title: processing $_POST in codeigniter
body: <p>How do i do this in codeigniter?</p>
  
  <pre><code>$cuisineArr = isset($_POST['cuisine']) ? $_POST['cuisine'] : array();
  </code></pre>
  
  <p>I read somewhere that using $_Post[''] direct is a not the right way and post() should be used
  instead. But how do i do the same in codeigniter?</p>
  
  <p>I'm getting an array from a group of checkbox, then converting it to csv. The non-codeigniter code is below:</p>
  
  <pre><code>$cuisineArr = isset($_POST['cuisine']) ? $_POST['cuisine'] : array();
  $cuisineArrCSV = implode(',',$cuisineArr);
  echo $cuisineArrCSV; 
  </code></pre>
