Ok..I'm not a noob in using smarty..have been using it for years now but lately I have experienced a weird problem...

Here is the thing..

I have Smarty in a root directory where all other domains are ..for example

Code:
root->
   -> somedomain.com
   -> otherdomain.com
   -> thirddomain.net
   -> classes
             ->Smarty


So smarty is "outside" of "domains"...now I have a class Template which just extends Smarty and it looks like this...

Code:
class Template extends Smarty {
   
   /**
    * Constructor...
    *
    * @return void
    */
   public function __construct() {
      parent::Smarty();
      $this->caching = false;
      $this->template_dir = SMARTY_TEMPLATE_DIR;
      $this->compile_dir = SMARTY_DIR ."templates_c";
      $this->clear_compiled_tpl();

   }
}


Ok..the problem is that "sometimes" when some page under some domain reloads the page itself is displayed corrupted (read: it breaks all over the browser..when you refresh it's gone and everything is ok) but the problem is that the "template" shown will be from another project.....I call them "ghost" pages....I could live with that but the problem I just saw was that on one page the "ghost" page was from their competition (also on our server) which is NOT nice ofcourse...why is this happening and what is causing those "ghost" pages? (there is not any pattern when they appear..but when they do you see a corrupted template from another project..you reload and it's ok again)...

I really do hope I made this clear as this is a strange problem...

Well.. issue might be that you are clearing your templates every call to any of your websites since you are using a common compile_dir.

I would suggest using a unique compile_id for each site, since they each have their own template_dir, but possibly have templates of the same name.
http://smarty.php.net/manual/en/variable.compile.id.php

In this example I just used the hash of the servername.. You can modify that line to make it as unique as you need...

Then you can also remove the clear_compiled_tpl() call... This is killing your processing time if you do this for every page.

Code:

class Template extends Smarty {
   
   /**
    * Constructor...
    *
    * @return void
    */
   public function __construct() {
      parent::Smarty();
      $this->caching = false;
      $this->template_dir = SMARTY_TEMPLATE_DIR;
      $this->compile_dir = SMARTY_DIR ."templates_c";
      $this->compile_id = sha1($_SERVER['SERVER_NAME']);
   }
}

Thanx man Smile

I though noone would even understand the problem Smile

So basicly I just have to use unique id per DOMAIN if I got this right?

Because using your example
$this->compile_id = sha1($_SERVER['SERVER_NAME']);

will always generate the same hash as the domains are on the same server(server_name = 'localhost') ...

How about using a BASEURL constant? because it holds www.domainname.com and than sha1-it? How that sounds? Or did I completely misunderstood the point....

Yes, the whole point is you need to create a unique ID for each site IF you are using the same compile and/or cache directories for multiple sites..

FYI $_SERVER['SERVER_NAME'] returns the HOST HEADER used to connect to your site... So it is not the physical server... it is the domain name used to connect to that server ie somedomain.com

So yeah if you're doing it all through http://localhost for some reason then there is gonna be an issue.

You could use one of your own constants sure... or perhaps

$this->compile_id = sha1($_SERVER['SERVER_NAME'].$_SERVER['SCRIPT_NAME']);
