I successfully have it working, but I’m wandering if there is anyway to make the referral code there first and last initials and the last four of there phone number?

here’s the codes:

for the Profile Page

import wixData from ‘wix-data’;
$w.onReady(function () {
$w(“#updateProfile”).onReady( () => {
let isEmpty = $w(“#updateProfile”).getCurrentItem();
let theName = $w(“#firstName”).value;
if ( isEmpty === null ) {
$w(“#createProfileButton”).show();
$w(“#updateProfileButton”).hide();
$w(“#profileArea”).collapse();
$w(“#welcomeUser”).text = Welcome New User. Please create a profile!;
} else {
$w(“#updateProfileButton”).show();
$w(“#welcomeUser”).text = Welcome ${theName};
$w(“#profileArea”).expand();
}
} );
$w(“#updateProfile”).onAfterSave( () => {
let theName = $w(“#firstName”).value;
$w(“#welcomeUser”).text = “Update Completed!”;
const millisecondsToDelay = 2500;
setTimeout(() => {
$w(“#welcomeUser”).text = Welcome ${theName};
}, millisecondsToDelay);
});
});





for the Sign Up Page

import wixUsers from ‘wix-users’;
import wixData from ‘wix-data’;
import wixLocation from ‘wix-location’;
$w.onReady(function () {
let user = wixUsers.currentUser;
let userId = user.id; // “r5cme-6fem-485j-djre-4844c49”
let isLoggedIn = user.loggedIn; // true
user.getEmail()
.then( (email) => {
let userEmail = email;
$w(“#emailText”).value = userEmail;
let referralCode = userId.split(“-”)[4];
$w(“#referralCode”).text = referralCode;
} );
$w(“#createProfileButton”).onClick( () => {
let toInsert = {
“firstName”: $w(“#firstName”).value,
“lastName”: $w(“#lastName”).value,
“emailAddress”: $w(“#emailText”).value,
“phone”: $w(“#phone”).value,
“username”: $w(“#username”).value,
“referredBy”: $w(“#referredBy”).value,
“referralCode”: $w(“#referralCode”).text
};
wixData.insert(“profile”, toInsert)
.then( () => {
wixLocation.to(“/account/profile-page”);
} )
.catch( (err) => {
let errorMsg = err;
$w(“#error”).show();
} );
});
});

I sent her a email ty. I’m brand new to Corvid code. I have the profile and referral system working just don’t know how to make it use a different part such as initials for the referral code!
