php - 如何超链接有帖子的日历日

Question

我有一个用于显示日历的类。

我现在想要的是:显示工作日时，我想超链接在类别事件下发布的所有日期。

我正在考虑在打印日期的函数中添加循环:

function getWeekDays() {
    $args = array(
        'post_type' => 'post', // the post type
        'category_name' => 'events', // name of category
        'meta_query' => array(
            array(
            'key' => 'field_name', // the name of the custom date field
            'value' => '20190715', // the date to compare it with
            'compare' => '='
            )
        ),
    );
    $events_dates = new WP_Query( $args );

    $weekLength = $this->getWeekLengthByMonth ();
    $firstDayOfTheWeek = date ( 'N', strtotime ( $this->currentMonthStart ) );
    $weekDays = "";
    for($i = 0; $i < $weekLength; $i ++) {
        for($j = 1; $j <= 7; $j ++) {
            $cellIndex = $i * 7 + $j;
            $cellValue = null;
            if ($cellIndex == $firstDayOfTheWeek) {
                $this->currentDay = 1;
            }
            if (! empty ( $this->currentDay ) && $this->currentDay <= $this->currentMonthDaysLength) {
                $cellValue = $this->currentDay;
                $this->currentDay ++;
            }
            $weekDays .= '<li>' . $cellValue . '</li>';
        }
    }
    return $weekDays;
}

整个类如下所示:

<?php
class calendarWidget{
    private $weekDayName = array ("MON","TUE","WED","THU","FRI","SAT","SUN");
    private $currentDay = 0;
    private $currentMonth = 0;

    private $currentMonthStart = null;
    private $currentMonthDaysLength = null; 

    function __construct() {

        $this->currentYear = date ( "Y", time () );
        $this->currentMonth = date ( "m", time () );

        if (! empty ( $_POST ['year'] )) {
            $this->currentYear = $_POST ['year'];
        }
        if (! empty ( $_POST ['month'] )) {
            $this->currentMonth = $_POST ['month'];
        }
        $this->currentMonthStart = $this->currentYear . '-' . $this->currentMonth . '-01';
        $this->currentMonthDaysLength = date ( 't', strtotime ( $this->currentMonthStart ) );
    }

    function getCalendarHTML() {
        $calendarHTML = '<div id="calendar-outer">'; 
        $calendarHTML .= '<div class="calendar-nav">' . $this->getCalendarNavigation() . '</div>'; 
        $calendarHTML .= '<ul class="week-name-title">' . $this->getWeekDayName () . '</ul>';
        $calendarHTML .= '<ul class="week-day-cell">' . $this->getWeekDays () . '</ul>';        
        $calendarHTML .= '</div>';
        return $calendarHTML;
    }

    function getCalendarNavigation() {
        $prevMonthYear = date ( 'm,Y', strtotime ( $this->currentMonthStart. ' -1 Month'  ) );
        $prevMonthYearArray = explode(",",$prevMonthYear);

        $nextMonthYear = date ( 'm,Y', strtotime ( $this->currentMonthStart . ' +1 Month'  ) );
        $nextMonthYearArray = explode(",",$nextMonthYear);

        $navigationHTML = '<div class="prev" data-prev-month="' . $prevMonthYearArray[0] . '" data-prev-year = "' . $prevMonthYearArray[1]. '"><</div>'; 
        $navigationHTML .= '<span id="currentMonth">' . date ( 'M ', strtotime ( $this->currentMonthStart ) ) . '</span>';
        $navigationHTML .= '<span contenteditable="true" id="currentYear">'.    date ( 'Y', strtotime ( $this->currentMonthStart ) ) . '</span>';
        $navigationHTML .= '<div class="next" data-next-month="' . $nextMonthYearArray[0] . '" data-next-year = "' . $nextMonthYearArray[1]. '">></div>';
        return $navigationHTML;
    }

    function getWeekDayName() {
        $WeekDayName= '';       
        foreach ( $this->weekDayName as $dayname ) {            
            $WeekDayName.= '<li>' . $dayname . '</li>';
        }       
        return $WeekDayName;
    }

    function getWeekDays() {            
        $weekLength = $this->getWeekLengthByMonth ();
        $firstDayOfTheWeek = date ( 'N', strtotime ( $this->currentMonthStart ) );
        $weekDays = "";
        for($i = 0; $i < $weekLength; $i ++) {
            for($j = 1; $j <= 7; $j ++) {
                $cellIndex = $i * 7 + $j;
                $cellValue = null;
                if ($cellIndex == $firstDayOfTheWeek) {
                    $this->currentDay = 1;
                }
                if (! empty ( $this->currentDay ) && $this->currentDay <= $this->currentMonthDaysLength) {
                    $cellValue = $this->currentDay;
                    $this->currentDay ++;
                }
                $weekDays .= '<li>' . $cellValue . '</li>';
            }
        }
        return $weekDays;
    }

    function getWeekLengthByMonth() {
        $weekLength =  intval ( $this->currentMonthDaysLength / 7 );    
        if($this->currentMonthDaysLength % 7 > 0) {
            $weekLength++;

如果当天有事件，当超链接一个月中的任何一天时，我如何运行一个循环来获取事件类别中的所有帖子注意:该循环还需要适用于预定的帖子。

Answer 1

这需要做更多的工作，但它应该能让您入门。

注意:我在测试中包含了原始的 PHPCalendar 样式表。

您将必须创建一个 $arrDaysPosted 索引数组来包含您想要使日历链接可点击的信息。现在，它只存储一天。
