Get dynamic start date of an event

Hi! Yes, you’ll likely need to use a custom shortcode to format it the way you want, something like this:

/**
 * Get Event Start Date in Custom Format
 * 
 * Custom shortcode for Contact Form 7 - Dynamic Text Extension
 *
 * @see https://projectdmc.org/support/topic/get-dynamic-start-date-of-an-event/
 * @see https://www.php.net/manual/en/datetimeimmutable.createfromformat.php
 *
 * @return string The event's start time formatted as d.m.Y H:i or an empty string on failure.
 */
function jumpinsteph_event_start_date()
{
    // Call the CF7_get_custom_field function directly, returns date formatted as YYYY-MM-DD HH:mm:ss
    $start_date = wpcf7dtx_get_custom_field(array('key' => '_EventStartDate'));
    if ($start_date) {
        // Convert string to DateTime object
        $start_date = date_create_from_format('Y-m-d H:i:s', $start_date, new DateTimeZone(wp_timezone_string()));
        if ($start_date !== false) {
            // Return with desired format
            return $start_date->format('d.m.Y H:i');
        }
    }
    return ''; // Return empty string on failure
}
add_shortcode('jumpinsteph_event_start_date', 'jumpinsteph_event_start_date');

And then in your form template, simply use [dynamic_text debutformation "jumpinsteph_event_start_date"]

Let me know if that works for you!
