如何使Wordpress帖子输出按帖子标题中指定的日期排序？ 以及如何显示标题为> =今天的日期的帖子？

Question

I'm the first time I'm putting out the layout on Wordpress, so I apologize if the question is too simple and obvious:

I have a schedule for the upcoming master classes on the page. And I need the posts to be displayed in ascending order of the date (the date is indicated in the post's title, or, if it is more convinient, I can create a custom date field with the date). Date format is DD.MM.YY

And also, it is necessary that posts with past dates will be not displayed.

Please, tell me how to implement this?

Here is my current code for posts:

<?php
  $args = array(
    'numberposts' => 0,
    'category_name'    => schedule,
    'orderby'     => 'title',
    'order'       => 'ASC',
    'include'     => array(),
    'exclude'     => array(),
    'meta_key'    => '',
    'meta_value'  =>'',
    'post_type'   => 'post',
    'suppress_filters' => true,
  );

  $posts = get_posts( $args );

  foreach($posts as $post){ setup_postdata($post);
      ?>
      <div class="col-md-4 col-sm-6">
        <div class="content-wrapper bg-gray schedule-card">
          <div class="day"><span><?php the_field('week_day') ?></span><span><?php the_title() ?></span></div>
          <a class="event" href="<?php the_field('mc_descr_link_1') ?>"><span class="event-time"><?php the_field('time-mc-1') ?></span><span class="event-name"><?php the_field('mc-1') ?></span></a>
          <a class="event" href="<?php the_field('mc_descr_link_2') ?>"><span class="event-time"><?php the_field('time-mc-2') ?></span><span class="event-name"><?php the_field('mc-2') ?></span></a>
          <a class="event" href="<?php the_field('mc_descr_link_3') ?>"><span class="event-time"><?php the_field('time-mc-3') ?></span><span class="event-name"><?php the_field('mc-3') ?></span></a>
        </div>
      </div>
      <?php
  }

  wp_reset_postdata();
  ?>

Answer 1

It would be better if you create custom field for those date fields. Or you can directly integrate that date field with native "date" field. But if you want to keep them separate from post_date field, then here is what you need to implement:

1. Create some custom field which contains those date values you are telling about. (CUSTOM_FIELD_WHICH_CONTAINS_DATE_VALUE)

2. Change $args array to this:

    $args = array ( 'category_name' => 'schedule', 'orderby' => 'meta_value', 'meta_key'=>'CUSTOM_FIELD_WHICH_CONTAINS_DATE_VALUE', 'order'=>'ASC' 'post_type' => 'post'); 

Note that i have also removed unnecessary arguments from the array above.

Answer 2

If you are using custom field for date:

$today = date('Y-m-d');//date format need to change according to your records
$args = array(
'numberposts' => 0,
'category_name'    => schedule,
'meta_key' => 'CUSTOM_DATE_FIELD_NAME',
'meta_type'=>'DATE',
'meta_query' => array(
    array(
        'key' => 'CUSTOM_DATE_FIELD_NAME',
        'value' => $today,
        'compare' => '>='
    )
),
'orderby' => 'meta_value_date',
'order' => 'ASC'
'exclude'     => array(),
'post_type'   => 'post',
'suppress_filters' => true,

);

Change your CUSTOM_FIELD_DATE format to Ymd Ex:2017-02-27

$today = date('Y-m-d');//Format is 2018-01-28
$args = array(
'post_type'   => 'post',
'post_status'=>'publish',
'meta_key'=>'date_field',
'meta_type'=>'DATE',
'orderby' => 'meta_value',
'order' => 'ASC',
'meta_query' => array(
    array(
        'key' => 'date_field',
        'value' => $today,
        'compare' => '>='
    )
),
);
$posts= new WP_Query( $args ); 
foreach($posts->posts as $post){ setup_postdata($post);
  ?>
  <div class="col-md-4 col-sm-6">
    <div class="content-wrapper bg-gray schedule-card">
      <div class="day"><span></span><span><?=$post->post_title;?></span></div>
    </div>
  </div>
  <?php

}
wp_reset_postdata();
