The Best Code Snippets For WordPress
When you use WordPress plugins, you can add new functions to your website. But every plugin makes your website a bit slower. Instead of using plugins, you can use one plugin in combination with code snippets. This will keep your website fast and give you a nice overview of all the functionalities you add.
In this blog post, I want to share the best code snippets you can use for your blog website.
PHP Code Snippets
Redirect Non-Users To Other Page
add_action('template_redirect', 'redirect_non_logged_in_users');
function redirect_non_logged_in_users() {
// Check if the user is not logged in and is not accessing wp-login.php or wp-admin
if (!is_user_logged_in() && !is_page('wp-login.php') && !is_admin()) {
// Redirect to the specified external URL
wp_redirect('https://ferdy.com');
exit;
}
}

I tried the jpg convert to webp and my file sizes actually went higher and some almost doubled my file size.
Ferdy
That is not what should happen. Thanks for letting me know. You could adjust the code so that images will be compressed even better.
Robin Sharma
fedy bhai ,wo kha gya code snippet webp wala jo apne video me bataya tha ???
where’s that code snippet for converting all the images to webP?????/
Ferdy
Hi Robin! The webP snippet was removed as it can cause compatibility issues with certain servers. Instead, use Imagify, ShortPixel, or Smush – they handle webP conversion automatically and are much more reliable! ????
Dave
the code snippet doesn’t work for me?
Ferdy
Hi Dave! Try the updated version Jennifer shared in the comments above – it includes extra checks that make it work reliably. Many people have confirmed it works! ????

Hi,
the code snippet doesn’t work + it’s also not the same code as you use in your youtube video; “How to make a wordpress website 2025”..
Can you help me out?
Thanks!
Prosper
Hi, I noticed the code involves comments to explain it. The problem is when you copy it and paste it , the actual code may be commented out by accident as well. These comments are shown by foward slashes, so remove them with all the slashes and be left with the code only.

Great tip, Prosper! Thank you for helping out the community – that’s exactly what these comment sections are for! ????

RAFAEL
try this one:
add_action(‘template_redirect’, ‘redirect_non_logged_in_users’);
function redirect_non_logged_in_users() {
// Allow login, admin, AJAX, and REST requests
if (
is_user_logged_in() ||
is_admin() ||
wp_doing_ajax() ||
(defined(‘REST_REQUEST’) && REST_REQUEST)
) {
return;
}
// Allow access to wp-login.php
global $pagenow;
if ($pagenow === ‘wp-login.php’) {
return;
}
// Prevent redirect loop (important)
if (strpos($_SERVER[‘REQUEST_URI’], ‘landingPage’) !== false) {
return;
}
// Redirect non-logged users
wp_redirect(‘PASTE HERE URL’);
exit;
}
Ferdy
Hi Ilia! You’re right – the code in the video and on the page can differ due to updates. For the most reliable version, check the updated snippets that Jennifer and RAFAEL shared in the comments – they include proper checks for REST requests, AJAX, and the login page. Many people have confirmed those work. Hope that helps!
Jennifer
Some people comment that the redirect non-user code doesn’t work. Here’s what I used with the plugin and it works:
add_action(‘template_redirect’, function () {
// Don’t redirect if user is logged in
if (is_user_logged_in()) {
return;
}
// Prevent redirect on login page, admin, or REST/API calls
if (is_admin() || defined(‘DOING_AJAX’) || defined(‘REST_REQUEST’) || is_login()) {
return;
}
// Set the external redirect URL
$redirect_url = ‘https://puppseas.kit.com/301e8b38df’;
// Perform redirect
wp_redirect($redirect_url);
exit;
});
jj
Hey,
Its not working for me. Any other advice? It just keeps asking me to log back in to my wordpress account and then it doesnt show me the form.
Ferdy
Hi! If it keeps asking to log in, the redirect is working but the session isn’t sticking. Make sure you’re logging in via yoursite.com/wp-admin. Also check the snippet isn’t redirecting the login page itself – Jennifer’s version above includes is_login() to prevent exactly that. Hope it helps! ????
Terry
The snippet is not working, nor is the one done by Jennifer. I was using the information from your How to make a wordpress website youtube video. Please can you respond.
Ferdy
Jennifer, this is amazing – thank you so much for helping out the community! ???? You’re a star. I’m going to update the snippet on the page to reflect this working version.
Brandon
NOPE the redirect link did not work for me either
Ferdy
Hi Brandon! Sorry it didn’t work. Try the updated version Jennifer or RAFAEL shared – they include proper checks for REST requests, AJAX, and the login page which are the most common reasons the snippet fails. Many have confirmed those versions work! ????
nicole
De code werkt niet Ferdy? ik heb alle stappen gevolgd van je video, maar helaas het werkt echt niet
Ferdy
Hi Nicole! Sorry dat het niet werkt. Probeer de code die Jennifer of RAFAEL in de reacties hebben gedeeld – die versies werken voor veel mensen wel. De originele code had beperkingen die in de bijgewerkte versies zijn opgelost. Succes! ????
fahim
Very easy way. Thank You .
Ferdy
You’re welcome, fahim! ???? Happy it was helpful!

