Echo a JS variable into PHP and then insert a PHP file into an HTML element - a step-by-step guide!

Greetings to the wonderful community at stackoverflow,

I am currently working on a variable code that allows for easy insertion of code from another file, such as a div. I am curious if it is possible to include a PHP file using JavaScript and JS variables. While I am aware of how to do this with PHP, I am interested in achieving this through JS.

Here's a snippet of the HTML:

<div id="someId">THE INCLUDE HERE</div>

And here's a piece of the JavaScript:


var tag_id = 'someId'; // retrieved from a database
var url = 'data/includes/code.php'; // also coming from a database

$('#' + tag_id).html('<?php include("' + url + '"); ?>');

It is worth noting that tag_id refers to the ID of an element and the URL is dynamic, sourced from the database.

I have explored and experimented with the following resources (to no avail):

  • send javascript variable to php variable
  • how to print a variable of javascript in php?

I may need to think outside the box on this one. Any guidance or assistance would be greatly appreciated!

(Apologies for any shortcomings in my English...)

Answer №1

It is not possible to directly include a php page using a JS variable, but you can utilize AJAX to fetch the HTML content and insert it into the DOM like this:

$.ajax({
    type: "GET",
    url : "data/includes/code.php",
    success: function(result) {
        $('#' + tag_id).html(result);
    }
});

You can also simplify this by using:

$('#' + tag_id).load(url);
