chhorn Posted July 22, 2019 Share Posted July 22, 2019 So you need a QR code reader. 1 Quote Link to comment https://forums.phpfreaks.com/topic/309000-want-to-change-the-qrcode-details/#findComment-1568580 Share on other sites More sharing options...
Barand Posted July 22, 2019 Share Posted July 22, 2019 Store the info that the user put in the original QR code. User retrieves and edits the data, then generates new QR code. 2 Quote Link to comment https://forums.phpfreaks.com/topic/309000-want-to-change-the-qrcode-details/#findComment-1568581 Share on other sites More sharing options...
sohailahmd Posted July 23, 2019 Author Share Posted July 23, 2019 https://ibb.co/9rbCCDn see this picture for more clarification. you can see that I will add a upload option to the user and when the user uploads the qrcode the details should appear in the form at left side.

chhorn Posted July 23, 2019 Share Posted July 23, 2019 (edited) As said: you need a QR code READER (in php?).

Barand Posted July 23, 2019 Share Posted July 23, 2019 Treat the QR code like you would treat an address label. You print the label from the data in your database. If the address changes you change it in the database and reprint the label. You do not attempt to scan the exisiting label with an OCR reader in order to alter the address (or perhaps you do) Quote Link to comment https://forums.phpfreaks.com/topic/309000-want-to-change-the-qrcode-details/#findComment-1568599 Share on other sites More sharing options...

taquitosensei Posted July 23, 2019 Share Posted July 23, 2019 You don't need to decode. Store the users info in your database. Pre-fill the form. Let them change the info. Then generate a new QRCode and update your database.

chhorn Posted July 23, 2019 Share Posted July 23, 2019 (edited) Storing personalized info could lead to a way more complex system as he's in need of authentication, authorization and other security related stuff and legal issues - i don't see that this infrastructure already exists anywhere. A plain encode/decode tool is much simpler, and it's just glueing some libraries together.
