我们已经创建了一个反馈表单，一旦用户提交了反馈，我们希望运行将其提交给Airtable的函数，然后显示Next按钮。
问题：jQuery运行正常，在提交后显示按钮，但是（isset（$_POST ['submit']）中的函数根本不保存。
我已经看了很多帖子，但找不到答案。任何帮助都是伟大的！
这是我们当前的代码

public function airtable_function() {
        ?>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script type="text/javascript">
            jQuery(document).ready(function(){ 

                jQuery("#nameFrm").submit(function (e) {
                    e.preventDefault();
                    var frm = jQuery('#nameFrm');
                    var outPut = jQuery('#results');
                    var loadButton = jQuery('#loadingImage');

                    var comments = jQuery('#comments').val();
                    var reason = jQuery('#reason').val();

                    jQuery.ajax({
                    type: 'POST',
                        data:'action=submitForm&comments='+comments+'&reason='+reason,
                        url: 'requests.php',

                        },
                        complete: function(data){

                            frm.hide();
                        },
