The server part of the site (management system)?

Question

CMS

Hello! Need Help in developing a fairly complex site, namely: the site should have a convenient and easy-to-use content management system, a simple functional admin panel, with a large database (of goods), filling templates, breakdown of goods into categories, dynamically displaying exchange rates and various dates, multilingualism, site search with various filters, feedback, comments and synchronization with another site, purchase through payment cards, etc.
The site is already almost made in HTML + CSS3 + JS + jquery, but how best to make it dynamic? I would like to hear the advice of an expert)
What is better to learn and use for such tasks and how will it be faster? Or was it better to take some kind of tsms?
My soul lies more with PHP, but I don’t know if everything is implemented on it (I wouldn’t want to use something like joomla, but if there is no way out ....)
Thanks in advance)

Answer 1

If CMS then Drupal or ModX which are more flexible .. Or better a framework in hand and from scratch)
PHP of course will do and some kind of Yii2 / Laravel

Answer 2

I won’t be original - bitrix (but you suffer with multilingualism) or openCart (better derivatives based on it) - here multilingualism is the best, but there may be problems with reliability, well, it’s simpler, it seemed to me like a CMS, but in the essence of a framework did not understand her.

Answer 3

From the words "comfortable", "simple", "functional" - choose two.
If you imagine the site as a big dog: you almost made his skin, and the rest of the body - in fact, is the site. Judging by the Wishlist that you brought from your site, ~ 5% is ready, nothing more.
In any case, you will need to learn something, either cms or a framework. You will also have to either finish the cms for your TK, or write based on the framework.
Look towards PrestaShop
