php - 将自定义帖子类型“问题”的永久链接更改为帖子 ID

Question

我需要显示这样的问题，从 quizzes/quiz-1/question-1 到 quizzes/quiz-1/%question-post-id%/

我改变了 $permalink = $permalink 。$question_id; 但它不起作用。

任何帮助将不胜感激。我花了几天时间解决这个问题。

/**

* If permalink option is turn on, add name of question
* into quiz permalink. Otherwise, add it’s ID into
* query var.
*
* @param int $question_id
*
* @return string
*/
public function get_question_link( $question_id = null ) {
$course = LP_Global::course();
$permalink = $course->get_item_link( $this->get_id()   );
if ( ” != get_option( ‘permalink_structure’ ) && get_post_status( $this->get_id() ) != ‘draft’ ) {
if ( get_post_type( $question_id ) === LP_QUESTION_CPT ) {
$question_name = get_post_field( ‘post_name’,  $question_id );
$permalink = $permalink . $question_name;
}
} else {
$permalink = add_query_arg( array( ‘question’, $question_id ), $permalink );
}

// @deprecated
