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 $currentYear = 0;

$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 ) );

}

}
}
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。
最佳答案
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。

总的来说，我对ruby还比较陌生，我正在为我正在创建的对象编写一些rspec测试用例。许多测试用例都非常基础，我只是想确保正确填充和返回值。我想知道是否有办法使用循环结构来执行此操作。不必为我要测试的每个方法都设置一个assertEquals。例如:describeitem,"TestingtheItem"doit"willhaveanullvaluetostart"doitem=Item.new#HereIcoulddotheitem.name.shouldbe_nil#thenIcoulddoitem.category.shouldbe_nilendend但我想要一些方法来使用
