Adding unique dates

Hi @carcayu80

I hope you are doing well.

I am afraid it may require some coding, before we ping our developers to verify if there is any workaround let me verify if we are on the same page.

Your calendar will show up as available dates, Tuesdays and then the first Friday of May and the second last Sunday of the year, all other dates will be unavailable correct?

Correct. And It can be only done now selecting tuesdays, fridays and sundays as available weekdays and then manually blocking a lot of days for frdays and sundays

Hi @carcayu80

Thank you for confirmation!

At the moment – you are right, the only way would be to select Tuesdays, Fridays and Sundays as available days and then add exception dates manually. That would work well, I believe, for a year or two (if these are only two days over a years) but if you want that to be “infinite” then automating it would be better.

I’m not sure, though, if that’d be easy to achieve. It would require custom code and finding out the “first Friday of May” and “2nd last Sunday” of a year for each year isn’t very difficult with PHP too but then this needs to be applied to datepicker and what I’m not sure is – if we can use any existing filter hook for this or if it requires changes in plugin code.

I have asked our developers about it and we’ll update you here once we got response.

Note please: our developers are dealing with a lot of complex tasks on daily basis so their response time might be a bit longer than ours. But we’ll let you know here.

Best regards,

Hi @carcayu80,

Could you please try the following snippet and then check whether it helps?

<?php

add_action( 'forminator_before_form_render', 'wpmudev_disable_specific_dates', 10, 5 );
function wpmudev_disable_specific_dates( $id, $form_type, $post_id, $form_fields, $form_settings ){
	if( $id != 361 ){
		return;
	}

	$update = false;
	$form_meta = get_post_meta($id, 'forminator_form_meta', true);
	if( $form_meta ){
		if( isset( $form_meta['fields'] ) ){
			foreach( $form_meta['fields'] as $form_key => $form_val ){
				if( $form_val['id'] == 'date-1' ){
					
					$timestamp = strtotime(date('Y')."-05-00 first friday");
					$first_friday = date("m/d/Y", $timestamp);

					$second_timestamp = strtotime(date('Y', strtotime('+1 year'))."-01-00 first sunday -14 days");
					$second_last_sunday = date("m/d/Y", $second_timestamp);

					if( is_array( $form_meta['fields'][$form_key]['disabled-dates'] ) ) {
						if( in_array( $first_friday, $form_meta['fields'][$form_key]['disabled-dates'] ) ) {
							return;
						}

						if( in_array( $second_last_sunday, $form_meta['fields'][$form_key]['disabled-dates'] ) ) {
							return;
						}
					}

					if( $first_friday ){
						$form_meta['fields'][$form_key]['disabled-dates'][] = $first_friday;
						$update = true;
					}
					
					if( $second_last_sunday ){
						$form_meta['fields'][$form_key]['disabled-dates'][] = $second_last_sunday;
						$update = true;
					}
				}
			}
		}

		if( $update ) {
			update_post_meta($id, 'forminator_form_meta', $form_meta);
		}

	}
	add_filter( 'forminator_field_date_markup', 'wpmudev_disabled_dates_specified', 10, 3 );
}

function wpmudev_disabled_dates_specified( $html, $field, $cls ) {
	if( $field['element_id'] == 'date-1' ){
		$disabled_dates = array();
		$timestamp = strtotime(date('Y')."-05-00 first friday");
		$first_friday = date("m/d/Y", $timestamp);

		$second_timestamp = strtotime(date('Y', strtotime('+1 year'))."-01-00 first sunday -14 days");
		$second_last_sunday = date("m/d/Y", $second_timestamp);
		$disabled_dates[] = $first_friday;
		$disabled_dates[] = $second_last_sunday;
		$disabled_date = implode( ',', $disabled_dates );
		if( strpos( $html, 'data-disable-date=""') !== false ){
			$html = str_replace('data-disable-date=""', "data-disable-date=$disabled_date", $html);
		}
	}
	return $html;
}

In the above code you’ll need no update the number 361 in the following line:
if( $id != 361 ){

To your form ID, suppose your form ID is 123, then the above line will change to:
if( $id != 123 ){

You can implement the above code as a mu-plugins. Please check this link on how to implement the above code as a mu-plugins:
https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

Once the above code is applied, it should update the “Disabled Dates” in the “Datepicker” field.

Kind Regards,

Hello @carcayu80 ,

We haven’t heard from you for several days now, so it looks like the above code snippet worked for you.

Feel free to re-open this ticket if needed.

Kind regards
