Mycred 如何显示 “游客推广” 成功个数及指定确认评论执行

* mycred 如何显示 “游客推广” 成功个数：
1， short code 实现方法：
[mycred_total_points ref=”visitor_referral”]
类似：[mycred_total_points ref=”signup_referral”]
查看历史记录：[mycred_history ref=”visitor_referral,signup_referral”]

2， 函数实现方法：

Example 1: Get all references with their count no matter which point type they belong to.

$references = mycred_count_all_ref_instances( -1, 'DESC', 'all' );
if ( ! empty( $references ) ) {
  foreach ( $references as $reference => $count ) {

    echo $reference . ' ' . $count;

  }
}

Example 2: Get the top 10 references for the default point type.

$count = mycred_count_all_ref_instances( 10 )
if ( ! empty( $references ) ) {
  foreach ( $references as $reference => $count ) {

    echo $reference . ' ' . $count;

  }
}

Example 3: Count the number of times a user has received points for approved comments.

$user_id = 1;
$count   = mycred_count_ref_instances( 'approved_comment', $user_id );

$payments = mycred_count_ref_instances( 'woocommerce_payment' );
