Load php file with jquery

Question

Hello,

First of all I apologize if the question is not well structured.

I’m building a content/stock and similar management system.. I leave below a print screen where I try to explain how this structured folders/ directories.

In the index.php file I have the following:

<?PHP
require_once('sistema/functions.php');
require_once('control/head_load_script.php');
corpo_main();
require_once('control/footer.php');
?>

In the root/system/functions.php file I have the following functions:

function getLang(){
  if(!empty($_SESSION['usuarioID'])  == '' ){
    if(isSet($_GET['lang'])){
      $lang = $_GET['lang'];

      $_SESSION['lang'] = $lang;
      setcookie("lang", $lang, time() + (3600 * 24 * 30));
    } else if(isSet($_SESSION['lang'])){
      $lang = $_SESSION['lang'];
    } else if(isSet($_COOKIE['lang'])){
      $lang = $_COOKIE['lang'];
    } else{
      if(getSystemInfo('site_lang') == ''){
        $lang = "pt";
      } else {
        $lang = getSystemInfo('site_lang');
      }
    }
    include_once 'lang/lang.'.$lang.'.php';
  } else {
    $lang = getuserinfo('lang');
    include_once 'lang/lang.'.$lang.'.php';
  }
  DEFINE('langTag', $lang);
}
getLang();

function corpo_main(){
  if (!isset($_SESSION['usuarioID'])) {
    session_destroy();
    require_once('control/login.php'); 
  } else {
    require_once('control/header.php');
    require_once('control/corpo.php');
  } 
}

In root/lang/lang.pt.php or lang.en.php I have the following: (among other translations)

DEFINE('users','Utilizadores');

In the root/js/main.js file I have:

getPage = function(page,title){
  $("#main-panel-body").empty();
  $( "#main-panel-body" ).load( "control/loader.html" );
  setTimeout(function(){
    $( "#main-panel-body" ).load( "sistema/corpos/"+page+".php" ); 
    $("#main-panel-body").empty();
  }, 2000); 
  document.title = title;
}

In the control/body.php file, I have a DIV With the main-panel-body ID, when I replace the contents of this div, through the jquery I show above, by the contents of the root/system/bodies/users.php file, does not load the php variables that the users.php file has, as for example translation variables. Issues an error.

I leave down the error:

Warning: Use of Undefined Constant users - assumed 'users' (this will throw an Error in a Future version of PHP) in

What am I doing wrong?

Thank you.

Hello, good night!

So this is not actually a MISTAKE, but a warning from Attention, you are probably using a version PHP that does not accept but the definition of constants in this way.

Current code example:

<?php
define("title", "Stack Overflow");
echo constant("title");
