在函数内部时，WordPress查询失败

Question

我正在尝试将ai1ec-events表连接到自定义帖子类型。我在函数之外工作但在内部失败。

这是整个功能。

session_start();
unset($_SESSION['counter']);
if (!isset($_SESSION['counter'])) {
$_SESSION['counter'] = 1;
} else {
$_SESSION['counter']++;
}

if (!isset($_SESSION['current'])) {
$_SESSION['current'] = strtotime(date('F j, Y'));
$_SESSION['current'] = strtotime('+1 day', $_SESSION['current']);
} else {

$_SESSION['current'] = strtotime('+1 day', $_SESSION['current']);
}


function my_ajax_pagination() {
$newDate = $_SESSION['current'];

?>



<div class="day_events <?php if ($_SESSION['counter'] == 0) {echo 'today';} elseif ($_SESSION['counter'] == 1) {echo 'tomorrow';} ?>">

<div>

<div class="day">
<?php if ( $_SESSION['counter'] == 0 ): ?><h3>Today</h3><?php elseif ($_SESSION['counter'] == 1): ?><h3>Tomorrow</h3><?php endif; ?>

<p><?php $curr = date('l', $newDate); echo $curr; ?></p>
<p><?php $curr = date('F j', $newDate); echo $curr; ?></p>
</div>

<div class="events">
<?php 
$ns_time = date('Ymd');
$two_weeks = strtotime('+13 day', $ns_time);
$stargs = array(
'post_type' => 'film',
'posts_per_page' => -1,
'meta_query' => array(
'relation'      => 'OR',
array(
'relation'  => 'AND',
array(
'key'       => 'film_start',
'compare'   => '<=',

'compare'   => '>=',
'value'     => $ns_time,

array(

array(

array(

)
),

$shows = new WP_Query($stargs);

我承认我对此很陌生......这可能就是我为什么难以接受的原因，这可能就是为什么代码按原样编写的原因。

我感谢任何人都能提供的任何帮助。几乎可以打开所有输入。

感谢。
