How can I go about passing data from one php file to another via JavaScript

data_from_here.php

<?php

    $guid = 99;

    require_js('javascript_file.js');

javascript_file.js

require(['elgg/Ajax'], Ajax => {

    var ajax = new Ajax();

    $('.glyphicon-zoom-in').click(function(event) {
        ajax.view('root/data_to_here', {
            data: {
                guid: 99 // Save the $guid from data_from_here.php in here
            },
        }).then(body => {
            $( '.full-image-view' ).html(body);
        })
    });
});

data_to_here.php

<?php

    echo $guid;

The fact that php is always execute before the page is delivered, it permets you to write php code in the javascript.

for that include the javascript as a javascript_file.js.php or write the javascript in a section of the php file.

data_from_here.php

$guid = 99;

require_once('javascript_file.js.php');

javascript_file.js.php

require(['elgg/Ajax'], Ajax => {

  var ajax = new Ajax();

  $('.glyphicon-zoom-in').click(function(event) {
    ajax.view('root/data_to_here', {
        data: {

Here we write the value in php

            guid: <?php echo $guid?> // Save the $guid from data_from_here.php in here
        },
    }).then(body => {
        $( '.full-image-view' ).html(body);
    })
  });
});

data_to_here.php

<?php

    echo $_GET['guid'];
?>
