pre_system hook

[eluser]jonyr[/eluser]
Hey Tomcode! Thanks for your answer.
I really aprecciate it.

1 - Thanks for remember the logging.
2 - You're right I rename my hook class from my_cache to smart_cache
3 - For some reason, that I could not detect pre_system is launched two times.

The new scenario is
-------------------
——/application/config/config.php——-
$config[‘enable_hooks’] = TRUE;
$config['log_threshold'] = 2;

——/application/config/hooks.php——

My hook configuration is

$hook['pre_system'][] = array(
'class' => 'site_offline_hook',
'function' => 'is_offline',
'filename' => 'site_offline_hook.php',
'filepath' => 'hooks'
);

$hook['pre_system'][] = array(
'class' => 'smart_cache',
'function' => 'pre_cache',
'filename' => 'smart_cache_hook.php',
'filepath' => 'hooks'
);

$hook['post_system'] = array(
'class' => 'smart_cache',
'function' => 'post_cache',
'filename' => 'smart_cache_hook.php',
'filepath' => 'hooks'
);


Right now, I'm using logg_message as you recomended me.

public function pre_cache()
{
log_message('debug','smart_cache pre_cache function');
}

public function pre_cache()
{
log_message('debug','smart_cache post_cache function');
}

----------------------------------------------------------------
Later of this, I ask for http://mydomain.com/index.php/welcome/index and see into my log file

DEBUG - 2010-02-20 00:45:19 --> smart_cache pre_cache function
DEBUG - 2010-02-20 00:45:20 --> smart_cache post_cache function
DEBUG - 2010-02-20 00:45:20 --> smart_cache pre_cache function

¿What am I doing wrong?

Thanks in advance,
JonyR
