How do hook Authenticating login buttons in 1.3beta fast checkout?
Hi, good question.
Can you add some hookvariable into public_html/extensions/fast_checkout/storefront/view/default/template/responses/checkout/login.tpl
for example
<?php echo $this->getHookVar('login_extension'); ?> at the end of file
And then try to call $that->view->addHookVar('login_extension', '<button>custombtn</button>');
inside your hook onControllerResponsesCheckoutPay_InitData()
where $that = $this->baseObject;
Hope this helps.
Please show us result and we'll include your solution into release
