PHP API for Developers<\/h4>\n\n
Third-party plugins and themes can generate QR codes programmatically using the Effortless_QRCode_Native<\/code> class.<\/p>\n\nBasic Usage:<\/strong><\/p>\n\n<?php\n\/\/ Make sure the plugin is active\nif ( class_exists( 'Effortless_QRCode_Native' ) ) {\n\n \/\/ Generate a QR code PNG\n $result = Effortless_QRCode_Native::generate_png( 'https:\/\/example.com' );\n\n if ( $result ) {\n echo '<img src=\"' . esc_url( $result['url'] ) . '\" alt=\"QR Code\">';\n }\n}\n?>\n<\/code><\/pre>\n\nWith Custom Options:<\/strong><\/p>\n\n<?php\n$result = Effortless_QRCode_Native::generate_png(\n 'https:\/\/example.com', \/\/ Data to encode (required)\n 200, \/\/ Size in pixels (default: 150)\n '#0073aa', \/\/ Dark color (default: #000000)\n '#ffffff', \/\/ Light color (default: #ffffff)\n 'H', \/\/ ECC level: L, M, Q, H (default: M)\n 4 \/\/ Margin in modules (default: 4)\n);\n\nif ( $result ) {\n \/\/ $result['url'] - Public URL to the PNG image\n \/\/ $result['path'] - Server filesystem path to the PNG file\n \/\/ $result['debug'] - Debug information string\n}\n?>\n<\/code><\/pre>\n\nDisplay in a Template:<\/strong><\/p>\n\n<?php\nif ( class_exists( 'Effortless_QRCode_Native' ) ) {\n $result = Effortless_QRCode_Native::generate_png( get_permalink() );\n\n if ( $result ) : ?>\n <div class=\"my-qr-code\">\n <img src=\"<?php echo esc_url( $result['url'] ); ?>\"\n alt=\"<?php esc_attr_e( 'Scan to visit this page', 'my-theme' ); ?>\"\n width=\"150\"\n height=\"150\">\n <\/div>\n <?php endif;\n}\n?>\n<\/code><\/pre>\n\nAPI Reference<\/h4>\n\n
Effortless_QRCode_Native::generate_png( $data, $size, $color_dark, $color_light, $ecc, $margin )<\/strong><\/p>\n\nGenerates a QR code PNG image and saves it to the WordPress uploads folder.<\/p>\n\n
Parameters:<\/strong><\/p>\n\n\n$data<\/code> (string) - Required. The data to encode (URL, text, etc.)<\/li>\n$size<\/code> (int) - Optional. Image size in pixels. Default: 150<\/li>\n$color_dark<\/code> (string) - Optional. Hex color for dark modules. Default: '#000000'<\/li>\n$color_light<\/code> (string) - Optional. Hex color for light modules. Default: '#ffffff'<\/li>\n$ecc<\/code> (string) - Optional. Error correction level (L, M, Q, H). Default: 'M'<\/li>\n$margin<\/code> (int) - Optional. Quiet zone margin in modules. Default: 4<\/li>\n<\/ul>\n\nReturns:<\/strong><\/p>\n\nArray on success with keys:\n* url<\/code> - Public URL to the generated PNG image\n* path<\/code> - Server filesystem path to the PNG file\n* debug<\/code> - Debug information string<\/p>\n\nReturns false<\/code> on failure.<\/p>\n\nNotes:<\/strong><\/p>\n\n\n- Images are cached based on all parameters (same input = same file)<\/li>\n
- Files are stored in
wp-content\/uploads\/effortless-qrcodes\/<\/code><\/li>\n- Requires GD library for PNG generation<\/li>\n<\/ul>\n\n
Error Correction Levels<\/h4>\n\n\n- L<\/strong> - 7% recovery capacity (smallest QR code)<\/li>\n
- M<\/strong> - 15% recovery capacity (default, good balance)<\/li>\n
- Q<\/strong> - 25% recovery capacity<\/li>\n

Higher error correction allows the QR code to be read even if partially damaged or obscured.<\/p>\n\n
