Apply Prestashop Cart to custom Hook - prestashop

Question

First let me explain myself. I'm new to Prestashop Development, I've a background using Wordpress. The thing is, I'm trying to hook 'blockcart.php' to my custom hook 'HOOK_SHOPPINGBAG'. I have tried a lot and after a couple of hours I have decided to just ask the question here.
First I have created the Hook inside ps_hook inside the Prestashop Database. This hook is functioning and Prestashop reads it. After that I have added my new hook to FrontController.php, the code is shown below:
public function initContent()
{
$this->process();
if (!isset($this->context->cart))
$this->context->cart = new Cart();
if (!$this->useMobileTheme())
{
// These hooks aren't used for the mobile theme.
// Needed hooks are called in the tpl files.
$this->context->smarty->assign(array(
'HOOK_HEADER' => Hook::exec('displayHeader'),
'HOOK_TOP' => Hook::exec('displayTop'),
'HOOK_SHOPPINGBAG' => Hook::exec('displayShoppingBag'),
'HOOK_LEFT_COLUMN' => ($this->display_column_left ? Hook::exec('displayLeftColumn') : ''),
'HOOK_RIGHT_COLUMN' => ($this->display_column_right ? Hook::exec('displayRightColumn', array('cart' => $this->context->cart)) : ''),
));
}
else
$this->context->smarty->assign('HOOK_MOBILE_HEADER', Hook::exec('displayMobileHeader'));
}
I also have added the Hook to the second bunch of lines inside FrontController.php:
// Call hook before assign of css_files and js_files in order to include correctly all css and javascript files
$this->context->smarty->assign(array(
'HOOK_HEADER' => $hook_header,
'HOOK_TOP' => Hook::exec('displayTop'),
'HOOK_SHOPPINGBAG' => Hook::exec('displayShoppingBag'),
'HOOK_LEFT_COLUMN' => ($this->display_column_left ? Hook::exec('displayLeftColumn') : ''),
'HOOK_RIGHT_COLUMN' => ($this->display_column_right ? Hook::exec('displayRightColumn', array('cart' => $this->context->cart)) : ''),
'HOOK_FOOTER' => Hook::exec('displayFooter')
));
I want to show the Cart inside header.tpl so I have added the Hook to this file:
<div class="shoppingbag">
{$HOOK_SHOPPINGBAG}
</div>
To make sure Blockcart.php can be hooked to my new hook I have added the following line to blockcart.php:
public function hookShoppingBag($params) {
return $this->hookheader($params, 'displayShoppingBag');
}
I've already tried so many things, but when I try to Hook the module to the new Hook it keeps telling me "This modules can't transplant to this hook!"
Maybe I have just made some stupid mistakes, but anyway I hope you guys can help me. Thanks!

I assume you need a custom hook for blockcart module to be placed somewhere.
This is how to achieve it through Presta's custom hook way.
|| $this->registerHook('shoppingBag') == false
Add this to the module's install method.
public function install()
{
if (
parent::install() == false
|| $this->registerHook('top') == false
|| $this->registerHook('header') == false
|| $this->registerHook('actionCartListOverride') == false
|| Configuration::updateValue('PS_BLOCK_CART_AJAX', 1) == false
|| Configuration::updateValue('PS_BLOCK_CART_XSELL_LIMIT', 12) == false)
|| $this->registerHook('shoppingBag') == false
return false;
return true;
}
Create a public method hookShoppingBag like this.
public function hookShoppingBag($params)
{
return $this->hookProductActions($params);
}
To hook it to any tpl use this.
<div class="shoppingbag">
{hook h='presetWishlist'}
</div>
