<p>There are 21 different preferences available to tailor how your email
messages are sent. You can either set them manually as described here,
or automatically via preferences stored in your config file, described
below:</p>
<p>Preferences are set by passing an array of preference values to the
email initialize method. Here is an example of how you might set some
preferences:</p>

<p>Enables you to send an attachment. Put the file path/name in the first
parameter. For multiple attachments use the method multiple times.
For example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo1.jpg&#39;</span><span class="p">);</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo2.jpg&#39;</span><span class="p">);</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;/path/to/photo3.jpg&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>To use the default disposition (attachment), leave the second parameter blank,
otherwise use a custom disposition:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;image.jpg&#39;</span><span class="p">,</span> <span class="s1">&#39;inline&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>You can also use a URL:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;http://example.com/filename.pdf&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>If you&#8217;d like to use a custom file name, you can use the third parameter:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="s1">&#39;filename.pdf&#39;</span><span class="p">,</span> <span class="s1">&#39;attachment&#39;</span><span class="p">,</span> <span class="s1">&#39;report.pdf&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>If you need to use a buffer string instead of a real - physical - file you can
use the first parameter as buffer, the third parameter as file name and the fourth
parameter as mime-type:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">email</span><span class="o">-&gt;</span><span class="na">attach</span><span class="p">(</span><span class="nv">$buffer</span><span class="p">,</span> <span class="s1">&#39;attachment&#39;</span><span class="p">,</span> <span class="s1">&#39;report.pdf&#39;</span><span class="p">,</span> <span class="s1">&#39;application/pdf&#39;</span><span class="p">);</span>

<p>Example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="c1">// You need to pass FALSE while sending in order for the email data</span>