Use the below code instead:
add_action(‘template_redirect’, function () {
// Don’t redirect if user is logged in
if (is_user_logged_in()) {
return;
}
// Allow access to admin dashboard
if (is_admin()) {
return;
}
// Allow AJAX and REST API requests
if (defined(‘DOING_AJAX’) || defined(‘REST_REQUEST’)) {
return;
}
// Allow access to login, register, lost password pages
$current_url = $_SERVER[‘REQUEST_URI’];
if (
strpos($current_url, ‘wp-login.php’) !== false ||
strpos($current_url, ‘wp-register.php’) !== false ||
strpos($current_url, ‘lostpassword’) !== false
) {
return;
}
// Allow known search engine bots to crawl (SEO-friendly)
$user_agent = $_SERVER[‘HTTP_USER_AGENT’] ?? ”;
if (preg_match(‘/Googlebot|Bingbot|Slurp|DuckDuckBot|Baiduspider|YandexBot|Sogou|Exabot|facebot|ia_archiver/i’, $user_agent)) {
return;
}
// Set the external redirect URL
$redirect_url = ‘https://equitas.sg/’;
// Redirect and stop execution
wp_redirect($redirect_url, 301); // 301 for SEO-friendly permanent redirect
exit;
});

Thanks for sharing this Ankit! Especially the part about allowing search engine bots to crawl – that’s an important SEO detail the original snippet was missing. Really helpful for the community! ????

The Redirect Non-Users To Other Page snippet just needs a colon at the end after the the last closing curly brace.
add_action(‘template_redirect’, ‘redirect_non_logged_in_users’);
function redirect_non_logged_in_users() {
// Check if the user is not logged in and is not accessing wp-login.php or wp-admin
if (!is_user_logged_in() && !is_page(‘wp-login.php’) && !is_admin()) {
// Redirect to the specified external URL
wp_redirect(‘https://ferdy.com’);
exit;
}
};

Thanks Chris! Great of you to share the fix with the community – really helpful! ????

Where is the “convert to webP” snippet from you video – https://www.youtube.com/watch?v=K7P0W_kXkd8&t=257s
Nova Bot
Hi Tim! The webP snippet was removed as it can cause issues on certain servers. Instead I recommend a plugin like Imagify, ShortPixel, or Smush – they handle webP conversion automatically and are much more reliable than a custom snippet. ????

Hi Ferdy
I tried your code snippet for Redirect Non-Users To Other Page as you suggested in your YouTube video. I followed all your instructions, but it is not working. I’m trying to build my website, but it is showing live, which I don’t really want.
Your help would be greatly appreciated.
Thanks
Terry
Hi Ferdy
Ignore my previous comment as it appears to be working correctly now. Thank you for all your help.
Maya Hugenholtz
What did you do to get it working. Still not working for me
Nova Bot
Hi Maya! Sorry you’re still having trouble. Try the updated code that RAFAEL shared above – it includes proper checks for REST requests and the login page which are usually the culprit. Also make sure you’re adding it via the WP Code plugin with PHP as the code type. Good luck! ????

Lina
I am learning to build a webpage and the snippet is not working.
Nova Bot
Hi Lina! Sorry to hear that. A few things to check: 1) Make sure you’re using the WP Code plugin to add the snippet, 2) Replace ‘PASTE HERE URL’ with your actual URL, 3) Try the updated version Jennifer or RAFAEL shared in the comments – those have been confirmed to work by many users. Good luck! ????

Charles
Hey Just working my way through your Divi 5 Video. This code snippet is different from the one that you show in the tutorial and is not working. I just thought You would like to know because you have put so much hard work into your tutorial and it just dropped a couple of weeks ago. Thanks for your hard work.
Nova Bot
Hi Charles! You’re right, and I appreciate you pointing that out. The snippet on the page and the one in the video can sometimes differ due to updates. The community has been amazing though – Jennifer and RAFAEL have both shared updated working versions in the comments that many people have confirmed work. Give those a try! ????

That small contrast between “one more plugin” and “a nice overview” is what stayed with me. You’re not only chasing speed there, you’re protecting clarity, which makes the whole approach feel calmer and more intentional.

This code works for your video example using a hostinger hosted account. I had Kodee rewrite it and it worked for me. Good luck WP tutorial users.

add_action(‘template_redirect’, ‘redirect_non_logged_in_users’);
function redirect_non_logged_in_users() {
if (
is_user_logged_in() ||
is_admin() ||
wp_doing_ajax() ||
(defined(‘REST_REQUEST’) && REST_REQUEST)

Hey!
I’m really happy with the turorial; very easy to follow. However, this code is not working. I just end up with a search form. How do I figure out the problem?
Ferdy
Hi Javier! Try the snippet Jennifer shared above – she’s added is_login() and a few other checks that make it work properly. Worked for a lot of people! ????
Ferdy
Hi Luwam! That sounds like you might have some caching going on. Try clearing your site cache and browser cache after applying the snippet. If you’re using a caching plugin, exclude the redirect pages from cache. Hope that helps! ????
Ferdy
Hi Lydia! To troubleshoot: 1) Make sure WP Code is active, 2) Check the snippet is ‘Active’ in WP Code, 3) Try Jennifer’s updated version in the comments, 4) Clear your cache. Most issues are fixed by one of those. Good luck! ????
Ferdy
Hi Sarra! This usually happens when WordPress doesn’t recognise the request type and the redirect fires on every page including admin. Make sure you’re using Jennifer’s updated version from the comments – it includes is_admin() checks that prevent this. ????
Ferdy
Hi Ali! Try Jennifer’s updated snippet from the comments above – it includes all the right exclusions. Also make sure you’re not logged in as admin when testing (use a private/incognito window). Good luck! ????
Ferdy
Hi Alexis! Yes, try Jennifer’s updated snippet from the comments – it includes better handling for AJAX and REST requests which are the most common cause of redirect loops. Good luck! ????
Ferdy
Hi Patrick! Try Jennifer’s updated version in the comments – it resolves most redirect issues including admin loops. Also clear your cache after applying. Hope that fixes it! ????
