In a website I use an old commercial theme (not updated anymore).
The theme features a custom post type for Events. So, by clicking the left menu I get to the main Events page, where I find the list of any event (the traditional WP table list).
The problem: since I’m NOT the administrator of the website, I never noticed the table doesn’t sort correctly the posts. To have it working I have to click two times the Date label in the header. I don’t know if this has always been its behavior because I never received any complaint.
I searched anywhere through the files of the theme but I could not find what is causing this issue (moreover, some years ago I made a plugin for this website and the plugin features an identical table that shows no issue).
Apparently, the only thing related to Events is the following (I found it in a theme-init file):
function events_post_register(){$labels = array(
'name' => __('Events', 'taxonomy general name', CORE_THEME_NAME),
'singular_name' => __('Event', CORE_THEME_NAME),
'search_items' => __('Search Events', CORE_THEME_NAME),
'all_items' => __('All Events', CORE_THEME_NAME),
'parent_item' => __('Parent Event', CORE_THEME_NAME),
'edit_item' => __('Edit Event', CORE_THEME_NAME),
'update_item' => __('Update Event', CORE_THEME_NAME),
'add_new_item' => __('Add New Event', CORE_THEME_NAME),
'menu_name' => __('Events', CORE_THEME_NAME)
);
$args = array(
'labels' => $labels,
'singular_label' => __('Events', CORE_THEME_NAME),
'public' => true,
'show_ui' => true,
'show_in_nav_menus' => true,
'hierarchical' => true,
'exclude_from_search' => true,
'capability_type' => 'post',
'query_var' => 'event',
'rewrite' => array(
'slug' => 'event',
'with_front' => false,
),
'menu_icon' => 'dashicons-calendar',
'supports' => array(
'title',
'editor',
'thumbnail',
'excerpt',
'comments',
'custom-fields'
)
);
register_post_type( 'event', $args );
}
Any help is appreciated. 🙂
