How to upload as attachments in email

Question

I am trying to make a form that sends an email with the form inputs and files that the user uploads. The part of sending inputs is already ready, I’m using the Magic Form (Martin M.) in the Octobercms framework, but the function of uploading files from Magic Form does not work, so I’m trying to do it by hand, but so far I have not had any success. The Magic Form "file-multi.htm" file code is this:

<div
class="responsiv-uploader-fileupload style-file-multi is-multi {{ __SELF__.isPopulated() ? 'is-populated' }}"
data-control="fileupload"
data-template="#uploaderTemplate{{ __SELF__ }}"
data-unique-id="{{ __SELF__ }}"
{% if __SELF__.fileTypes %}data-file-types="{{ __SELF__.fileTypes }}"{% endif %}

<!-- Field placeholder -->
<input type="hidden" name="_uploader[{{ __SELF__.attribute }}]" value="" />

<!-- Upload Button -->
<button type="button" class="ui button btn btn-default oc-icon-upload upload-button">
    {{ __SELF__.placeholderText }}
</button>


<!-- Existing files -->
<div class="upload-files-container">
    {% for file in __SELF__.fileList %}
        <div class="upload-object is-success" data-id="{{ file.id }}" data-path="{{ file.pathUrl }}">
            <div class="icon-container">
                {% if file.isImage %}
                    <img src="{{ file.thumbUrl }}" alt="" />
                {% else %}
                    <img src="{{ 'plugins/martin/forms/assets/imgs/upload.png'|app }}" alt="" />
                {% endif %}
            </div>
            <div class="info">
                <h4 class="filename">
                    <span data-dz-name>{{ file.title ?: file.file_name }}</span>
                </h4>
                <p class="size">{{ file.sizeToString }}</p>
            </div>
            <div class="meta">
                <a
                    href="javascript:;"
                    class="upload-remove-button"
                    data-request="{{ __SELF__ ~ '::onRemoveAttachment' }}"
                    data-request-confirm="{{ __SELF__.removeText }}"
                    data-request-data="file_id: {{ file.id }}"
                    >&times;</a>
            </div>
        </div>
    {% endfor %}
</div>
