This example will no longer work as-is – you will need to update your Flashr files as described here.

Somebody on the Flashr mailing list was having difficulties getting to grips with Flashr. Since a picture is worth a thousand words and I needed to do some examples of using Flashr 0.5 anyway, I put this very simple example together…

Basically all it does is connects to the Flickr API and does a search for a tag using It then calls on each of the returned photos to get more detailed information (like authors name, description and tags used). Once it has got all this information it simply traces it to the output window in Flash.

All of this is made much easier by a feature in the as yet not officially released Flashr 0.5. Now when you make multiple requests to the Flickr API the requests are added to a queue and each one executes in turn. This makes writing applications that rely on multiple API requests (such as this one) much simpler.

You can download all the files for this example from here. This includes the latest version of Flashr 0.5 (see the trac timeline for recent changes). The specific file you are interested in is

Here is the entire class which powers this little “application”.

* Class: FlashrSimpleSearch
* Very simple example showing how to search for a tag using Flashr 0.5 and then
* get more detailed information about each matching photo.
* Currently just traces the relvant information out.
