Contact Form 7 Plugin (Wordpress) - Catch date from page

Question

I want to insert a contact form on an event, so the user can register to that event. I don't want to generate a contact form for each event, so my idea is to catch the date from a site element

Date:

<span class="ecwd-event-date" itemprop="startDate" content="2017-06-22T18:00">                                        22.06.2017 18:00  - 13.07.2017 21:30                                 </span>

Subject:

<h1 itemprop="name" class="ecwd-events-single-event-title summary entry-title">subject</h1>

Is that possible?

Answer 1

Might be easier to use this plugin https://wordpress.org/plugins/cf7-database/ . This will let you keep a db record of the submission with a timestamp. Rather than the form generating the timestamp, the DB will generate it when the user submits the form.
