下面的查询按预期工作，显示按meta\\u值排序的cpt事件，我还没有弄清楚如何删除过去事件或已开始事件的帖子。事件的开始日期当前存储为“yy m d”，并使用jQuery datepicker选择日期。

<?php
global $post;
$args = array(
        \'post_type\' => \'events\',
        \'numberposts\' => 5,
        \'meta_key\' => \'sp_startDate\',
        \'orderby\' => \'meta_value\',
        \'order\' => \'ASC\'
    );
$supplierTrainingEvents = get_posts( $args );
foreach( $supplierTrainingEvents as $post ) :   setup_postdata($post);
?>

$args = array(
\'post_type\' => \'events\',
\'numberposts\' => 5,
\'meta_key\' => \'sp_startDate\',
\'meta_value\' => date("MM d yy"),
\'meta_compare\' => \'>\',
\'orderby\' => \'meta_value\',
\'order\' => \'ASC\'
 );
