Sergio Posted June 11, 2015 Share Posted June 11, 2015 Hello everyone, greetings from Belo Horizonte / Brazil. I'm on the process of converting a site from WP to Processwire, this one: http://www.ricardo-vargas.com I needed a simple Flickr Gallery and tried to find a way to create album pages via API and download the images to the local filesystem (just a few, for cache purposes). So I created yesterday a simple script that, given an album ID, download its data using cURL and save the photos to a temp dir. After that, add them to a new page under /pictures/ Feel free to comment on the code, I'm a designer, not a developer, and this is my first time using PW API You can grab it on GitHub: https://github.com/sjardim/processwire-simple-flickr-album Instructions Download the files Put the templates/get_flickr_sets.php on your templates/ folder. Create a page on Processwire using this template Create or edit the page where the albums will be created. In my case it was /pictures/ IMPORTANT: Add guest edit/create permissions to this /pictures/ page, otherwise the script won't work Create a temp dir on your server and set it on the previous file Get a Flickr API on https://www.flickr.com/services/apps/create/ Add one or more Flickr album IDs on get_flickr_sets.php Open the page using the get_flickr_sets.php template on your browser <?php include "../lib/curl.class.php"; // You will need to get a Flick API Key // Get it here: https://www.flickr.com/services/apps/create/ // Load it on the file below include "../lib/flickr_album_utils.php"; function download_file($url) { // Save the image on local filesystem (You need to create this folder first) // On your server it can be /var/www/name_of_folder/ $tempdir = '/Users/XXX/phpFlickrCache/'; $fp = $tempdir . basename(parse_url($url, PHP_URL_PATH)); // if we already downloaded the images for some reason (like testing), just return it if (!file_exists($fp)) { $fh = fopen($fp, 'wb'); $curl = curl_init($url); curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_BINARYTRANSFER, 1); curl_setopt($curl, CURLOPT_FILE, $fh); curl_exec($curl); curl_close($curl); fclose($fh); } return $fp; } // Get some public album id to test $albumID = ["72157636029541784"]; //$albumID = ["72157649576832173", "72157633296236495", "72157644132091553", "72157636029541784"]; // Load ProcessWire API $pages = wire('pages')->get('/pictures/'); /* -------------------------- GET ALBUM INFO FROM FLICKR -------------------------- */ foreach($albumID as $album) { // Via GET, return album and its photos info $album = fa_get_album($album); // create a new post $page = new Page(); $page->template = 'picture_album'; $page->parent = $pages; // disable page output formatting $page->of(false); $page->name = wire('sanitizer')->pageName($album['title'], true); $page->flickr_album_id = $album['id']; $page->title = $album['title']; $page->generic_integer = $album['total']; //total number of photos on flickr album – OPTIONAL //My client albums descriptions have two phrases, one in English and other in Portuguese // let's separate then by the period, but sometimes there is no period, so the PT description will remain blank $description = explode('.', $album['description']); $en = $languages->get("default"); $page->summary->setLanguageValue($en, $description[0]); $pt = $languages->get("portuguese"); $page->summary->setLanguageValue($pt, $description[1]); $page->set("status$pt", 1); //activate portuguese page $page->save(); // We need to save the page BEFORE adding images /* ------------------------------------ DOWNLOAD AND SAVE IMAGES FROM FLICKR ------------------------------------ */ $images = array(); $i=1; $maxImages = 11; foreach($album["all_images"] as $f) { //we do not want all the photos, just a little bit if ($i >= $maxImages) break; // mount the flickr photo url using its attributes $photo_url = 'https://farm'.$f["farm"].'.staticflickr.com/'.$f["server"].'/'.$f["id"].'_'.$f["secret"].'_b.jpg'; // download and return the image file in the filesystem $images[$album['id']][$i] = download_file($photo_url); // add images to the current page in the loop $page->images->add($images[$album['id']][$i]); $i++; } $page->save(); echo "<p>Created page for album: <strong>".$album['title']. "</strong></p>"; // Tip: Now, after we saved the images to ProcessWire /site/assets/files/, we can safely delete them from the $tempdir if needed } print "<pre>"; print_r($images); print "</pre>"; Admin Screenshot 7 Link to comment Share on other sites More sharing options...
anttila Posted November 9, 2016 Share Posted November 9, 2016 Big thanks for you. I modified your code because I didn't want to fetch images for downloading but just for linking. I made a new template 'kuvat' (means photos) with fields for Flickr gallery id and image field for main page listing. Only bad thing is that user have to add each gallery separately. But works pretty well and better urls than what we had on Drupal. I use smaller thumbnails (q is 150 x 150) for faster loading and Photobox effect for normal photos. <?php include "../lib/curl.class.php"; include "../lib/flickr_album_utils.php"; $album = fa_get_album($item); $images = array(); foreach($album["all_images"] as $f) { $photo = 'https://farm'.$f["farm"].'.staticflickr.com/'.$f["server"].'/'.$f["id"].'_'.$f["secret"].'_b.jpg'; $thumb = 'https://farm'.$f["farm"].'.staticflickr.com/'.$f["server"].'/'.$f["id"].'_'.$f["secret"].'_q.jpg'; echo "<a class='event' href='$photo'><img src='$thumb' alt=''/>"; } ?> 2 Link to comment Share on other sites More sharing options...
