Calendar with tooltip infos and {{dates}} as source for a dropdown?

About the calendar:

You need to look at functions/wpt_calendar.php. Somewhere near at line 158.
I could implement a filter that would make it easier for you to alter the html of the calendar. But you would still need to implement the popup yourself.

About Contact Form 7:

I have never worked with Contact Form 7, but I did the exact same thing once with Gravity Forms. Here is a snippets of the code that I used:

$events = $wp_theatre->events->load();

$choices = array(array('text' => 'Select an event', 'value' => ' '));
foreach($events as $event){
  $choices[] = array('text' => $event->date(), 'value' => $event->ID);
}

Hi there!

I just released v0.9.4 which has the filters that are needed for your rollover tooltips in the calendar.

To be more specific, you need to use the wpt_calendar_html_day_link filter.

The docs:

@param string  $day_link 	The HTML for the link for the day.
@param string  $day 			The day of the month being displayed in <code>yyyy-mm-dd</code> format.
@param string  $day_url 		The URL to the production page or the listing page.
@param string  $day_label 	The text being shown inside the link for the day.
@param array   $events		An array of WTP_Event objects. The events that take place on the day of the month being displayed.

You can use the $events to add an extra div to $day_link. You can then write some CSS and/or javascript to turn it into a tooltip.

To make it even easier for you to get started I created an example plugin that you can use to write your own plugin. Get it here:

Let me know if this works for you. I would love to get some feedback.

Hi back Jeroen,
thanks a lot for your ongoing work and even more for taking such quick and profound care of my request. I really appreciate that!
Now I’m eager to implement your additional code and shall report the outcome asap.
Best wishes …

Cool! Let me know if you need help. I would love to see this work out and maybe turn it into a blog post.
