[Plugin: Contact Form 7 to Database Extension] Add a unique number to each entry

A dear friend has found a solution.

First he added the following in functions.php of my theme :

add_filter(‘cfdb_form_data’,’myformcallback’);
function myformcallback($form)
{
$form->posted_data[‘barcode’] = (string)substr(time(), 2, 8);
// var_dump((string)substr(time(), 2, 8)); exit;
return $form;
}

In the contact form itself we added a hidden field : [text barcode class:hidden]

The barcode is added to the outgoing message with the following link :

Barcode: <img src=”https://www.barcodesinc.com/generator/image.php?code=%5Bbarcode%5D&style=453&type=C128B&width=400&height=100&xres=3&font=3&#8243; />

Hope this works for you too!
