+
+Recently, I converted a client's static HTML website, along with their
+Coppermine Photo Gallery, into a Drupal-powered website.
+
+Over the next few posts, I'll be replicating the process that I used during the
+conversion, and how I added some additional features to my Drupal gallery.
+
+To begin with, I created my photo gallery as described by
+[Jeff Eaton](http://www.lullabot.com/about/team/jeff-eaton) in
+[this screencast](http://www.lullabot.com/articles/photo-galleries-views-attach),
+downloaded all my client's previous photos via FTP, and quickly added them into
+the new gallery using the
+[Imagefield Import](http://drupal.org/project/imagefield_import) module (which I
+mentioned
+[previously](/blog/quickly-import-multiples-images-using-imagefieldimport-module/)).
+
+When I compare this to the previous gallery, I can see several differences which
+I'd like to include. The first of which is the number of photos in each gallery,
+and the date that the most recent photo was added.
+
+To do this, I'd need to query my website's database. To begin with, I wanted to
+have a list of all the galleries on my site which are published, and what
+they're unique node ID values are. To do this, I opened Sequel Pro and entered
+the following code:
+
+```sql
+SELECT title
+AS title, nid
+AS gallery_idFROM node
+WHERE type = 'gallery'
+AND status = 1;
+```
+
+As the nid value of each gallery corresponds with the 'field_gallery_nid' field
+within the content_type_photo field, I can now query the database and retrieve
+information about each specific gallery.
+
+For example, using [aliasing](http://www.w3schools.com/sql/sql_alias.asp) within
+my SQL statement, I can retrieve a list of all the published photos within the
+'British Squad 2008' gallery by using the following code:
+
+```sql
+SELECT n.title, n.nid, p.field_gallery_nid
+FROM node n, content_type_photo p
+WHERE p.field_gallery_nid = 105
+AND n.status = 1
+AND n.nid = p.nid;
+```
+
+I can easily change this to count the number of published nodes by changing the
+first line of the query to read SELECT COUNT(\*).
+
+```sql
+SELECT COUNT(*)
+FROM node n, content_type_photo p
+WHERE p.field_gallery_nid = 105
+AND n.status = 1
+AND n.nid = p.nid;
+```
+
+As I've used the [Views Attach](http://drupal.org/project/views_attach) module,
+and I'm embedding the photos directly into the Gallery nodes, I easily add this
+to each gallery by creating a custom node-gallery.tpl.php file within my theme.
+I can then use the following PHP code to retrieve the node ID for that specific
+gallery:
+
+```php
+<?php
+$selected_gallery = db_result(db_query("
+SELECT nid
+FROM {node}
+WHERE type = 'gallery'
+AND title = '$title'
+"));
+?>
+```
+
+I can then use this variable as part of my next query to count the number of
+photos within that gallery, similar to what I did earlier.
+
+```php
+<?php
+$gallery_total = db_result(db_query("
+SELECT COUNT(*)
+FROM {content_type_photo}
+WHERE field_gallery_nid = $selected_gallery
+"));
+?>
+```
+
+Next, I wanted to display the date that the last photo was displayed within each
+album. This was done by using a similar query that also sorted the results in a
+descending order, and limited it to one result - effectively only returning the
+created date for the newest photo.
+
+```php
+<?php
+$latest_photo = db_result(db_query("
+SELECT n.created
+FROM {node} n, {content_type_photo} p
+WHERE p.field_gallery_nid = $selected_gallery
+AND n.nid = p.nid
+ORDER BY n.created DESC LIMIT 1
+"));
+?>
+```
+
+This was all then added into a 'print' statement which displayed it into the
+page.
+
+```php
+<?php
+if ($selected_gallery_total != 0) {
+  $output = '<i>There are currently ' . $selected_gallery_total . ' photos in this gallery.';
+  $output .= 'Last one added on ' . $latest_photo . '</i>';
+  print $output;
+}
+?>
+```
+
+OK, so let's take a look at the Gallery so far:
+
+You will notice that the returned date value for the latest photo added is
+displaying the UNIX timestamp instead of in a more readable format. This can be
+changed by altering the 'print' statement to include a PHP 'date' function:
+
+```php
+<?php
+if ($selected_gallery_total != 0) {
+  $output = '<i>There are currently ' . $selected_gallery_total . ' photos in this gallery.';
+  $output .= 'Last one added on ' . date("l, jS F, Y", $latest_photo) . '.</i>';
+  print $output;
+}
+?>
+```
+
+The values that I've entered are from
+[this page](http://php.net/manual/en/function.date.php) on PHP.net, and can be
+changed according on how you want the date to be displayed.
+
+As I've added all of these photos today, then the correct dates are being
+displayed. However, on the client's original website, the majority of these
+photos were pubished several months or years ago, and I'd like the new website
+to still reflect the original created dates. As opposed to modifying each
+individual photograph, I'll be doing this in bulk in my next post.
