Question

所以我在wordpress上有一个带内置日历的插件。

开发人员已说明如何删除选择过去日期的选项，以及您选择的具体日期。

http://support.themecatcher.net/quform-wordpress/guides/advanced/date-validation

我按照说明操作，但也许我错过了一些东西。因为其中只有一个功能一次工作，但从不同时工作。

这是代码。任何帮助将不胜感激。谢谢！

function my_prevent_past_dates($valid, $value, $element)
{
 $time = strtotime("{$value['year']}-{$value['month']}-{$value['day']}");

 if ($time < strtotime('today')) {
      $element->addError('Please choose a date in the future');
     $valid = false;
 }

 return $valid;
}

add_filter('iphorm_element_valid_iphorm_1_6', 'my_prevent_past_dates', 10, 3);

function my_datepicker_prevent_past_dates($options, $dpMinYear, $dpMaxYear, $element)

您可以将my_prevent_past_dates与my_prevent_specific_dates和my_datepicker_prevent_past_dates与my_datepicker_prevent_specific_dates结合使用。

function my_get_dates_to_disable()
{
  return array(
        '2015-05-1',
        '2015-05-2',
       '2015-05-3',
       '2015-05-4',
       '2015-05-5',
     '2015-05-6',
  );
}


function my_prevent_bad_dates($valid, $value, $element)
{
 $time = strtotime("{$value['year']}-{$value['month']}-{$value['day']}");

 if ($time < strtotime('today')) {
     $element->addError('Please choose a date in the future');
     $valid = false;
 } else {
     $disabledDates = my_get_dates_to_disable();
     $submittedDate = "{$value['year']}-{$value['month']}-{$value['day']}"; 

     if (in_array($submittedDate, $disabledDates)) {
          $element->addError('That date is not available');
          $valid = false;
     }     
 }

 return $valid;
}

add_filter('iphorm_element_valid_iphorm_1_6', 'my_prevent_bad_dates', 10, 3);


function my_datepicker_prevent_bad_dates($options, $dpMinYear, $dpMaxYear, $element)
{
  return "{
     minDate: 0,
     maxDate: new Date({$dpMaxYear}, 12 - 1, 31),
     beforeShowDay: function (date) {
       if (quformDisabledDates) {
         for (var i = 0; i < quformDisabledDates.length; i++) {
           var parts = quformDisabledDates[i].split('-');
           if (date.getFullYear() == parts[0] && (date.getMonth()+1) == parts[1] && date.getDate() == parts[2]) {
             return [false];
           }
         }
        }
        return [true];
      }     
    }";
}

add_filter('iphorm_datepicker_options_iphorm_1_6', 'my_datepicker_prevent_bad_dates', 10, 4);

function my_print_dates_to_disable()
{
   ?>
   <script type="text/javascript">
   var quformDisabledDates = <?php echo json_encode(my_get_dates_to_disable()); ?>;
  </script>
   <?php
}
add_action('wp_head', 'my_print_dates_to_disable');

Wordpress插件功能，只有一个有效吗？
