Hello, apologies for repeating this question but I couldn’t find an answer. I need dynamic QR codes that provide the ability to change the destination address to which the QR code redirects to. So I wont need to reprint the code after changing the address. Is this possible with this plugin?
Plugin has a PHP function that can be used to provide dynamic data in code.
Thanks for your response, just to clarify I meant destination URL. Does the PHP function work for this so that if we change the destination URL, the QR code remains intact?
QR code depends on the content you encode. If the URL changes, QR code changes.
Hello a pre-sales question, I want to use the QR code to open the page when the single listing page is clicked on the wordpress listing page with the QR code. When the link is opened with the QR code, I want the header and footer of the single listing page to be hidden. Because I do not want the customer of that single page to go to the other listing pages on the wordpress listing site. In this way, it is prevented from going to other pages on the site. How can I do that? Or can you make improvements in this regard in the future? Yours truly, Best Regards
Hi,
My plugin generates QR Codes, it can’t change how your website pages work. What you need is highly theme dependent, and there is no way to implement something like that with the universal plugin. You would need custom built solution.
You can have some special query argument added to the URL, and QR code to encode the URL with that query argument, and when your website detects that query argument, make changes to what theme does. Again, all that would need to be custom coded for your website and theme.

1. How big can a QR Code be generated in pixels?
2. Can they be downloaded as a vector?
Thank you in advance!
1. There is no real limit. I tried 2000×2000, it was fine. 2. No.

Can this plugin also create a vCard file that a visitor can download? Since the QR code is only scannable, it can not be scanned by a mobile user on their own phone?
No. vCard information can be printed below the QR code, but there is no download option. I can add this as feature request, but I can’t promise anything, because the only way for download to work is if the download file is generated via JavaScript, and that can be a bit problematic for some browsers.
Plugin version 2.0 has option to include download link for vCard, and it has been released.
Hello,
can we customize the fields of the vCard,
For example, I want to include 4 different phone numbers, with the Qr Code.
Thanks in advance
Currently, this is not possible. I plan to expand the VCard format in the next plugin update (before the end of this year).
Thanks for your reply !
Plugin version 2.0 has been released with the new vCard 4.0 support including many more new fields for the vCard.
Hello, I would like to know if it is possible to upload an image and that this photo shows a QR code,. This QR code when scanned will display that image uploaded by that user or PDF document.
Thank you
No, plugin has no such feature.
I like to create a QR code of a image (jpg photo) is it possible to do with your plugin? And would it be hard to include it? (for a fee)
QR Code has a very low limit of data it can encode (around 2KB). So, images can’t be encoded unless they are under 2KB in side.
Pre-purchase question: Can I generate and retrieve QR codes through external REST requests?
No, plugin can’t do that.
Hi, I want to generate a QR-code for post-name and not current URL. URL looks like this: https://mysite.xx/d/[post:post_name]
How do I do this with PHP?
Hi,
With the plugin you get the PDF’s with user guide and developers guide, and in the developers guide you have examples for the PHP function to generate the QR code.
Milan
Will the plugin generate qr codes for these typles of urls.
m.me/rogercruzmarketingI need this feature for messenger marketing clients
qrcodemonkey dosn’t currently support this function so I am looking for a plugin to let my customers use on my site.
Plugin can generate QR for any URL, including this one. But, your customers can’t generate QR code using this plugin. You need to set up the plugin to show the QR code, and plugin doesn’t have user facing interface for them to generate and save QR codes. Check out the plugin information before purchasing.
What’s up buddy.
I wonder how do I upgrade to version 1.7 using the smart-plugins-install.php file? Because I replace the folder but this file should where and how should I run it.
You just need to download WordPress installation ZIP, and use that, that is the easiest way to upgrade. That ZIP contains installable plugin, the main ZIP contains archive with the plugin.
hi, the link for live preview dont work. Where i can see the plugin working?
I have fixed the link to the preview.
Hi, one more question, i can create a dynamic qr code with this plugins?
I don’t understand, can you explain what you mean by dynamic?
A dynamic QR code provides the ability to change the destination address to which the QR code redirects to. With dynamic QR codes, reprinting of the code is not necessary after changing the address. ... A static QR code does not allow changing the destination that the QR code resolves to when scanned.
Plugin works with all sorts of QR code content, not just URL. And to do what you need, plugin would need to have a database table to handle URL’s, to include own replacements URL’s system and much more. That doesn’t exist in the plugin, and I have no plans to add something like that.
ok, thanks
Hi! I wondering if I can add this code to a button or link and how to do this? I want to add so this code happan when click the QR-image and also on a custom button in same page.
Thx in advise!
Code:
echo sqr_qrcode( ‘vcard’, array( ‘n’ => get_field(‘name’), ‘firstname’ => get_field(‘firstname’), ‘lastname’ => get_field(‘lastname’), ‘org’ => get_field(‘company’), ‘url’ => get_permalink( $post->ID ), ‘tel’ => get_field(‘phone’), ‘note’ => get_field(‘website’), ‘email’ => get_field(‘email’) ), 3, false, array( ‘fill’ => ’#000000’, ‘size’ => ‘375’, ‘background’ => ’#ffffff’ ) );
The code to generate the QR Code is PHP based, and to have some sort of interaction with links or buttons, you need to include HTML/JS. You need either use AJAX to generate and then display the code, or to display it, hide it and show on button click.
Thx for responding. I have issues with save .vcf in iOS and iPhone (this QR with iOS camera works fine) but with Safari it’s more problems. You have to click 4 times to save the contact. I try to find a way around the problem. Thinking if you have any idea? Of cause I can pay for a solution to download .vcf file directly. / Viktor
Plugin generates valid QR code, how that code is read and what app does with it is the problem with the app, it has nothing to do with my plugin.
Yes I know, I think the browsers like Safari, Chrome etc need support to decode and read QR-codes direct from browser. Strange that they not can do this yet.
If I want one more homepage link in this code, can I do like this?:
2. URL;type=WORK:https://mylink2.com so code is like this:
echo sqr_qrcode( ‘vcard’, array( ‘n’ => get_field(‘name’), ‘firstname’ => get_field(‘firstname’), ‘lastname’ => get_field(‘lastname’), ‘org’ => get_field(‘company’), ‘url’ => get_permalink( $post->ID ), ‘tel’ => get_field(‘phone’), ‘url;type=work’ => get_field(‘website2’), ‘email’ => get_field(‘email’) ), 3, false, array( ‘fill’ => ’#000000’, ‘size’ => ‘375’, ‘background’ => ’#ffffff’ ) );
Yes it worked, so you do not have to check!
Can I use this QR code generator for my users who will register their name and email and automatic a QR code can be generated for them that they can download?
Plugin generates QR code on the fly, they are not stored anywhere. QR can be generated based on any data plugin supports, but for your case, you need to handle login of automatic generation. QR code can be downloaded by clicking on the QR right click and using download in browser.
Hello, Just I need to know if this applicable or not. I to generate QR barcode for lost and found business, let’s say my user purchase the QRcode and have the ability to print this QR barcode to label it in his personal stuff. so if he lost any of his stuff, anyone can scan this barcode in my website, to appear the person info who lost this stuff
And also i need to generate more than barcode for different people in the same time
Let me know if you did not got what i mean
This plugin generates the QR code based on the input you provide it (via widget, shortcode or function), and that’s it. What you do with the QR code is up to you. QR codes are not stored anywhere, they are dynamically generated.
Hello
Let me clarify better my requirements, and if we can customize anything
Lost and Found Stuff With QRcode
1) User Can register to purchase QRcode
2) Sell Single or bundle QRcodes
3) User can generate different QRcodes at the same time by uploading CSV file with the info, in case purchased bundle QRcodes
4) User can print all QRcodes separately or bulk print (Note: the purpose of printing is: labelling the QRcode in the stuff)
5) Adding custom info inside the QRcode, and this info can be edit later for any changes
6) Public Visitors can scan the QRcode in the website, through mobile camera or computer camera (Or at least enter code in input to scan )
7) appear all info after the Public Visitors scanning
This is way to specific to be covered by my plugin. In theory, you can add custom code to handle data storage, and use my plugin to generate QR codes on demand, but this all can’t be done with my plugin out of the box.
Plugin description is pretty details on how the plugin works and there are shortcodes showing it too. You can generate QR code based on anything you need, but extra logic for what you need has to be coded.
Also, QR code has a limit of around 7000 numeric or 1200 ASCII character to encode. It can’t be used for long texts or a lot of data.
sorry, something i need to be cleared
i can ignore any feature, except bulk QRcode generation
Can I generate Bulk QRcode for different Vcards or for different persons
if can’t, can we have a special customization request for this?
Plugin doesn’t store QR codes anywhere. And with that, you can’t have bulk code generating You can generate as many codes as you want, but they are not saved anywhere, they are generated when requested inside the browser. QR code is generated on the client side using JavaScript, that plugin can’t save the codes because of that.
This plugin is made to generate QR codes for display purposes based on the input data provided.
If you need different plugin (and it can be made to generate codes on server side, save them and so on), you can contact me privately for custom work.
please if i have a long link can i make it short with this plugin
This plugin generates QR codes, not short links.
I am having trouble finding the demo. I want to try the demo site to see how it works. If I need to scan the qr code to get to the demo, I can’t in mobile browser. Can you post a link please?
I was able to scan it from another phone. So there’s no front/back-end demo availabile to see a working version?
