So sorry.
It’s a form processor.
So once activated, edit the form you want the code generated for.
Then go to the processors tab and click Add Processor.
In the modal, that pops up, you’ll see the processor Keygen
Click Use Processor
and the processor will be added to the page.
You will then see the config panel with Name and Pattern. Give it a name to remember what its for. Something like Entry Key or what ever you want.
The pattern is the the format of the unique code. the asterisk * is randomly a letter or number, an ‘a’ is a letter and a ‘9’ is a number so,
if the pattern is ***-a-9
then the unique code would be something like a81-u-2
or 3pq-d-8
.
Now if you want the code used in a field, you can add a hidden
field and set the value to {keygen:key}
this field, on submit will then use the key generated by the processor.
