How to display checkbox value in Formit?

Question

MODX

Hi friends. The problem is the following.
The list of services is displayed in the form with checkboxes
The form itself

<section class="application">
    <div class="container">
        <h2>Оставьте заявку</h2>
        
        <form  method="POST" action="">
            <div class="row">
                <div class="col-md-4">
                    <div class="form-group letterName">
                        <label for="fName">Как к вам обращаться<span class="form-required">*</span></label>
                        <span class="error"></span>
                        <input type="text" class="form-control" name="name">
                    </div>
                    <div class="form-group inputnumber">
                        <label for="fNumber">Контактный телефон<span class="form-required">*</span></label>
                        <span class="error"></span>
                        <input type="text" class="form-control form-phone" name="phoneNumber" pattern="^((8|\+7)[\- ]?)?(\(?\d{3}\)?[\- ]?)?[\d\- ]{7,10}$" placeholder="[phone]">
                    </div>
                    <div class="form-group inputemail">
                        <label for="fEmail">E-mail<span class="form-required">*</span></label>
                        <span class="error"></span>
                        <input type="email" class="form-control" name="email" placeholder="[email protected]">
                        <INPUT TYPE="HIDDEN" name="pageurl" VALUE="http://askmeplz.com/" />
                    </div>
                </div>
                <div class="col-md-4">    
                    <div class="form-group question">
                        <label for="fWishes">Напишите что вас интересует</label>
                        <span class="error"></span>
        <textarea aria-required="true" rows="8" cols="45" name="message" id="message" placeholder="Сообщение" value=""></textarea>
                    </div>
                </div>
                 <div class="col-md-4">  
                    <div class="fCheck">
                        <p>Выберите услугу</p>
                        
                    </div>
                </div>
            </div>
            <button type="submit" name="call20" class="btn btn-staro btn-staro-an">Отправить</button>
            <span class="error"></span>
        <label><input type="hidden" name="soglasie[]" value="">
        <input type="checkbox"  name="soglasie[]" value="согласие"  
         onclick="showHide('soglasie-input');" >
        Согласен с политикой<a href=""> конфиденциальности</a></label>
        </form>
    </div>
</section>

The content of inputTpl

<label><input type="hidden" name="[]" value=""><input type="checkbox" value="" name="[]"  onclick="showHide('-input');" ><span></span></label>

It turns out that checkboxes are added with the addition of a new service. But how can I pass in the message chunk the value of the checkbox that the user selected when sending the message.

Answer 1

Everything is quite simple, is added to the name at the end, for example

1
<input name="kreslo0[]" type="checkbox" value="kreslo0">
