Documentation on Hooks?

[nexflo]

Right now just want to setup a very simple logger, which tells me the time taken for the page to render and how much memory was used.

I setup a super ultra light module as follows:

    public function init() {

    $this->addHookBefore('Page::render', $this, 'timeStart'); 

        $this->addHookAfter('Page::render', $this, 'getStat'); 

 

    }

 

 

    public function timeStart(){

        $this->$timestart = microtime(true);

    }

 

    public function timeNow(){

        return microtime(true)-$this->$timestart;

    }

 

    public  function convert($size) {

        $unit=array('b','kb','mb','gb','tb','pb');

        return @round($size/pow(1024,($i=floor(log($size,1024)))),2).' '.$unit[$i];

    }

    

    public function getMemory(){

        return $this->convert(memory_get_peak_usage(true));

    }

 

    public function getStat(){

        echo '<!-- Page generated in '.$this->timeNow().' secs, Memory Usage: '.$this->getMemory().' -->';

    }

 

 

issue is: i want to hook into the very first and very last instance of processwire..i cant really seem to find the right hooks, or a documentation about it?

 

cheers

Look for my ChromePhp debug module.

If you want from start to end of full pw youd have to insert your code in top and bottom index.php gateway. No way to hook that obviously.

All methods in core prefixed with 3 underscores can be hooked by className::method.

While Soma is right that the only way to get 100% before and after everything that happens is to literally put it in index.php, there are a couple of hooks that may provide what you need. An autoload module's init() function is a good starting point, and ProcessPageView::finished is a good hook to end with.
