title: How to call a value from function set_value in Code Igniter?
body: <p>I have a simple task , and i'm using a MVC methods and CI framework for this task.
  I have made a view to input data to database, and it's work, and i make a 2 anchors, those are an [Update] and [Delete], the function delete is working, but the update isn't working.
  After user click anchor [Update], it will linked to another view(update_view), and i want to show the content which i've clicked in the (update_view). and i think it use a set_value to set a second parameter, to show a value in my update_view.
  This is my code in a view(update_view)</p>
  
  <pre><code>  &lt;!-- update_view.php --&gt;
       &lt;!DOCTYPE html&gt;
       &lt;html&gt;
          &lt;head&gt;
              &lt;title&gt;&lt;/title&gt;
          &lt;/head&gt;
          &lt;body&gt;
              &lt;h2&gt;Update&lt;/h2&gt;
              &lt;?php echo form_open('site/update'); ?&gt;
                  &lt;p&gt;
                      &lt;label&gt;Judul : &lt;/label&gt;
                      &lt;input type="text" name="judul" id="judul" value="&lt;?php echo set_value('judul','??')?&gt;"/&gt;
                  &lt;/p&gt;
                  &lt;p&gt;
                      &lt;label&gt;Konten : &lt;/label&gt;
                      &lt;input type="text" name="konten" id="konten" size="100px" value="&lt;?php echo set_value('konten','??')?&gt;"/&gt;
                  &lt;/p&gt;
                  &lt;p&gt;&lt;input type="submit" value="Ubah" /&gt;&lt;/p&gt;
              &lt;?php echo form_close(); ?&gt;
          &lt;/body&gt;
       &lt;/html&gt;

  <p>What should i put in input tag in value attributes, i want to show a value in input fields (judul, konten) from page before where i clicked the anchors.
  I still can't show a image for a view before click, because i'm still don't have 10 rep to share images. so i'will show the coding where the view(options_view) i've clicked the anchors.
  This below is the code in a view(options_view) :</p>
  
  <pre><code>  &lt;!-- options_view.php --&gt;
       &lt;!DOCTYPE html&gt;
       &lt;html&gt;
          &lt;head&gt;
              &lt;title&gt;&lt;/title&gt;
          &lt;/head&gt;
          &lt;body&gt;
              &lt;h2&gt;Create&lt;/h2&gt;
              &lt;?php echo form_open('site/create'); ?&gt;
                  &lt;p&gt;
                      &lt;label&gt;Judul : &lt;/label&gt;
                      &lt;input type="text" name="judul" id="judul" /&gt;
                  &lt;/p&gt;
                  &lt;p&gt;
                      &lt;label&gt;Konten : &lt;/label&gt;
                      &lt;input type="text" name="konten" id="konten" size="100px"/&gt;
                  &lt;/p&gt;
                  &lt;p&gt;&lt;input type="submit" value="Simpan" /&gt;&lt;/p&gt;
              &lt;?php echo form_close(); ?&gt;
              &lt;hr/&gt;
              &lt;h2&gt;Read&lt;/h2&gt;
              &lt;?php if(isset($records)): foreach($records as $baris) : ?&gt;
                  &lt;h3&gt;&lt;?php echo $baris-&gt;judul ?&gt;&lt;/h3&gt;
                  &lt;div&gt;&lt;?php echo $baris-&gt;konten ?&gt;&lt;/div&gt;
                  &lt;?php echo anchor("site/view_update/$baris-&gt;id","[Update]"); ?&gt;
                  &lt;?php echo anchor("site/delete/$baris-&gt;id","[Delete]"); ?&gt;
              &lt;?php endforeach; ?&gt;
              &lt;?php else : ?&gt;
                  &lt;h3&gt;Tidak ada data.&lt;/h3&gt;
              &lt;?php endif; ?&gt;
          &lt;/body&gt;
       &lt;/html&gt;
  </code></pre>
  
  <p>i'm still doubt, whether i should add code in my controller or my view(set_value).
  So anyone can help me to solve this problem. 
  Thank's for help</p>
