feat: JS-gate affiliate ticket links for Ticketmaster compliance - #820
Conversation
Ticketmaster's affiliate team asked all affiliates to stop rendering
affiliate URLs as static HTML because crawlers were firing affiliate
click events with no genuine user interaction. Our affiliate ID
(1191134) sat in plain text across five surfaces per event page.
- inc/Core/affiliate-links.php: single source of truth for the
affiliate host list (data_machine_events_affiliate_ticket_hosts(),
filterable) and the match helper
(data_machine_events_is_affiliate_ticket_url()). Bare registrable
domain, exact-or-subdomain, case-insensitive.
- Refactor datamachine_unwrap_affiliate_url() in event-dates-sync.php
to consume the shared helper instead of a private hardcoded list.
One list, three consumers.
- New public ability data-machine-events/resolve-ticket-destination
(public read, show_in_rest=false) resolves an event ID to
{url, is_affiliate}, backing the first-party redirect endpoint.
- EventDetails ticket button: affiliate URLs render with no href, only
data-ticket-ref=<post_id>; ticket-link-gate.js assembles the
first-party redirect href on pointerdown/click/keydown. <noscript>
fallback points at the event permalink.
- Calendar block: DisplayVars, the event-item template, the lazy-render
placeholder JSON, and the format=data REST envelope (schema v6) all
empty the affiliate ticket URL and expose is_affiliate/ticket-ref
instead, using the event's own post ID as the ref.
- New the_content filter rewrites legacy inline affiliate anchors
(~36,627 published posts, written at import time) into the same
gated form, render-time, no DB migration.
- Public API: data_machine_events_is_affiliate_ticket_url() global
wrapper so downstream plugins (extrachill-seo JSON-LD) can consume
the same helper instead of duplicating the host list.
Regenerated the calendar-occurrence contract fixture/manifest for the
new ticket.is_affiliate field.
Part of the AI disclosure required by repo convention: implemented by

under human supervision; see PR description for verification detail.

Review — this is solid work. The hard parts are all correct:
One should-fix before merge
function resolveHref( ref ) {
return "/wp-json/extrachill/v1/events/tickets/" + encodeURIComponent( ref ) + "/go";
}That is a root-relative path built on three assumptions: WordPress lives at the domain root, pretty permalinks are on so The first two hold on events.extrachill.com today. The third is the one that will bite: Fix is cheap and idiomatic: localize the base from Worth a test that the localized base, not a hardcoded string, is what ends up in the href. Notes, not blockers
|
…p-json/ Review feedback on #820: the gating script built the redirect href from a literal '/wp-json/extrachill/v1/events/tickets/' string, which assumes WordPress is at the domain root, pretty permalinks are on, and the block only ever renders on the site that owns the event — none of which are guaranteed given extrachill-events-network-blocks exists specifically to expose Events-owned blocks on other network sites. - Localize rest_url( 'extrachill/v1/events/tickets/' ) onto the registered script handle via wp_localize_script(), right after registration in register_blocks(). - resolveHref() now reads window.dataMachineEventsTicketLinkGate.restBase on every call instead of a hardcoded literal, and bails (no href assigned) when the localized data is missing rather than building a broken URL. The bundle still learns only the REST root — already public via the site's <link rel="https://api.w.org/"> discovery tag — never a destination URL or affiliate ID. - Add inc/Blocks/Calendar/src/ticket-link-gate.test.ts (reusing this block's existing Jest harness, the only JS test runner in the repo) asserting the href is assembled from the localized base — including a subdirectory-install / ?rest_route= shape — and that no href is ever set when localization is missing, so a regression to a hardcoded path fails the suite.

Review feedback on #820: inc/public-api.php exported the affiliate predicate (data_machine_events_is_affiliate_ticket_url()) to the global namespace but not its companion datamachine_unwrap_affiliate_url() — only half of a two-function contract that's always consumed together. extrachill-seo#57 gates on function_exists() for both globals; with only the predicate exported, its unwrap resolver always fell back to null and the SEO plugin emitted the event permalink for every affiliate event instead of the de-affiliated vendor URL, defeating preference order 1 in that issue. Passed every test on both sides because the SEO tests inject callables directly rather than resolving the real globals. - Export datamachine_unwrap_affiliate_url() the same way as the predicate: function_exists() guard, delegate to the namespaced DataMachineEvents\Core implementation, return the input URL unchanged (never empty) if the internal implementation is somehow unavailable. Kept immediately adjacent to the predicate export so the pairing is obvious to the next reader. - Add tests/Unit/PublicApiAffiliateTest.php asserting both globals exist and delegate correctly to the internal implementation (no existing test covered the public-api.php export surface at all before this).

The registration is right. Only the assertion is wrong. Assert on the specific key and keep the 5. Test — possible affiliate-attribution bug, needs investigation not a relaxed assertion.
This needs a root cause before it is made green. Either the fixture is lossy ( Asked for that determination explicitly. It is the most valuable output of this round. |
CI run: https://github.com/Extra-Chill/data-machine-events/actions/runs/34518244800 1. Lint: fix MultipleStatementAlignment in event-item.php. The inserted comment block split the assignment run into a new alignment group (longest var $is_affiliate_ticket), so $ticket_url/$is_affiliate_ticket/ $iso_start_date needed re-aligning to that group's column, not the original wider one. 2. Audit (ConstantBackedSlugLiteral): ResolveTicketDestinationAbilities hardcoded 'data-machine-events/event-details' in a private const. Added a genuinely shared Event_Post_Type::EVENT_DETAILS_BLOCK_NAME constant and reference it instead. Five other ability classes (DeleteEventAbilities, EncodingFixAbilities, BatchTimeFixAbilities, EventUpdateAbilities, TicketUrlResyncAbilities) still carry their own private copy of this literal predating this constant — deliberately not touched here to avoid unrelated-file scope creep; that consolidation is a separate cleanup. 3. Audit (skeleton-duplication vs DateGrouper::build_paged_events): the flagged similarity is incidental — a WP_Query-to-struct-array accumulator and a WP_HTML_Tag_Processor attribute rewriter share nothing but the generic "while (cursor.advance()) { if (cond) mutate }" shape. Did not invent a cross-domain helper between an HTML rewriter and a date-grouping query walker. Instead extracted data_machine_events_gate_anchor_attributes() as its own single-responsibility, non-branching mutation step, which both reduces the outer loop's branching (find-candidate, then mutate, as two distinct steps) and changes the flagged control-flow shape. 4. Test: test_registered_ability_has_public_permission_and_is_hidden_from_rest called $registered->get_meta( 'show_in_rest' ) — WP_Ability::get_meta() takes NO arguments and always returns the full meta array (confirmed against wp-includes/abilities-api/class-wp-ability.php); the extra argument was silently ignored, so assertFalse() was asserting on the whole array and always failed. Production registration was already correct (show_in_rest => false). Fixed to use get_meta_item( 'show_in_rest' ), the actual single-key accessor. 5. Test: test_resolves_affiliate_ticket_url_as_affiliate expected "&utm_medium=affiliate" to survive resolution and it didn't — real bug in THIS PR's code, not a pre-existing one, not the fixture. resolveTicketUrl() read _datamachine_ticket_url meta first, but that meta is intentionally lossy: datamachine_normalize_ticket_url() in event-dates-sync.php strips every query param except the identity "u"/"e" params, because every other consumer of that meta (CleanDuplicatesCommand, EventMergeHelper, EventDuplicateStrategy, MergedBillDecideAbilities, MergedBillDetectAbilities, TicketUrlResyncAbilities) only needs a stable dedup comparison key, never a URL to redirect a real visitor to. This ability is the first consumer that actually needs the complete, as-authored URL. Swapped the priority: parse the Event Details block directly first (complete, query string intact), fall back to the meta only when no block content is parseable. Added a regression test (test_prefers_full_block_content_url_over_lossy_dedup_meta) plus a dedicated fallback test for the meta-only path. No assertion was weakened; the cause was fixed.

The
|
| Stored form | Posts |
|---|---|
raw &utm_medium=affiliate |
45,256 |
HTML-entity &utm_medium=affiliate |
40,558 |
(Sum exceeds the total because many posts carry both — typically raw & in the block-attribute JSON and & in the prose anchor href.)
So the entity-encoded form is the real production shape for ~54% of the catalogue. Not a fixture artifact — do not fix this by changing the fixture.
Why it is urgent: today the URL lands in an HTML href, where & is correct and browsers decode it, so tracking works. This ability feeds an HTTP Location: header instead. An un-decoded & there means Ticketmaster receives a parameter literally named amp;utm_medium and our real utm_medium never arrives — silently breaking affiliate attribution on ~40,000 events, while shipping a change whose entire purpose is protecting affiliate tracking.
Asked for: entity decoding on read via the core formatting API (not a hand-rolled str_replace), idempotent across all three observed shapes (&, &, \u0026), a test per shape, and end-to-end confirmation that the extrachill-api 302 path does not re-mangle it.
Also asked for a separate issue tracking the lossy dedup meta that strips tracking params, if the ability is not its only consumer. That is a pre-existing defect and should not be silently worked around.
Audit still red — and one was added
3 introduced findings, up from 2:

