reusing common methods + redirect to current page - El Forum - 01-19-2009

I'm also using the HTTP Referer. I have a basecontroller class which extends all my controllers. It has this method:

Code:
function pagerefresh() {

   // redirects the page to the current page

   header('location:'.$_SERVER['HTTP_REFERER']); 

   flush();

   exit();

}

Next I can call $this->pagerefresh() from my controllers. I use this often in combination with a message, for example:

Code:
if ($userid == $imagedata['user_id']) {

   $this->session->set_flashdata('pagemessage', "You cannot vote on your own images!");

   $this->pagerefresh();

}

Some of my views have this code to display the message:

Code:
&lt;?php

$message = $this->session->flashdata('pagemessage');

if ($message) { ?&gt;

<p class="msg">&lt;?= $message ?&gt;</p>

&lt;?php } ?&gt;

I use this mechanism to redirect the user to the current page whilst also displaying a message. I like this because there is no javascript reliance. The HTTP Referer is a dependency, but it is one I have control over, I also rely on it for Cancel buttons.

This is how I redirect to current page and I think the solution is quite elegant: http://ellislab.com/forums/viewreply/801348/
