Website in php how to connect the metric?

Question

PHP

Hello everyone, please help, you need to connect the metric to the site and set goals (javascript event), but before that I only dealt with html, and I am familiar with the site structure (on html). But here you need to connect the metric, they gave me FTP and access to the site, and when I went through Filezilla, I saw it and I don’t understand anything at all, I can’t find the html and css I’m used to :( Guys, thanks to everyone who responded in advance

Answer 1

I don't know how relevant this is.
but, apparently, you have a site on cms prestashop.
in the themes folder there is a folder with the theme used, for example, default.
which theme is used, you can specify in the admin panel.
edit the footer.tpl file there

Answer 2
