I want to set some session variables early on such as _id etc. All I am trying to do is if the user is logged in, I want to get some other details in the session. But the database query keeps returning “Undefined”. Help !
Here’s the code
if(wixUsers.currentUser.loggedIn) {
$w(“#loginButton”).label = “Logout”;
$w(“#profileButton”).show();
//$w(“#readersButton”).show();
let userId = wixUsers.currentUser.id;
session.setItem(“userId”, userId);
wixData.query(“User”).eq(“_id”, userId)
.find()
.then( (results) => {
if (results.items.length === 0) {
console.log (“IN ONREADY. NOTHIG RETURNED”);
}
let value = results.items[0].value;
console.log("IN ON READY. HERE IS WHAT I GOT")
console.log(value);
// userRole = useritem._id;
} )
.catch( (err) => {
let errorMsg = err;
console.log (errorMsg);
} );
}
And here is what I see in the log

I assume you are doing import {session} from ‘wix-storage’; ?
You need to put all the stuff that is dependent on the results of the query, inside the .then( )
i.e. put
let value = results.items[0].value;
console.log(“IN ON READY. HERE IS WHAT I GOT”)
console.log(value);
inside the then.
Alternatively you can check out aysnc and await , which is far superior to .then( ) stuff, for mine.
Wix documentation being as hard to find as it is, though, the basic idea is:
in your onReady, change it to
onReady( async function( … etc
And when you do asynchronous code like queries, change it to
var results = await wixData.query(“User”).eq(“_id”, userId)
.find();
/* use the results here */
No more messy “thens”, you can treat the code in a normal (synchronous) manner.
Thank you Mike. The fix was much simpler though. It seems like I was calling the items collection incorrectly. Instead of
let value = results.items[0].value;
I corrected the actual value of the field and it worked
results.items[0].usertype
Well. that’s good that you “fixed it”, but you should still do what I recommended above, or you will get unpredictable results. It may seem fine, but sometimes it will give errors.
Hi Mike, just want to let you know that your insight on async and await saved my day. The WIX documentation is not great and I wish I had a way to let the world know this amazing function exists so they are not going crazy with their Wix collections.
You’re welcome Vidya, happy to help.
The next time I have a Wix question I going straight to you 
Please guys, i have a similar issue.
I tryed the follow code, but wasnt able to return the value of emailCP field, and with sure, for the tested _owner the database has a emailCP value.
$w.onReady(function () {
let user = wixUsers.currentUser;
userId = user.id;
user.getEmail()
.then((email) => {
userEmail = email;
$w(‘#textTest’).text = userEmail;
wixData.query(“ClienteParceiro”)
.eq(“_owner”, userId)
.find()
.then((results) => {
let item = results.items[0];
let emailCP = item.emailCp;
$w(‘#textTest3’).text = emailCP;
})
.catch((err) => {
let errorMsg = err;
});
$w(‘#textTest2’).text = userId;
console.log(userEmail);
console.log(userId);
});
About the async tip, i try the follow code, but wif sure, i did wrong.
async function getUserData(){
userId = await wixUsers.currentUser.id;
userEmail = await wixUsers.currentUser.getEmail();
console.log(userId, userEmail); }
Hi Daniel,
If userEmail is the one returned as “undefined” you should try the async in your main function call
$w.onReady(async function () {
let user = wixUsers.currentUser;
userId = user.id ;
await user.getEmail()
Hi Vidya, thanks by the reply!
I found my mistake… was at the database permissions. Always is a detail that take several hours of our time… But, im glad that is work now.
I liked the async function… leves the code clean, and i used that.
