Hello guys,
I made a code to save the comments given by user and show them in front end, that's running totally fine, and also showing total number of comments given in a topic (actually I am making a blog) but as user save any comment total number of comments is not updating because its using old snippet code not the updated one, once I clear the cache or save the snippet from manager total comments shows fine. So I thought to put the code which will clear the cache after submitting comment and I put that but its not working, I mean as I post the comment my page goes blank, I don't know what wrong I am doing. Below is my code:

<?php
	function clear_cache()
	{
		global $modx;
		include_once($modx->config['base_url'] . "manager/processors/cache_sync.class.processor.php");
		$sync = new synccache();
		$sync->setCachepath($modx->config('base_url') . "assets/cache/");
		$sync->setReport(false);
		$sync->emptyCache();
		$modx->clearCache(); // double clear cache
	}
	
	$path = MODX_CORE_PATH . 'components/blog_comment/';
	$result = $modx->addPackage('blog_comment',$path . 'model/','da_');
	if (! $result) {
	  return 'failed to add package';
	} else {
	  $output = '<p>added Package</p>';
	}
	/* CreateQuote Snippet */
	
	if (isset($_POST['submitbtn'])) {
		/* Form has been submitted */
		/* You might want to check for empty required fields here */
		$blog_comment = $modx->newObject('BlogComment');

		/* the next three lines can be in any order */
		$blog_comment->set('resource_id', $_POST['blog_id']);
		$blog_comment->set('commenter_name', $_POST['commenter_name']);
		$blog_comment->set('commenter_email', $_POST['commenter_email']);
		$blog_comment->set('comment_text', $_POST['commenter_text']);

		$blog_comment->save();
		$modx->clear_cache();
	}
	
	/* Not a repost, just display the form */
	if (isset($_POST['submitbtn'])) 
		$output_form = '<span class="success_message">Comment inserted successfully</span>';
	else
		$output_form .= "";
	$output_form .= $modx->getChunk('comment_area');
	$current_blog = $modx->resource->get('id');
	$comments = $modx->getCollection('BlogComment', array('comment_status'=>'1', 'resource_id'=>$current_blog));
	$total_comments = count($comments);
	$output_comment = "";
	
	if($total_comments)
	{
		$output_comment .= '<ul class="blog_comment_list">';
			foreach($comments as $comment) {
				$fields = $comment->toArray();
				$fields['comment_date'] = date("dS F, Y", strtotime($fields['comment_date']));
				$output_comment .= $modx->getChunk('comment_list', $fields);
			}
		$output_comment .= '</ul>';
	}
	else
		$output_comment .= '<span class="no_comment_msg">Be the first to comment</span>';
	$output = $output_form.$output_comment;

	return $output;

Please help.
