In that way the smarty variables initialized in prestashop header, footer and content will be available using $prestashop_integration->getTemplateVars() (for example logo_url, logo_image_height, logo_image_width and so on…).
It will be wonderful if the widget could render a single prestashop template (like header.tpl or footer.tpl).
I will add some calls to PrestaShop internal, but the plugin is still compatible with PrestaShop 1.4 and must be kept compatible.
For calling specific PrestaShop template, you generally need to add more variables according to the page examined (produts, categories, a specific product, …). For header.tpl and footer.tpl, you already have the PrestaShop Integration Hook widget, which will be used to put theses templates.
Thanks, do not forget to give a review to the module.
Ops, 1.4 compatibility was not one of my goals. I’m sorry.
Regarding the hooks, they are different from the (customizable) header and footer template files.
I’m not so good at prestashop (maybe due to lack of documentation), but I believe that you could render a single template file using some simple methods from the FrontController (such as setTemplate() and display()).
