Formatting Text Field with numbers and letters

Posted on by abubakrkhanaka

A simple solution but I cant find it anywhere.

I have a text input named postal code that must contain both numbers and letters and the format should be "### ###" for the user to proceed. I want to apply the condition on a label to show if the format is incorrect. I know how to do it for numbers or text only, but not both.

Thanks for the help in advance!

Hi @abubakrkhanaka ,
Validation checking can be achieved using Regex for Matching purpose.
You can use a label as such to check out if this is acceptable for your requirement.
Text property of Label
If(IsMatch(TextInput.Text, "^([a-zA-Z0-9]+ )([a-zA-Z0-9]+)*$") && Len(TextInput.Text) = 7, "Valid", "Invalid")

(Note: TextInput is the field where input will be entered and label will check, you can use the code for anywhere as per convenience)

Hope this helps
