<h1>How to Create and Apply Patches</h1>
<p class="posted">10th October 2010</p>
<p>To begin with, a download a fresh copy of Drupal 6.19 and created a copy of the original user.pages.inc file. Within the duplicate file, I made the same changes to the function that I did in earlier code, and saved the changes. Now, within my Terminal, I can navigate to Drupal's root directory and create the patch.</p>
<pre><code class="language-bash">diff -rup modules/user/user.pages.inc modules/user/user.pages2.inc &gt; /Users/oliver/Desktop/different_messages_for_blocked_users.patch
</code></pre>
<p>This command compares the differences between the two files, and creates the specified patch file.</p>
<p>To apply the patch to my Drupal installation, I go back to Terminal and run the following code:</p>
<pre><code class="language-bash">patch -p0 &lt; /Users/oliver/Desktop/different_messages_for_blocked_users.patch
</code></pre>
<p>If, for some reason, I need to reverse the patch, I can run this code:</p>
<pre><code class="language-bash">patch -p0 -R &lt; /Users/oliver/Desktop/different_messages_for_blocked_users.patch
</code></pre>
<p>And that's it!</p>
<p>There is also a Git patch creation workflow, which is described at <a href="http://groups.drupal.org/node/91424">http://groups.drupal.org/node/91424</a>. Thanks to <a href="http://randyfay.com">Randy Fay</a> for making me aware of this, and suggesting a slight change to my original patch creation command.</p>

<h1>Create a Better Photo Gallery in Drupal - Part 3</h1>
<p class="posted">13th October 2010</p>
<p>The next part of the new gallery that I want to implement is to group the galleries by their respective categories. The first step is to edit my original photo_gallery view and add an additional display.</p>
<p>I've called it 'Taxonomy', and it's similar to the original 'All Galleries' view. The differences are that I've added the taxonomy term as an argument, removed the header, and updated the path to be <code>gallery/%</code>. The other thing that I need to do is overwrite the output of the original 'All Galleries' View by creating a file called <code>views-view--photo-gallery--page-1.tpl.php</code> and placing it within my theme directory.</p>
<p>Within that file, I can remove the standard content output. This still outputs the heading information from the original View. I can now use the function called 'views_embed_view' to embed my taxonomy display onto the display. The views_embed_view function is as follows:</p>
<pre><code class="language-php">&lt;?php views_embed_view('my_view', 'block_1', $arg1, $arg2); ?&gt;
</code></pre>
<p>So, to display the galleries that are assigned the taxonomy of 'tournaments', I can use the following:</p>
<pre><code class="language-php">&lt;?php print views_embed_view('photo_gallery', 'page_2', 'tournaments'); ?&gt;
</code></pre>
<p>To reduce the amount of code needed, I can use the following 'while' loop to generate the same code for each taxonomy term. It dynamically retrieves the relevant taxonomy terms from the database, and uses each name as the argument for the view.</p>
<pre><code class="language-php">&lt;?php
$terms = db_query("SELECT * FROM {term_data} WHERE vid = 1");
while ($term = db_fetch_array($terms)) {
print '&lt;h3&gt;' . $term['name'] . '&lt;/h3&gt;';
print views_embed_view('gallery', 'page_2', $term['name']);
}
?&gt;
</code></pre>

<h1>Create a Better Photo Gallery in Drupal - Part 2.1</h1>
<p class="posted">22nd October 2010</p>
<p>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 <a href="/blog/create-better-photo-gallery-drupal-part-2/" title="Create a Better Photo Gallery in Drupal - Part 2">Part 2</a> that I'd include it in <a href="/blog/create-better-photo-gallery-drupal-part-3/" title="Create a Better Photo Gallery in Drupal - Part 3">Part 3</a>, but I forgot). So, here it is:</p>
<pre><code class="language-php">&lt;?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 '.';

</code></pre>
<p>It was applied to the view as a header which had the input format set to PHP code.</p>
