Guest comments not affecting comment points?

As it stands right now, users must be logged in to get points for comments and the same goes for the authors as myCRED saves the commenters ID as a reference to prevent duplicate points for the same comment.

I will look into changing this somehow in future versions but till then your only option is to hook into the ‘transition_comment_status’ action and/or ‘comment_post’ action and award points to the author if the commenter is not a member.

I’m in desperate need of a fix for this too.

Gabriel can you show us how to hook into these to award points to author if the commenter is not a user. I’m not as knowledgable as you all are with programming.

Here is a basic example that awards 1 point for each approved comment to the content author. You can customize the amount and log template to your liking.

add_action( 'transition_comment_status', array( $this, 'comment_transitions' ), 10, 3 );
function award_points_for_guest_comments( $new_status, $old_status, $comment )
{
	// Look for approved comments
	if ( $new_status != 'approved' ) return;

	// Grab the comment object in case it is not there
	if ( !is_object( $comment ) )
		$comment = get_comment( $comment );

	// Ignore Pingbacks or Trackbacks
	if ( !empty( $comment->comment_type ) ) return;

	// Get post author
	$post = get_post( (int) $comment->comment_post_ID );
	$post_author = $post->post_author;

	// Check if the post author should be excluded
	if ( mycred_exclude_user( $post_author ) === true ) return;

	// Award points to author
	mycred_add(
		'new_comment', // reference
		$post_author, // who to get points
		1, // number of points to award
		'%plural% for new comment on post', // log template to use
		$comment->comment_ID, // save comment id as reference id
		array( 'ref_type' => 'comment' ) // enable support for comment related template tags
	);
}

Wow I’m going to try this out. Cheers for the added comments!

How do I support this plugin? Do you have a paypal donation or similar setup?

Hey Lars.

You can either donate cups of coffee or visit the store.
Thank you in advanced.

This plugin saves me thousands of pounds, so yes, I will support it and so should many others.

I added the code in my function.php file but it did not function. Made a guest comment but nothing was updated in the logs. Did this work for you (using 1.3)?

And when permanently deleting a comment, these warnings are shown:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /public_html/wp-includes/plugin.php on line 406

Warning: Cannot modify header information – headers already sent by (output started at /public_html/wp-includes/plugin.php:406) in /public_html/wp-includes/class-wp-ajax-response.php on line 129

Upps, I see I was a bit to quick in copy pasting. The issue is the hook is incorrect. It should be:

add_action( 'transition_comment_status', 'award_points_for_guest_comments', 10, 3 );

Added your fix but is still not working. Posted guest comment and no update in the logs. Maybe I am doing something wrong?

This is the complete code that I use:

add_action( 'transition_comment_status', 'award_points_for_guest_comments', 10, 3 );
function award_points_for_guest_comments( $new_status, $old_status, $comment )
{
	// Look for approved comments
	if ( $new_status != 'approved' ) return;

	// Grab the comment object in case it is not there
	if ( !is_object( $comment ) )
		$comment = get_comment( $comment );

	// Ignore Pingbacks or Trackbacks
	if ( !empty( $comment->comment_type ) ) return;

	// Get post author
	$post = get_post( (int) $comment->comment_post_ID );
	$post_author = $post->post_author;

	// Check if the post author should be excluded
	if ( mycred_exclude_user( $post_author ) === true ) return;

	// Award points to author
	mycred_add(
		'new_comment', // reference
		$post_author, // who to get points
		1, // number of points to award
		'Guest comment on <a href=%c_post_url%>%c_post_title%</a>', // log template to use
		$comment->comment_ID, // save comment id as reference id
		array( 'ref_type' => 'comment' ) // enable support for comment related template tags
	);
}

A few things to try:

1. Enable WP_DEBUG in your wp-config.php file when you approve a comment to see if you get any error messages.
2. Make sure the post author is not set to be excluded from using myCRED

I enabled WP_DEBUG and it did not show errors, only these warnings:

Warning: session_start(): Cannot send session cache limiter – headers already sent (output started at public_html/wp-content/plugins/w3-total-cache/lib/W3/Cache/Memcached.php:15) in public_html/wp-content/plugins/myqaptcha/myQaptcha.php on line 44

About your second step, I’m not sure what you mean. I have not excluded any users from using myCRED. And I tried guest commenting on more than one post.

Did that code work on your test environment?

Cheers for the support!

I think the issue is that the above code only works if you have setup to approve comments. If a comment is approved without moderation you would need to add more.

Try this (replacing your old code):

if ( function_exists( 'mycred_add' ) ) {
	add_action( 'comment_post',              'award_new_guest_comments', 10, 2 );
	function award_new_guest_comments( $comment_id, $comment_status )
	{
		if ( $comment_status == '1' )
			award_points_for_guest_comments( 'approved', '', $comment_id );
	}
	add_action( 'transition_comment_status', 'award_points_for_guest_comments', 10, 3 );
	function award_points_for_guest_comments( $new_status, $old_status, $comment )
	{
		// Look for approved comments
		if ( $new_status != 'approved' ) return;

		// Grab the comment object in case it is not there
		if ( !is_object( $comment ) )
			$comment = get_comment( $comment );

		// Ignore Pingbacks or Trackbacks
		if ( !empty( $comment->comment_type ) ) return;

		// Get post author
		$post = get_post( (int) $comment->comment_post_ID );
		$post_author = $post->post_author;

		// Check if the post author should be excluded
		if ( mycred_exclude_user( $post_author ) === true ) return;

		// Award points to author
		mycred_add(
			'new_comment', // reference
			$post_author, // who to get points
			1, // number of points to award
			'Guest comment on <a href=%c_post_url%>%c_post_title%</a>', // log template to use
			$comment->comment_ID, // save comment id as reference id
			array( 'ref_type' => 'comment' ) // enable support for comment related template tags
		);
	}
}

THe above code will work both with non-moderated comments and if you manually approve a comment.

And it did! You are a star! Cheers for your hard work, it doesn’t go unnoticed.

Awesome! Ill mark this as resolved.
Let me know if you have any further issues.
