我正在写一个视频博客。在头版我有一个排序方式选项。您可以在以下链接中尝试该选项
无法确定如何使最短和最长的视频选项正常工作。在db中，我有一个名为“complete”的自定义字段，其值以小数为单位（即4.23、0.26、1.28等，其中4.23=4分23秒）最短视频；我想按照上述十进制值的升序显示视频。
对于最长的视频：希望以降序方式显示视频。
在此方面的任何帮助都将不胜感激。
如何在最短和最长持续时间内使用自定义字段值过滤帖子？

我使用以下代码在前端实现过滤器；
//placed this code in index.php after <?php get_header(); ?>
<?php
$search = isset( $_GET[\'s\'] ) ? $_GET[\'s\']: null;
if( $search ){
$user_filtre .= \'s=\' . $_GET[\'s\'] . \'&\';
}
$filtre = isset( $_GET[\'filtre\'] ) ? $_GET[\'filtre\']: \'date\';
$cat = isset( $_GET[\'cat\'] ) ? $_GET[\'cat\']: 0;
$user_filtre = \'filtre=\' . $filtre . \'&\';
$display = isset( $_GET[\'display\'] ) ? $_GET[\'display\']: get_option( get_theme_name() . \'_type_display\' );
$user_display = \'display=\' . $display . \'&\';
if( ($filtre != null) && ($cat >= 0) ) :
$args = array(
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'post_type\' => \'post\',
\'paged\' => $paged,
);
$tri = null;
switch( $filtre ){
case \'date\' :
$args = array(
\'orderby\' => \'date\',
\'order\' => \'DESC\',
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'paged\' => $paged,
\'cat\' => $cat
);
break;
case \'views\' :
$args = array(
\'meta_key\' => \'post_views_count\',
\'orderby\' => \'meta_value_num\',
\'order\' => \'DESC\',
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'paged\' => $paged,
\'cat\' => $cat
);
break;
//for longest videos
case \'duree\' :
$args = array(
\'meta_key\' => \'complete\', // custom feild storing time in decimal
\'orderby\' => \'meta_value_num\',
\'order\' => \'DESC\',
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'paged\' => $paged,
\'cat\' => $cat
);
break;
//for longest videos
case \'short\' :
$args = array(
\'meta_key\' => \'complete\', // custom feild storing time in decimal
\'orderby\' => \'meta_value_num\',
\'order\' => \'ASC\',
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'paged\' => $paged,
\'cat\' => $cat
);
break;
case \'random\' :
$args = array(
\'orderby\' => \'rand\',
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'paged\' => $paged,
\'cat\' => $cat
);
break;
default:
$args = array(
\'posts_per_page\' => get_option( get_theme_name() . \'_nb_videos_listing\' ),
\'post_type\' => \'post\',
\'paged\' => $paged
);
break;
}
$tri = /*\'\' . __(\'sorted by\', get_theme_name()) . \'\' . */corres_tv( $filtre );
$term = $wp_query->queried_object;
$wp_query = new WP_Query( $args );
?>
<ul class="filtre-list">
