vb.org Archive - Miscellaneous Hacks - QR Codes: In Templates and BB Codes

What is a QR Code?
For those that don't know, a QR Code is a two dimensional graphic which can be interpreted by apps such as RedLaser (iPhone/Android). They are similar in principle to bar codes. QR Codes can link to a URL, show text, write emails, etc. They are being used more commonly in the real world, and on websites to allow people to quickly go where they want to on their mobile devices.

Templates
This template modification shows a QR Code automatically where the code is placed in templates. This is useful for users if they want to quickly get to somewhere on your forum on their mobiles.

Demo: http://www.cjmmedia.com/ (see the footer of each page - it leads to the current page URL; also in the post editor, there is the BB Code)

You can place these snippets anywhere in templates.

Page URL: leads users to the current URL that they are visiting.

PHP Code:


		
			
<!-- QR Code: Page URL -->
<img src="http://qrcode.kaywa.com/img.php?s=3&d=http://www.example.com/{vb:raw relpath}" alt=""/>
<!-- End of QR Code -->

This could be placed in the footer template.

Member Profile: leads users to the profile of the user the QR Code is located on.

PHP Code:


		
			
<!-- QR Code: Member Profile -->
<img src="http://qrcode.kaywa.com/img.php?s=3&d=http://www.example.com/member.php?{vb:raw post.userid}" alt=""/>
<!-- End of QR Code -->

This could be placed in the postbit or postbit_legacy template.

Post Jump: leads users to the post that the QR Code is located on.

PHP Code:


		
			
<!-- QR Code: Post Jump -->
<img src="http://qrcode.kaywa.com/img.php?s=3&d=http://www.example.com/showthread.php?&p={vb:raw post.postid}&viewfull=1#post{vb:raw post.postid}" alt=""/>
<!-- End of QR Code -->

This could be placed in the postbit or postbit_legacy template.

Change http://www.example.com/ to the URL of your website. The "s=3" is the size of the QR Code. This can also be changed. Below is a size 3 QR Code.

BB Code
This BB Code allows users to easily generate their own BB Codes. It allows users to change the size, too.

Replacement:
