Linking a button to dynamic page can also be done like →
let user = wixUsers.currentUser;
let userId = user.id;
wixData.query("UserProfileData")
.eq("userId", userId)
.find()
.then( (results) => {
if(results.items.length > 0) {
let items = results.items[0]['link-userprofiledata-all']; // this is the field of link.
console.log("let items is " + items);
let id = `${items}`
console.log("let id is " + id);
wixLocation.to(`${items}`);
}
} );
