title: How to link custom form fields to a user's profile?
body: <p>So I want to make a form that allows the registered users of my website to change their website URL. The website URL I'm referring to is the website field that can be seen in User -&gt; Edit page (<a href="https://i.stack.imgur.com/hJbvN.jpg" rel="nofollow noreferrer">the 'website URL' I'm referring to</a>). At the moment, I have a form created using a widget that allows me to receive someone's website URL, however, it does not automatically fill in their profile's website URL.</p>
  <p>What would be the most appropriate way to 'connect' the data from the form to the user-url field? <a href="https://i.stack.imgur.com/j4Akb.jpg" rel="nofollow noreferrer">Here</a> is a screenshot of what I'm trying to achieve.</p>
