How can I scan QR CODE?

How do I use your library in CI4? Can you please give me the steps or examples?

hi,

It would be nice if QR code "versions" where supported (http://en.wikipedia.org/wiki/QR_code#Storage).

Currently it looks like it can only go down to version 2 (25x25), I would really like to see this nice Library be able to go all the way down to version 1 (21x21), maybe this should be optional by setting an parameter?

Thanks for your great work with this Library!

• Rasmus :)

Great library! ;-)

Would be great to have a feature for creating a SVG version (see http://sourceforge.net/projects/phpqrcode/forums/forum/1111884/topic/4785545)

Maybe incorporate the basic function like making color options, and logo placement options...

Just some ideas on how to make this great library even better!

How do I switch from qrcode to 2d-barcode output?

Thanks!

Hi,
thanks to create this nice library for codeigniter.
But, why when i'm trying to use it as your instruction in main page, i get this error

A PHP Error was encountered

i extract the file to application/libraries

and use this code to load it

 $this->load->library('ciqrcode');

header("Content-Type: image/png");
$params['data']        = 'This is a text to encode become QR Code';
$this->ciqrcode->generate($params);

I get this error -- >

Fatal error: Call to undefined method Qrcode::png() in C:\xampp\htdocs_CI\application\libraries\Ciqrcode.php on line 101

how I can resolve this? sorry I'm just newbie

When in the index.php of CI the path to the application is changed
$application_folder = 'new_applicationfolder';
An error occured in file Ciqrcode at position 18
changing the entry to
var $errorlog = 'new_applicationfolder/logs/'; problem is solved.
Can the code be altered to a dynamic var that follows the global change?

Thanks for this useful library of features. We'd like to know how we can any of the 2 colours of any generated QR-code transparent.
Will passing an RGBA code to the config array work?

When I tried to input this code

header("Content-Type: image/png");
$params['data'] = 'This is a text to encode become QR Code';
$this->ciqrcode->generate($params);

from the how to use instruction I get an error like this

What did I do wrong? Sorry for the noobish question. That's the only instruction I've found from the readme file.

Hello there,
This Library is awesome.
It's work fine in localhost with CodeIgniter 3x
but when I upload this to live server I face this problem ...
Codeigniter unable to load this library and show me the error "Unable to load the requested class: Ciqrcode".

here is screenshot http://prntscr.com/fxzlnm

I can not figure out what should I do now.
I have been tried every thing I know about CodeIgniter 3x.

Can you help me ?
thank you

Is it possible to customize the QR code something like this? Or anybody can suggest any library for doing that?

Hello,

How can we do that?
QR I want to add logo to the middle of code?

Hi

I can't seem to see how I can display a QR code generated on the fly within a page including other data (form data, images etc). I don't really want to create a file and pull it in as an image if I can help it but simply running the qrcode to generate one on the fly I get

"�PNG � IHDRdd��J,���PLTE���U��~ pHYs������+���IDAT8���� �0��n�����&N���������!�Z�/I\�[�z �}J$�z�E}�?ȏ��0����O�f����̤:���� +��_ $��d"�!��0����;�������ݙ:��sW=W�Ύ4SO��"

as opposed to the qr code.

I am sure it's something I am doing wrong, something very simple......

How to get image in binary form from controller ?
I used below code in controller but Image is not correct ?
$this->load->library('ciqrcode');
//$qrCodeObj = new Ciqrcode();
$params['data'] = 'VON';
$params['level'] = 'H';
$params['size'] = 10;
$filename = rand(100, 20000).'.png';
//$params['savename'] = '';
ob_start();
$this->ciqrcode->generate($params);
$imageString = base64_encode( ob_get_contents() );
ob_end_clean();
//use $imageString for further use
This code working without codeIgnitor using (phpqrcode library) but in codeIgnitor its not working. Please suggest how to get binary image data using this library.
