  449. <p>Uploading a file involves the following general process:</p>
    450. 

  450. <ul class="simple">
    451. 

  451. <li>An upload form is displayed, allowing a user to select a file and
    452. 

  452. upload it.</li>
    453. 

  453. <li>When the form is submitted, the file is uploaded to the destination
    454. 

  454. you specify.</li>
    455. 

  455. <li>Along the way, the file is validated to make sure it is allowed to be
    456. 

  456. uploaded based on the preferences you set.</li>
    457. 

  457. <li>Once uploaded, the user will be shown a success message.</li>
    458. 

  458. </ul>

    568. 

  568. directory at the root of your CodeIgniter installation called uploads
    569. 

  569. and set its file permissions to 777.</p>

  587. in your controller using the <code class="docutils literal"><span class="pre">$this-&gt;load-&gt;library()</span></code> method:</p>

    590. 

  590. </div>
    591. 

  591. <p>Once the Upload class is loaded, the object will be available using:

  596. <p>Similar to other libraries, you’ll control what is allowed to be upload
    597. 

  597. based on your preferences. In the controller you built above you set the
