常见问题:
Where does the QR generator page appear?
By default at /qr-generator. You can change this in Settings → Intown QR Studio.
Does this plugin create any database tables?
No. The plugin is fully stateless — no tables, no stored files, no cleanup needed.
Does it work with caching plugins?
Yes. The generator page automatically signals caching plugins to exclude it. See the settings page for manual exclusion instructions if needed.
Does it work on multisite?
Yes. Supports both network activation and per-site activation with independent settings per site.
Can I embed the QR generator on an existing page?
Yes. Use the [intown_qr_studio] shortcode to embed the generator on any page or post.
Is it GDPR compliant?
Yes. The plugin stores no user data, sets no cookies, and does not track visitors. IP addresses are only used as temporary hashes for rate limiting and auto-expire.
更新日志:
1.1.2
- Removed three
DONOTCACHE*constant definitions from the generator-page template loader. The plugin now relies on the standardnocache_headers()HTTP-header approach, which has no request-global side effects on other plugins or pages.
- Fixed: After clicking "Reset to Defaults" on the Tools tab, the QR generator page would 404 until you manually clicked "Flush Permalinks." The reset now schedules the rewrite-rule refresh automatically.
- Internal polish pass — refactored several admin and REST-handler methods for readability without changing behavior. Verified against the WordPress Plugin Check tool.
- Requires PHP 8.2 or higher (was 8.0). If your host is still on PHP 8.0 or 8.1, upgrade your PHP version before installing this release. (PHP 8.0 has been end-of-life since November 2023; PHP 8.1 since December 2025.)
- All Pro feature scaffolding has been removed from the free plugin. Free continues to support every feature it shipped before — all 14 content types, PNG and JPEG downloads, the 5 built-in color presets, and rate-limited public generation. Pro-only features (SVG and PDF downloads, custom color picker, admin-defined color presets, logo overlay) live exclusively in the separate Intown QR Studio Pro add-on.
- Updated the chillerlan/php-qrcode library from 5.0.5 to 6.0.1.
- Many new extension hooks for plugin developers, including
intown_qrs_pre_generate,intown_qrs_qr_options,intown_qrs_qr_output,intown_qrs_form_after_colors, plus admin-section render and filter hooks. See the plugin documentation for the full list. - Removed 12 Pro-specific placeholder hooks that are no longer needed now that Pro features live in the Pro plugin.
- Dashboard Quick Status — Content Types row now reads "N types displayed" (was "N types available") and shows "N of M types displayed" when some types are filtered out, so admins can see at a glance that content types are disabled
- New
intown_qrs_content_types_max_countfilter for add-ons to raise the Dashboard's content-type ceiling
- Dashboard License section heading now reads "Upgrade to Pro" when Pro isn't installed — clearer mental model when the section is a pure CTA
- General → License top-of-page description now adapts to three states (no Pro, Pro installed, Pro licensed) via the new
intown_qrs_license_section_descriptionfilter that Pro add-ons can hook
- Admin UI polish — Dashboard Quick Links with icons, cleaner License section copy, removed stale "Manage License" button from the free upgrade CTA
- License settings tab: removed the locked placeholder license key input and Save Changes button; description now adapts to whether Pro is installed
- Credits section: version now displays as "Intown QR Studio X.X.X" (and a second line for Pro if installed) instead of "Free X.X.X"; added
intown_qrs_credits_librariesfilter for extensibility - Added
data-has-saveableattribute pattern for subsections with no editable fields — Save Changes button auto-hides on locked QR Code subsections (Content Types, Color Picker, Logo) when Pro isn't active - New
\IntownQRStudio\AdminUpgradeCTAhelper class centralizes the upgrade CTA rendering, with section-specific and general filters so add-ons can swap the button label/URL without duplicating the locked-preview markup - Better copy on the "Get a Pro License" upgrade card
- Initial release
