So they land on a dynamic page, and you want to redirect them to another link in a database field called url? Is that right?
I haven’t tested this, but I’m guessing you could use getCurrentItem and then just send them to the url field. Something like the code below.
$w("#yourDataset").onReady(() => {
let currentItem = $w("#yourDataset").getCurrentItem();
let link = currentItem.url;
wixLocation.to(link);
})
Good luck!
