr->tagSearch("php");

foreach ($results as $result) {
    echo $result->title . '<br />';

tagSearch() accepts an optional second parameter as an array of options.

15.4.2. Finding Flickr Users

Zend_Service_Flickr provides three various ways to get Flickr user information:

  • userSearch(): Accepts a string query of space-delimited tags and an optional second parameter as an array of search options, and returns a Zend_Service_Flickr_ResultSet object.
  • getIdByUsername(): Returns a string user ID associated with the given username string.
  • getIdByEmail(): Returns a string user ID associated with the given email address string.

Przykład 15.9. Finding a Flickr User by E-Mail Address

In this example, we have a Flickr user's e-mail address, and we fetch the user information by using the userSearch() method:

require_once 'Zend/Service/Flickr.php';

$flickr = new Zend_Service_Flickr('MY_API_KEY');

$results = $flickr->userSearch($userEmail);

foreach ($results as $result) {
    echo $result->title . '<br />';

15.4.3. Retrieving Flickr Image Details

Zend_Service_Flickr makes it quick and easy to get an image's details based on a given image ID. Just use the getImageDetails() method, as in the following example:

Przykład 15.10. Retrieving Flickr Image Details

Once you have a Flickr image ID, it is a simple matter to fetch information about the image:

require_once 'Zend/Service/Flickr.php';

$flickr = new Zend_Service_Flickr('MY_API_KEY');

$image = $flickr->getImageDetails($imageId);

echo "Image ID $imageId is $image->width x $image->height pixels.<br />\n";
echo "<a href=\"$image->clickUri\">Click for Image</a>\n";

15.4.4. Zend_Service_Flickr Classes

The following classes are all returned by tagSearch() and userSearch(): Zend_Service_Flickr_ResultSet
