title: Codeigniter - Doubt with library and post
body: <p>I have created a library called <code>Fields</code> where I will create some custom fields.</p>
  
  <p>I have a method <code>new()</code> that is checking for the post information and validating what is necessary.</p>
  
  <p>The problem is, how will I send the post information to that library?</p>
  
  <p>Or, should I make the validation on my controller and send the information as a parameter to the method <code>new()</code>?</p>
  
  <p>Thanks in advance for any help.</p>
