I’d like to add some html text before the community submit form, giving users an alert message about our regulations on submitting an event. I see that this is possible on the main calendar view, but it doesn’t show up once the user clicks to submit an event.
You’re right, this is not something you can do via the Add HTML Before Calendar setting. You can however override the relevant template and insert whatever content you like above the form.
Please see our Themer’s Guide and tutorial on template overrides first of all (links at the bottom of this post) but essentially you can copy event-form.php from plugins/the-events-calendar-community-events/views/ and place it in your theme at:
As of v3.7 This is now located in the the-events-calendar-community-events/views/community/modules/header-links.php
* Override this template in your own theme by creating a file at [your-theme]/tribe-events/community/modules/header-links.php
