我有一个用于显示日历的类。
我现在想要的是以下内容：如工作日所示，我想超链接类别事件下所有已过帐的日子。
我当时正在考虑在函数中添加循环，以打印出这样的日子：
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 $currentYear = 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++;
}
$monthStartDay= date ( 'N', strtotime ( $this->currentMonthStart) );
$monthEndingDay= date ( 'N', strtotime ( $this->currentYear . '-' . $this->currentMonth . '-' . $this->currentMonthDaysLength) );
if ($monthEndingDay < $monthStartDay) {
$weekLength++;
}
return $weekLength;
}
}
当一个月中的某天有事件发生超链接时，如何运行一个循环来获取事件类别中的所有帖子 注意：该循环还需要处理预定的帖子。
答案 0 :(得分：0)
这需要更多的工作，但是它应该可以帮助您入门。
注意：我将原始的PHPCalendar样式表内联用于测试。
您将必须创建一个$arrDaysPosted索引数组，以包含要使日历链接可单击的信息。现在，它只是存储日期。
