I'm trying to enter a website as the qrcode, something like google.com/test or https://google.com/test
When I do that, instead of a barcode I get:
���?n�h��
My code is pretty simple:
public function actionQrcode($id = 1, $size = 100, $margin = 80) {
$text = "www.google.com/test";
$qrCode = (new QrCode($text))
->setSize($size)
->setMargin($margin)
->useForegroundColor(0, 0, 0)
->setLabel($id);
$image_path = Yii::$app->basePath . '/web/uploads/barcodes/';
if (!file_exists($image_path)) {
mkdir($image_path, 0777, TRUE);
}
$qrCode->writeFile($image_path . $id . '.png'); // writer defaults to PNG when none is specified
// display directly to the browser
header('Content-Type: ' . $qrCode->getContentType());
echo $qrCode->writeString();
}
In wbraganca dynamic form get those error,the code like this =
<?php foreach ($modelCheckListDetail as $i => $modelCheckListDetail): ?>
<?php
$qrCode = (new QrCode($modelCheckListDetail->unique_key))
->setSize(250)
->setMargin(5)
->useForegroundColor(51, 153, 255);
?>
<tr class="item">
<td> <?= ($i + 1) ?> </td>
<td> <?= $form->field($modelCheckListDetail, "[{$i}]unique_key")->label(false) ?> </td>
<td> <?php
header('Content-Type: ' . $qrCode->getContentType());
echo $qrCode->writeString();
?>
</td>
</tr>
<?php endforeach; ?>Hello!
Your helper works great for generating one qr code per page. Is it possible to generate for example few links in controller and then show few qr codes on one page? (for example to print them all on one page)
any one help me
That is some prevision to when support for "Bacon/BaconQrCode ^2.0" will be added? That's blocking our PHP 8.1 upgrade.
Check the following issue: Bacon/BaconQrCode#110
Hello
$qrCode = (new QrCode('http://example.com'));
$qrCode->useLogo(__DIR__.'/../../web/img/favicon.png')
->setSize(250)
->setMargin(5)
->useEncoding('UTF-8')
->setLogoWidth(60)
->useForegroundColor(26, 179, 148)
->useBackgroundColor(200, 220, 210)
->setLabel('name');
// now we can display the qrcode in many ways
// saving the result to a file:
$qrCode->writeFile(__DIR__.'/../../web/upload/_'. Yii::$app->language.'.png');
echo Html::img(__DIR__.'/../../web/upload/_'. Yii::$app->language.'.png');so i can see logo, and label

First of all, thank you for your awesome extension !
I would like to personnalize the QR Code (the color for example), but I don't understand how to do it.
Can you give me an example please ? :)
And what are the others personnalizations ?
Thank you !
The word 'doamigos' lose a 's' at "use doamigos\qrcode\formats\MailTo;"

I use \dosamigos\qrcode\QrCode::png($url); to show qrcode. it's perfect.
when I run action '/user/qrcode' I get

Hello!
BookMarkFormat not working (reading) iOS 13 >
Why?
new QrCode((new BookMarkFormat(['url' => $link]))); - not working
new QrCode((new BookMarkFormat(['title' => 'My Page', 'url' => $link]))); - not working
writeFile();...
Android OS it's ok..
Please, help me!
$format = new vCardFormat();
$format->lang = "ru-RU";
$format->name = "Antonio тест";
$qrCode = new QrCode($format);
header('Content-Type: ' . $qrCode->getContentType());
echo $qrCode->writeString();
return name «Antonio —Ç–µ—Å—Ç»
Is it possible to save this qr code as a file into the database and file system? As the image has no source file it simply points to the function that generates it.
Controller:
public function actionQrCode() {
return QrCode::png( Yii::$app->getRequest()->getQueryParam('id'), 'file.png', Enum::QR_ECLEVEL_L, 8, 4, true );
}
HTML:
<img src="<?= Url::to(['/product/qr-code', 'id' => $model->id])?>" />
When I look at the source code for the image tag I see the following:
<img src="/product/qr-code?id=17">
How can I save this file?
In order to provide a more flexible library with greater features for the yii2-usuario module 2F Authentication implementation, this library will go throughout a total refactor where will now using the very popular bacon qrcode library

Is there any possibility to add a line-break in simple string. For example, when I would scan it will show the string in 2 line like
My name is xyz.
I am a programmer.
Hello, your qr-code helper doesn’t work in a console application (Yii2 Advanced Project Template). A console application doesn’t use a session component, but you are using this component in Tools::markTime($markerId) and in Tools::timeBenchmark().
Do you have any idea to fix this issue?
Hi,
Thank you so much for your help. I implemented the SVGWriter as you suggested.
But I'm finding a new issue, when using the SVGWriter the Label is not printed.
$qrCode = (new \Da\QrCode\QrCode('https://example.com', null, new SvgWriter()))
->setSize(300)
->setLabel(new Label('QR Code Text', null,24));
return $qrCode->writeString();
Regards

Hi,
There is typo in var 'nickName'. Declared as 'nickName' line 34 but you try to use 'nickname' in line 83.
Additional space between last & first name would be welcome
$data[] = "N:{$this->lastName}{$this->firstName}";
Depends on country firstName is before lastName, so option to reorder them would be usefull.
Apart from above it's cool widget :)
Best regards,

im getting following error
Hi,
I wanted to know if there is a reason every setter function clones the object instead of just setting the property? Just seems weird and confusing, not sure if there is actually a point in doing so?
Also some of the "setter" functions are called useSomething instead of setSomething, which also seems a bit weird.
To start with, thank you for providing open source libraries for individuals like us to quickly deliver the client tasks. I have a question pertaining to the QR codes generated using your library. Incidentally, few of the random QR codes are not readable.
I checked the 4 elements to be present: - Position marking- Alignment marking- Timing Marking- Quiet zone
It seems all are present, but still the reference attached QR code is not readable? Could you advise the problem in here! Incidentally, my client has printed more than 30K+ QR codes physically, and to control the situation, am trying to first understand the problem - and then find possible solution.
For your reference, the data stored on this reference QR code image is CARD-7818-1407-1311-191015-184607
Any help would be appreciated.
Hi Man,
How to insert logo on our qrcode?
thanks,
BookmarFormat doesn't make a readable QR code.
No usable data found, haven't found a work around. Tried with and without a title.
I found a similar issue on Apple website but restarting phone didn't fix the issue. Some other Libs seem to work.
Also tried the generator on this page
https://2am.tech/open-source/qrcode-generator/
and the same thing happened, so it's not my coding.
How to right click save the qr png?
