PhoneFormatter.cfc 1.0 in ColdFusion

I typically store phone numbers in one field instead of using a separate field for each part of a phone number

Steve Bryant's Blog

I typically store phone numbers in one field (instead of using a separate field for each part of a phone number). While this usually works quite well, I have discovered that it can cause issues when I want a phone number to display in the same format regardless of how it was originally entered.

This is relatively easy to do if you handle it as the data comes in, but if you don't (either as oversight or because the data comes from outside the system) then it is a more difficult task.

I created PhoneFormatter to handle this task. Actually, it can handle formatting the data on an individual string or on a field across a whole table.

PhoneFormatter does require DataMgr. It also requires you to pass in the format you want to use for the phone number (using zeros as place-holders for digits). You should also pass in a default area code for numbers that don't have one. So the arguments for the init() method are:

  • DataMgr: An instantiated DataMgr component
  • Format: The desired format for phone number (using zeros as place holders for digits)
  • DefaultAreaCode: (optional) The area code you want PhoneFormatter to assign to phone numbers that don't have one.

To format a single phone number, pass it to the fixPhoneNumber() function (optionally passing in an area code as a separate argument).

To format every row for one field in a table, use the fixPhoneNumbers() method.

  • table: The name of the table in which you have the phone number.
  • idfield: The primary key field for the table.
  • phonefield: The field in the table in which you have the phone number.

PhoneFormatter may not solve a problem that you have, but if it does it can certainly be useful.

It is open source and free for any use. Feel free to download PhoneFormatter and try it out.

IoT & Smart Cities Stories
Every organization is facing their own Digital Transformation as they attempt to stay ahead of the competition, or worse, just keep up. Each new opportunity, whether embracing machine learning, IoT, or a cloud migration, seems to bring new development, deployment, and management models. The results are more diverse and federated computing models than any time in our history.
At CloudEXPO Silicon Valley, June 24-26, 2019, Digital Transformation (DX) is a major focus with expanded DevOpsSUMMIT and FinTechEXPO programs within the DXWorldEXPO agenda. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term. A total of 88% of Fortune 500 companies from a generation ago are now out of business. Only 12% still survive. Similar percentages are found throug...

Digital Transformation is much more than a buzzword. The radical shift to digital mechanisms for almost every process is evident across all industries and verticals. This is often especially true in financial services, where the legacy environment is many times unable to keep up with the rapidly shifting demands of the consumer. The constant pressure to provide complete, omnichannel delivery of customer-facing solutions to meet both regulatory and customer demands is putting enormous pressure on...
IoT is rapidly becoming mainstream as more and more investments are made into the platforms and technology. As this movement continues to expand and gain momentum it creates a massive wall of noise that can be difficult to sift through. Unfortunately, this inevitably makes IoT less approachable for people to get started with and can hamper efforts to integrate this key technology into your own portfolio. There are so many connected products already in place today with many hundreds more on the h...
The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications. Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addr...
