I am trying to get ID of post on HOME page .So far my coding is

wp_enqueue_script( 'my-ajax-request', get_stylesheet_directory_uri() . '/js/ajax.js', array( 'jquery' ) );
wp_localize_script( 'my-ajax-request', 'MyAjax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
add_action('wp_ajax_nopriv_ajax_request', 'ajax_handle_request');
add_action('wp_ajax_ajax_request', 'ajax_handle_request');

function ajax_handle_request(){
$postID = $_POST['id'];
if (isset($_POST['id'])){
    $post_id = $_POST['id'];
    $post_id = "";

global $post;
$post = get_post($postID);

$response = array( 
    'sucess' => true, 
    'post' => $post,
    'id' => $postID , 

// generate the response
print json_encode($response);

// IMPORTANT: don't forget to "exit"

And My jquery

jQuery(document).ready(function($) {
$('h1.entry-title a').click(function(event) {
var id = $(this).data('id');

  type: 'POST',
  url: MyAjax.ajaxurl,
  data: {'action' : 'ajax_request', 'id': id},
  dataType: 'json',
  success: function(data) {

return false;

But I am getting alert Null instead of getting the id of post.

Please format your codes and content well. For more details check this – Maruti Mohanty Dec 19 '13 at 6:48

You are rendering the json data the wrong way.

Change the success to the below:--

success: function(data) {
    // Now you can similarly render the other details like details.success

Thank you for help But this still alert "Null"...FYI I am trying this on Home page not single post page. – ashraf Dec 19 '13 at 8:50
check if the ajax request is going right... and check if you are getting the response right... You can use a tool like firebug to do it – Maruti Mohanty Dec 19 '13 at 10:19

First, On Chrome or some other browser you could actually check if you get any data from the server by doing "right click => inspect element => network tab".

If your Ajax function is working you should see a GET request. You are using POST type instead try using GET.

Once you see a GET request you also should parse the JSON data using JSON.parse as you were encoding the data in your php function.
