Get the $post array when a scheduled post is made live

Hi all,

Silly problem to have but hopefully you guys can help me solve it.

I have a function that gets called whenever a post is published and it works like a charm except with a scheduled post is made live, the $post variable is empty but, it triggers the code.

The result, is that 99% of the time posts trigger the function correctly. In the rare example of a scheduled post, the function is triggered but with an empty array.

Can anybody suggest where to begin? Neither the $post_id or $post are populated in this one circumstance.

Here’s the code:

function stocktwits_curation_send_report($post_id, $post) {
	//extract data from the post
	extract($_POST);

	//set POST variables
	$fields = array(
				'post'=>urlencode(json_encode($post)),
			);
	//url-ify the data for the POST
	foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
	rtrim($fields_string,'&');

	// do fancy curl stuff here

}

thanks!
