    add_meta_box(
        'apt_college_fields',
        __('College Fields'),
        'apt_college_fields_callback',
        'college',
        'normal',
        'default'
    );
}

add_action('add_meta_boxes','apt_add_fields_metabox');

//Display Fields Metabox Content

function apt_college_fields_callback($post)
{
    wp_nonce_field(basename(__FILE__),'wp_college_nonce');

Answer 1

您的代码块出错。您错过了$ _REQUEST [＆＃39; issue_check＆＃39;]

update_post_meta($post_id,'issue_check',sanitize_text_field(['issue_check']));

更正代码

update_post_meta($post_id,'issue_check',sanitize_text_field($_REQUEST['issue_check']));

Wordpress Post没有在编辑器中更新
