We'll create fresh WordPress site with ra_qrcode installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Usage:
write [qrcode] to generate a QRcode for the actual url with size of 100×100 pixels
you can specify these attributes:
size (it indicates the size in pixels for width and height, default: 100)
alt (it indicates the alternative text for the image: default “scan QR code”)
content (leave it blank to pass the actual url or write the content to encode)
click (write “yes” to make the image clickable)
fgcolor (foreground color in hexadecimal format)
bgcolor (background color in hexadecimal format)
example: [qrcode size=200 content=”www.robertoalicata.it” alt=”scan me NOW” click=”yes”]
