Is it possible to place a Regex on a parameter value

Question

Is it possible to use Regex to force a edit box parameter value to a specific format?

Forcing a user to input an alphanumeric as (###) ###-####

Hello,

Unfortunately, there is no such possibility. However, thank you for the suggestion. We forwarded it to the corresponding department for consideration.

Is there a script that you are aware that can check the value of the field and then correct it with the necessary regex formatting?

Hello,

You can use an approach like the following with the below script in the If PowerShell script returns true condition.

$regularExpression = "^[0-9]{3}\-[0-9]{3}$"
$Context.ConditionIsMet = "%param-myParameter%" -notmatch $regularExpression

I would prefer to not stop the action altogether. I suppose there isn't a way to rewrite the value in the script with the proper formatting? I am sure it's possible, but if that's programatically intensive I am fine researching on my own. Just didn't know if there were already existing conditions where you could pass the parameter value to another value and force it into compliance in between using regex.

Hello,

In general it is possible to change the format of a string using the Split method. However, it will require users to at least enter the proper number of digits into the parameter. As such, you can use a condition script to check the parameter length and cancel the custom command execution if it does not equal 10. Another script will take the parameter value and update it according to the required format before setting to a property. The following article should be helpful: https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_split?view=powershell-7.4. Finally, the custom command should look like the following: If the approach does not meet your needs, please, describe the desired behavior in all the possible details with live examples and screenshots.

I will take a look. I think I can make something work with split. I'll post the results here.

On a sidenote, you could add the minimum character requirement on text parameters much like you do on property patterns. That would streamline things and remove the need for an additional script.
