<p>Uploading a file involves the following general process:</p>
<ul class="simple">
<li>An upload form is displayed, allowing a user to select a file and
upload it.</li>
<li>When the form is submitted, the file is uploaded to the destination
you specify.</li>
<li>Along the way, the file is validated to make sure it is allowed to be
uploaded based on the preferences you set.</li>
<li>Once uploaded, the user will be shown a success message.</li>
</ul>
<p>To demonstrate this process here is brief tutorial. Afterward you’ll
find reference information.</p>

<p>You’ll notice we are using a form helper to create the opening form tag.
File uploads require a multipart form, so the helper creates the proper
syntax for you. You’ll also notice we have an $error variable. This is
so we can show error messages in the event the user does something
wrong.</p>

<p>Like most other classes in CodeIgniter, the Upload class is initialized
in your controller using the <code class="docutils literal"><span class="pre">$this->load->library()</span></code> method:</p>

$this->upload</p>
</div>
<div class="section" id="setting-preferences">
<h3><a class="toc-backref" href="#id9">Setting Preferences</a><a class="headerlink" href="#setting-preferences" title="Permalink to this headline">¶</a></h3>
<p>Similar to other libraries, you’ll control what is allowed to be upload
based on your preferences. In the controller you built above you set the
following preferences:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">'upload_path'</span><span class="p">]</span> <span class="o">=</span> <span class="s1">'./uploads/'</span><span class="p">;</span>

<span class="c1">// Alternately you can set preferences by calling the ``initialize()`` method. Useful if you auto-load the class:</span>
<span class="nv">$this</span><span class="o">-></span><span class="na">upload</span><span class="o">-></span><span class="na">initialize</span><span class="p">(</span><span class="nv">$config</span><span class="p">);</span>

<p>If you prefer not to set preferences using the above method, you can
instead put them into a config file. Simply create a new file called the
upload.php, add the $config array in that file. Then save the file in:
<strong>config/upload.php</strong> and it will be used automatically. You will NOT
need to use the <code class="docutils literal"><span class="pre">$this->upload->initialize()</span></code> method if you save your
preferences in a config file.</p>
