如何通过第三方插件在Wordpress帖子中制作自定义表单？

Question

我制作了一个自定义表单的子主题。它与我正在使用的插件中的表单具有完全相同的字段（使用Anspress）。我希望用户能够通过我的表单提交。我试图使用POST方法让我的表单发布到插件的问题表所在的PHP文件中。但是，当我点击提交按钮时，没有任何反应。

我能找到某种线索让我入手。我遵循了W3Schools指南，并在这里发现了一个类似的问题，让我想到下面的尝试。

儿童主题的形式

<?php /* Template Name: Main Form */ ?>



<?php get_header(); ?>


<div class="container">
    <div class="row">
        <form action=".../.../.../plugins/anspress-question-answer/includes/ask-form.php" method="POST">
            <div class="col-md-6">

                <div class="form-group">
                    <input id="addtitle" type="text" name="title" class="form-control" placeholder="Title">
                </div>
                <div class="form-group">
                    <textarea class="form-control" rows="3" name="description" id="addquestion" placeholder="Find this for me..."></textarea>
                </div>
                <div class="form-group">
                    <div class="input-group" id="addtags">
                        <input type="text" class="form-control" placeholder="Tags">
                    </div>
                </div>
            </div>
            <div class="row">
                <div class="col-md-12" id="main_submit_div" name="submit_button">
                    <button type="button" class="btn btn-success" id="main_submit_button">Submit</button>
                </div>
            </div>
        </form>
    </div>
</div>
