Return PHP Variable to Jquery

Question

I have a page called index.php where I have some forms where the user must input information.
On this page I have this JQuery functions.

 else if (result == 3)
 {

     jQuery.get('sample.txt', function(data) {
         alert(data);
     });

 }

where the file sample.text its shown on an alert.

But, I have a page called download.php. When the user click on "submit" at page "index.php" , its send to the page "download.php", the values sent using Ajax POST.

var formData = new FormData($('#form_principal')[0]);
     $("#loading").show();

    setTimeout(function() {
        $.ajax({url: "/tkclientespdo/etiquetaslog/000/0000/download.php",
                  type: "post",

                  data: formData,
                  cache: false,
                  async:true,
                  contentType: false,
                   processData: false,
                  success: function(result)

on page "download.php" i have this variable :

$horaenvio = date("dmYGis");

after this variable i have a code :

echo 3;

that return the function at index.php . but i wanna change 'sample.txt" for the variable "$horaenvio".

someone could help.

If all you seem to be doing with ajax and php is formatting a date, why not just do it in javascript? — Difster

You could return a json string. <?php header('content-type: application/json; charset=utf-8'); echo json_encode(3); — odan

You can use localStorage and storage event or SharedWorker to store the value data at index.php, and get the value at download.php, then .append() data to the FormData object, then echo the proper POST value.
