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
<?php 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.

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:
<?php 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 />'; } ?>
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:
<?php 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"; ?>
The following classes are all returned by tagSearch()
and userSearch()
:
