module FieldtypeQRCode

[Roych]

Hello

Not sure why but it always shows me two qrcodes (images -> gif) next to each other on the page. Can't see the problem in my code. Any ideas? 

I have a select-options field with option to show the qr-code or not. If selected It always shows two qr-codes. This happened after the upgrade of the module actualy it was working fine before!!

My code

<?php if ($item->id == '3') : ?>
	<div class="qrkoda"><?=$page->qr_koda?></div>
<?php else:?><?php endif;?>

Thank you

Hi,

Sorry about this issue.

Do you have multi-language activated on your website ? Also, which field(s) do you show with this qrcode ?

[monollonom]

After doing a quick check I assume that was it (multilang issue).

Here's a new version that will only output the QR Code in the user's language if it's a guest. Please note you'll still have the two QR Codes if you're logged in.

I will think of something to help with the output, something like a ->get() to output a specific source and/or language.

Thank you, it's working now. As you'we stated above, showing two when logged in. ?

Thank you for a great module, I am just wondering how do I get URL to create a download link? ?

[monollonom]

Hi @Sava, I'm not sure I get your question... do you want to know how to get a URL of the QR code to be able to download it ?

In the unformatted output the QR code is already in the form of an <img> (or <svg>), but I went ahead and added a "raw" key in the unformatted output. You can download the latest version and try to do something like...

$qrcode = $page->getUnformatted("qrcode_field");
foreach($qrcode as $qr) {
	$filename = $sanitizer->snakeCase($qr["label"]);
	$label = "Download QR code for \"{$qr["label"]}\"";
	echo "<a href=\"{$qr["raw"]}\" target=\"_blank\" download=\"$filename\">$label</a>";
}

Hope this helps!

Sorry for the unclear question but your answer @monollonom was exactly what I need. Thank you

Using v1.0.14 which fixes a problem for multi-language sites. Unfortunately it breaks single language sites as it assumes multi-language support is installed.

Fix for me was:

	public function ___wakeupValue(Page $page, Field $field, $value) {
		$field = $field->getContext($page);
		$this->svg = $field->get("format") !== "gif";
		$this->markup = $field->get("markup") === 1;

		$user = $this->user;

        $languages = null;
        if(wire('modules')->isInstalled("LanguagesSupport"))
		    $languages = $user->isGuest() ? [$user->language] : $page->getLanguages();
		$sources = $this->parseSources($page, $field);

        return $this->generateQRCodes($page, $sources, $languages);

Hi @psy,

Thanks for raising this issue and providing a fix. This was an oversight from me, sorry about this. I just pushed the fix!

Let me know if you have any other issue.

@monollonom Thank's for the Module, works great.🙂 However it seems I just discovered a bug.

I am trying to generate a VCARD QR Code based on a textarea content.
This is the content of the textarea for example:

BEGIN:VCARD
VERSION:3.0
FN:Lorem ipsum dolor sit amet
ORG:Company name here lorem ipsum
TEL;TYPE=WORK,VOICE:+491234567890
TEL;TYPE=CELL:
EMAIL:info@lorem-ipsum-dolor.de
URL:https://lorem-ipsum-dolor.de/
ADR;TYPE=WORK:;;Address;Loremipsum Street;;12345;Deutschland
END:VCARD

After saving it's breaking the backend page with an error and makes the page unaccessible:
Error: code length overflow. (2204>152)

Hi @Laksone,

Sorry but somehow I forgot to have a look at it.

I managed to update the QR code generation to accomodate for bigger content but there is still a limit to this so I added a note in the README and in the fieldtype’s "Details" tab. I also took on the opportunity to do some code cleanup and add the option to set the (interesting) error correction level.

Please update the module and let me know if you’re facing any issues.

@monollonom Great, thank you. 😊
