Replace form_submit with button

[eluser]codejack[/eluser]
Hi, gents.

I'd like to replace the submit button in my forms with a simple a href button.

Code:

echo form_open('login', $attributes); ?>

<p>
&lt;?php echo form_label('Username', 'username'); ?&gt;
&lt;?php echo form_input($username_nice); ?&gt;
</p>

<p>
&lt;?php echo form_label('Password', 'password'); ?&gt;
&lt;?php echo form_password($password_nice); ?&gt;
</p>

<p>
&lt;?php echo form_submit('submit', 'Login'); ?&gt;
</p>

&lt;?php echo form_close(); ?&gt;

So I need to replace the form_submit function with something like this:

Code:

<p>
<a href="#" class="medium nice radius button">Open sesame!</a>
</p>

Is this possible? How would I go about doing this?
