我已經創建了一個名爲「產品」和自定義分類名爲「PRODUCT_CATEGORY」爲了這個自定義後類型我還創建了一個CPT-模板文件「單一產品自定義文章類型。 PHP「用於顯示個人帖子和Taxonomy-Template」taxonomy-product_category「，用於顯示我的特定分類標準的所有帖子。自定義類型後單頁wp_query將無法正常工作
我使用the_permalink（）來獲取個別職位的URL，當你點擊後，你直接跳到「單product.php」 -page。我設法讓這一切工作，尋找CPT-模板單頁的單篇文章，但由於某種原因，我的wp_query將不會從「單product.php」 -page運行。它會抓住的唯一東西是帖子的標題，編輯器和縮略圖圖像內容，不會顯示其他自定義字段。我在我的CPT中創建了一些帶有一些自定義字段的metabox。這些領域的工作和顯示，他們應該從分類 - 歸檔頁面，但不是從單頁面，我不明白爲什麼？
這是我的代碼。我很欣賞在這方面得到一些幫助。提前致謝。