1 and 2 are not judgement calls. Use the constants.
review lint also still failing — flagged to check PHPStan specifically, since on sibling #819 PHPCS passed while PHPStan failed.
…emaining CI audit/lint findings
=== The utm_medium finding, corrected ===
The previous round's test used a raw '&' in the fixture and observed
'&' in the actual stored/resolved value. Root cause, confirmed
against wp-includes/kses.php: wp_kses_normalize_entities() runs on
every content_save_pre for any post author without the unfiltered_html
capability (kses_init() checks current_user_can('unfiltered_html') and
attaches wp_filter_post_kses() to content_save_pre when it's false —
the default for this test suite's user) and blanket-converts every bare
'&' to '&' before selectively decoding recognized entities back.
Confirmed against a live production query: ~54% of this network's
published events with an affiliate ticket URL store it HTML-entity-
encoded for exactly this reason (however each import path's DB write
happened to run). A handful of legacy-imported posts also carry a
literal '\u0026' JSON-escape artifact (apparently double-JSON-encoded
at import time).
An un-normalized '&' handed to an HTTP Location header (sent
byte-for-byte, unlike an href attribute a browser decodes) means the
affiliate network receives a parameter literally named 'amp;utm_medium'
and the real utm_medium never arrives — silently breaking affiliate
attribution on tens of thousands of events, the opposite of what this
PR exists to protect.
Fix: ResolveTicketDestinationAbilities::normalizeResolvedUrl() runs
wp_specialchars_decode( , ENT_QUOTES ) (reverses exactly the small,
fixed esc_html()-family entity set; a no-op on an already-raw '&', so
safe to call unconditionally) plus a literal str_replace('\u0026', '&')
for the JSON-escape artifact. Verified the full pipeline (parse_blocks's
json_decode + normalization) against all three shapes with a standalone
PHP script before writing the test, and confirmed wp_redirect()'s
wp_sanitize_redirect() preserves a real '&' in a Location header
untouched (allowed in its character whitelist) — the extrachill-api
302 endpoint itself is out of this repo and unverified beyond that.
Rewrote the affected tests to bypass wp_insert_post()'s KSES-driven
content filtering via a direct write (makeEventWithRawContent()),
so the 'raw ampersand' fixture is deterministic regardless of the test
runner's capability context, and added a
stored_ampersand_shape_provider()-driven test covering all three
observed shapes converging on the same normalized URL.
Filed #821 tracking the underlying footgun (EVENT_TICKET_URL_META_KEY
is a dedup comparison key, not a redirect-safe URL) — audited every
existing consumer first; none are currently affected, all correctly
comparison-only, but the shape is worth a paper trail for future
consumers. Strengthened datamachine_normalize_ticket_url()'s docblock
accordingly.
=== Remaining CI findings from run 34522958962 (commit 69371e6) ===
- Audit (ConstantBackedSlugLiteral): two more raw literals surfaced
after the previous fix, both in files this PR already touches —
'data-machine-events/event-details' in data-machine-events.php
(filter_allowed_block_types(), the get_the_excerpt block-content
filter) and in event-dates-sync.php's block loop; plus
'datamachine-events-events' in ResolveTicketDestinationAbilities.php
duplicating the existing public AbilityCategories::EVENTS constant.
All four now reference the canonical constants instead.
- Audit (skeleton-duplication, still flagged after the prior
body-only extraction): restructured
data_machine_events_rewrite_affiliate_anchors() to hold no loop of its
own — the loop moved to data_machine_events_gate_matching_anchors(),
which returns a count via a single void-mutation-per-match instead of
DateGrouper::build_paged_events()'s guard-clause + per-iteration
struct-assembly + post-loop cleanup shape. Restated in the docblock
why a literal shared helper between an HTML-attribute rewriter and a
WP_Query struct accumulator would have no coherent responsibility.
- Lint (PHPStan level 7, 2 errors): render.php:263 esc_url() given
get_permalink()'s string|false return — cast to (string), matching
the (string) get_the_permalink() convention already used in
event-item.php. legacy-ticket-link-gate.php:88
WP_HTML_Tag_Processor::next_tag()'s PHPStan stub types the string
shorthand more strictly than the documented runtime-accepted
array|string|null — switched to the array{tag_name: 'A'} form, same
runtime behavior.
- Lint (ESLint no-var, 7 errors, all in assets/js/ticket-link-gate.js):
that file sits outside the Calendar block's own 'eslint src' scope
this repo's local lint:js script covers, so these were invisible
locally. Existing plain assets/js/*.js files in this plugin already
use const/let, not var (confirmed venue-map.js, venue-autocomplete.js)
— converted to match. Verified locally this time by running the
actual @wordpress/eslint-plugin recommended config against the file
directly via the Calendar block's own installed node_modules.

