我可以在用于创建短代码的函数中返回并包含文件吗? [英] Can I return and include file in a function for creating shortcode?

问题描述

我正在创建一个将返回一堆 HTML 元素的短代码.一开始这样做很好:

I am creating a shortcode that will return an bunch of HTML elements. In the beginning it was fine to do it this way:

add_shortcode( 'about_us', 'shortcode_about' );
function shortcode_about() {
    return "<div>Some content here.</div>";
}

但是现在我必须添加很多内容，我认为这些内容看起来不太好，因为我的functions.php 将充满很多这样的内容.我想知道我是否可以将它放在一个外部文件中并包含它.

But now I have to add a lot of content, which I think wouldn't look good as my functions.php will be filled with a lot of this. I was wondering if I can just put it in an external file and include it.

我希望这样的事情会奏效:

I hoped something like this would work:

add_shortcode( 'about_us', 'shortcode_about' );
function shortcode_about() {
    return include 'about-us.php';
}

当然，它没有.关于如何正确执行此操作的任何想法?谢谢

But of course, it didn't. Any ideas on how to do this properly? Thanks

推荐答案

add_shortcode( 'about_us', 'shortcode_about' );

function shortcode_about()
{
    // Get absolute path to file.
    $file = locate_template('my-file.php');

    // Check if file is found.
    if ($file) {
        // Return file contents.
        ob_start();
        include $file;
        return ob_get_clean();
    }

    return '';
}
