可以创建一个生成输出的函数，然后使用Shortcode API:

/**
 * Returns --> Contact  |  Terms of Service  |  Privacy Policy  |  Careers
 *
 * @parm array $atts 
 * @return string 
 */
function wpse241695_arrow_contact_terms_of_service_privacy_policy_careers( $atts ) {
    return \'--> Contact  |  Terms of Service  | \' .
           \' Privacy Policy  |  Careers\';
}

// Wire up a handy shortcode to output the string.
// Usage: [arrow_contact_terms_of_service_privacy_policy_careers]
add_shortcode( \'arrow_contact_terms_of_service_privacy_policy_careers\', 
\'wpse241695_arrow_contact_terms_of_service_privacy_policy_careers\' );
