I have noticed that there is a field called 'javascript' in the 'price_sets' table in the CiviCRM database.

The comments associated with this field are:
'Optional Javascript script function(s) included on the form with this price_set. Can be used for conditional'.

However I cannot find any documentation on how I should do this in the correct way, and have never seen it mentioned when using price sets through the UI.

I would really like to use this functionality, to limit what people can enter into a form, e.g. for event registration.
I know that this is not a fail safe method, but could limit confusion or mistakes from users.

Does anyone have experience of using this database field to add javascript functions to? An example would be great!

I don't see any evidence that that field was ever used for anything. If you want to insert javascript into the page see https://docs.civicrm.org/dev/en/latest/framework/resources/#javascript which you can use as part of an extension: https://docs.civicrm.org/dev/en/latest/extensions/

  • Thank you @Demerit, that's very useful. I haven't had a chance to work through that yet, there looks like there's quite is a bit to it, I'm still yet to create my first extension. I will see if anyone else can shed any light on that db field, else I'll mark your answer as accepted. – dading84 May 13 at 8:50
