title: form_open() not working in codeigniter
body: <p>I am trying to build a simple form in CodeIgniter. My VIEW 'input_view.php' is:</p>
  
  <pre><code> &lt;html&gt;
      &lt;head&gt;
          &lt;link rel="stylesheet" type="text/css" href="&lt;?php echo "$base/$css"?&gt;"&gt;
      &lt;/head&gt;
      &lt;body&gt;
          &lt;div id="header"&gt;
              &lt;?php $this-&gt;load-&gt;view('books_header'); ?&gt;
          &lt;/div&gt;
  
          &lt;div id="menu"&gt;
              &lt;?php $this-&gt;load-&gt;view('books_menu'); ?&gt;
          &lt;/div&gt;
          &lt;?php //echo $title; ?&gt;
          &lt;?php echo form_open('books/input'); ?&gt;
  
              &lt;?php echo $title; ?&gt;
              &lt;?php echo form_input('title'); ?&gt;;
  
              &lt;?php echo $author; ?&gt;
              &lt;?php echo form_input('author'); ?&gt;
  
              &lt;?php echo $publisher; ?&gt;
              &lt;?php echo form_input('publisher'); ?&gt;
  
              &lt;?php echo $year; ?&gt;
              &lt;?php echo form_dropdown('year',$years); ?&gt;
  
              &lt;?php echo $available; ?&gt;
              &lt;?php echo form_checkbox('available','yes',TRUE); ?&gt;
  
              &lt;?php echo $summery; ?&gt;
              &lt;?php echo form_textarea('summery'); ?&gt;
  
              &lt;?php echo form_submit('mysubmit', 'Submit'); ?&gt;
  
      &lt;?php echo form_close(); ?&gt;
  
  
          &lt;div id="footer"&gt;
              &lt;?php $this-&gt;load-&gt;view('books_footer'); ?&gt;
          &lt;/div&gt;
      &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>But when I tried <code>http://localhost/CodeIgniter/index.php/books/input</code>, it does not show the  form, instead shows page upto <code>menu</code>. Whats the problem here?</p>
