Issue
Out-of-the-box there exists a field type "Phone Number (E164)" that can be used to validate phone number formats. This is specific only for normal fields and not for variables as a similar type does not exist for variables.
This article details the steps that can be used as a workaround to validate phone number formats for variables. The solution makes use of a Single Line Text variable type and an onChange client script.

Resolution
- Create a variable of Single Line Text type.
- Create the following onChange client script:
-
- Type: onChange
- Variable name: the name of the variable to be used
- Script:
function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Type appropriate comment here, and begin script below
var pattern = /^[(]?(\d{3})[)]?[-|\s]?(\d{3})[-|\s]?(\d{4})$/;
if (!pattern.test(newValue)) {
alert('Phone enter a valid phone number');
g_form.setValue('variable_name', '');
}
}
*Please note that the above regex / pattern is specific for validating 10 integer digits only. You may modify this regex if there's a need for it to validate any other formats.
