使用GET方法不会传输值

Question

Whenever I write echo $_GET['sec']; then it shows the value of sec but when I try the following code:

    $(document).ready(function() {
        setInterval(function () {
            $('#div_id').load('../data.php?id_to=<?php $_GET['sec'];?>')
        }, 100);
    });

The value of "sec", which is coming from another page does not transfer to data.php with id_to variable.

What's wrong with my code?

I can see the value of $_GET['sec']; in current page but the value is not available on the data.php file.

Answer 1

Code is okay so variable if available should be passed

So what can you try is:

You have simple mistake you don't echo

change <?php $_GET['sec'];?> to <?php echo $_GET['sec'];?> or <?= $_GET['sec'] ?>

also:

1. what's the output of this php code is it ile '../data.php?id_to=VALUE' If output is okay then variable will be passed via GET method

2. In your data.php try doing echo $_GET['id_to'] maybe you try to output sec and this causes problem?

3. You can always try print_r($_GET); on data.php
