用于在网站上显示时间发布内容的自定义WordPress发布查询

我正在尝试使用WordPress查询实现一个“内容点播风格/时间发布内容”订阅系统，该查询使用设置的参数从自定义帖子类型中过滤和选择内容，并将其显示在页面模板上。下面包括解释、一些示例、查询的初始参数以及零售商（页面）和帖子的结构。

这是否可能通过WP查询实现，或者是否需要插件？我已经研究过会员插件，但对于这种定制级别来说，它们似乎太过分了。

<?php
/**
 * Pages that are defined as \'Retailers\'.
 * Each retailer (page) will have a defined start date using an Advanced Custom Fields date picker field. This field is set manually by the site admin.

 * The retailer pages will display a defined number of posts from the \'sendouts\' custom post type in a HTML dropdown (explained below).
 * The number of displayed posts is handled in part by the start date parameter.
 * A new post will be added every 14 days (2 weeks).

 * EXAMPLE 1: Retailer A has a start date of January 1, 2019. Counting up from that start date to the current date (January 7, 2020),
 * the retailer will have a total of 26 posts accessible from the HTML dropdown.

 * EXAMPLE 2: Retailer B has a start date of December 1, 2019. Counting up from that start date to the current date (January 7, 2020,
 * the retailer will have a total 2 posts accessible from the HTML dropdown.

 * EXAMPLE 3: Retailer C has a start date of January 1, 2020. As the start date is less than 14 days (two weeks) old, only one post will be displayed
 * and the HTML dropdown will not be displayed on the page.
 *

$startDate = get_field( \'sendout_start_date\' );

Div-Wrap with Functions.php in ChildTheme Using Shorcode！
