Today, I realised that I hadn't published the code that I used to create the total figures of galleries and photos at the top of the gallery (I said at the end of [Part 2](/blog/create-better-photo-gallery-drupal-part-2/ "Create a Better Photo Gallery in Drupal - Part 2") that I'd include it in [Part 3](/blog/create-better-photo-gallery-drupal-part-3/ "Create a Better Photo Gallery in Drupal - Part 3"), but I forgot). So, here it is:
|
|
|
|
```language-php
|
|
<?php
|
|
|
|
// Queries the database and returns a list of nids of published galleries.
|
|
$galleries = db_query("SELECT nid FROM {node} WHERE type = 'gallery' AND status = 1");
|
|
// Resets the number of photos.
|
|
$output = 0;
|
|
// Prints a list of nids of published galleries.
|
|
while($gallery = db_fetch_array($galleries)) {
|
|
$gallery_id = $gallery['nid'];
|
|
$photos = $photos + db_result(db_query("SELECT COUNT(*) FROM node n, content_type_photo ctp WHERE n.status = 1 AND n.type = 'photo' AND ctp.field_gallery_nid = $gallery_id AND n.nid = ctp.nid"));
|
|
}
|
|
|
|
// Prints the output.
|
|
print 'There ';
|
|
if($photos == 1) {
|
|
print 'is';
|
|
}
|
|
else {
|
|
print 'are';
|
|
}
|
|
print ' currently ';
|
|
print $photos . ' ';
|
|
if($photos == 1) {
|
|
print 'photo';
|
|
}
|
|
else {
|
|
print 'photos';
|
|
}
|
|
print ' in ';
|
|
|
|
// Counts the number of published galleries on the site.
|
|
$galleries = db_result(db_query("SELECT COUNT(*) FROM {node} WHERE TYPE = 'gallery' AND STATUS = 1"));
|
|
|
|
// Prints the number of published galleries.
|
|
print $galleries;
|
|
if ($galleries == 1) {
|
|
print ' gallery';
|
|
}
|
|
else {
|
|
print ' galleries';
|
|
}
|
|
print '.';
|
|
?>
|
|
```
|
|
|
|
It was applied to the view as a header which had the input format set to PHP code.
