<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>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>

<span class="c1">// Alternately you can set preferences by calling the ``initialize()`` method. Useful if you auto-load the class:</span>
