A one-minute introduction to how to add sorting options to WordPress articles

#By default, WordPress only has a sorting options panel for pages. You can use the following code to make articles also have a sorting options panel function.

Add the code to the current theme function template functions.php.

add_action( &#39;admin_init&#39;, &#39;posts_order&#39; );
function posts_order() {
    add_post_type_support( &#39;post&#39;, &#39;page-attributes&#39; );
}

Copy after login

If the front-end wants to implement the article sorting function, it needs to add parameters in the main loop:

$order_posts = new WP_Query(array(
    &#39;post_type&#39; => &#39;post&#39;, 
    &#39;post_status&#39; => &#39;publish&#39;, 
    &#39;orderby&#39; => &#39;menu_order&#39;, 
    &#39;order&#39; => &#39;ASC&#39;, 
) );

Copy after login

The background article list displays the sorting number:

add_action(&#39;manage_posts_custom_column&#39;,  &#39;zm_posts_order_show_columns&#39;);
function zm_posts_order_show_columns($name) {
global $post;
switch ($name) {
case &#39;order&#39;:
$views = $post->menu_order;
echo $views;
break;
}
}
 
add_filter(&#39;manage_posts_columns&#39;, &#39;zm_posts_order_columns&#39;);
function zm_posts_order_columns($defaults) {
$defaults[&#39;order&#39;] = &#39;排序&#39;;
return $defaults;
}

Batch clearing sorting number:

global $wpdb;
$wpdb->query("UPDATE wp_posts SET menu_order = 0 WHERE post_type = &#39;post&#39;");
