php - 在自制的wordpress扰流插件中启用/激活简码

在自制的wordpress spoiler中，shortcutes（ultimate）不起作用
（附：以上是我问题的最初标题。我把它改写成更一般的）
我的问题：
我已经创造了一个自制的扰流器，基于this tutorial。效果很好。然而，shortcodes ultimate的shortcodes在spoiler中不起作用：它只是将源代码显示为纯文本。
我的问题是如何“启用”这些缺点在我的扰流器？
示例：Spoiler unfolded
我的代码：
WP页

[su_button url="http://www.my-url.com/wp-content/uploads/2015/01/fileName.txt" download = "FileName.txt" background="#FF6B53" size="2" icon="icon: download" rel="download = 'fileName'"]download[/su_button]

[dag_spoiler title="My spoiler"]
    [su_button url="http://www.my-url.com/wp-content/uploads/2015/01/fileName.txt" download = "FileName.txt" background="#FF6B53" size="2" icon="icon: download" rel="download = 'fileName'"]download[/su_button]
[/dag_spoiler]

（两个按钮完全相同）

JS源代码

jQuery(document).ready( jQuery(function( $ ) {
    $(".dag_spoiler_header").each(function(){
    $(this).click( function() {
        var help_text_span = $(this).children('span.dag_spoiler_help_text');
        $(this).siblings('.dag_spoiler_content').slideToggle( "slow", function() {
        help_text_span.html(
            help_text_span.html() == '<i class="fa '+hide_text+'"></i>' ? '<i class="fa '+show_text+'"></i>' : '<i class="fa '+hide_text+'"></i>'
        );
        });
    });
    var show_text = $(this).attr('data-dag-spoiler-show');
    var hide_text = $(this).attr('data-dag-spoiler-hide');
    $(this).prepend(' <span class="dag_spoiler_help_text" style="margin-right: 15px; margin-left: 5px; font-size: 14px;"> <i class="fa '+show_text+'"></i></span>');
    });
}));

（只是为了精疲力尽）CSS

.dag_spoiler {
    margin: .5em 0 .5em 0;
}

.dag_spoiler .dag_spoiler_header {
    cursor: pointer;
    font-size: 13px;
    font-weight: bold;
    line-height: 20px;
    min-height: 20px;
    padding-bottom: 7px;
    padding-left: 0;
    padding-right: 7px;
    padding-top: 7px;
    position: relative;
    font-weight: bold;
}

.dag_spoiler .dag_spoiler_header::before {
    font-family: FontAwesome;
    font-weight: normal;
    margin-left: 5px;
    margin-right: 15px;
}

.dag_spoiler div.dag_spoiler_content {
    padding-left: 7%;
    padding-right: 7%;
    display: none;
}

最佳答案

尝试添加

do_shortcode($content)

在你的破坏者的缺点。这样地：
