Can I return and include file in a function for creating shortcode?

1 Views

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>";
}

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.

I hoped something like this would work: 

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

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

  1. 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 '';
}

  2. Try below code :

    add_shortcode( 'about_us', 'shortcode_about' );

function shortcode_about()
{
   ob_start();
    require_once('about-us.php');
    $data = ob_get_contents();
   ob_end_clean();
   return $data;
}

    code in about-us.php 

    <div>Some content here.</div>

  3. Use this

    add_shortcode( 'about_us', 'shortcode_about' );
function add_shortcode()
{

    ob_start();
        include( dirname ( __FILE__ ) . '/include.php' );
    return ob_get_clean();
}

    and in include.php

    <h1>Test Content</h1>
<p>This is the data</p>
