按自定义字段值排序的表中的循环发布

我正在尝试为自定义post类型的事件生成一个表，其中有几个自定义字段，其中之一是日期。我想在表中显示帖子，并按日期值排序。这是我的代码：

Date format: 2015年7月7日（日/月/年）

目前，循环不起作用，我不知道如何按日期订购。

<div class="container">
  <div class="row">

        <table>
          <tr>
            <th>Artista</th>
            <th>Fecha</th>
            <th>Ciudad</th>
            <th>Información</th>
          </tr>
        <?php $i = 0;?>
        <?php while ( have_posts() ) : the_post(); ?>
            <?php if($i == 0){ echo "<tr>"; }?>
                <td><?php the_title(); ?></td>
                <td><?php the_field(\'fecha_del_evento\'); ?></td>
                <td><?php the_field(\'lugar_del_evento\'); ?></td>
                <td><?php the_content(); ?></td>
            <?php $i++;?>
            <?php if($i == 4){ echo "</tr>"; $i=0;}?>
        <?php endwhile; ?>
            <?php if($i < 4) echo \'</tr>\'; ?>
        </table>

        <?php else:  ?>
          <div class="page-header"><h1>Uh Oh!</h1></div>
