Hello,

I'm creating a blog service, and am using PHP with Smarty. I was wondering if it was possible to render a .tpl template from JavaScript?

I have a blogpost.tpl file which outlines what my blogpost looks like.

My code is as follows:
Code:

$(window).scroll(function(){
       // If the user has scrolled the height of the window, load more blog posts
       if($(window).scrollTop() == $(document).height() - $(window).height()){
          $('.ajax_loader_wrapper').css('display', 'block');

          const offset = $("#offset").val();
          $.ajax({
             type: "POST",
             url: 'controllers/get_entries.php',
             data: {
                offset: offset
             },
             success: function(posts){                
                $("#offset").val(offset + 3);

                                // Code to render additional blogposts, preferably from the existing template
                                // TODO
             }
          });
       }
    });


My question is regarding the "TODO" section above. Manually in JS, this logic would involve creating the HTML from scratch and appending it to the bottom, which seems redundant given that I already have a template file that outlines what the HTML would look like. I am also concerned about doing this locally because I have server-side logic in the template (such as checking to see if the user is logged in, and showing Edit/Delete buttons if they are), and this would be a security issue if done locally.

I would much prefer to do this over pagination. I am also set on making this on my own, as opposed to using an existing jQuery plugin.

Thanks in advance! Any advice would be appreciated.

Jake

You have to request a page that returns new batch of elements to your JS.
How do you do that on server(PHP) side is irrelevant to client (JS) side.
