保存 Wordpress 自定义元信息

Question

nwt_home_section_header_io我用来保存自定义元框的代码根本不起作用，你能告诉我哪里出错了吗？目前它只保存一个单选按钮，因此数组中只有一个条目。

谢谢

function save_nwt_home_section_settings_meta($post_id, $post) {
    // Is the user allowed to edit the post or page?
    if ( !current_user_can( 'edit_post', $post->ID ))
        return $post->ID;

    // OK, we're authenticated: we need to find and save the data
    // We'll put it into an array to make it easier to loop though.

    $nwt_home_section_settings_array = array(
        'nwt_home_section_header_io' => $_POST['nwt_home_section_header_io']
    );

    // Add values of $events_meta as custom fields
    foreach ($nwt_home_section_settings_array as $key => $value) { // Cycle through the $events_meta array!

        if( $post->post_type == 'revision' ) return; // Don't store custom data twice

            update_post_meta($post->ID, $key, $value);

        if(!$value) delete_post_meta($post->ID, $key); // Delete if blank
    }
}

add_action('save_post', 'save_nwt_home_section_settings_meta', 1, 2); // save the custom fields

Please try somthing like this

$resources = $_POST['authors-commentary-resources'];
    $sanitized_resources = array();
    foreach ( $resources as $resource ) {

        $resource = esc_url( strip_tags( $resource ) );
        if ( ! empty( $resource ) ) {
            $sanitized_resources[] = $resource;
        }

    }

    update_post_meta( $post_id, 'authors-commentary-resources', $sanitized_resources );

}
