Disabling specific times

The simple solution is to use a Select Menu element and just enter the available times as options, instead of using the Time element.

If you want to use the Time element you will need to specify the available times by following the steps below.

Step 1

Add the following code to the theme functions.php file (or create a plugin for it).

add_filter('quform_element_valid_1_3', function ($valid, $value, Quform_Element_Time $element) {    if ( ! in_array($value, my_get_available_times())) {
        $element->setError('This time is not available');
        $valid = false;
    }
 
    return $valid;
}, 10, 3);
 
function my_get_available_times()
{
    return array(
        '09:00', '09:30', '10:00', '10:30', '11:00', '11:30'    );
}
 
add_action('wp_footer', function () {
    printf('<script>var timePickerTimes = %s;</script>', wp_json_encode(my_get_available_times()));
});
add_filter('quform_element_valid_1_3', function ($valid, $value, Quform_Element_Time $element) {
    if ( ! in_array($value, my_get_available_times())) {
        $element->setError('This time is not available');
        $valid = false;
    }

    return $valid;
}, 10, 3);

function my_get_available_times()
{
    return array(
        '09:00', '09:30', '10:00', '10:30', '11:00', '11:30'
    );
}

add_action('wp_footer', function () {
    printf('<script>var timePickerTimes = %s;</script>', wp_json_encode(my_get_available_times()));
});
  • On line 1, replace 1_3 with the Time element unique ID
  • On line 13, change the available times to suit

function my_check_time_available($valid, $value, Quform_Element_Time $element)
{
    if ( ! in_array($value, my_get_available_times())) {
        $element->setError('This time is not available');
        $valid = false;
    }
 
    return $valid;
}
add_filter('quform_element_valid_1_3', 'my_check_time_available', 10, 3); 
function my_get_available_times()
{
    return array(
        '09:00', '09:30', '10:00', '10:30', '11:00', '11:30'    );
}
 
function my_print_available_times()
{
    printf('<script>var timePickerTimes = %s;</script>', wp_json_encode(my_get_available_times()));
}
add_action('wp_footer', 'my_print_available_times');
function my_check_time_available($valid, $value, Quform_Element_Time $element)
{
    if ( ! in_array($value, my_get_available_times())) {
        $element->setError('This time is not available');
        $valid = false;
    }

    return $valid;
}
add_filter('quform_element_valid_1_3', 'my_check_time_available', 10, 3);

function my_get_available_times()
{
    return array(
        '09:00', '09:30', '10:00', '10:30', '11:00', '11:30'
    );
}

function my_print_available_times()
{
    printf('<script>var timePickerTimes = %s;</script>', wp_json_encode(my_get_available_times()));
}
add_action('wp_footer', 'my_print_available_times');
  • On line 10, replace 1_3 with the Time element unique ID
  • On line 15, change the available times to suit

Step 2

Go to Forms → Settings → Custom CSS & JS and at the Custom JavaScript field enter the following code.

    if ($timePicker && window.timePickerTimes) {
        var dates = [], parts;
 
        for (var i = 0; i < timePickerTimes.length; i++) {
            parts = timePickerTimes[i].split(':');
            dates.push(new Date(2000, 0, 1, parseInt(parts[0], 10), parseInt(parts[1], 10)));
        }
 
        $timePicker.setOptions({
            dates: dates
        });
    }
});
jQuery(document).ready(function ($) {
    var $timePicker = $('.quform-field-1_3').data('kendoTimePicker');

    if ($timePicker && window.timePickerTimes) {
        var dates = [], parts;

        for (var i = 0; i < timePickerTimes.length; i++) {
            parts = timePickerTimes[i].split(':');
            dates.push(new Date(2000, 0, 1, parseInt(parts[0], 10), parseInt(parts[1], 10)));
        }

        $timePicker.setOptions({
            dates: dates
        });
    }
});
  • On line 2, replace 1_3 with the Time element unique ID

Step 3

If any of the times are not a multiple of 30, you will need to edit the form and to to the Time element settings, on the Data tab at the option Minute interval enter the number 1 and save the form.
