與輸出WordPress的簡碼的問題

Question

你好我想鍛鍊如何使用簡碼上的插件，但我堅持這個..它是一種插件，我就http://www.wpbeginner.com/wp-tutorials/how-to-add-rotating-testimonials-in-wordpress/

它正在一點點，但不輸出代碼中發現正確和不確定爲什麼會發生這種情況。

我已經升級了代碼，並刪除了CSS和jQuery代碼，我會添加這個單獨的文件..

任何幫助將是巨大的！

Answer 1

如果你看一下Shortcode API「簡碼處理......他們接受參數（屬性），並返回結果（簡碼輸出）。」在你的函數中wpb_display_testimonials()你想要返回的一切應該在$return_string的值內。echo語句和內聯JS不能像你那樣使用。

所以不是

?> <div> misc html </div> <? 

你想要做更多的東西一樣的：

$return_string += '<div> misc html </div>'; 

你也可以使用輸出緩衝雖然給了你已經組裝$return_string最好使用並獲得它的工作那麼你可以稍後重構。
