php - Cakephp comment form input keeps the same value after i press add -

-

I have created a blog site "Beginner Cake Php With A Newbie Profession" - David Golding. I have the comment view listed below: 

  & lt; Div class = "comment form" & gt; & Lt ;? Php echo $ form- & gt; Create ('Comment') ;? & Gt; & Lt; Fieldset & gt; & Lt; Legend & gt; & Lt ;? Php __ ('add comment') ;? & Gt; & Lt; / Legend & gt; & Lt ;? Php Acor $ form- & gt; Input ('name'); Counterpart $ form-> Input ('content'); Counterpart $ form-> Input ('post_id'); ? & Gt; & Lt; / Fieldset & gt; & Lt ;? Php echo $ form- & gt; End ('send') ;? & Gt; & Lt; / Div & gt; & Lt; Div class = "verb" & gt; & Lt; Ul & gt; & Lt; Li & gt; & Lt ;? Php echo $ html- & gt; Link (__ ('list comments', true), array ('action' => 'index')) ;? & Gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt ;? Php echo $ html-> Link (__ ('list post', true), array ('controller' => gt; 'post', 'verb' => 'index')); ? & Gt; & Lt; / Li & gt; & Lt; Li & gt; & Lt ;? Php echo $ html- & gt; Link (__ ('new post', true), array ('controller' = & gt; 'post', 'verb' = & gt; add ')); ? & Gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; / Div & gt;

After entering the problem, I remain in the names and content areas. Can anyone help me?

Thanks,

Here are the options:

$ The-> save method, location: 

  $ this-> After handling the redirect, you can redirect to your controller after submitting it. ('Action' = & gt; 'index'));

Where is the action, where you want to return.

Or you can clear the values, then in the controller, after $$-> save

$ this-> Data ['comment'] ['name'] = ""; Etc ...

-

SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI).
