title: Setting and getting COOKIE with CodeIgniter returning random letter
body: <p>I am sure this is 100% wrong so if someone could correct me It would be greatly appreciated. 
  But on the 'index' page it the variable <code>$venuedeets</code> returns a random capitalized letter currently C. </p>
  
  <p>on <strong>events</strong> function - do I need to set the domain, if so how do I set it as base_url, also is it possible to add custom values and attach them to variables such as <code>venuename =&gt; $venue</code>. </p>
  
  <pre><code>$cookie = array(
  'name' =&gt; 'venue_details',
  'value' =&gt; 'Hello',
  'expire' =&gt; time()+86500,
  'path'   =&gt; '/',
  );
  $this-&gt;input-&gt;set_cookie($cookie);
  </code></pre>
  
  <p><strong>index</strong></p>
  
  <pre><code>$this-&gt;load-&gt;helper('cookie');
  
  $this-&gt;input-&gt;cookie('venue_details', TRUE);
  $cookie2 = get_cookie('venue_details');
  $data['venuedeets'] = $cookie2['value'];
  </code></pre>
  
  <p>Thanks.</p>
