如何获取模态中的数据ID，然后将其传递给ajax？

Question

I'm currently working on a system that has a CREATE EVENT module. Now this CREATE EVENT module allows a user to create events and display it on their profile, and other users can join their event. I used a modal to view further details of an event posted. In the perspective of the one creating the event, the user can publish an event to this so-called "PAST EVENTS" if the event is finished already. I'm having trouble publishing since I cannot figure out how to pass an ID of an EVENT inside a modal.

This is my modal. I used ajax in retrieving and displaying the data.

<div id="readmore" class="modal fade" role="dialog">
    <div class="modal-dialog">
        <!-- Modal content-->
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title" id="event_title"></h4>
            </div>
            <div class="modal-body">
                <div class="row">
                    <div class="col-xs-6">
                        <img id="event_img">
                        <h6>HOW TO GET THERE</h6>
                    </div>
                    <div class="col-xs-6">
                        <p id="event_description"></p>
                        <h6>WHEN</h6>
                        <p id="event_start"></p>
                        <h6>WHO</h6>
                        <p id="occupation"></p>
                        <h6>WHAT TO BRING</h6>
                        <p id="event_material_req"></p>
                    </div>
                </div> 
            </div>
            <div class="modal-footer">
                <a class="btn btn-danger" data-dismiss="modal" onclick="publishToPast()">Publish to Past Activity</a>
                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
            </div>
        </div>
    </div>
</div>

Now what I want is when this <a class="btn btn-danger" data-dismiss="modal" onclick="publishToPast()">Publish to Past Activity</a> will be clicked, it will get the ID of the data in the modal and then update the STATUS of the EVENT on the Database so it can now be displayed on the PAST EVENTS. I was thinking getting it through PHP (through $_SESSION) but I cannot do so, because the modal depends on the number of EVENTS the user will create.

If you have ID when you show the modal just in your onclick function onclick="publishToPast(herePassIDvalue)"
