Question

您好我正在尝试锻炼如何在插件上使用短代码，但我坚持使用它..它是我在http://www.wpbeginner.com/wp-tutorials/how-to-add-rotating-testimonials-in-wordpress/上找到的插件

它工作正常，但没有正确输出代码，也不确定为什么会发生这种情况。

我已经升级了代码并删除了css和jquery代码，因为我将添加这些单独的文件..

任何帮助都会很棒！

Answer 1

如果查看Shortcode API“短代码处理程序......它们接受参数（属性）并返回结果（短代码输出）。”在你的函数中wpb_display_testimonials()你要返回的所有内容都应该在$return_string的值内.. echo语句和内联JS不能像你拥有它那样使用。

所以而不是

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

你想做更像的事情：

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

你也可以使用输出缓冲，虽然你已经在组装$return_string并且最好使用它然后你可以稍后重构。
