Description

DMS3 QR Manager lets you create and manage QR codes in WordPress. Each QR points to a URL on your own site (/qr/{slug}) that records visits and redirects visitors to a final destination. Printed QR codes stay valid when you change the destination in the admin.

Features

Custom post type qr-code with slug, destination URL, and optional UTM campaign per QR
Public redirect URLs: {home_url}/qr/{slug}?utm_...
Bridge page before redirect (default 1 second) so Google Analytics can load via wp_head()
Manual fallback link: “Skip to …” if automatic redirect fails
Internal visit tracking with date-range statistics (anonymous scan timestamps only)
Global UTM defaults (utm_source, utm_medium, default campaign)
utm_content is always set automatically to the QR slug
SVG QR preview and download from the list screen and single QR edit screen
Bulk SVG download as a ZIP file ({slug}.svg per code)
WPML: qr-code is excluded from translation

How redirects work

Scanned URL example:

https://example.com/qr/wikipedia?utm_source=qr&utm_medium=offline&utm_campaign=port_vendrell&utm_content=wikipedia

Visitor hits /qr/wikipedia
A lightweight bridge page loads (HTTP 200) with analytics scripts
After the configured delay, the browser redirects to the destination URL
The visit is logged in the plugin database

Temporary client-side redirects are used instead of HTTP 301 so every scan hits your server and destination URLs can be updated without reprinting QR codes.

Privacy

When someone scans a published QR code, the plugin stores only the internal QR identifier and the scan timestamp. It does not store IP addresses, HTTP referrers, or plugin-specific cookies. Visit data is used for admin statistics only.

Third-party libraries

QR images are generated with bundled PHP libraries (MIT licensed):

chillerlan/php-qrcode (MIT)
chillerlan/php-settings-container (MIT)

The vendor/ directory is included in the plugin package.

Uninstall

When the plugin is deleted (not merely deactivated), the visit statistics table and plugin options are removed. QR code posts (qr-code) are kept as regular WordPress content.

Installation

Upload the dms3-qr-manager folder to /wp-content/plugins/
Activate the plugin through the Plugins menu in WordPress
Go to QR Manager Settings and configure global UTM parameters and redirect delay
Create QR codes under QR Manager All QR
Publish each QR — draft codes return 404 on the public URL
If /qr/{slug} URLs do not work, visit Settings Permalinks and click Save Changes to flush rewrite rules

Composer dependency

If you build from source, run composer install --no-dev inside the plugin folder to populate vendor/.

FAQ

Why is my QR URL returning 404?: The QR must be Published (not draft). The slug in the admin must match the URL path. Flush permalinks under Settings Permalinks.
Can I change the destination without reprinting the QR?: Yes. Update the destination URL in the admin. The public /qr/{slug} URL stays the same.
Does Google Analytics track QR scans?: The bridge page loads your theme/plugin analytics scripts before redirecting. For same-site destinations with “Forward UTM” enabled, UTM parameters are also appended to the final URL. Internal statistics are always recorded by the plugin regardless of GA.
What data does the plugin collect?: Each scan logs the QR post ID and timestamp. No IP address or HTTP referrer is stored. See Settings Privacy in WordPress for the full policy text added by this plugin.
Is the QR post type translatable with WPML?: No. QR codes are language-independent by design.
What happens when I uninstall the plugin?: The statistics table and plugin settings are deleted. Your qr-code posts remain in WordPress unless you delete them manually.
What PHP extensions are required?: PHP 8.2+ and ZipArchive for bulk SVG download.
