jQuery variable pass to PHP variable

[shobe089]

hello there. i am having a hard time to debug this problem of mine.i am supposed to retrieve the value from my jQuery and save it in a PHP variable.
$(document).ready(function()
{
$("#months").change(function(event)
{
$.ajax
({
type: 'post',
url: "monthly_CRD.php",
data:
{
"m": $(this).val()
},
success: function(msg)
{
alert(msg);
},
error: function(msg)
{
alert("An error happened: " +msg);
}
});
});

<div>
<select id="months">
<option value='00'>Month...</option>
<option value='01'>Jan</option>
<option value='02'>Feb</option>
<option value='03'>Mar</option>
<option value='04'>Apr</option>
</select>
</div>

<?php
if (isset($_POST['m']))
{
$m = $_POST['m'];
echo $m;
}
?>

it keeps on giving me An error happened: [objectXMLHttpRequest] in my alert box

JQuery = Client
PHP = Server.

In order to get it from jQuery, you'll have to make a post/get to the server, then PHP can retrieve it. It won't happen on initial page load.

You can however use AJAX to post the code on the same page, saving whatever it is you're looking for as a SESSION variable.

I don't have time nor the exact knowledge on how to do it, but I am fairly certain that's your only option.
