Validating Uploads

Posted By: phelz

don't know if this is the right place to comment the snippets, if it's not please tell me
anyway, in your Users_Controller at row 36 (function detail) you have this code:
$user = $this->get_user($id);
i suppose get_(model) is a function in your Base_Controller which takes the model given in function name after the underscore, loads it & get the record identified by id.
Am i correct? Can you post the code? (i can understand such a behavior in theory but never done it)

Thank

Hye,

Answering my own question because Google is awesome! :) The new URL is here:http://kohanaphp.com/resources/video/page_cache_hook.mov

@Mabogie: You can do this without the page_cache hook. Just use the Cache library to set and get the raw data you'd like to cache as to prevent your scripts from running the query.

I propose a code to manage the cache and let the process of Kohana terminates to be compatible with the display of execution times and other modules or lib whch use 'system.displat' event.

I hope this will help.

PS: Does anyone have an explanation if call argument in callback have to be value or reference for optimisation

<?php defined('SYSPATH') or die('No direct script access.');</p>

// add event 'system.display' eventualy to fill some user variables like kohana render()

// Stop the controller execution benchmark
Benchmark::stop(SYSTEM_BENCHMARK.'_controller_execution');
//Jump to normal end
Kohana::shutdown();
// To avoid exucetion of shutdown twice (bootstrap.php'
exit;
} else {
// inssert event in head of the event list (to save the file with kohana variables or user variables
MY_Event::add_first('system.display', array(&$this, 'save_cache'));

We already have this: date::timespan

I'm creating a web API for an iPhone application and I found this useful.

MY_request.php:

<?php defined('SYSPATH') OR die('No direct access allowed.');

class request extends request_Core {

    public static function is_iphone()
    {
        return (bool) (strpos(strtolower(Kohana::user_agent('agent')), 'iphone') !== false);
    }

}
