Stuck on Wordpress Plugin Challenge - Custom_Filter

Write an empty function named custom_filter(). Then add your function to the "the_content" filter.

<?php

function custom_filter( $content ) { return $content; }

add_filter(‘the_content’,'custom_filter’); ?>

Hi Jesse Janson

It's asking you to write an empty function which means the function isn't doing anything. Read your function and ask yourself, what is this function doing?

Having same problem too... says Bummer! The wrong custom filter was passed to add_filter(). It should be named "custom_filter".

            <?php 
function custom_filter(){}
add_filter("the_content");

?> ```
