在 Prestashop 模块中注册钩子

Question

I am trying to register header hook to display my text:

//install function
return parent::install() &&
            $this->registerHook('header');
public function hookHeader()
    {
        $this->context->controller->addJS($this->_path.'/views/js/front.js');
        $this->context->controller->addCSS($this->_path.'/views/css/front.css');
    }

what that I get when trying to transparent:

Hooks are already registered

Answer 1

I think you should use : actionFrontControllerSetMedia / actionAdminControllerSetMedia to register yours js and css.

public function install()
{
    return parent::install() &&
        $this->registerHook('actionAdminControllerSetMedia');
}
public function hookActionAdminControllerSetMedia()
{
    $this->context->controller->addJS($this->_path.'/views/js/front.js');
    $this->context->controller->addCSS($this->_path.'/views/css/front.css');
}
