Head & Footer Code Plugin

Easy add site-wide, category and article specific custom code before the closing </head> and </body>, or after opening <body> tag.

Head & Footer Code plugin helps you add custom code snippets (JavaScript, CSS, or HTML) to the page even if you are not a programmer. It could be within the <head> (site verification code for various services, custom styles, meta or Webfont link), right after opening <body> (pixel tracking, analytics or heatmap code) or just before closing </body> tag.

Go to Tools → Head & Footer Code in WordPress Dashboard. Insert custom code to HEAD, BODY or FOOTER section (depending on what you have to do).

All magic is done by hooking to WordPress hooks wp_head, wp_footer and wp_body_open.

Homepage in Blog Posts mode

If your WordPress shows the latest blog posts on the homepage, you can also add specific code only for the homepage on Tools → Head & Footer Code (there will be section Head, body and footer code on Homepage in Blog Posts mode)

Article specific code

To insert custom code specific for individual article (post, page or custom post type), use article-specific Metabox while editing post/page/custom post type (check out Screenshots). There choose if that specific code appends to site-wide code defined on Tools → Head & Footer Code, or to replace it.

Category specific code

You can also define a Category specific code on each individual category.

Other taxonomies (tag and custom taxonomy) do not have available their specific code, but for them a Global code is used instead.

FAQ

On Network WordPress an Administrator/Editor/Author user getting code validation hint error `Tag is not allowed.`

It’s not a bug, it’s a security measure by WordPress Core.

If you wish to remove hinting errors for Administrator role, make sure you allow unfiltered_html capability for that role (Google is your friend).

Is supported PHP code in code snippets?

As it’s a security risk, the Head & Footer Code does not process PHP code if entered into any plugin field (global or article specific).

Any content added to HFC fields is printed on the front-end as is.

I entered code to BODY section, but nothing outputs on front-end

This feature is implemented since WordPress version 5.2 and requires theme compatibility.

To make sure if theme you use supports wp_body_open hook, open in code editor header.php file from theme you use, and check if right after opening <BODY> tag there is following code (if it does not exists, add it or ask some developer to do that for you):

if ( function_exists( 'wp_body_open' ) ) { wp_body_open(); }

Where do I report security bugs found in this plugin?
