Could you point me out where this code isn’t working with the update_field option:

HTML
on the button id=”rsvp_button”

PHP (in the functions.php file)
function my_action_callback() {

global $post; // You still may need to pass the POST ID here from the JS ajax.
// get each post by ID
$postID = $post->ID;
// get the post’s custom fields
$custom = get_post_custom($postID);
// find the view count field
$views = intval($custom[‘number_attending’][0]);
// increment the count
if($views > 0) {
update_field($postID, ‘number_attending’, ($views + 1));
} else {
update_field($postID, ‘number_attending’, 1, true);
}
die(); // this is required to return a proper result
}
add_action(‘wp_ajax_my_action’, ‘my_action_callback’);

JS (in the header.php)
<script type=”text/javascript”>
jQuery(‘body’).on(‘click’,’#rsvp_button’,function($){
var data = { action: ‘my_action’ };

$.post(ajaxurl, data, function(response) {
});
});
</script>

For some reason the sets above don’t seem to work.

Any help would be great 🙂
