我通过以下代码使其工作：

add_action( \'template_redirect\', \'ft_job_cpt_template\' );

function ft_job_cpt_template() {
    global $wp, $wp_query;

    if ( isset( $wp->query_vars[\'post_type\'] ) && $wp->query_vars[\'post_type\'] == \'job\' ) {
        if ( have_posts() ) {
            add_filter( \'the_content\', \'ft_job_cpt_template_filter\' );
        }
        else {
            $wp_query->is_404 = true;
        }
    }
}

function ft_job_cpt_template_filter( $content ) {

    global $wp_query;
    $jobID = $wp_query->post->ID;

    $output = \'\'; // Build markup fetching info from postmeta

    return $output;
}
