Step 3 of 4 in this challenge asks us to "wrap" the require statement in output buffering functions: "After the extract, require front-end.php in the inc folder. Before the require statement, start output buffering. Then, after the require statement, end the buffer."
I do this, but get an error, every time:
<?php
function my_plugin_shortcode( $atts, $content = null) {
global $post;
extract( shortcode_atts( array('num_courses' => '4'), $atts) );
ob_start();
require('inc/front-end.php');
ob_end_clean();
}
?>

17,730 PointsIt's not exactly worded well. As you technically did end the buffer. However according to the video right before at about the 6:30 mark, Zac describes that what you want to do here when creating the shortcode is end the buffer and returned the buffer content.
Knowing that we want to return $content we can use ob_get_clean() like so
ob_start();
require('inc/front-end.php');
$content= ob_get_clean();
hope that helps

This one worked for me

Courses Plus Student 34,936 PointsThanks. Yes, it's not worded that way at all--"end" the buffer, versus get the buffer results at the end (two different things). Ah well.
