myCredWordPress的插件,可让您轻松创建积分余额并设置用户赚取积分的步骤。

以下是他们的开源插件的链接:

准备好!在这里:我找不到解决方案如何将我自己$amount的添加$current_balance$new_balance

我已经尝试过这样的事情,但没有运气:

add_filter('filter_update_users_balance', 'add_my_own_amount');

function add_my_own_amount($amount){
return 10;
}

让我们看一下mycred-functions.php文件。

首先,它获得了这样的用户余额:(我不确定是否有必要阅读以解决我的问题,我建议现在跳过它:))

     /**
      * Get users balance

     * Returns the users balance unformated.
     *
     * @param $user_id (int), required user id
     * @param $type (string), optional cred type to check for
     * @returns zero if user id is not set or if no creds were found, else returns amount
     * @since 0.1
     * @version 1.4.1
     */
public function get_users_balance( $user_id = NULL, $type = NULL ) {

    if ( $user_id === NULL ) return $this->zero();

    // Type
    $point_types = mycred_get_types();
    if ( $type === NULL || ! array_key_exists( $type, $point_types ) ) $type = $this->get_cred_id();

    $balance = mycred_get_user_meta( $user_id, $type, '', true );
    if ( $balance == '' ) $balance = $this->zero();

    // Let others play
    $balance = apply_filters( 'mycred_get_users_cred', $balance, $this, $user_id, $type );

    return $this->number( $balance );

}
    // Replaces
    public function get_users_cred( $user_id = NULL, $type = NULL ) {

        return $this->get_users_balance( $user_id, $type );

    }

之后它会像这样更新用户余额

在这里,我们有这行代码$new_balance = $current_balance+$amount;,向我们展示了插件如何返回用户的新余额。在代码的最底部,它是return $this->number( $new_balance );这样做的,我们可以稍后根据价值设置用户余额。$new_balance

/**
         * Update users balance
         * Returns the updated balance of the given user.
         *
         * @param $user_id (int), required user id
         * @param $amount (int|float), amount to add/deduct from users balance. This value must be pre-formated.
         * @param $type (string), optional point type key to adjust instead of the current one.
         * @returns the new balance.
         * @since 0.1
         * @version 1.4.2
         */
        public function update_users_balance( $user_id = NULL, $amount = NULL, $type = NULL ) {

            // Minimum Requirements: User id and amount can not be null
            if ( $user_id === NULL || $amount === NULL ) return $amount;

            // Type
            $point_types = mycred_get_types();
            if ( $type === NULL || ! array_key_exists( $type, $point_types ) ) $type = $this->get_cred_id();

            // Enforce max
            if ( $this->max() > $this->zero() && $amount > $this->max() ) {

                $_amount = $amount;
                $amount  = $this->number( $this->max() );

                do_action( 'mycred_max_enforced', $user_id, $_amount, $this->max() );

            }

            // Adjust creds
            $current_balance = $this->get_users_balance( $user_id, $type );
            $new_balance     = $current_balance+$amount;

            // Update creds
            mycred_update_user_meta( $user_id, $type, '', $new_balance );

            // Update total creds
            $total = mycred_query_users_total( $user_id, $type );
            mycred_update_user_meta( $user_id, $type, '_total', $total );

            // Clear caches
            mycred_delete_option( 'mycred-cache-total-' . $type );

            // Let others play
            do_action( 'mycred_update_user_balance', $user_id, $current_balance, $amount, $type );

            // Return the new balance
            return $this->number( $new_balance );

        }

然后它像这样设置用户余额

/**
         * Set users balance
         * Changes a users balance to the amount given.
         *
         * @param $user_id (int), required user id
         * @param $new_balance (int|float), amount to add/deduct from users balance. This value must be pre-formated.
         * @returns (bool) true on success or false on fail.
         * @since 1.7.3
         * @version 1.0.1
         */
        public function set_users_balance( $user_id = NULL, $new_balance = NULL ) {

            // Minimum Requirements: User id and amount can not be null
            if ( $user_id === NULL || $new_balance === NULL ) return false;

            $type        = $this->get_cred_id();
            $new_balance = $this->number( $new_balance );
            $old_balance = $this->get_users_balance( $user_id, $type );

            // Update balance
            mycred_update_user_meta( $user_id, $type, '', $new_balance );

            // Clear caches
            mycred_delete_option( 'mycred-cache-total-' . $type );

            // Let others play
            do_action( 'mycred_set_user_balance', $user_id, $new_balance, $old_balance, $this );

            return true;

        }

最后在mycred-balances.php文件中,我们有:

// Add to the balance
   if ( $method == 'add' )
   $mycred->update_users_balance( $user_id, $balance );

// Change the balance
   else
   $mycred->set_users_balance( $user_id, $balance );

我花了好几个小时才找到解决方案,我想我找不到解决方案,所以如果你能帮我解决这个问题,我将不胜感激。

编辑 :

我想$amount用我的 javascript 变量的值来增加 myCred 的值!我想将 Wordpress 插件的变量(我认为是$amount)分配给 javascript 变量的值,以便将交互式电子学习课程连接到 WordPress myCred 插件,这将是惊人的游戏化体验……!

让我再解释一下:

使用 jQuerypost()方法,我可以将要处理的数据(例如数字 javascript 变量)提交到服务器中的指定 PHP 文件。让我们看看我的代码以了解我想用它做什么:

这是我的 JavaScript 代码:

var speechResult= 10;          
$.ajax({
    url:"https://...Example.php",
    method: "post",
    data: {'speechResult': speechResult},
    success: function(res) {
             console.log(res)
    }
  });

这是我的Example.php中的代码。它只是在控制台中显示SpeechResult值(来自我的 javascript 代码的值!):

<?php
    print($_POST['speechResult'])
?>

如您所见,我有一个名为SpeechResult的 JavaScript 变量,还有一个名为“Example.php”的PHP文件。

通过使用上面的代码,我可以将SpeechResult值传递给Example.php或服务器上的任何其他PHP文件(但不是 myCred 插件的 PHP 文件,因为我不知道如何使用钩子、过滤器、操作等)。

如果我将 **speechResult值传递给$amountmyCred** 中的变量,那么我将根据电子学习 html5 课程中发生的情况来控制向用户提供的奖励积分...

我想传递speechResult值来分配 myCred$amount值...以增加或减少使用的总余额点

我不完全确定,你想要实现什么。也许每个余额都加 10?

您可以在代码中add_filter找到的任何位置使用。apply_filters所以这里例如:

add_filter('mycred_get_users_cred', function($balance, $this, $user_id, $type) {
    return $balance + 10;
});

不确定,如果这有帮助...
