Using code snippets

Before you install

Every entry states the plugin it targets, the kind of code it contains and its review status. Snippets are examples, not drop-in guarantees: test them on a staging site and keep a backup before changing a production site.

Review each page’s requirements before use. A Needs review label means copy or download controls are intentionally unavailable while a known issue remains unresolved.

Installable mini-plugins

Entries labeled Plugin include a WordPress plugin header. Download the ZIP when available, then use Plugins → Add New → Upload Plugin in WordPress. Activate it like any other plugin.

If only the PHP source is available, create a folder named after the plugin slug, save the PHP file inside it, compress the folder and upload that ZIP. Keep the filename unchanged.

Function snippets

Entries labeled Function snippet register hooks or define helper functions. Install them in one of these places:

• A small custom functionality plugin.
• A child theme’s functions.php file when the customization is theme-specific.
• An MU plugin when it should always run.

Check whether the example outputs markup immediately. Code that echoes markup usually belongs in a template or a hooked callback, not at the top level of functions.php.

Template examples

Entries labeled Template example are reference implementations for theme templates. Copy the relevant query, markup or callback into the correct template context. Do not upload the file to wp-content/plugins unless its page explicitly calls it an installable plugin.

After installation

If a snippet changes indexed content, search behavior or related-post matching, run any required plugin reindex or clear the plugin’s cache. Visit several affected posts and compare output before and after activation.

Requirements

Review each page’s plugin, Pro and PHP requirements before use. A Pro-only snippet needs the corresponding Pro plugin active. The companion page links to the relevant developer documentation where available.