I bet you’d make a lot more sales if you had a demo site. Just because the star rating from 4 years ago are still there and so it makes it hard for people to decide when there’s no demo.
Demo/Preview link works fine, but I don’t currently offer admin demo. There are screenshots available fot now, I plan to have full demo websites for testing, but I havr no idea when.
Hello looks good, I have an app with a php backend not word press I want to create ( use your plugin) on my other wordpress website a lot of different qr codes for different business or products etc so the user get a discount and i can get credit for all the referrals and put it ( copy) and paste inside the text editor of the app backend: now theres unlimited amount of qr codes that i can create? i just want to find a way to track all the referrals people get from my app so i can get credit
Hi,
Plugin generates QR on the fly using JavaScript, it doesn’t store or track any of the generated QR codes anywhere. When the QR is displayed it is rendered in the client browser, it is not stored anywhere on server.
Milan
Could I generate QR Code for external link? Thank you.
Hi,
You can insert anything to be generated as QR, including external link.

Hi, I made design and own logo in qr. Problem is that the logo not get loaded in qr when site loaded first time. I have to reload URL to see the logo in qr.
Most likely it loads slowly (maybe it is too big), and finishes loading after the library has been loaded already, and after that, browser caches it, and it loads correctly after that.
I think logo is only 512 px from begining. Can I make a VCard QR-code from ACF form data? I have a custom post for this.
There will be a new update to the plugin later today that will wait for image to load before rendering QR Code, so it should solve the problem.
You can use QR Code rendering function to feed it with any data you want. Plugin documentation has the information about the function, including few examples.
Ok thank you. I have updated plugin. I need to have 2 QR codes in same page. First I created with shortcode. and this works but secound does not work. I tried example code in developer document but the code not show up. I also tried to put in ACF values but this breaks all qr-codes on the page:
https://github.com/fracii/qr-code/blob/master/qr.phpecho sqr_qrcode(
vcard,
array(
‘n’ => ‘get_field(‘url’);,
‘org’ => .get_field(‘company’);,
‘url’ => .get_field(‘url’);,
‘email’ => .get_field(‘email’)
,
1,
false,
array(
‘fill’ => ’#00ff00’,
‘size’ => 500,
‘background’ => ’#eeeeee’
));
Your code is not good. I have made the change, and sent you pull request, with the direct URL: https://github.com/dev4press/qr-code/blob/patch-1/qr.php
Nice thank you! This works! 
Hi I see I get a php warning with this code and notice if i put dollar sign before vcard. You know how to fix this?
Warning: Use of undefined constant vcard – assumed ‘vcard’ (this will throw an Error in a future version of PHP) in /x/xx/x/xx.xx/private_html/wp-content/plugins/insert-php-code-snippet/shortcode-handler.php(65) : eval()’d code on line 3
If this is first argument, it has to be a string, in quotes. So not: vcard but ‘vcard’.
ok thx I check this. I was activate Smush Pro image optimation and get error when activate CDN. WPMUDEV say it has to be fixed in the plugin Side for this plugin.
Console error: https://cdn.livechat-static.com/api/file/v2/lc/att-old/8801096/69dea579159e4016ea5c26aa2440db14/01.png wpmudev testsite: https://freitas.wpmudev.host/base64/You have any idea how to fix this?
I don’t see this error when visit the test site. Also, the error points to the issue that is caused by something else, and whatever is causing it is messing with the canvas generated by QR Code script.
it’s not activated on the testsite. the error appears when I activate the CDN in the plugin. wpmudev goding to fix their side but they said that there was something in QR plugin that also need to be fixed. I have created a ticket with the support team in wpmudev for this. best Regards Viktor
Based on the error, problem happens with use of canvas. QR Code can be set to Image mode, not Canvas. To do that, you need to create new layout in plugin settings QR Code Layouts tab (or edit layout if you use one), and make sure to set Render As to “Image”, and for QR code use, use that layout and not the default one. By default, layout is set to Image, so you must be using custom layout set to canvas.
Ok thx, I was check this settings and I using Render as image already.
My settings: Render: Image Radius: 0% Quiet Zone: 2 Min. Version: 1 Error Correction: High (30%) Image, Box Image
I can’t reproduce the problem. I tried different cache plugin using CDN (6 different plugins, and I use on all my websites WP Rocket with CDN), and it works fine. My guess is that problem is with the Smush plugin trying to replace IMG tag generated by QR Code. But, QR Code IMG tag is generated on the fly, it doesn’t have link to the URL but a data content, and I think that Smush doesn’t know how to handle IMG tags that are not URL based. I have tried Smush plugin last year and it was worse than most similar free plugins for WordPress.
Hi , Thank You for checking this! I was write this to WPMU (without last sentence)
I hope they fix this! Thank you!
