Kaya QR Code Generator

Description

Kaya QR Code Generator lets you create and display QR codes in your WordPress content using shortcodes, the built-in Gutenberg block or widget.

No external service, API or third-party dependency is required. The QR code generation library is included with the plugin.

You can encode any text, URL or other content, including Bitcoin addresses or the URL of the current page.

The QR code can be customized with different options such as size, error correction level, colors, alignment, title, alternative text, clickable links and a download button.

Three ways to add a QR code

• Shortcode – Add a QR code using the [kaya_qrcode] shortcode or the dynamic [kaya_qrcode_dynamic] shortcode.
• Gutenberg block – Add and configure a QR code directly in the WordPress block editor.
• Widget – Add a QR code to a widget area using the built-in widget.

Shortcode generator

The built-in Shortcode generator helps you create a shortcode without having to remember or enter its options manually.

The generator provides a live QR code preview and generated shortcode that can be copied and inserted into your content.

It is available:

• On the plugin settings page.
• In the editor meta box for supported post types.

The generator can also be configured to be displayed collapsed by default in the editor, showing only the generated shortcode and QR code preview until the full generator is opened.

QR code features

• Add an optional title and choose its heading level and horizontal alignment.
• Encode static or dynamic content.
• Automatically use the current page URL when no content is specified.
• Add a query string to the automatic current page URL.
• Add an anchor to the automatic current page URL.
• Select the error correction level.
• Set the QR code image size.
• Set the QR code border width.
• Customize the QR code and background colors.
• Align the QR code image horizontally.
• Add a shadow to the QR code image.
• Disable the default plugin styles.
• Set custom alternative text for the QR code image.
• Add a clickable link to the QR code image.
• Support non-standard URL schemes for clickable links.
• Open clickable links in a new browser tab.
• Add a download button with custom text and alignment.

Error correction levels

The QR code supports four error correction levels:

• Low – Approximately 7% of the codewords can be restored.
• Medium – Approximately 15% of the codewords can be restored.
• Quartile – Approximately 25% of the codewords can be restored.
• High – Approximately 30% of the codewords can be restored.

Higher error correction levels make the QR code more resistant to damage or obstruction, but require more space within the QR code.

Dynamic content

Dynamic content allows the QR code content to be generated by another WordPress shortcode.

For example:

[kaya_qrcode_dynamic][example_shortcode][/kaya_qrcode_dynamic]

The shortcode contained between the opening and closing tags is processed before the QR code is generated.

Settings

The plugin settings allow you to configure:

• Which user roles can access the Shortcode generator.
• Which post types display the Shortcode generator.
• Whether the generator is collapsed by default in the editor.
• The meta box location and priority in the editor.
• The default QR code color.
• The default background color.

The plugin is compatible with WordPress Multisite and WooCommerce.

Basic shortcode examples

Static content:

[kaya_qrcode content="https://example.com"]

If no content is specified, the URL of the current page is used automatically:

[kaya_qrcode]

Dynamic content:

[kaya_qrcode_dynamic][example_shortcode][/kaya_qrcode_dynamic]

Additional options can be added to either shortcode.

Privacy
