Duplicate Validation for Portal Form

(0) ShareShare
ReportReport
Posted on by

Hi,

I am trying to add validations for a field in the web forms where it shouldn't allow email address duplication in the system. I am not sure how to add the validation. Can someone help me with this?

//Email Validator
            var emailValidator = document.createElement('span');
            emailValidator.style.display = "none";
            emailValidator.id = "emailaddressValidator";
            emailValidator.controltovalidate = "emailaddress1";
            emailValidator.errormessage = "The email you have entered is already in the system. PLease enter a different email address.";
			emailValidator.validationGroup = ""; // Set this if you have set ValidationGroup on the form
            emailValidator.initialvalue = "";
            emailValidator.evaluationfunction = function() {
                // only require email address if preferred contact method is email.
                if ($("#emailaddress1").val() == (NOT SURE HOW TO READ CRM DATA IN HERE)) {
                    return false;
                } else {
                    return true;
                }
            };

    Hi Harsha,

    The ideal solution for restricting the duplicate emails in the system is to write a plugin that will run on the server-side and restricts the user if an email address already exists in the system.

    To allow plugin validation messages to be visible in the portal form, you need to create a Site Setting called: Site/EnableCustomPluginError and set the value as True.

    Hope this helps!
