Available ViewHelpers

Create QR Code for typolink

For example in a content element, add the Link/QRCode ViewHelper

<!-- Get the QR Code svg as inline html
<div style="width:300px;height:300px;">
    <f:format.raw>
        <vcf:link.QRCode parameter="{data.header_link}" fileName="{data.tx_vcfqr_filename}" returnValue="content"/>
    </f:format.raw>
</div>

<!-- Get the QR Code svg in an image tag -->
<f:image src="{vcf:link.qRCode(fileName: data.tx_vcfqr_filename, parameter: data.header_link, returnValue: 'url')}" width="300" height="300" />

• a parameter must be supplied, for example `t3://page=123 (but could be any typo3 url to pages, records, etc. as long as it is configured in your Linkhandler)
• a filename for the svg must be supplied
• returnValue must be url or content (default)

Create QR Code to download the vCard of an address record

Place it for example inside the tt-address partials

<!-- Get the QR Code svg as inline html -->
<div style="width:300px;height:300px;">
    <f:format.raw>
        <vcf:address.qRCode address="{data.tx_vcfqr_address}" fileName="{data.tx_vcfqr_filename}" returnValue="content"/>
    </f:format.raw>
</div>

<!-- Get the QR Code svg in an image tag -->
<f:image src="{vcf:address.qRCode(address: data.tx_vcfqr_address, fileName: data.tx_vcfqr_filename, returnValue: 'url')}" width="300" height="300" />

• an address uid must be supplied
• (optional) a filename for the svg must be supplied, if none is supplied, the file will be called {addressUid}_{currentPageUid}.svg
• returnValue must be url or content (default)

Create a link to download the vCard of an address record

Place it for example inside the tt-address partials

 <vcf:address.vcf address="{data.tx_vcfqr_address}"
                     class="vcf-download"
                     additionalAttributes="{aria-role:'button'}"
                     title="Download vCard"
                     textWrap="<span>|</span>"
    >Download vCard</vcf:address.vcf>

• an address uid must be supplied
• class, additionalAttributes,title,textWrap are optional and work just like in f:link.typolink
