43.6. Zend_Service_Flickr

43.6.1. 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.

Example 43.27. Simple Flickr Photo Search

$flickr = new Zend_Service_Flickr('MY_API_KEY');

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

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

            

[Note] Optional parameter

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

43.6.2. Finding Flickr Users' Photos and Information

Zend_Service_Flickr provides several ways to get information about Flickr users:

  • userSearch(): Accepts a string query of space-delimited tags and an optional second parameter as an array of search options, and returns a set of photos as 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.

Example 43.28. Finding a Flickr User's Public Photos by E-Mail Address

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

$flickr = new Zend_Service_Flickr('MY_API_KEY');

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

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

            

43.6.3. Finding photos From a Group Pool

Zend_Service_Flickr allows to retrieve a group's pool photos based on the group ID. Use the groupPoolGetPhotos() method:

Example 43.29. Retrieving a Group's Pool Photos by Group ID

$flickr = new Zend_Service_Flickr('MY_API_KEY');

    $results = $flickr->groupPoolGetPhotos($groupId);

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

            

[Note] Optional parameter

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

43.6.4. 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:

Example 43.30. Retrieving Flickr Image Details

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

$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";
