Using Flickr API to add dates to photos

Using the flick r API to please my wife Background images downloaded from: http://profesorul09.webs.com/apps/photos/ My wife loves to take pictures, she also loves photo albums. Long time ago I wrote a little script for her that adds the original date to a photo using ImageMagick / This is the story of how to do the same in flick r Note: flick r automatically presents this info at the right side of any image – if it contains this EXIF info -, but I really want to try to do it by myself

Why Flickr? / Which language ,[object Object],[object Object]

PHP for a web app sounds good too

What does this app going to do? ,[object Object]

This time I chose PHP ,[object Object]

Flowchart – kind of ,[object Object]

Once the user has logged into flickr is redirected to just4fun, when he/she can see a list of their albums.

The user click on any of their albums and gain access to the images inside of its selection.

The user click on any of the photos presented and just4fun add the date when the picture was taken as a comment and a tag inside flickr.

First Step: HTML Interface ,[object Object],<img style="height: 84px; width: 369px;" alt="just4fun - a simple app using flickr API" src="http://flickr.nosv.org/out.php?s=just4fun" align="left" hspace="3" vspace="1"> ,[object Object]

phpflickr – lets begin the magic! ,[object Object]

auth.php $api_key = " copy and paste your api key here "; $api_secret = " copy and paste your api secret here "; $default_redirect = "/"; $permissions = "read"; $path_to_phpFlickr_class = "./"; ,[object Object]

In flickr ... ,[object Object]

And the index.php ,[object Object],<?php require_once("./lib/phpFlickr.php"); require_once("./constants.php"); $f = new phpFlickr("api_key","secret"); $f->auth('write'); … ,[object Object]

Get the albums ,[object Object]

And you can paint a list of albums with this couple of lines: foreach($albums['photoset'] as $album) echo "<a href='".$_SERVER['PHP_SELF']." ?id_album =".$album['id']."'>".$album['title']."</a><br/>"; ,[object Object]

For this album -> get the photos ,[object Object],if($_GET['id_album']) $pictures = $f->photosets_getPhotos($_GET['id_album']); ,[object Object],$i = 0; foreach($pictures['photoset']['photo'] as $photo){ echo "<a href='".$_SERVER['PHP_SELF']."?id_photo=".$photo['id']."'><img src='".$f->buildPhotoURL($photo, "Square")."' border='0'></a>"; if($i>=3){ //only needed if you want rows of 4 photos each echo "<br/>"; $i=0; } else $i++;

For this photo -> get the date and use it as a comment/tag ,[object Object]

Step 1: get the information for this photo: $photo_info = $f->photos_getInfo($_GET['id_photo']);
