SNIPPETS – Practical Solutions for WordPress & WooCommerce

Introduction

When working with WordPress, the same needs appear over and over again: small behavior changes, custom conditions, text adjustments, checkout logic, pricing tweaks, or features that core WordPress or plugins simply don’t offer.

That’s exactly where snippets come in.

This section is built as a practical library of proven solutions – small pieces of code designed to solve one specific problem efficiently, cleanly, and without writing a full plugin.

What is a snippet?

A snippet is a small piece of code (usually PHP, CSS, or JavaScript) that:

  • extends WordPress functionality,
  • modifies WooCommerce behavior,
  • adjusts frontend or backend output,
  • or hooks into WordPress actions and filters.

A properly written snippet is not a hack.
It follows WordPress standards and behaves the same way as code inside a plugin.

What are snippets used for?

Common use cases include:

  • changing button labels or system messages
  • conditional checkout or cart logic
  • automatic coupon generation
  • pricing, tax, or shipping adjustments
  • custom fields and metadata
  • WooCommerce email customization
  • conditional display of elements
  • performance or security optimizations

Snippets are powerful because they solve exactly one problem, nothing more.

Where and how are snippets added?

Quick but risky:

  • lost when switching themes
  • errors can break the entire site
  • poor maintainability

Useful for testing, not ideal long-term.

2. Custom mini-plugin (cleanest approach)

Snippets live inside a plugin:

  • theme-independent
  • better structure
  • scalable

Best practice, but sometimes overkill for small tweaks.

3. Snippet manager plugins (best balance)

Snippet plugins allow you to manage custom code safely from the admin panel:

  • enable / disable snippets instantly
  • prevent fatal errors
  • keep everything organized
  • no direct file editing

Popular solutions include:

Using these tools significantly reduces risk and speeds up development.

What to expect in this section?

Snippets published on makemehappy.sk are:

  • focused on real-world problems
  • tested in production projects
  • written clearly and extensibly
  • often commented and explained

Some are simple, others more advanced – but always practical.

Who is this for?

  • WordPress administrators
  • WooCommerce store owners
  • developers and freelancers
  • technical users who want control

If you understand hooks, filters, or at least functions.php, you’ll feel at home here.

Final thoughts

Snippets are one of the most efficient ways to shape WordPress exactly to your needs – without bloated plugins, without compromises, and without messy codebases.
