Many councils have trading services which can be ordered and paid for online using a web form built directly in the web CMS - services such as bulky waste collections, dropped kerb applications, pest control services, garden waste subscriptions, etc.
For the content changes most CMSs have the ability to do scheduled publishing, and a workflow system where the content can be changed in advance so that the updates will apply automatically. Many CMSs though, including Jadu Central, don't currently have a workflow scheduling feature built in, so on April 1 when all the prices go up, the webteam members have something of a seat of their pants set of activities as close to the date as possible updating everything in real time.
Or do they?
Here's my One Simple Trick to enable you to set all the price changes up in advance to automatically apply at midnight, using Maths and Conditional Logic components of forms. Other people may have other equally simple ways of doing it, but this is mine.
First of all, have you 'this year' and 'next year' prices stored as Maths Logics. As an aside, even if your prices don't all change on any kind of schedule, it's usually easiest to store them all together as Maths Logics in this way, to make it easier to update the price when it does change:
You'll also need to create a Predefined Logic which calculates today's date:
And then you can put that all together with a Conditional Logic which will be the Price to pay:
Et voila - use that Price to pay Logic as the price which is passed to PayBridge and displayed to the user by way of Placeholder variables on the page. You can test it by setting that date to different dates in the past and future from your actual price change date.
I assume there will be a similar technique which can be used for Drupal Webforms but I've not yet learned it myself, so if you've got an article about that let me know and I'll link to it here. Similarly if you've got a different way to do this in Jadu I'll be interested to read it and link to it.
