Contact form 7 Datepicker, date range between 2 dates - wordpress

Question

I would like to have two date field in my Wordpress contact form 7. A start-date and an end-date. The fields will be datepickers from the "Contact Form 7 Datepicker" plugin.
When visitor has selected a start-date he should only be able to select an end date that is 4 days later then the start-date.
How can I achieve this by only using the "contact form 7" form creator?

Answer 1

This is the syntax I put in the "contact form 7".
Start date charter*:
[date* date-start date-format:MM_d_yy]
End date charter*:
[date* date-end date-format:MM_d_yy]
And I added this code to the end of the functions file of the Wordpress theme.
function calendar_js(){
?>
<script>
jQuery(function($){
var start = $('.date-start input').first();
var end = $('.date-end input').first();
start.on('change', function() {
var start_date = $(this).datepicker('getDate');
start_date.setDate(start_date.getDate() + 3);
end.datepicker('option', 'minDate', start_date);
});
});
</script>
<?php
}
add_action('wp_footer', 'calendar_js');
Now the second date picker must be at least 4 days later then the first date picker.

May be this plugin will help you. This plugin works along with CF 7
http://wordpress.org/plugins/contact-form-7-datepicker/
And you can add your own javascript for date manipulation after adding datepicker in CF 7.
Example:
jQuery(document).ready(function($) {
$( ".from" ).datepicker({
onClose: function( selectedDate ) {
$( "#to" ).datepicker( "option", "minDate", selectedDate );
}
});
$( ".to" ).datepicker({
onClose: function( selectedDate ) {
$( "#from" ).datepicker( "option", "maxDate", selectedDate );
}
});
});

2021 Update: Contact form 7 datepicker was removed from wordpress repository due to security reasons

You can try the WP-Datepicker by Fahad Mahmood

Answer 4

This is my solution without the use of plugins,
this is the code of the CF7 fields:
Start date charter *:
[date* date-start]
End date charter *:
[date* date-end]
this is the code added in the functions.php file:
add_action('wp_footer', 'calendar_js');
function calendar_js()
{
?>
<script>
jQuery(function($)
{
var start = $('.date-start input').first();
var end = $('.date-end input').first();
start.datepicker ({dateFormat: 'yy-mm-dd', beforeShow: function() { $(this).datepicker('option','maxDate',end.datepicker('getDate')); } });
end.datepicker ({dateFormat: 'yy-mm-dd', beforeShow: function() { $(this).datepicker('option','minDate',start.datepicker('getDate')); } });
});
</script>
<?php
}

There is no way to achieve it with the form builder directly, but with a bit of JavaScript you can validate the second input field to get your desired behaviour.
Here is an example, that falls back to the earliest date possible once a date is selected, that is out of scope.
<input type=date class=c-date-start>
<input type=date class=c-date-end>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!-- Add the below code to the page your form is located -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.4/moment.min.js"></script>
<script>
jQuery(($) => {
const dateStart = $('.c-date-start')
const dateEnd = $('.c-date-end')
const minBuffer = 4
// Only allow dates in date end field that are after the date start field plus the minimum buffer
dateEnd.on('change', () => {
const startDate = dateStart.val()
const endDate = dateEnd.val()
if (startDate && endDate) {
const startDateMoment = moment(startDate)
const endDateMoment = moment(endDate)
const minDate = startDateMoment.clone().add(minBuffer, 'days')
if (endDateMoment.isBefore(minDate)) {
dateEnd.val(minDate.format('YYYY-MM-DD'))
}
}
})
})
</script>
On WordPress, you probably do not need to load jQuery extra and for the form markup you can add the classes in the CF7 builder like so:
[date date-427 class:c-date-start]
[date date-427 class:c-date-end]
Change the selectors and the minimum timespan according to your needs by adjusting the following declarations inside the source:
const dateStart = $('.c-date-start')
const dateEnd = $('.c-date-end')
const minBuffer = 4
