PHP Cookie不通过AJAX设置

Question

I'm trying to set a PHP cookie via AJAX. I'm putting one variable ("listingID") into the cookie name. If I hard code the name (eg. "cMapPin220") the cookie sets correctly, however I require a variable in the name to identify it.

AJAX:

function myFunc(listingID){

    $.ajax({

        url: 'cookie.php',
        type: 'POST',
        data: {listingID:listingID},
        dataType: 'html'

    }).success(function(data){

        $('.div66').html(data);

    }).fail(function(jqXHR, errMsg) {

        alert("Request failed: " + errMsg);
    });

}

In "cookie.php"

This doesn't work:

<?php
$cookieName = 'cMapPin' . $_POST['listingID'];
setcookie($cookieName, '1', time()+30);
?>

This works:

<?php
$cookieName =   'cMapPin220';
setcookie($cookieName, '1', time()+30);
?>

Your problem is likely in your POST data

data: {listingID:listingID}

You're not quoting the name of your parameter so it's likely pulling the value for both the name and value. Try this instead

data: {"listingID":listingID}
