Here's the code for my login view, content-sentry.php

Code:

<div id="content">

<div id="login">
<h1>Login</h1>

<div id="login_error">
&lt;?php echo $this->validation->error_string; ?&gt;
</div>

&lt;?php $attributes = array('id' => 'login'); ?&gt;

&lt;?php echo form_open('admin/sentry', $attributes); ?&gt;

<p>
&lt;?php
  echo form_label('Username: ', 'username');
  
  $username = array(
              'name'    => 'username',
              'maxlength'   => '10',
              'size'        => '25',
            );
  echo form_input($username);
  ?&gt;
</p>

<p>
&lt;?php
  echo form_label(' Password: ', 'username');
  $password = array(
              'name'    => 'password',
              'maxlength'   => '10',
              'size'        => '25',
            );
  echo form_password($password);
  ?&gt;
</p>
  
<div>&lt;input type="submit" value="Submit" /&gt;&lt;/div>

&lt;/form&gt;
  
</div>

</div>
