Using Observers instantiated from application-top.php?

[enigmabomb]

Hey,

I'm trying to make an observer that checks a condition, and adds a product to the cart if the condition is true. However, I can't even get the skeleton of the concept to work. I put my config.classname.php in auto-loaders and the class.classname.php in includers/classes/observers The best I get is it puking the source of the class above the page, at one point the page wouldnt load.
Here is the code:

config

<?php
$autoLoadConfig[90][] = array('autoType'=>'class',
                              'loadFile'=>'observers/class.platinum.php');
$autoLoadConfig[90][] = array('autoType'=>'classInstantiate',
                              'className'=>'platinum',
                              'objectName'=>'platinum');

?>

And the class...

class platinum extends base 
{

    function myplatinum()
    {
         $this->attach($this,array('NOTIFIER_CART_ADD_CART_END'));
    }
    
    function update(&$callingClass, $notifier, $paramsArray) 
    {
        echo "BIG OBNOXIOUS LETTERS<br><br><br><hr>";
    }
}

Wrap your class with <?php ?> tags. DOH!

[CJPinder]

    function myplatinum()
    {
         $this->attach($this,array('NOTIFIER_CART_ADD_CART_END'));
    } 

Should be...

    function platinum()
    {
        $_SESSION['cart']->attach($this,array('NOTIFIER_CART_ADD_CART_END'));
    } 

...and as you've already worked out, you need the php start and end tags

Oh yeah That too.

Any idea why I can't send echo statements from the update function?

Probably because there's a page redirect happening, which dumps the echo'd data into a black hole. Use die('INFO HERE'); instead of echo() if you want to halt execution and see what's happening. Remember that die() halts execution though.

Yeah. Also, I was using the wrong notifiers. START notifiers aren't going to display anything. END notifiers are the money. Because they signal that data will be usually displayed shortly thereafter.

THANK YOU for the help. Its unlike me to need hand holding. Then again, its unlike me to be a and forget php tags. Just one of those Days!

Hey,

I'm trying to add a product the the session cart. I've found the definition of actionaddproduct, but for the life of me cant find any documentation about what it needs in the param array, or what Im supposed to give $goto.

Anyone care to make an example for me?

Thanks,

Josh
PS On a scary note, I google for application-top.php and some other terms and see a guy with a thread about class problems. Then I look closer, that guy was me. Google sucks up new stuff FAST!
