How to use AFFINGER5 custom fields for cleaner affiliate disclosures

Affiliate links are a useful way to support a blog, but disclosure text can quickly make a product review feel crowded. Repeating the same notice below every heading, inside every comparison box, or immediately before each link interrupts the reading flow, especially on mobile screens.

AFFINGER5 custom fields offer a practical way to separate disclosure content from the main article copy. You can save a reusable notice once, display it in a consistent location, and keep the visible wording short while still making the commercial relationship clear to Australian readers.

Why custom fields suit affiliate notices

A custom field stores a small piece of information alongside a WordPress post. Instead of typing the same disclosure manually into the editor, you can create a field such as affiliate_disclosure and place the required wording in its value. A template, shortcode, or suitable theme function can then display that value where you choose.

This approach is particularly useful for a blog covering hosting, WordPress plugins, travel products, and online courses. A review about a Sydney web-hosting provider may need a different note from an Okinawa hotel guide, while the layout can remain identical. The content changes without forcing you to edit the surrounding paragraphs.

AFFINGER5 is designed for bloggers who want control over article presentation, advertising areas, and conversion-focused layouts. If you are still deciding whether its options justify the learning curve, this AFFINGER5 theme review gives useful context about the move from a free theme.

Prepare the field before editing posts

First, enable Custom Fields in the WordPress editor if the panel is hidden. In the block editor, open the three-dot options menu, select Preferences, and look for the Panels area. In the classic editor, open Screen Options and tick Custom Fields. The exact wording can vary slightly with WordPress and AFFINGER5 settings.

Create a consistent field name rather than inventing a new one for every post. A simple key such as affiliate_disclosure is easier to reference in a template. Use a complete sentence as the value, for example: “This post contains affiliate links. If you buy through a link, I may earn a commission at no extra cost to you.”

Keep the key and wording consistent across the site. Changing affiliate_disclosure to affiliate_notice halfway through a content migration can leave older articles without a visible notice. A spreadsheet containing the field name, approved wording, and affected post categories can help when managing a large Australian blog.

Useful field settings

• Field name: affiliate_disclosure
• Value: a plain-text or short HTML disclosure
• Location: above the article, below the introduction, or near the first affiliate link
• Fallback: a general notice for posts where the field is empty

Choose a visible position

A disclosure should be easy to notice before a reader makes a purchase decision. A small notice directly below the title or featured image usually works well for product reviews. It remains separate from the opening paragraph, so the article can begin with an honest assessment rather than a legal-sounding interruption.

For longer tutorials, place the notice below the opening section and before the first recommendation. This is useful when a reader arrives through Google on a specific section rather than reading from the top. Someone comparing WordPress themes in Melbourne should not have to scroll through several screens before finding out that the article includes paid links.

AFFINGER5 lets you style the notice so it looks distinct without becoming visually aggressive. A pale background, modest border, smaller text, and comfortable padding can create separation. Avoid making the disclosure the same colour as a muted footnote, because accessibility and visibility matter more than saving a few pixels.

The location should also work on smartphones. Australian visitors often browse during a commute in Sydney, Brisbane, or Perth, where a narrow screen makes repeated inline notices especially distracting. Test the field output at common mobile widths and check that the text does not overlap buttons or affiliate banners.

Display the value safely in AFFINGER5

The custom field itself does not automatically appear in an article merely because it has been saved. It must be connected to a display method. Depending on your AFFINGER5 setup, this may be a theme-supported insertion area, a shortcode, a child-theme template, or a small PHP function.

A developer can retrieve the value with WordPress functions such as get_post_meta() and print it in the desired template location. The output should be escaped appropriately, usually with esc_html() for plain text or a carefully controlled HTML approach when links and formatting are required. Do not paste untested PHP into the main theme files, because a theme update can remove the change and a syntax error can take the site offline.

If you prefer not to edit PHP, use a reusable block or shortcode that reads the field value through a trusted plugin or custom functionality. The important principle is to keep the disclosure data in the post field while keeping its layout rules in one place. That makes a site-wide design change much easier.

Before publishing, test three cases: a post with the field filled, a post with the field empty, and an older post using a different template. The empty case should not create a blank bordered box, stray spacing, or an error message.

Write an Australian-compliant disclosure

Australian readers should be able to understand that a commercial relationship exists without interpreting vague language. Phrases such as “supported by readers” or “some links may help fund the site” can be too indirect when a commission is involved. State the relationship plainly and use familiar wording.

The Australian Competition and Consumer Commission expects advertising and commercial content to be presented honestly, while the AANA Code of Ethics also emphasises that advertising should be distinguishable from editorial content. A disclosure is not a substitute for accurate product claims, and it should not imply that every recommended service has been independently tested if that is not true.

A practical notice might read: “Disclosure: This article contains affiliate links. I may receive a commission if you purchase through them, at no additional cost to you.” If you receive products, discounts, or other benefits, adjust the wording to reflect that relationship. For financial products, health services, or regulated offers, obtain specialist advice rather than relying on a general blog notice.

Keep the notice clear

• Say that affiliate links or advertising are present
• Explain that a commission may be received
• State whether the reader pays an extra cost
• Place the notice before the first relevant recommendation
• Use the same plain meaning across desktop and mobile layouts

Match fields to different content types

One universal field is enough for many small blogs, but multiple fields can help as the site grows. You might use affiliate_disclosure for standard commission links, sponsored_disclosure for paid content, and product_received for items supplied for review. Each field should have a distinct purpose and approved wording.

Category-specific values are useful on a mixed personal blog. A Malta accommodation article may mention that a booking link can generate a commission, while a WordPress hosting tutorial may need to identify a referral relationship. Travel readers comparing hotels near Perth or flights from Adelaide deserve context that matches the recommendation they are considering.

Do not create so many fields that editing becomes confusing. A field should exist because its information, placement, or wording differs. If every post contains the same sentence, a default template notice may be more efficient, with a custom field used only when an article needs an exception.

A useful workflow is to create the field while drafting, review the rendered notice in preview, and then check the final page in a private browser window. Cached pages can show an older version, so clear the relevant cache before assuming that a field has failed.

Maintain trust as the site changes

Affiliate disclosure is part of content maintenance, not a one-time formatting task. Review older posts when an affiliate programme changes its terms, when a product link is replaced, or when AFFINGER5 receives a major update. A broken field output can make a compliant notice disappear from hundreds of pages.

Keep a record of where affiliate links appear and whether the notice is global or post-specific. WordPress search, a spreadsheet, or a content audit plugin can identify articles that contain referral URLs but lack the expected field. This is especially valuable after migrating from another theme or importing posts from a different site.

The disclosure should never be used to disguise weak recommendations. Explain who the product suits, identify meaningful limitations, and separate first-hand experience from general information. A former physical therapist writing about ergonomic equipment, for example, should distinguish personal use from clinical advice and avoid allowing commission potential to shape safety claims.

When custom fields, clear wording, and honest reviews work together, the disclosure becomes part of a dependable publishing system. Readers can recognise the commercial context quickly, while the article remains readable, calm, and useful on both a desktop in Canberra and a phone used anywhere across Australia.
