如何在橙色HRM中添加自定义输入字段(添加空缺部分）

我需要在橙色hrm的"添加空缺"部分中添加自定义归档的文本框（技能）。

我正在尝试以下代码。它显示在表单中归档的文本，但不添加到数据库中。

orangehrm-3.1''symfony''plugins''orangehrmRecruitmentPlugin''modules''recruitment''templates''addJobVacancySuccess.php

法典：-

<?php
use_stylesheet(plugin_web_path('orangehrmRecruitmentPlugin', 'css/addJobVacancySuccess'));
use_javascript(plugin_web_path('orangehrmRecruitmentPlugin', 'js/addJobVacancySuccess'));
?>
<div class="box" id="addJobVacancy">
    <div class="head">
        <h1><?php echo isset($vacancyId) ? __('Edit Job Vacancy') : __('Add Job Vacancy'); ?></h1>
    </div>
    <div class="inner">
        <?php include_partial('global/flash_messages'); ?>
        <form name="frmAddJobVacancy" id="frmAddJobVacancy" method="post">
            <?php echo $form['_csrf_token']; ?>
            <?php echo $form["hiringManagerId"]->render(); 
            ?>
            <fieldset>
                <ol>
                    <li>
                        <?php echo $form['jobTitle']->renderLabel(__('Job Title') . ' <em>*</em>'); ?>
                        <?php echo $form['jobTitle']->render(array("maxlength" => 50)); ?>