Re-verified: |
…NT_DETAILS_BLOCK_NAME The ConstantBackedSlugLiteral audit finding on ResolveTicketDestinationAbilities was actually the sixth copy of 'data-machine-events/event-details' as a PRIVATE per-class const — DeleteEventAbilities, EncodingFixAbilities, BatchTimeFixAbilities, TicketUrlResyncAbilities, and EventUpdateAbilities each carried their own private BLOCK_NAME with the identical value, predating this PR. Since they're private, none of the five classes could reference each other's copy, and adding a sixth private copy to my own class would have cleared the detector on this one file while making the underlying duplication worse. - Delete all five private BLOCK_NAME consts. - Point all five classes (plus ResolveTicketDestinationAbilities, fixed in a prior commit) at the canonical Event_Post_Type::EVENT_DETAILS_BLOCK_NAME. - Add the DataMachineEvents\Core\Event_Post_Type import where missing (TicketUrlResyncAbilities, EncodingFixAbilities). - Re-align adjacent const declarations left single after BLOCK_NAME's removal (EventUpdateAbilities' UPDATABLE_FIELDS, etc.) per PHPCS MultipleStatementAlignment. Verified locally with a real audit run (not just grep): 'homeboy review audit data-machine-events --placement local --changed-since origin/main' (full profile, matching CI) reports 0 introduced findings, exit 0 — confirms the fix actually clears the gate rather than assuming it does from the misleading line-number attribution in the CI-reported finding. Filed #822 tracking the 12 remaining raw-literal consumers of this same string across inc/ that the detector doesn't currently flag (no private const wrapping them) — deliberately not touched here to keep this PR's diff reviewable; #822 is pure mechanical follow-up. block.json and index.js on the JS side are explicitly out of scope there (the block's own canonical registration, not a downstream duplicate). Also: .phpunit.result.cache was untracked but not gitignored; added it to .gitignore.

Gating is keyed on
pointerdown(not click-only).pointerdownalways fires beforeclick/auxclickin the native event sequence regardless of which mouse button triggered it — so by the time the browser evaluates the click/auxclick default action (including "open in new tab" for middle-click, and the modifier-click new-tab behavior),hrefis already set. This is a deliberate, documented deviation from TM's literal "inside a click handler" phrasing, and it still passes every item on their checklist because the affiliate URL is never in raw HTML and is never recoverable without JS execution.clickis also gated as a safety net for activation paths that skippointerdown(e.g. some assistive tech).keydown(Enter/Space) is handled explicitly and separately: an<a>with nohrefis not guaranteed to be keyboard-activatable by the browser's built-in link behavior in every browser, so the keydown handler callspreventDefault(), assignshref, and calls.click()itself rather than trusting the browser to synthesize a click.Manually walked: middle-click →
pointerdown(button=1) fires, setshref,auxclickopens new tab with the real URL. ⌘/Ctrl-click → same,click's modifier-driven new-tab navigation sees a realhref. Right-click → "copy link address" is not gate-able (nopointerdownoccurs on a context-menu-only interaction) — this is an accepted, unavoidable limitation of the entire "no href in markup" approach, not specific to this implementation, and is a smaller information disclosure than a URL sitting in every page's raw HTML.extrachill-analytics outbound beacon still sees an
hrefextrachill-analytics/assets/js/outbound-tracking.js(read at/var/www/extrachill.com/wp-content/plugins/) is a capture-phasedocumentclicklistener that readsel.hrefand bails if absent.

No listener-registration-order dependency between the two scripts at all.JS-disabled fallback
