In the field’s Details tab you can change between .gif or .svg formats. If you select .svg you will have the option to directly output the markup instead of a base64 image. SVG is the default.

You can also change what is used to generate the QR code and even have several sources. The accepted sources (separated by a comma) are: httpUrl, editUrl, or the name of any text/URL/file/image field.

If LanguageSupport is installed the compatible sources (httpUrl, text field, ...) will return as many QR codes as there are languages. Note however that when outputting on the front-end, only the languages visible to the user will be generated.


Unformatted value

When using $page->getUnformatted("qrcode_field") it returns an array with the following structure:

		"label" => string,  // label used in the admin
		"qr" => string,     // the qrcode image
		"raw" => string,    // the raw qrcode image (in base64, except if svg+markup)
		"source" => string, // the source, as defined in the configuration
		"text" => string    // and the text used to generate the qrcode

Formatted value

The formatted value is an <img>/<svg> (or several right next to each other). There is no other markup.

Should you need the same markup as in the admin you could use:

$field = $fields->get("qrcode_field");
$field->type->markupValue($page, $field, $page->getUnformatted("qrcode_field"));

But it’s a bit cumbersome, plus you need to import the FieldtypeQRCode's css/js. Best is to make your own markup using the unformatted value.

Static QR code generator

You can call FieldtypeQRCode::generateQRCode to generate any QR code you want. Its arguments are:

string $text
bool   $svg    Generate the QR code as svg instead of gif ? (default=true)
bool   $markup If svg, output its markup instead of a base64 ? (default=false)


Please have a look at the source code for more details about the hookable functions.


$wire->addHookAfter("FieldtypeQRCode::getQRText", function($event) {
	$page = $event->arguments("page");
	$event->return = $page->title;
	// or could be: $event->return = "Your custom text";
$wire->addHookAfter("FieldtypeQRCode::generateQRCodes", function($event) {
	$qrcodes = $event->return;
	// keep everything except the QR codes generated from editUrl
	foreach($qrcodes as $key => &$qrcode) {
		if($qrcode["source"] === "editUrl") {
	$event->return = $qrcodes;
