Do you want to display code snippet in posts without a plugin? If you run a blog that focuses on programming, you probably want to to do that. Here’s how to do it.


First off, add this code to your theme’s functions.php file or in a site-specific plugin:

function bbcode( $attr, $content = null ) {
        $content = clean_pre($content); // Clean pre-tags
        return '<pre"><code>' .
                str_replace('<', '<', $content) . // Escape < chars
add_shortcode('code', 'bbcode');

Then, in your post, you can use the shortcode [code] to remove WordPress auto-formatting.

[ code]<?php echo 'Hello World!' ?>[/ code]

Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.
