Looking for useful code snippets for WordPress?

You can expand the functionality of your WordPress site by adding custom code to your theme. Code snippets for WordPress are used to do certain actions that might otherwise require a dedicated smaller plugin.

Please note that adding code functions incorrectly to your functions.php file could break your website. If you are not experienced in coding you should use a plugin like Code Snippets.


WordPress Snippets

Remove Admin Bar For Subscribers

For those of you who have subscribers on your WordPress website and don’t want them to see the admin bar when they are logged in, add this code to your functions.php file or functionality plugin:

add_action('set_current_user', 'ed_hide_admin_bar');
function ed_hide_admin_bar() {
  if (!current_user_can('edit_posts')) {


To add a shortcode from within a template instead of with the content of a Post/Page, you can add the following in your template:

<?php echo do_shortcode("[add-your-shortcode-here]"); ?>

[Year] Shortcode

Create your own shortcode! If you want to add an automatic year entry into your theme, like you would in your footer for current year, add the following:

function year_shortcode() {
  $year = date('Y');
  return $year;
add_shortcode('year', 'year_shortcode');

Turn on WordPress Error Reporting

For local development and testing you can add the following to your wp-config.php file to get more detailed error reporting from your WordPress site.

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);

Increase Memory Limit

Is your website taking a long time to load? Do you have lots of plugins or a lot of traffic? For this reason you can increase your memory limit  by adding the following to your wp-config file:

define('WP_MEMORY_LIMIT', '256M');


Add the following code to your .htaccess file to force your website to load on https and not http:

RewriteEngine On 
RewriteCond %{HTTPS} off 
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Leverage Browser Caching

This is a great snippet for speeding up your website. Paste it into your .htaccess file:

ExpiresActive On ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"

Upload SVG files

There’s no SVG support in WordPress by default so if you need to upload an svg file add this code to your functions.php file or functionality plugin:

function add_file_types_to_uploads($file_types){
$new_filetypes = array();
$new_filetypes[‘svg’] = ‘image/svg+xml’;
$file_types = array_merge($file_types, $new_filetypes );
return $file_types;
add_filter(‘upload_mimes’, ‘add_file_types_to_uploads’);

  // Return the number of products you wanna show per page.
  $cols = 9;
  return $cols;
