how to hook into payment?

[kkkyyy 1]

I'm trying to add a hook to my payment page and read out the cart content.

 

I did the following in mymodule.php:

 

 

public function install()

{

if (parent::install() == false OR !$this->registerHook('leftColumn'))

return false;

 

 

 

$this->registerHook('displayPaymentReturn');

$this->registerHook('displayPayment');

$this->registerHook('displayPaymentTop');

$this->registerHook('displayBeforePayment');

$this->registerHook('displayOrderConfirmation');

return true;

}

 

 

 

these were copy-pasted and modified from the tutorial

 

and I defined these hooks

 

public function hookDisplayPaymentReturn( $params )

{

return $this->display(__FILE__, 'displayPayment.tpl');

}

 

public function hookDisplayPayment( $params )

{

return $this->display(__FILE__, 'displayPayment.tpl');

}

 

public function hookDisplayPaymentTop( $params )

{

return $this->display(__FILE__, 'displayPayment.tpl');

}

 

public function hookDisplayBeforePayment( $params )

{

return $this->display(__FILE__, 'displayPayment.tpl');

}

 

public function hookOrderConfirmation( $params )

{

return $this->display(__FILE__, 'displayPayment.tpl');

}

 

 

 

 

 

but through the payment process, none of my content showed up.

the other hooks work fine (for example on the left column)

 

so where is my error?

 

thanks