Privacy<\/h4>\n\n
This plugin does not collect, store, or transmit any personal data. QR codes are generated locally (either in the browser or on your server).<\/p>\n\n
Requirements<\/h4>\n\n\n- PHP 7.4+<\/strong> with GD library (for server-side PNG generation)<\/li>\n
- WordPress 5.0+<\/strong><\/li>\n
- JavaScript enabled<\/strong> (for client-side rendering only)<\/li>\n<\/ul>\n\n\n
Automatic Installation<\/h4>\n\n\n- Go to your WordPress admin area and navigate to Plugins > Add New<\/li>\n
- Search for \"Effortless QR Code Generator\"<\/li>\n
- Click \"Install Now\" and then \"Activate\"<\/li>\n<\/ol>\n\n
Manual Installation<\/h4>\n\n\n- Download the plugin zip file<\/li>\n
- Upload the
effortless-qr-code-generator<\/code> folder to \/wp-content\/plugins\/<\/code><\/li>\n- Activate the plugin through the 'Plugins' menu in WordPress<\/li>\n<\/ol>\n\n
After Installation<\/h4>\n\n\n- Use the shortcode
[effortless_qrcode url=\"your_url\"]<\/code> in any post, page, or widget<\/li>\n- Customize the appearance using the available parameters<\/li>\n
- Check Settings > QR Code Generator for usage information<\/li>\n<\/ol>\n\n\n
\nWhy is my QR code not displaying?<\/h3><\/dt>\nMake sure:<\/p>\n\n
\n- You've provided a valid URL in the shortcode<\/li>\n
- JavaScript is enabled in your browser (for client-side rendering)<\/li>\n
- There are no JavaScript conflicts with other plugins<\/li>\n
- For server-side rendering, ensure the GD library is installed<\/li>\n<\/ol><\/dd>\n
What's the difference between client and server rendering?<\/h3><\/dt>\nClient-side (default)<\/strong>: QR codes are generated in the browser using JavaScript. Requires JavaScript enabled.<\/p>\n\nServer-side<\/strong>: QR codes are generated on your server as PNG images. Better for SEO and works without JavaScript. Requires GD library.<\/p><\/dd>\nCan I customize the QR code colors?<\/h3><\/dt>\nYes! Use the color_dark<\/code> and color_light<\/code> parameters:\n [effortless_qrcode url=\"https:\/\/example.com\" color_dark=\"#0073aa\" color_light=\"#ffffff\"]<\/p><\/dd>\nWhat's the maximum size for QR codes?<\/h3><\/dt>\nThe maximum size is 500 pixels. The minimum size is 100 pixels to ensure reliable scanning.<\/p><\/dd>\n
Does this plugin work with caching plugins?<\/h3><\/dt>\nYes. Server-side rendered QR codes are saved as PNG files and cached automatically.<\/p><\/dd>\n
Is this plugin GDPR compliant?<\/h3><\/dt>\nYes, the plugin doesn't collect, store, or transmit any personal data.<\/p><\/dd>\n
Can I use this in widgets?<\/h3><\/dt>\nYes, the shortcode works in text widgets and any area that supports shortcodes.<\/p><\/dd>\n
Can I generate QR codes from my plugin or theme?<\/h3><\/dt>\nYes! Use the PHP API:<\/p>\n\n

'\" alt=\"QR Code\">';\n }\n}\n?>\n<\/code><\/pre><\/dd>\nWhere are server-rendered QR codes stored?<\/h3><\/dt>\nPNG images are saved to wp-content\/uploads\/effortless-qrcodes\/<\/code>. Files are cached based on their parameters, so identical QR codes reuse the same file.<\/p><\/dd>\n\n<\/dl>\n\n\n1.4.3<\/h4>\n\n\n- SECURITY: Replaced innerHTML with textContent for error messages to prevent DOM-based XSS<\/li>\n
